[Occupational and environmental exposure to anilide and dicarboximide pesticides].
Dicarboximide fungicides (DF) such as vinclozolin, iprodione, procymidone are widely used on vines, fruit and vegetables, and anilide herbicides (AH) such as diuron, linuron, propanil are used to control weeds on hard surfaces, such as, roads, railway tracks, paths, and in crops, forestry. Italian reports on food safety found many samples contaminated by pesticides belonging to these categories, even though only few exceeding L.M.R. Since adverse effects on human health, such as endocrine disruption, have been reported, biological monitoring is essential for exposure assessment both of occupationally exposed subjects and of the general population. Common metabolites of DF and AH are dichloroanilinines such as 3,4-DCA and 3,5-DCA, urine samples from 153 subjects living in Novafeltria, central Italy, were collected for analysis of 3,4- and 3,5-DCAs, each participant was invited to complete a very detailed questionnaire. A total of 151 out of 153 samples were found to be positive for 3,5-DCA, and 81.7% were positive for 3,4-DCA. Also 33 workers, engaged in application of propanil on rice in northern Italy, were involved in the study and 3,4-DCA was determined as marker of exposure. 3,4 and 3,5 dichloroaniline are useful and promising biological indicators for monitoring occupational and environmental exposure to these classes of pesticides.
