A preliminary investigation was conducted on the occurrence of particular pesticides in the soil. The aim was to gain insight into the appearance and behaviour of pesticides in soil from the plough layer in order to support the admission policy. Seven pesticides were chosen for determination on the basis of their accumulation properties and their market share. Four pesticides were found in the plough layer: atrazine, fenpropimorph, parathion and simazine. The amounts measured did hardly exceed the detection limit, with the exception of atrazine which showed relatively high levels for a number of plots, but also a decline in time. Paraquat, pencycuron and pirimicarb could not be detected in any of the plots. The measured amounts correspond reasonably well with the amounts calculated with the simulation model PESTLA.
