Since pesticides have the potential for contaminating the air by diffe
rent mechanisms of atmospheric input, pesticide residues can be detect
ed in precipitation. Examples for s-triazine concentrations in rainwat
er taken from literature were compiled and evaluated. Seasonal trends
were observed, with highest concentrations between April and June duri
ng the time of the application of s-triazine herbicides. In relation t
o the s-triazine input by agriculture, the atmospheric deposition is v
ery low. Therefore, in agricultural regions the atmospheric input of s
-triazine is not important; for unpolluted sites, however, atmospheric
input is the only source of contamination. (C) 1997 Elsevier Science
