Pesticide impacts are usually discussed in the context of applied amounts while disregarding large but environmentally relevant variations substance-specific toxicity. Here, we systemically interpret changes use 381 pesticides over 25 years by considering 1591 acute toxicity threshold values for eight nontarget species groups. We find that insecticides to aquatic invertebrates and pollinators has increased considerably-in sharp contrast amount-and this increase been driven highly toxic...
Aquatic ecosystems are at risk of being impaired by various organic chemicals, however comprehensive large-scale evaluations waterbodies' status and trends rare. Here, surface water monitoring data, gathered as part the EU Water Framework Directive comprising occurrence 352 contaminants (>8.3 mil. measurements; 2001–2015; 8213 sites) in 31 European countries, was used to evaluate past current environmental risks for three aquatic species groups: fish, invertebrates, plants. Monitoring...
Abstract Pesticides are transferred outside of cropland and can affect animals plants. Here we investigated the distribution 97 current use pesticides in soil vegetation as central exposure matrices insects. Sampling was conducted on 53 sites along eleven altitudinal transects Vinschgau valley (South Tyrol, Italy), Europe’s largest apple growing area. A total 27 (10 insecticides, 11 fungicides 6 herbicides) were detected, originating mostly from orchards. Residue numbers concentrations...
Expressing temporal changes in the use of pesticides, based not only on amounts (masses) but also their toxicity for different species groups, was proposed as a sensible approach evaluating potential environmental risks. Here, we calculated total applied (TAT) between 1995 and 2019 Germany, mapped it, compared it to US TAT other risk indicators. Results show that German terrestrial vertebrates decreased over time by about 20%. The increased factor three fishes, largely due insecticides, two...
Currently, there are more than 350,000 chemicals in use, while their ecological effects not fully understood. In this review, we focus on pesticides, pharmaceuticals, and personal care products discuss potential impact aquatic biodiversity ecosystem functions. We critically reflect strategies to reduce environmental release mitigate effects. Various mitigation available contaminant concentrations surface waters, but efficiency varies under the current procedures. Intervening at start of...
Although pesticide contamination in agricultural surface waters is a common phenomenon, large-scale studies dealing with the responsible drivers are rare. We used data from 259 publications reporting 5830 individual water or sediment concentrations of 32 insecticides and their metabolites 644 US to determine factors driving insecticide risks, that is, exceedance regulatory threshold levels (RTLs). Multiple linear regressions (R2 adj. = 49.6-76.5) revealed toxicity-normalized use (i.e....
Leaf litter is a major source of carbon and energy for stream food webs, while both leaf-decomposing microorganisms macroinvertebrate leaf shredders can be affected by fungicides. Despite the potential season-long fungicide exposure these organisms, however, such chronic exposures have not yet been considered. Using an artificial facility, effects (lasting up to 8 wk) mixture 5 fungicides (sum concentration 20 μg/L) on leaf-associated key shredder Gammarus fossarum were therefore assessed....
Abstract Pesticides enter non-target surface waters as a result of agricultural activities and may reach water bodies in protected areas. We measured southwestern Germany pesticide concentrations after heavy rainfalls streams drinking protection area near Hausen (Freiburg) the catchment Queich (Landau), which originates from biosphere reserve Palatinate Forest. On average, 32 (n = 21) 21 10) pesticides were detected per sample event 56) 17), respectively. The majority > 50% all samples...
Abstract Many studies have investigated short-term peak concentrations of pesticides in surface waters resulting from agricultural uses. However, we lack information to what extent reoccur over medium (> 4 days) and longer time periods 10 days). We use here large-scale pesticide monitoring data across Europe (~ 15 mil. measurements, i.e., quantified water at > 17,000 sites for 474 compounds) evaluate the degree which were not only detected once, but sequences a compound repeatedly same...
Assessing the impact of chemicals on environment and addressing subsequent issues are two central challenges to their safe use. Environmental data continuously expanding, requiring flexible, scalable, extendable management solutions that can harmonize multiple sources with potentially differing nomenclatures or levels specificity. Here, we present methodological steps taken construct a rule-based labeled property graph database, “Meta-analysis Global Impact Chemicals” (MAGIC) graph, for...
Regulatory threshold levels (RTL) represent robust benchmarks for assessing risks of pesticides, e.g., in surface waters. However, comprehensive scientific risk evaluations comparing RTL to measured environmental concentrations (MEC) pesticides waters were yet restricted a low number as are only available after extensive review regulatory documents. Thus, the aim present study was model equivalents (RTLe) aquatic organisms from publicly accessible ecotoxicological effect databases. We...
A complete ban on pesticide use in sensitive areas, such as nature conservation areas (NCA), is currently being debated the EU part of Sustainable Use Regulation. NCA are strictly protected landscapes Germany with minimal agricultural activity (<4.5 %) that serve vital ecological refuges. However, it largely unknown whether surface waters German contaminated by pesticides. The current study uses extensive monitoring data (n = 3,822,553 measurements, 1998–2020, 208 pesticides) from federal...
With an ever-increasing production and registration of chemical substances, obtaining reliable up to date information on their use types (UT) class (CC) is crucial importance. We evaluated the current status open access substance databases (DBs) regarding UT CC using “Meta-analysis Global Impact Chemicals” (MAGIC) graph as a benchmark. A decision tree-based selection process was used choose most suitable out 96 databases. To compare DB content for 100 weighted, randomly selected extensive...
