Environmental Concentrations of Active Substances of Plant Protection Products and their Metabolites in Groundwater (PECgw) in the National Assessment for Authorisation in Germany
In the national assessment for authorisation in Germany the leaching behaviour of a plant protection product is determined in a stepwise procedure in accordance with FOCUS groundwater report (2009). The recommendations given in this paper here are related to tier 1 and tier 2, only.
