Bossi, R. published the artcileAnalysis of polar pesticides in rainwater in Denmark by liquid chromatography-tandem mass spectrometry, Recommanded Product: 2,4-Dichlorobenzamide, the publication is Journal of Chromatography A (2002), 957(1), 27-36, database is CAplus and MEDLINE.
A new LC-MS-MS method for anal. of rainwater was developed and validated for 53 pesticides, degradation products of pesticides and selected nitrophenols. The method was used to monitor the concentration of pesticides in rainwater at one location near Roskilde, Denmark from Feb. 2000 to August 2000. Sampling was done in periods of up to 4 wk using a cooled wet-only sampler. H2O samples were extracted by solid-phase extraction on Oasis HLB columns. The anal. of the extracts was performed by LC-MS-MS with electrospray ionization. All samples were analyzed in neg. and in pos. ionization mode, resp. for acidic and neutral compounds All analyses were done in the selected reaction monitoring mode to obtain a better signal-to-noise ratio. The method was validated for the following parameters: recovery, detection limit, uncertainty and linearity. Atrazine, terbuthylazine, isoproturon, mechlorprop and (2-methyl-4-chlorophenoxy)acetic acid were measured at concentrations >0.100 μg/l, mainly during the period of agricultural use. Nitrophenols were measured at high concentrations all year with peaks in the cold season (Feb.-Mar.).
