Pesticides in air and in precipitation and effects on plant communities


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.
