communication tool that presents urban water supply and management in a simp
le visualization. Rapid urbanization, growing populations, and the climate c
risis increase the pressure on water resources, particularly in urbanized ar
eas. The WFD aims to foster a dialogue around conflict of interests and oppo
rtunities among different stakeholders, and trigger actions toward more sust
ainable urban water management (UWM), as well as a water secure future.<br /
><em>Method</em>: The WFD is produced from data on water abstraction, water
use of different sectors, water treatment, water recycling and contamination
risks. The data were obtained from government services, wastewater and wate
r utilities, large industries, universities and reports of intergovernmental
organizations. If these sources did not have data, reports from NGOs or con
sultants, comparable contexts, default values or expert judgements were cons
idered. The annual water flows are presented in a Sankey Diagram. An intuiti
ve color code highlights the flows as “problematic” or “appropriate”
and points to areas where UWM practices should be improved.<br /><em>Result
s and conclusions</em>: The final diagrams are a concise instrument that ide
ntifies challenges of UWM in the four application cases presented in this ar
ticle. Key challenges that became evident included: pollution from agricultu
ral production, the lack of wastewater and sanitation infrastructure, high w
ater losses in the distribution networks, water exports leading to a lack in
local supply and sewer overflows during heavy rainfalls. Opportunities iden
tified were the need to: invest in sanitation and wastewater to protect reso
urces, create coordination bodies to align conflict of interests, and/or inv
est in blue-green infrastructure for rainwater retention. The WFD triggered
local actions, such as in-depth discussions between relevant actors, the for

showing that the likelihood of such transitions increases with the number o

s thus shift the question from the classical question of what makes complex,
unaltered ecosystems stable to whether the effects of, known and unknown, s

presents a top-down method that expands the existing Global Resilience Analy

(GI) types (bioretention cells, green roofs, and permeable pavements) over 3
8 years. The results demonstrated that GI enhanced all resilience indices, w
ith variations observed in individual CSO performance metrics and their syst

the highest resilience enhancement. Overall, our proposed method enables a

is often considered an inherent benefit rather than a core planning requirem

idors for otherwise fragmented habitats is undisputed. While quantitative ap
proaches for modelling ecological connectivity in conservation planning are
well established, mismatches in scope and scale with models that support the
planning of BGI makes their adoption and integration difficult across disci
plines. Technical complexities have led to ambiguity around circuit and netw
ork-based approaches, focal node placement, spatial extents, and resolution.
Furthermore, these approaches are often computationally intensive, and cons
iderable gaps remain in their use for identifying local-scale critical "pinc
h-points" that urban planners may respond to with the integration of BGI int

ces. Here, we present a framework that simplifies and integrates the merits
of regional connectivity assessments with a focus on urban areas to prioriti

regional scale, (2) prioritising local-scale BGI interventions based on the
relative contribution of individual nodes in this regional network, and (3)
inferring connectivity hot- and cold-spots for local-scale BGI interventions

Focusing on the two largest scales of heterogeneity in these systems, indiv

structured and disordered three-dimensional fracture networks with varying
degrees of hydraulic heterogeneity. For the moderate levels of hydraulic het
erogeneity we consider, network structure is the dominant control of transpo

is observed in structured networks than in disordered networks, due in part
to the higher connectivity in the former, independent of the level of hydrau

works, thereby indicating that the interplay between structural and hydrauli

a weighted graph representation of the networks, where the weights are give

The water flow diagram
Method: The WFD is produced from data on water abstraction, water use of different sectors, water treatment, water recycling and contamination risks. The data were obtained from government services, wastewater and water utilities, large industries, universities and reports of intergovernmental organizations. If these sources did not have data, reports from NGOs or consultants, comparable contexts, default values or expert judgements were considered. The annual water flows are presented in a Sankey Diagram. An intuitive color code highlights the flows as “problematic” or “appropriate” and points to areas where UWM practices should be improved.
Results and conclusions: The final diagrams are a concise instrument that identifies challenges of UWM in the four application cases presented in this article. Key challenges that became evident included: pollution from agricultural production, the lack of wastewater and sanitation infrastructure, high water losses in the distribution networks, water exports leading to a lack in local supply and sewer overflows during heavy rainfalls. Opportunities identified were the need to: invest in sanitation and wastewater to protect resources, create coordination bodies to align conflict of interests, and/or invest in blue-green infrastructure for rainwater retention. The WFD triggered local actions, such as in-depth discussions between relevant actors, the formation of integrated water use committees and the interest of the national ministry in Senegal to replicate the diagram for other locations. This article presents the methodology, discusses the four case studies and deliberates on the prospective use of the WFD.

