Abstract In Germany, the decline of insect biomass was observed in nature conservation areas agricultural landscapes. One main causal factors discussed is use synthetic pesticides conventional agriculture. a Germany-wide field study, we collected flying insects using Malaise traps adjacent to land. We used multi-component chemical trace element analysis detect 92 common ethanol from sampled May and August 2020. total, residues 47 current were detected, samples on average contaminated with 16.7 pesticides. Residues herbicides metolachlor-S, prosulfocarb terbuthylazine, fungicides azoxystrobin fluopyram recorded at all sites. The neonicotinoid thiacloprid detected 16 21 areas, most likely due final before an EU-wide ban. A change residue mixture composition noticeable higher herbicide spring increasing fungicide applications summer. number substances related proportion production area radius 2000 m. Therefore, drastic pesticide reduction large buffers around necessary avoid contamination their fauna.

River ecological status is shaped by agricultural land use intensity across Europe

Water Research, Journal Year: 2024, Volume and Issue: 251, P. 121136 - 121136

Published: Jan. 21, 2024

Agriculture impacts the ecological status of freshwaters through multiple pressures such as diffuse pollution, water abstraction, and hydromorphological alteration, strongly impairing riverine biodiversity. The agricultural effects, however, likely differ between types practices. In Europe, show distinct spatial patterns related to intensity, biophysical conditions, socioeconomic history, which have been operationalised by various landscape typologies. Our study aimed at analysing whether incorporating intensity enhances correlation land use status. For this, we aggregated continent's activities into 20 Areas Farming-induced Freshwater Pressures (AFFP), specifying individual pressure profiles regarding nutrient enrichment, pesticides, in riparian zone establish an index this river Using index, nearly doubled correlative strength agriculture rivers compared share sub-catchment (based on analysis more than 50,000 units). Strongest were found for high cropland Mediterranean Temperate regions, while extensive grassland, fallow farmland livestock farming Northern Highland well low mosaic farming, featured lowest pressures. results provide advice pan-European management freshwater ecosystems highlight urgent need sustainable agriculture. Consequently, they can also be used a basis European Union-wide global policies halt biodiversity decline, post-2027 renewal Common Agricultural Policy.

Freshwater ecosystems face a particularly high risk of biodiversity loss compared to marine and terrestrial systems. The use pesticides in agricultural fields is recognized as relevant stressor for freshwater environments, exerting negative impact worldwide on the overall status health communities.

A review of modeling pesticides in freshwaters: Current status, progress achieved and desirable improvements.

Environmental Pollution, Journal Year: 2022, Volume and Issue: 316, P. 120553 - 120553

Published: Nov. 5, 2022

This study comprises a critical review of modeling pesticides in surface waters. The aim was to update the status use models simulate fate from diffuse sources. ISI papers were selected on Scopus and information concerning areas, type (herbicides, fungicides insecticides), model, methodology adopted (i.e., calibration and/or validation, spatial temporal scales) analyzed. studies carried out Europe (55.5%), North America (22.3%), Asia (13.9%) South (8.3%). Soil Water Assessment Tool proved be most used model (45.95%). Herbicides modeled (71.4%), followed by insecticides (18.2%) (10.4%). main herbicides atrazine, metolachlor, isoproturon, glyphosate, acetochlor. Insecticides such as chlorpyrifos metaldehyde. Chlorothalonil, tebuconazole) widely investigated. Based published studies, it found that approaches for assessing are constantly evolving algorithms work well with diverse watershed conditions, management strategies, pesticide properties. Several reported concentrations exceeding ecotoxicological thresholds revealing water contamination agriculture urban areas is priority issue current global concern.

Abstract Background Chemical pollution forms a severe threat for human and environmental health. While the risks European lowland water bodies are well known, there is little knowledge on remote aquatic ecosystems particularly mountain lakes, despite their importance provision of freshwater. Here, we critically review current exposure risk by chemical lakes present tiered approach how to advance effectively our understanding in future. Results Generally, pollutant monitoring data currently incomplete, with many regions substances having been only poorly investigated. More reliable exist persistent organic pollutants (POPs). However, increasing evidence that even exposed wide range pollutants. Among them potent pesticides used agricultural biocidal applications, such as diazinon permethrin. The follows complex pattern. Pollutants introduced into via atmospheric deposition run-off from watershed, but also local sources, like tourism pastoralism. Our assessment recent biomonitoring studies suggest widespread chronic toxic crustacean ranges. If ranges pastoralism, acute effects possible. Thereby, vulnerability has be expected high due harsh conditions at altitudes, organism’s traits, insular position lower species richness altitudes. Furthermore, biological processes leading degradation under ecological ecosystems. Conclusion sensitivity investigated, existing it very likely do suffer pollution-induced toxicity. To verify this suggestion expand knowledge, necessary future combine more holistic modelling links effects. Only then will possible obtain impact protect these fragile

Chemical Mixtures and Multiple Stressors: Same but Different?

Environmental Toxicology and Chemistry, Journal Year: 2023, Volume and Issue: 42(9), P. 1915 - 1936

Ecosystems are strongly influenced by multiple anthropogenic stressors, including a wide range of chemicals and their mixtures. Studies on the effects stressors have largely focussed nonchemical whereas studies chemical mixtures ignored other stressors. However, both research areas face similar challenges require tools methods to predict joint or frameworks integrate missing. We provide an overview paradigms, tools, commonly used in stressor mixture discuss potential domains cross-fertilization challenges. First, we compare general paradigms ecotoxicology (applied) ecology explain historical divide. Subsequently, approaches for identification interactions, characterization, designing experiments. suggest that too focused interactions would benefit from integration regarding null model selection. Stressor characterization is typically more costly While comprehensive classification systems at suborganismal level been developed, recent account environmental context.
