Vegetated treatment systems have the ability to reduce the risk of adverse effects of nonpoint source pesticide pollution in agricultural surface waters, however, flow-through systems have rarely been evaluated. Peak concentrations of a mixture of two insecticides and two fungicides (Indoxacarb, Tebuconazole, Thiacloprid and Trifloxystrobin) were reduced by more than 90 % in 45 m experimental stream mesocosms. Plant density and solubility had the highest explanatory power for the response var...Vegetated treatment systems have the ability to reduce the risk of adverse effects of nonpoint source pesticide pollution in agricultural surface waters, however, flow-through systems have rarely been evaluated. Peak concentrations of a mixture of two insecticides and two fungicides (Indoxacarb, Tebuconazole, Thiacloprid and Trifloxystrobin) were reduced by more than 90 % in 45 m experimental stream mesocosms. Plant density and solubility had the highest explanatory power for the response variable reduction of peak concentration (RA(2)A = 0.70, p < 0.001). Optimized vegetated streams can be highly effective in reduction of runoff related pesticide peak concentrations. » weiterlesen» einklappen
