Mixed pesticide sources identified by using wastewater tracers in rivers of South African agricultural catchments.

The agriculturally dominated region of the Western Cape, South Africa is vulnerable to pesticide pollution. A 2017-2019 pesticide monitoring campaign in the agricultural catchments of Grabouw, Piketberg and Hex River Valley identified year-round detections despite few agricultural applications, making pesticide pollution sources unclear. To better trace pesticide sources in these catchments, our study measured 19 pharmaceutical compounds and one industrial chemical as an indicator for wastewater treatment plant (WWTP) effluent - in addition to 44 pesticides.

Mitigating glyphosate levels in surface waters: Long-term assessment in an agricultural catchment in Belgium.

The increasing concern over pesticide pollution in water bodies underscores the need for effective mitigation strategies to support the transition towards sustainable agriculture. This study assesses the effectiveness of landscape mitigation strategies, specifically vegetative buffer strips, in reducing glyphosate loads at the catchment scale under realistic conditions. Conducted over six years (2014-2019) in a small agricultural region in Belgium, our research involved the analysis of 732 water samples from two monitoring stations, differentiated by baseflow and event-driven sampling, and before (baseline) and after the implementation of mitigation measures.
