| Abstract | PESTAB. A search for micropollutants confirmed the presence of traces of chlorinated and phosphorous pesticides and of phtalates in atmospheric dust samples collected in 3 districts of Southern France from 1973 through 1975. The dust traps consisted of steel plaques coated at first with vaseline and later with silicon grease and exposed at 3 m and 1.5 m from the ground for 14 days. Extracts obtained from these plaques were analyzed by gas chromatography. The least commonly found pollutants included alpha-HCH (alpha-BHC), dicofol, diazinon, fenithrotion, malathion, methyl parathion, PCB and a phtalate (DIBP). The four most frequently detected were gammaHCH (lindane), (in 95% of the observations), parathion, dibutyl phtalate (DBP) and diethylhexyl phtalate (DEHP). The frequency of gamma-HCH, more prevalent from January to August, seemed to be related to its use in agriculture. No valid correlations could be established between the fluctuations in amounts noted and meteorological factors. In 1976, a special search for hexachlorobenzene (HCB) yielded very few results. There was a total absence of residues of DDT or its metabolites. The discovery, by mass spectrometry, of the off-and-on presence of phtalates in rather high amounts for certain periods (up to 6500 mug for DEHP and 1000 mug for DBP) appeared to warrant further investigation. |