Sanitation systems. Are hybrid systems sustainable or does winner takes all?
Current evidence indicates that, depending on the settlement structure, centralized systems can have diseconomies of scale, and modelling studies show that there are conditions where hybrid systems are cost-effective. Decisive factors are the costs of modular systems and the heterogeneity of urban areas. Overall, there are good reasons to believe that fortifying centralized systems with modular systems enable overcoming some of the critical weaknesses of the one-size-fits-all centralized systems approach.
However, centralized systems show strong path dependencies. Besides a wide range of institutional and organizational barriers, current engineering economic and planning methodologies also need to be improved and adapted. From a purely engineering perspective, the following research needs can be identified: (i) long-term transition planning tools that are spatially explicit and can consider a wide range of modular technologies; (ii) cross-sectoral integration methodologies; (iii) better methods to integrate multi-criteria decision analysis (MCDA) to consider the broader range of benefits hybrid systems can provide; and (iv) improved engineering economic methodologies considering uncertainties, unused capacity, and the value of adaptability.

cides target the cholinergic system. Across phyla, cholinergic signaling is
essential for many neuro-developmental processes including axonal pathfindin
g and synaptogenesis. Consequently, early-life exposure to such insecticides
can disturb these processes, resulting in an impaired nervous system. One t
est frequently used to assess developmental neurotoxicity is the zebrafish l
ight–dark transition test, which measures larval locomotion as a response
to light changes. However, it is only poorly understood which structural alt
erations cause insecticide-induced locomotion defects and how persistent the
se alterations are. Therefore, this study aimed to link locomotion defects w
ith effects on neuromuscular structures, including motorneurons, synapses, a
nd muscles, and to investigate the longevity of the effects. The cholinergic
insecticides diazinon and dimethoate (organophosphates), methomyl and pirim
icarb (carbamates), and imidacloprid and thiacloprid (neonicotinoids) were u
sed to induce hypoactivity. Our analyses revealed that some insecticides did
not alter any of the structures assessed, while others affected axon branch
ing (methomyl, imidacloprid) or muscle integrity (methomyl, thiacloprid). Th
e majority of effects, even structural, were reversible within 24 to 72 h. O
verall, we find that both neurodevelopmental and non-neurodevelopmental effe

Erhebung der Fischbiodiversität in Schweizer Fliessgewässern. "Progetto Fiumi" Schlussbericht
Aufgrund der geografischen Lage in vier der wichtigsten Wassereinzugsgebieten Europas und der grossen Vielfalt an Lebensräumen weisen die aquatischen Ökosysteme der Schweiz eine aussergewöhnlich hohe Fischvielfalt auf. Diese Vielfalt ist hauptsächlich durch zwei verschiedene Prozesse entstanden, einerseits durch die Zusammenführung bereits vorhandener Vielfalt, und andererseits durch postglaziale Evolutionsprozesse. Der letztgenannte Prozess hat zu einem hohen Grad an Endemismus vor allem in den grösseren Seen des Alpenraums geführt. Diese einzigartige Vielfalt ist auf vielen verschiedenen Ebenen zu finden. Neben der Artenvielfalt beherbergen die verschiedenen Flüsse und Bäche auch eine Vielfalt an diversen Fischgemeinschaften, wobei sowohl die Unterschiede in der Artenzahl als auch in der Artenzusammensetzung zu unterschiedlichen Nahrungsnetzen und Ökosystemprozessen zwischen den Flüssen führen. Viele Fischarten weisen auch ein hohes Mass an intraspezifischer Vielfalt auf, z. B. in Bezug auf Morphologie, Physiologie, Ökologie, Lebensgeschichte und Genom. Diese intraspezifische Vielfalt ist insofern von Bedeutung, dass verschiedene Populationen möglicherweise an unterschiedliche Lebensräume angepasst sind und eine hohe genetische Vielfalt aufweisen. Letzteres ermöglicht es den einzelnen Individuen innerhalb einer Population, verschiedene Nischen zu besetzen, und es ermöglicht den Populationen, sich besser an veränderte Umweltbedingungen anzupassen.

