A. Sanusi et al., Comparison of atmospheric pesticide concentrations measured at three sampling sites: local, regional and long-range transport, SCI TOTAL E, 263(1-3), 2000, pp. 263-277
We present the comparison of atmospheric concentrations of eleven currently
used pesticides (HCB, alpha -HCH, gamma -HCH, trifluraline, mecoprop, phos
alone, atrazine, carbofuran, carbaryl, diuron and isoproturon) measured in
remote (Aubure), rural (Colmar) and urban (Strasbourg) areas of Alsace and
Vosges regions (east France). Pesticides samples were collected simultaneou
sly on two of the three sites during the summer season of 1993 and 1994, us
ing a Hi-Vol sampler with Whatman filter paper and XAD-2 resin. The particl
e and gas phases were collected separately during 24 h. The relative import
ance of local emissions and local, regional and long distance transport on
the contamination of the atmosphere in the three environments (remote, rura
l and urban) were investigated. To facilitate the interpretation of the res
ults, the alpha/gamma -HCH ratio was used as a tracer of pesticide emission
