Abstract
eng: The report describes that volatility of pesticides can be determined by a laboratory
model system if based on a standardised method, which is carefully described. The local
atmospheric transport model shows that dry deposition near sprayed fields can be
potentially as important as spray drift. When precipitation was collected and analysed for
selected pesticides they show concentrations like the rest of Europe, with highest
concentrations in the spraying season. The effect of these concentrations of one single
herbicide (mecoprop) was determined on a number of sensitive test plants with only limited
effects.
Resumé
dan: Rapporten belyser, at fordampningen af pesticider kan måles i modelforsøg i
laboratoriet ved omhyggelig beskrivelse af metoden. Modeller til beskrivelse af lokal
atmosfærisk spredning af pesticider viser, at tør deposition kan være lige så vigtig
som vinddrift. Analyser af pesticider i nedbør følger de samme koncentrationer som i
andre europæiske lande, med de højeste fund i sprøjtesæsonen, og der er ikke
konstateret effekter af de deponerede pesticider på planter.
