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. Lateral is modelled kinematic wave based on overland flow water. The model simulations were line observations two events small agricultural catchment South-Limburg, Netherlands. A sensitivity analysis showed that was mainly influenced by rate, soil-water partitioning exponent ratio. accurate simulation OpenLISEM, enables OpenLISEM-pesticide simulate redistribution adequately.

Abstract The present work aimed to predict the fate of two pesticides, copper (Cu) and glyphosate in a Mediterranean basin with an intermittent river assess ecotoxicological risk related their presence water bodies coupling field measurements streamflow pesticide concentrations, eco-hydrological model. Soil Water Assessment Tool (SWAT) model was calibrated and, subsequently used predicted environmental concentrations pesticides surface waters. Cu assessed at reach scale by using Toxicity Exposure Ratio approach (TER). Measurements (< 0.5 μg l −1 ) exceeded maximum European threshold quality standards for (EQS) 0.1 . High were wet season September, when is mostly vineyards olive grove productions. Acute (TER < 100) associated detected several reaches. 6.5 ), mainly as fungicide vineyards, results assessment revealed that November January critical months during which most reaches showed chronic Cu.

Atrazine (ATZ), a widely used herbicide with potent endocrine-disrupting properties, has been implicated in hormonal disturbances and fertility issues. Sertoli cells (SCs) play crucial role providing mechanical nutritional support of spermatogenesis. Herein, we aimed to study the effects environmentally relevant ATZ concentrations on spermatogenesis provided by SCs. For that, mouse SCs (TM4) were exposed increasing (in μg/L: 0.3, 3, 30, 300, or 3000). After 24 h, cellular proliferation metabolic activity assessed.

Pesticides are detected in surface water and groundwater, endangering the environment. In lowland regions with subsurface drainage systems, drained depressions become hotspots for transport of pesticides their transformation products (TPs). This study focuses on detailed modelling degradation different physico-chemical properties. The objective is to analyse complex hydrological processes, understand temporal spatial dynamics pesticides. ecohydrological model SWAT+ simulates processes as well agricultural management pesticide can therefore be used develop loss reduction strategies. three (pendimethalin, diflufenican, flufenacet), two TPs, flufenacet-oxalic acid (FOA) flufenacet sulfonic (FESA). area a 100-hectare farmland northern German lowlands Schleswig-Holstein that characterised by an extensive network 6.3 km managed according common conventional practice. modelled streamflow very good agreement between observed simulated data during calibration validation.

However, it has weaknesses accounting substances, which lead underestimation subsequent delivery after precipitation events thus underestimates total load.

ABSTRACT Catchment water quality models are common tools for assessing hydrochemical processes in catchments. They improve the process understanding and help to identify pollutant sources. However, spatial temporal resolution of many is too coarse represent occurring within minutes or hours, making them unsuitable use fast‐responding Examples such cases headwater catchments influenced by urban agglomerations. ZIN‐AgriTra a physically based model that allows simulations with fine (< 1 h) 100 m) resolution. As it also implementation point sources, suitable simulation mixed land use. In this study, we test first time ability nitrogen transport transformation source catchment. High series wastewater treatment plant (WWTP) effluent quantities were available as input model. For combined sewer overflow (CSO) discharges, only discharge times measured. knowledge was still valuable during calibration improved CSO contributions events. Our setup modelling strategy allowed us simulate nitrate ammonium export from catchment sufficiently. Overall, sources have significant impact sensitivity parameters influencing mixing ratio between stream discharge. found large on quantity, not considering would inevitably lead incorrect parameterisation parameters. Models should become more inclusive order be able catchments, especially places, where data availability limited.

Advanced oxidation processes (AOPs) based on activated persulfate (PS) are gradually being employed in the treatment of novel pollutants. In this study, an efficient and reliable CoNiFe-layered double hydroxide (LDH) was prepared by a hydrothermal method, which could effectively activate peroxomonosulfate (PMS) cause free sulfate radical (SO4•−) to decompose atrazine (ATZ). The degradation rate ATZ greater than 99% within 60 min at pH 7 when initial concentration 10 mg·L−1, dosages PMS activator were 0.6 mM 80 mg·L−1. analysis confirmed reusability its strong structural stability. generation four radicals analyzed confirmed, influence reaction SO4•− > O2•− 1O2 •OH. analytical results showed that metal ions reacted with HSO5− oxidation–reduction cycle change valence state generated primary factor affecting reaction—SO4•−. Nine intermediates reduced toxicity detected possible pathways deduced, thus confirming activation mechanism CoNiFe-LDH.