The unique fish diversity in riverine ecosystems in and around Switzerland
As a consequence of its geographic location within four of Europe’s major watersheds and a large amount of habitat diversity, aquatic ecosystems in Switzerland harbor an exceptionally high amount of fish diversity. This diversity has mainly been formed by two different processes, i.e. assembly of previously existing diversity and postglacial evolutionary processes. The latter of these processes has led to a high degree of endemism in especially the larger lakes in the Alpine region. The unique diversity can be found on many different levels. Besides the diversity of species, the different rivers and streams also harbor a diversity of fish communities, where both the variation in the number of species and the composition of species result in different food webs and ecosystem processes between rivers. Many of the fish species also show a high degree of intraspecific diversity in e.g. morphology, physiology, ecology, life history and in their genome. This intraspecific diversity is important in terms of different populations potentially being adapted to different habitats and in terms of populations harboring a high genetic diversity. The latter makes the individual fish within a population able to occupy different niches and makes the populations better able to adapt to changing environmental conditions. [...]

The importance of indirect effects of climate change adaptations on alpine and pre‐alpine freshwater systems
2. The direct effects of climate change, such as increased temperatures and higher frequency of extreme meteorological events, interact with human responses to climate change, which we refer to here as 'indirect effects'. The latter possibly have even greater impact than the direct effects of climate change. Specifically, changes in land-use practices as responses to climate change, such as adjusted cropping regimes or a shift to renewable hydroelectricity to mitigate climate change, can very strongly affect freshwater ecosystems.
3. Hitherto, these indirect effects and the possibility of idiosyncratic outcomes are under-recognized. Here, we synthesize knowledge and identify threats to freshwater environments in alpine and pre-alpine regions, which are particularly affected by climate change.
4. We focus on the effects of adapted agriculture and hydropower production on freshwater quality and ecological status, as these examples have strong indirect effects that interact with direct effects of climate change (e.g., water temperature, droughts, isolation of populations).
5. We outline how failure to effectively account for indirect effects associated with human responses to climate change may exacerbate direct climate change impacts on aquatic ecosystems. If managed properly, however, human responses to indirect effects offer potential for rapid and implementable leverage to mitigate some of the direct climate change effects on aquatic ecosystems. To better address looming risks, policy- and decisionmakers must account for indirect effects and incorporate them into restoration planning and the respective sectorial policies.
Besserer Biodiversitätsschutz in Blau-Grünen Ökosystemen. Des écosystèmes bleus-verts pour mieux protéger la biodiversité
Bien qu’ils soient interdépendants, les écosystèmes aquatiques (bleus) et terrestres (verts) sont trop souvent appréhendés isolément les uns des autres. Pour que la conservation de la biodiversité soit plus efficace, la recherche, la pratique et la législation doivent dépasser cette approche cloisonnée au profit d’une vision inter-écosystémique.

Le Projet Lac était un grand projet de l'Eawag et de l'Université de Berne visant à recenser pour la première fois
de manière quantitative des communautés entières de poissons dans les grands et profonds lacs des Alpes européennes et de leurs environs, à l'aide de méthodes d'échantillonnage standardisées. A partir de 2010, 35 lacs au total ont été étudiés en Suisse, en Italie, en France, en Allemagne et en Autriche et plus de 106 espèces de poissons ont été recensées. Ce rapport résume les principaux résultats, compare les communautés de poissons des différents lacs, examine leur relation avec les paramètres environnementaux et donne un aperçu des facteurs qui influencent la diversité biologique et la structure des communautés dans cet écosystème important.
Il Projet Lac era un progetto su larga scala dell'Eawag e dell'Università di Berna per la prima indagine quantitativa di intere comunità di pesci in laghi grandi e profondi nelle Alpi europee e dintorni, utilizzando metodi di campionamento standardizzati. A partire dal 2010, un totale di 35 laghi in Svizzera, Italia, Francia, Germania e Austria sono stati studiati e sono state registrate oltre 106 specie di pesci. Questo rapporto riassume i risultati principali, confronta le comunità di pesci di ogni lago, esamina la loro relazione con i parametri ambientali e fornisce una panoramica dei fattori che influenzano la biodiversità e la struttura della comunità in questo importante ecosistema.

