Regulation of diffuse pesticide pollution: Combining point source reduction and mitigation in stormwater wetland (Rouffach, France)

Herbicide-related signaling in plants reveals novel insights for herbicide use strategies, environmental risk assessment and global change assessment challenges

“…In this framework, introduction of novel chemical entities is considered of concern at the global level whenever these chemicals show persistence, mobility across scales, and potential impacts on Earth system processes (Steffen et al, 2015). This could potentially be the case for herbicides and their derivatives, which can be persistent in environmental compartments and the cause of widespread diffuse pollution (Arias-Estévez et al, 2008;Destandau et al, 2013). However, identification of chemicals or mixtures of chemicals that pose a real threat to a vital Earth system process is hampered by the possibility of cryptic effects where disruption may not be discovered until it occurs on a planetary scale (MacLeod et al, 2014;Persson et al, 2013).…”

Fungicides: An Overlooked Pesticide Class?

“…Several technologies can mitigate pesticide input into aquatic systems via spray drift and runoff. 66 Besides reducing the amount of applied fungicides, 67 increasing the distance from surface water bodies to sprayed agricultural fields is among the most efficient mitigation measures for reducing pesticide transport to surface waters. 66 The efficiency of nonsprayed buffer strips might be further increased by dense vegetation shielding surface water bodies from spray drift.…”

“…4 Buffer strips can also mitigate runoff from agricultural fields. 67 A field study in Denmark indicated that the width of buffer strips was critical to predicting in-stream pesticide concentrations, 69 which was likely driven by an infiltration of pesticide-contaminated water and sedimentation of pesticide-loaded soil particles. 70 Along these lines, several studies reported erosion rills (i.e., preferential flow paths) to substantially reduce the mitigation potential of vegetated buffer strips for pesticide entry via runoff.…”

Temporal and spatial variations of organochlorine pesticides in the suspended particulate matter from Lake Chaohu, China

“…Many studies showed that the natural and constructed wetlands play a very important role in pesticide reduction (e.g. Syversen and Bechmann, 2004;Rasmussen et al, 2011;Elsaesser et al, 2011;Wan et al, 2013;Tournebize et al, 2013;Krone-Davis et al, 2013;Destandau et al, 2013).…”
