Sommaire de l'article

Relatively few studies are available on realistic cumulative risk assessments for dietary pesticide exposure.
Despite available studies showing low risk, public concern remains. A method to estimate realistic residue levels
based on information from spraying journals and supervised residue trials was described in a previous publication.
The present article proposes a new method to estimate average residue levels in imported foods based
on residue monitoring data and knowledge about agronomic practices. The two methods were used in combination
to estimate average pesticide residue levels in 47 commodities on the Danish market. The chronic consumer
exposure was estimated in six Danish diets. The Hazard Index (HI) method was used to assess consumer
risk. Despite the conservative (cautious) risk assessment approach, low HI values where obtained. The HI was
16% for adults and 44% for children, combining the risk of all pesticides in the diet. Conclusion: the present
study adds support to the evidence showing that adverse health effects of chronic pesticide residue exposure in
the Danish population are very unlikely. The HI for pesticides for a Danish adult was on level with that of alcohol
for a person consuming the equivalent of 1 glass of wine every seventh year.