Starting in 2010, in total 35 lakes were investigated across Switzerland, Italy, France, Germany and Austria, with more than 106 fish species recorded. This report brings together key findings, compares fish communities among lakes, investigates their relationship to environmental parameters, and provides an overview of drivers of biodiversity and community structure in this important ecosystem.
Sub-lethal peak exposure to insecticides triggers olfaction-mediated avoidance in zebrafish larvae
A ribonucleoprotein transfection strategy for CRISPR/Cas9‐mediated gene editing and single cell cloning in rainbow trout cells
Results: Ribonucleoprotein (RNP) complexes, consisting of the Cas9 protein and a fluorescently labeled crRNA/tracrRNA duplex targeting the cyp1a1 gene, were delivered via electroporation. A T7 endonuclease I (T7EI) assay was performed on flow cytometry enriched transfected cells in order to detect CRISPR-mediated targeted mutations in the cyp1a1 locus, revealing an overall gene editing efficiency of 39%. Sanger sequencing coupled with bioinformatic analysis led to the detection of multiple insertions and deletions of variable lengths in the cyp1a1 region directed by CRISPR/Cas9 machinery. Clonal isolation based on the use of cloning cylinders was applied, allowing to overcome the genetic heterogeneity created by the CRISPR/Cas9 gene editing. Using this method, two monoclonal CRISPR edited rainbow trout cell lines were established for the first time. Sequencing analysis of the mutant clones confirmed the disruption of the cyp1a1 gene open reading frame through the insertion of 101 or 1 base pair, respectively.
Conclusions: The designed RNP-based CRISPR/Cas9 approach, starting from overcoming limitations of transfection to achieving a clonal cell line, sets the stage for exploiting permanent gene editing in rainbow trout, and potentially other fish cells, for unprecedented exploration of gene function.
The vulnerability of lakes to climate change along an altitudinal gradient
Anwendung von eDNA-Methoden in biologischen Untersuchungen und bei der biologischen Bewertung von aquatischen Ökosystemen. Richtlinien
Aquatic biomonitoring is currently transformed by environmental DNA (eDNA) based approaches. These new tools overcome some limitations of traditional biomonitoring and allow non-invasive sampling, broad taxonomic coverage, high sensitivity, and the possibility to automation. However, the disruptive character and rapid developments of the new technology challenge its implementation. This publication explains the principles of the eDNA technology and presents its advantages and limitations. It shows possible applications of eDNA tools in monitoring and assessment of aquatic ecosystems, and provides detailed protocols and best practices for processing eDNA samples.

assess the microbial quality of the reclaimed water at a high temporal reso

quality, even in these best-in-class systems, rendering the water inadequate
for the intended reuse applications (toilet flushing and landscape irrigati

ncy of chlorination, and (2) fluctuations of the chlorine demand of the wate
r, in particular of ammonium concentrations. Such fluctuations are likely in
herent to on-site systems, which rely on a low level of process control. The
monitoring campaign showed that the microbial water quality was most closel

that treat the water for applications that go beyond the reuse scopes defin

WRF quality targets in small-scale and decentralized systems under economic

ion level due to many mild and asymptomatic cases and similar symptoms to ot
her common circulating respiratory diseases, including COVID-19. Methods for
tracking cases outside of typical reporting infrastructure could improve mo
nitoring of influenza transmission dynamics. Influenza shedding into wastewa
ter represents a promising source of information where quantification is unb
iased by testing or treatment-seeking behaviours. METHODS: We quantified inf
luenza A and B virus loads from influent at Switzerland's three largest wast
ewater treatment plants, serving about 14% of the Swiss population (1.2 mill
ion individuals). We estimated trends in infection incidence and the effecti
ve reproductive number (R<sub>e</sub>) in these catchments during a 2021/22
epidemic and compared our estimates to typical influenza surveillance data.
RESULTS: Wastewater data captured the same overall trends in infection incid
ence as laboratory-confirmed case data at the catchment level. However, the
wastewater data were more sensitive in capturing a transient peak in inciden
ce in December 2021 than the case data. The R<sub>e</sub>estimated from the
wastewater data was roughly at or below the epidemic threshold of 1 during w
ork-from-home measures in December 2021 but increased to at or above the epi
demic threshold in two of the three catchments after the relaxation of these
measures. The third catchment yielded qualitatively the same results but wi
th wider confidence intervals. The confirmed case data at the catchment leve
l yielded comparatively less precise R_e estimates before and during the wor
k-from-home period, with confidence intervals that included one before and d
uring the work-fromhome period. DISCUSSION: Overall, we show that influenza
RNA in wastewater can help monitor nationwide influenza transmission dynamic

