New EU research on pesticide effects in water
An EU-funded research project has developed a system that could provide an accurate and cost-effective means of assessing the effects of pesticides in streams, says the European Commission's Environment Directorate General. The Species at Risk (SPEAR) system could help implement the EU water framework Directive (2000/60), which sets quality standards for European water sources ( Agrow No 546, p 11). The original SPEAR system was modified so that it assessed pesticide impacts on groups of related freshwater invertebrate species, rather than on individual species. This made assessments more cost-effective. In addition, tests on monitoring data from Finland, France and Germany indicated that toxicity values were not influenced by a region and could be used throughout Europe. The study was published in the journal, Environmental Pollution.
