This study presents a novel pesticide transport module for the OpenLISEM runoff and erosion model. During water events, high amounts of pesticides can be transported alongside runoff. Simulating this process helps to mitigate adverse effects in environment. We conceptualized uptake during with mixing-layer, including mass transfer dissolved into detachment combination enrichment sorbed pesticides.

A sensitivity analysis showed that was mainly influenced by rate, soil-water partitioning exponent ratio. accurate simulation OpenLISEM, enables OLP simulate redistribution adequately.

ABSTRACT Fungal communities are critical for leaf decomposition, a central ecosystem function in streams. A wide range of anthropogenic stressors can alter their structure and (i.e., decomposition). Additionally, fungal subject to seasonal turnover due natural processes. Despite this, seasonality interaction with varying stressor exposure has rarely been studied the context decomposition. We investigated community composition decomposition over one agricultural growing season by deploying bags at least impacted forest viticultural sites 10 we transplanted that had colonised investigate how changes affect communities. Leaf was repeatedly lower treatment than treatment, which partly explained environmental variables. The leaves varied across time points overall more similar treatment. April were treatments, whereas all exhibited different turnover. At later (June, August September), from transplant remained similar, likely triggered priority effects location colonisation (forest). however, deviated these points, coincided timing fungicide application. Overall, show both exhibit stressor‐related variability. Thus, our study demonstrates actual regime need be considered well described when investigating land use on associated

A comprehensive assessment of pesticide transport in surface waters is challenging due to discharge characteristics and the occurrence transformation products (TPs). Detailed long-term sampling concentrations, including rainfall application events, still lacking better predict pathways toxicity within agricultural catchments. In present study, TP dynamics were evaluated over a three-year monitoring period, which included 12 stormwater events 7 dry events. An extensive target screening for 328 pesticides was conducted, while simultaneously performing suspect nontarget analysis (SNTA) using liquid chromatography high-resolution mass spectrometry. Twenty-one two TPs associated with main crop, rice, identified as major pollutants. The risk results, based on stepwise data collection, suggested that insecticides, primarily neonicotinoids, exhibited severe ecological risk. Additionally, SNTA revealed presence 8 parent compounds 46 TPs. occurred following peak periods, indicating integrated practical approach assessment. precautionary identification suggests potential aquatic effects may be underestimated by conventional strategy.

Abstract Exposure to pesticides may cause adaptation not only in agricultural pests and pathogens, but also non-target organisms. Previous studies mainly searched for adaptations organisms pesticide-polluted sites. However, propagate heritable pesticide effects, such as increased tolerance, non-exposed populations through gene flow. We examined the tolerance—as one of pre-assumptions local adaptation—of freshwater crustacean Gammarus spp. (at genus level reflecting gammarid community). The tolerance was quantified acute toxicity tests using insecticide imidacloprid.

Furthermore, we population genetic structure fossarum energy reserves (here lipid content) G. well three site types (i.e. agriculture, edge refuge). found significantly lower imidacloprid from compared refuge sites, potentially due higher environmental stress indicated by a slightly content per mg tissue. no differences between populations, indicating propagation effects edges. among showed significant differentiation streams, within stream across types. suggest that high flow each hindered resulted similar (pre)adaptations levels types, although they exhibited different pollution. Further on target genes (e.g., conferring tolerance), fitness phenotypes particular are required adjacent pristine ecosystems detect potential propagations effects.

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 area (0.015 km 2 ) within 4–30 days. Reoccurrence was observed ~ 18% 76% compounds, 40% priori considered chronically expose aquatic ecosystems. calculated probability reoccurrence (POR) medium-term (4–7 long-term (8–30 360 pesticides. Relative PORs (ratio between POR) revealed three occurrence patterns: ephemeral, intermittent permanent. While fungicides dominated intermittently occurring substances, aligning with application strategies physico-chemical properties, neonicotinoids legacy among substances permanently occurring. The results this study shed new light on previously underestimated longer-term many environments (35% or pollute environment chronically), entailing challenges chronic risk assessments evaluation effects biodiversity.