on technology acceptance indicates perceived costs, risks, and benefits of

critical indicator to monitor disease dynamics, inform regional and national
policies, and estimate the effectiveness of interventions. It describes the
average number of new infections caused by a single infectious person throu
gh time. To date, R<sub>e</sub> estimates are based on clinical data such as
observed cases, hospitalizations, and/or deaths. These estimates are tempor
arily biased when clinical testing or reporting strategies change.<br /><em>
OBJECTIVES:</em> We show that the dynamics of severe acute respiratory syndr
ome coronavirus 2 (SARS-CoV-2) RNA in wastewater can be used to estimate R<s
ub>e</sub> in near real time, independent of clinical data and without the a
ssociated biases.<br /><em>METHODS:</em> We collected longitudinal measureme
nts of SARS-CoV-2 RNA in wastewater in Zurich, Switzerland, and San Jose, Ca
lifornia, USA. We combined this data with information on the temporal dynami
cs of shedding (the shedding load distribution) to estimate a time series pr
oportional to the daily COVID-19 infection incidence. We estimated a wastewa
ter-based R<sub>e</sub> from this incidence.<br /><em>RESULTS:</em> The meth
od to estimate R<sub>e</sub> from wastewater worked robustly on data from tw
o different countries and two wastewater matrices. The resulting estimates w
ere as similar to the R<sub>e</sub> estimates from case report data as R<sub

among each other. We further provide details on the effect of sampling freq

exposure to bypass-borne multi-resistance risk factors increase under stormw

entially mobile. In addition, elevated resistance risk factors persisted for
some time (up to 22 h) in the receiving water after stormwater events, lik

Groundwater salinity in the Horn of Africa: spatial prediction modeling and estimated people at risk
Methods: Machine learning (random forest) is used to make spatial predictions of salinity levels at three electrical conductivity (EC) thresholds using data from 8646 boreholes and wells along with environmental predictor variables. Attention is paid to understanding the input data, balancing classes, performing many iterations, specifying cut-off values, employing spatial cross-validation, and identifying spatial uncertainties.
Results: Estimates are made for this transboundary region of the population potentially exposed to hazardous salinity levels. The findings indicate that about 11.6 million people (∼7% of the total population), including 400,000 infants and half a million pregnant women, rely on groundwater for drinking and live in areas of high groundwater salinity (EC > 1500 µS/cm). Somalia is the most affected and has the largest number of people potentially exposed. Around 50% of the Somali population (5 million people) may be exposed to unsafe salinity levels in their drinking water. In only five of Somalia's 18 regions are less than 50% of infants potentially exposed to unsafe salinity levels. The main drivers of high salinity include precipitation, groundwater recharge, evaporation, ocean proximity, and fractured rocks. The combined overall accuracy and area under the curve of multiple runs is ∼ 82%.
Conclusions: The modelled groundwater salinity maps for three different salinity thresholds in the Horn of Africa highlight the uneven spatial distribution of salinity in the studied countries and the large area affected, which is mainly arid flat lowlands. The results of this study provide the first detailed mapping of groundwater salinity in the region, providing essential information for water and health scientists along with decision-makers to identify and prioritize areas and populations in need of assistance.

Routes and reservoirs of AMR-determinants & one health AMR-surveillance. Thematic synthesis of the national research programme "Antimicrobial Resistance"
The aim of the synthesis process on this topic was to derive recommendations from NRP 72 research that promote the implementation of new findings in practice. The focus of many projects was on the interfaces where antimicrobial resistance (AMR) can spread between humans, animals and the environment. In this One Health context, many research findings of NRP 72 provide the basis for concrete measures to interrupt or restrict transmission chains.
In addition to these concrete findings, it has also become apparent that the methods used in NRP 72 research are of great importance: It is a common feature of the projects presented in this thematic synthesis that they have applied new gene sequencing methods, such as whole genome sequencing (WGS), plasmid sequencing and metagenomics. These methods have developed very quickly in the last few years and are a prerequisite for the new insights presented here. [...]

Wastewater-based estimation of the effective reproductive number of SARS-CoV-2
OBJECTIVES: We show that the dynamics of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA in wastewater can be used to estimate Re in near real time, independent of clinical data and without the associated biases.
METHODS: We collected longitudinal measurements of SARS-CoV-2 RNA in wastewater in Zurich, Switzerland, and San Jose, California, USA. We combined this data with information on the temporal dynamics of shedding (the shedding load distribution) to estimate a time series proportional to the daily COVID-19 infection incidence. We estimated a wastewater-based Re from this incidence.
RESULTS: The method to estimate Re from wastewater worked robustly on data from two different countries and two wastewater matrices. The resulting estimates were as similar to the Re estimates from case report data as Re estimates based on observed cases, hospitalizations, and deaths are among each other. We further provide details on the effect of sampling frequency and the shedding load distribution on the ability to infer Re.
DISCUSSION: To our knowledge, this is the first time Re has been estimated from wastewater. This method provides a low-cost, rapid, and independent way to inform SARS-CoV-2 monitoring during the ongoing pandemic and is applicable to future wastewater-based epidemiology targeting other pathogens.

