From 1995 to 1998 the concentrations of 4-nitrophenol, 2-methyl-4-nitrophenol, 3-methyl-4-nitrophenol, dinitro-ortho-cresol (DNOC) and 2,4-di-nitrophenol were measured monthly by HPLC in precipitation at eight different locations in Bavaria (Germany). Samples were collected by purpose-constructed computerised rainwater samplers which record electronically various sensor data each hour and adjust the sample temperature to 4°C. The highest nitrophenol (NP) concentrations were measured for 4-NP. The median at all locations is higher than 1 _6;g/l. The median of the other NPs ranges between 0.2 and 0.8 _6;g/l. Considering the rain amounts the highest depositions were calculated for the regions Spessart, Bayerischer Wald and Chiemgauer Alpen. The median of 4-NP depositions extents to 200 _6;g/(month m²). The highest medians of the other NP depositions reach approximately 50 _6;g/(month m²).
