Research output: Chapter in Book/Report/Conference proceedingChapter in report


In 1998, the Danish Government initiated the Pesticide Leaching Assessment Programme (PLAP), an intensive monitoring programme aimed
at evaluating the risk of pesticide leaching under field conditions. The PLAP is intended to serve as an early warning system providing decision makers with advance warning if approved pesticides leach in unacceptable concentrations. The programme focuses on pesticides used in arable
farming and monitors leaching at 5 agricultural test sites representative of Danish conditions. The objective of the PLAP is to improve the scientific foundation for decision making in the Danish registration and approval procedures for pesticides, enabling field studies to be included in risk assessment of selected pesticides. The specific aim of the programme is to analyse whether pesticides applied in accordance with current regulations leach at levels exceeding the maximum allowable concentration of 0.1 µg/l.

The Danish Government funded the first phase of the programme from 1998 to 2001, while the Ministry of the Environment and the Ministry of Food, Agriculture and Fisheries are funding a prolongation from 2002 to 2009. The work is conducted by the Geological Survey of Denmark and Greenland (GEUS), the Danish Institute of Agricultural Sciences (DIAS) and the National Environmental Research Institute (NERI) under the direction of a management group comprising members from the participating institutions as well as the Danish Environmental Protection Agency.