Keeping water from kiosks clean: strategies for reducing recontamination during transport and storage in Eastern Uganda
All three intervention strategies contributed to significantly lower E. coli recontamination levels after 24 h than in the control group (Median (Mdn) = 9 CFU/100 mL, Interquartile Range (IQR) = 25). Median E. coli counts and mean FRC consumption were higher in uncleaned jerrycans (Median = 1 CFU/100 mL, IQR = 6, ΔFRC = 1.8 mg/L) than in cleaned jerrycans (Median = 0 CFU/100 mL IQR = 2, ΔFRC = 1.6 mg/L) and the lowest in cleaned improved containers (Median = 0 CFU/100 mL, IQR = 0, ΔFRC = 1.2 mg/L). The FRC concentration at the tap of 2 mg/L was too low to protect water from E. coli recontamination in uncleaned jerrycans over 24 h. Cleaning the jerrycans was inconvenient due to their small openings, therefore, sand was used. The cleaning with sand reduced recontamination with E. coli but did not reduce the count of total coliforms. Improved containers with a larger opening allowed for cleaning with a brush and showed the lowest levels of recontamination for both E. coli and total coliforms. In addition to the intervention strategies, households receiving a higher number of WASH education visits within the previous year had lower recontamination levels of E. coli in stored water (OR = 0.54, p = .003).

Modeling in-sewer transformations at catchment scale – implications on drug consumption estimates in wastewater-based epidemiology
Assessing associated uncertainties typically requires numerous simulations. Therefore, we propose a new two-step modeling framework: 1) Quantify hydrodynamic conditions. This computationally demanding step was performed once in SWMM to derive HRT and A/Veq for each potential point of discharge (node) in three catchments of different size. 2) Estimate biomarker loss. In this step, Monte Carlo simulations were performed for defined scenarios. Depending on assumptions about drug user distribution and prevalence, a number of nodes was sampled. For each node an empirical first-order transformation model was applied with flow-path-corresponding HRT and A/Veq from step 1. Biotic and abiotic transformation rates were sampled from distributions combining variability of different biofilms.
In our modeling study, median losses were >30% for amphetamine, 6-monoacetylmorphine and 6-acetylcodeine in all three catchments with high uncertainty (5%–100% loss), which would imply a systematic underestimation of consumption when neglecting in-sewer processes. Median losses for 21 other investigated biomarkers were <10% with different uncertainty ranges – “no substantial transformation” was confirmed for nine substances in a real sewer segment with a 2-h residence time. Transferability of these results must be tested for other catchments. To further reduce uncertainty, mainly additional knowledge on transformation rates, particularly in biofilm, and their distribution across a sewer network is needed to update model input objectively. Our approach allows efficient testing and, furthermore, can be expanded for many other human biomarkers. Accounting for biomarker stability during in-sewer transport will avoid biased estimates and further improve wastewater-based epidemiology.

Reflection of socioeconomic changes in wastewater: licit and illicit drug use patterns
Spatial differences and temporal changes in illicit drug use in Europe quantified by wastewater analysis
Design. Analyses of raw wastewater over a 1-week period in 2012 and 2013.
Setting and Participants. Catchment areas of wastewater treatment plants (WWTPs) across Europe, as follows: 2012: 25 WWTPs in 11 countries (23 cities, total population 11.50 million); 2013: 47 WWTPs in 21 countries (42 cities, total population 24.74 million).
Measurements. Excretion products of five illicit drugs (cocaine, amphetamine, ecstasy, methamphetamine, cannabis) were quantified in wastewater samples using methods based on liquid chromatography coupled to mass spectrometry.
Findings. Spatial differences were assessed and confirmed to vary greatly across European metropolitan areas. In general, results were in agreement with traditional surveillance data, where available. While temporal changes were substantial in individual cities and years (P ranging from insignificant to <10−3), overall means were relatively stable. The overall mean of methamphetamine was an exception (apparent decline in 2012), as it was influenced mainly by four cities.
Conclusions. Wastewater analysis performed across Europe provides complementary evidence on illicit drug consumption and generally concurs with traditional surveillance data. Wastewater analysis can measure total illicit drug use more quickly and regularly than is the current norm for national surveys, and creates estimates where such data does not exist.
