Abstract/Summary
|
-
Pesticides negatively affect biodiversity and ecosystem functions of surface waters. The current pesticide risk assessment is afflicted with uncertainties. This PhD thesis (i) introduces an enhanced version of the Chemcatcher® passive sampler for the quantification of pesticides in running waters, (ii) reveals the contribution of wastewater treatment plants (WWTP) to insecticide loads in running waters and the associated consequences for stream macroinvertebrates, and (iii) confirms the recolonisation process of in-stream drift hypothesised for downstream community recovery from pulsed pesticide contamination. After an introduction into the fields of pesticides, running water ecology, and pesticide monitoring in running waters, the thesis continues with three studies on pesticide exposure and effects in lotic ecosystems.^
