Abstract
eng: Engelsk: Very high concentrations of phenoxyherbicides are found in soil and
groundwater under a machinery yard previosly belonging to Skelskør orchard. Downward
migration pesticide peak concentrations of 1 to 2 mg/l are occuring at 5-7 m depth. The
vertical migration rate of the pesticide front towards the aquifer at 22 m depth is 0.1 to
0.2 m/year. In the Skelskør orchard pesticide occurrence in soil and groundwater is erratic
and the concentrations of findings are very low.
Resumé
dan: Dansk: Høje koncentrationer af phenoxyherbicider er fundet i jord og grundvand under
en vaskeplads i tilknytning til Skelskør frugtplantage. Pesticider er påvist i
sum-koncentrationer på 1 mg/l til 2 mg/l i 5-7 m’s dybde. Vandringen af pesticiderne
er nedadrettet mod grundvandsreservoiret i ca. 22 m’s dybde. Vandringshastigheden er
estimeret til 0,1 til 0,2 m/år. I selve frugtplantagen er pesticidfundene spredte og med
lave koncentrationer.
