“…Aldicarb oxime and aldicarb nitrile are found to be the major byproducts of aldicarb formed in spiked anaerobic water samples. Methods which have been reported for the analysis of aldicarb include thin-layer chromatography (TLC) (2,3), liquid chromatography (LC) with various detectors (mass spectrometer (4), ultraviolet detector (5), arid postcolumn derivitization and fluorometric detection (6, 7)), and gas chromatography (GC) with various detectors (Hall detector (8), mass spectrometer (GC/MS) (9), flame ionization detector (2), and esterification and detection with an electron capture detector (10)). Only the LC and TLC methods avoid degra-dation of aldicarb.…”

A technique for the analysis of aldicarb and two of Its degradation products Is described. The use of a short capillary column coupled to a mass spectrometer Is found to facilitate the analysis of the thermally labile carbamate pesticide. Methane and Isobutane chemical Ionization reagent gases are evaluated. The limits of detection for aldicarb, aldicarb oxime, and aldicarb nitrile are 0.3 ng, 1.2 ng, and 0.15 ng, respectively. Application of the technique to the study of the fate of aldicarb In anaerobic groundwaters Is described. Aldicarb Is found to slowly hydrolyze to aldicarb oxime In sterile anaerobic groundwater at pH 8.2; In the presence of a high concentration of anaerobic microorganisms, however, aldicarb rapidly degrades to aldicarb nitrile.

“…Other derivatizing reagents than heptafluorobutyric anhydride were considered as possibilities for the detection of Matacil residues. These reagents included benzenesulfonyl chlorides (Moye, 1975), trichloroacetyl chloride (Stanley et al, 1972), and l-fluoro-2,4-dinitrobenzene (Holden, 1973). The derivatives formed with the first two were found to be unsuitable for Matacil whereas the 2,4dinitrophenyl ether derivative formed with l-fluoro-2,4dinitrobenzene was found to be suitable.…”

“…RESULTS AND DISCUSSION. Moye (1975) developed a residue procedure for carbaryl and carbofuran which involved hydrolysis of the carbamate pesticides to their corresponding phenols and derivatization of the phenols with 2,5-dichlorobenzenesulfonyl chloride. Although electron-capture detection was used, Moye (1975) noted that 10 ng of 1-naphthyl 2,5-dichlorobenzenesulfonate responded well to a flame photometric detector operating in the sulfur mode.…”
