      description => protected'Plastic pollution is a pervasive and growing global problem. Chemicals in pl
         astics are often not sufficiently considered in the overall strategy to prev
         ent and mitigate the impacts of plastics on human health, the environment an
         d circular economy. Here we present an inventory of 16,325 known plastic che
         micals with a focus on their properties, presence in plastic and hazards. We
          find that diverse chemical structures serve a small set of functions, inclu
         ding 5,776 additives, 3,498 processing aids, 1,975 starting substances and 1
         ,788 non-intentionally added substances. Using a hazard-based approach, we i
         dentify more than 4,200 chemicals of concern, which are persistent, bioaccum
         ulative, mobile or toxic. We also determine 15 priority groups of chemicals,
          for which more than 40% of their members are of concern. Finally, we examin
         e data gaps regarding the basic properties, hazards, uses and exposure poten
         tial of plastic chemicals. Our work maps the chemical landscape of plastics 
         and contributes to setting the baseline for a transition towards safer and m
         ore sustainable materials and products. We propose that removing known chemi
         cals of concern, disclosing the chemical composition and simplifying the for
         mulation of plastics can provide pathways towards this goal.' (1276 chars)

      description => protected'Organic micropollutants in combined sewer overflows (CSOs) pose a potential 
         risk to aquatic ecosystems. Previous studies mainly reported event mean conc
         entrations (EMCs) and often focused on a small number of substances. This st
         udy presents realistic exposure scenarios using high-temporal resolution (10
         -minute) data from 24 events at two CSO sites. We analyzed 49 dissolved orga
         nic micropollutants for all events and 198 for four events, including pharma
         ceuticals, pesticides, and road-related compounds, of which we detected 83 s
         ubstances at least once. From these, we assessed the mixed chemical risk by 
         applying acute quality criteria and evaluated how the risk assessment outcom
         e changes for two aspects: temporal resolution and selection of substances. 
         Our results reveal that total risk quotients (RQ<sub>tot</sub>) can vary gre
         atly within CSO events, with 10-minute data capturing peak concentrations th
         at are missed with EMCs. Using EMCs underestimates the maximum RQ<sub>tot</s
         ub> of an event by a median factor of 4.9, up to a maximum factor of 6.9. Wh
         en comparing a selection of 20 substances from the Swiss Waters Protection O
         rdinance to a broader list of 49 substances commonly detected at CSOs and a 
         comprehensive list of 198 substances, the estimated RQ<sub>tot</sub> increas
         es between 1.1 to 2.3-fold. RQ<sub>tot</sub> values exceed the threshold of 
         1 in 75 % of the events, requiring further dilution in the receiving water b
         ody. All three pollutant classes (pharma, pesticide, road) drive the total r
         isk, and no specific phase during overflow events consistently poses higher 
         risk than other phases, which challenges the design of effective mitigation 
         measures. Furthermore, the exposure scenarios presented here offer essential
          input for future ecotoxicological research as they reveal high short-term f
         luctuations in RQ<sub>tot</sub> whose ecological significance is still large
         ly unknown.' (1911 chars)

      description => protected'Arsenic (As) is naturally present in trace amounts in most soils and poses a
          public health risk when elevated in topsoil due to potential accumulation i
         n agricultural products. Europe has several regions with natural As enrichme
         nt in soils, but since soil analyses are limited to individual soil samples,
          information on the spatial distribution has been lacking. This study uses e
         xpert-based machine learning to create a high-resolution map of As exceeding
          20 mg/kg in European topsoil based on ∼4100 data points of the Geochemi
         cal Mapping of Agricultural and Grazing Land Soil in Europe (GEMAS) dataset 
         and 15 environmental variables. The resulting pan-European probability map d
         elineates areas with high soil arsenic concentrations due to natural process
         es. The study finds that 11.7 % of grassland and 3.9 % of cropland in Eu
         rope have arsenic levels above this threshold, with France, Spain, the Weste
         rn Balkans, and mountain areas most affected. Commonly grown crops in these 
         areas include wheat, maize, rapeseed, and fodder crops. Our research links e
         levated arsenic levels to areas with low soil water erosion. SHapley Additiv
         e exPlanations (SHAP) analysis was used to identify key predictors, which ma
         y also be relevant in other regions globally. The high-resolution As map off
         ers valuable insights for agricultural and health professionals and policy-m
