- Effects of pesticides on community structure and ecosystem functions in agricultural streams of three biogeographical regions in EuropeRalf Bernhard Schäfer
UFZ Helmholtz Centre for Environmental Research, Dept System Ecotoxicology, Permoser Strasse 15, 04318 Leipzig, Germany
Sci Total Environ 382:272-85. 2007..Our findings demonstrate that pesticides may influence the structure and function of lotic ecosystems and that the SPEAR approach can be used as a powerful tool in biomonitoring over large spatial scales...
- Determination of 10 particle-associated multiclass polar and semi-polar pesticides from small streams using accelerated solvent extractionRalf Bernhard Schäfer
UFZ Helmholtz Centre for Environmental Research, Department of System Ecotoxicology, Permoser Strasse 15, 04318 Leipzig, Germany
Chemosphere 70:1952-60. 2008..We suggest that the method presented here be used for the extraction and quantitation of particle-associated polar pesticides...
- Performance of the Chemcatcher passive sampler when used to monitor 10 polar and semi-polar pesticides in 16 Central European streams, and comparison with two other sampling methodsRalf Bernhard Schäfer
Department of System Ecotoxicology, UFZ Helmholtz Centre for Environmental Research, Permoserstrasse 15, 04318 Leipzig, Germany
Water Res 42:2707-17. 2008..We conclude that the Chemcatcher is suitable for the monitoring of polar organic toxicants and presents an alternative to conventional spot sampling in the monitoring of episodically occurring pollutants...
