Abstract
Nitrophenols have been determined in rain collected in Hannover (F. R. Germany) over a period of 9 months in 1988 and in snow collected in Northrhine-Westphalia (F. R. Germany) in February and March 1988. The precipitation samples were analyzed by gas chromatography using an electron capture detector a nitrogen sensitive detector and a chemiluminescence detector and by combined gas chromatography/mass spectrometry using both electron impact and negative ion chemical ionization and in addition by high performance liquid chromatography using a photodiode array detector. 2-Nitrophenol. 4-nitrophenol, 2 3-methyl-4-nitrophenol. 2.6-dimethyl-4-nitrophenol, 4-dinitrophenol (DNP), 2,4-dinitro-6-methylphenol (DNOC), 2.4-dinitro-6-sec-butylphenol (Dinoseb), one additional methylnitrophenol- and two additional dimethylnitrophenols have been identified, several other compounds have been identified tentatively. In most instances 4-nitrophenol is the predominant component observed in concentrations ranging from 0.5-17.1 myg/l in rain and from smaller than 0.5-16.1 myg/l in snow.
