Monitoring of pesticide leaching from cultivated fields in Denmark

摘要

The Danish Pesticide Leaching Assessment Programme(PLAP) was initiated in 1998 by the Danish Parliamentin order to evaluate whether the use of approved pesticideswill result in an unacceptable contamination of the groundwater, if applied under field conditions in accordance withcurrent Danish regulation. In this programme, water samples from variably saturated soil and groundwater collectedat five cultivated fields are analysed for selected pesticidesand their degradation products. The PLAP results are summarised and evaluated in yearly reports and used by theDanish Environmental Protection Agency in the regulation of pesticides in Denmark (Brüsch et al. 2015). In orderto represent typical farming scenarios in Denmark, the testfields are situated on meltwater and marine sands, and ontile-drained clayey soils in till areas.
