Climate change impacts on pesticide contamination of surface runoff

2 May 2016

Impact of the adaptation measure (lowering the rainfall threshold from 1 to 0.1 mm) and of climate change on the runoff load of dissolved phosmet, assessed on the basis of the averages over 30 years for the nine sites simulated. [...] Impact of the adaptation measure (raising of the rainfall threshold from 1 to 5 mm) and of climate change on the runoff load of dissolved phosmet, assessed on the basis of the averages over 30 years for the nine sites simulated. [...] Impact of the adaptation measure (soil incorporation) and of climate change on the runoff load of dissolved atrazine, assessed on the basis of the averages over 30 years for the 10 sites simulated. [...] These two factors are heavily dependent on climate, but also on the interval between pesticide applications and rainfall, the leaf area index of plant cover, soil properties, the slope of the land and the mobility and persistence of the pesticide. [...] In fact, given that the infection period will occur earlier in the spring in the future, the temperature during the infection period remains more or less the same as in the past.
