Kinetics of aqueous base and acid hydrolysis of aldicarb, aldicarb sulfoxide and aldicarb sulfone
Journal of Environmental Science and Health, Part B, 1983The kinetics of degradation of aqueous solutions of aldicarb, aldicarb sulfoxide and aldicarb sul fone by base hydrolysis were investigated. Pseudo first order rate constants of 37 micrograms/l solutions were determined at different hydroxide concentrations by acid-base titration.

Chromatographia, 1987
Aldicarb, aldicarb sulfoxide, and aldicarb sulfone were chromatographed on an octyl-silica bonded-phase column and on an unmodified silica column using acetonitrile/water mobile phases. The elution order of the analytes from the silica column was different from that using the octyl-silica bonded phase and allowed confirmation of residues of aldicarb ...

Degradation of aldicarb, aldicarb sulfoxide, and aldicarb sulfone in chlorinated water
Environmental Science & Technology, 1991The three insecticidal species of Temik, aldicarb (I), aldicarb sulfoxide (II), and aldicarb sulfone (III), degrade rapidly in chlorinated water. I is sulfoxidized to II, while II forms III, (chloromethyl)sulfonyl species, and N-chloro-II. III forms N-chloro-III, which decomposes to III acid and dichloromethylamine.

Journal of Chromatography A, 1982
Abstract A method was developed for the residue analysis of aldicarb, its toxic metabolites (aldicarb sulfoxide and aldicarb sulfone), carbofuran and its metabolites (3-hydroxy- and 3-ketocarbofuran) in water. The procedure involved extracting with methylene chloride, initial separation and clean-up with a Sep-PakTM silica cartridge, followed by high-

Aldicarb Contamination of Groundwater
1988Aldicarb, [2-methyl-2-(methylthio)propionaldehyde O-(methylcarbamoy1)-oxime], the active ingredient in TEMIK® insecticide/nematicide, was discovered in 1962 (Weiden et al. 1965) and is currently registered in over 60 countries for a large number of crops.

Abstract A magnetic particle based solid-phase enzyme linked immunosorbent assay (ELISA) for the determination of parts per billion levels of aldicarb and its sulfoxide and sulfone metabolites in water was developed. Sensitivity is estimated at 250 ppt based on a 90% B/Bo with results available in less than one hour. Photometric analysis of the final

Transformation of aldicarb sulfoxide and aldicarb sulfone in four water‐saturated sandy subsoils
Pesticide Science, 1995AbstractThe transformation of aldicarb sulfoxide and aldicarb sulfone was studied in incubations with water‐saturated subsoils under simulated field conditions at 10°C. The subsoils were collected at four locations from beneath the water table at a depth of 2.5 to 3.5 m.
