Kinetics of aqueous base and acid hydrolysis of aldicarb, aldicarb sulfoxide and aldicarb sulfone

Journal of Environmental Science and Health - Part B Pesticides, Food Contaminants, and Agricultural Wastes, 1983
The 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.

Hydrolysis studies of aldicarb, Aldicarb sulfoxide and aldicarb sulfone

Environmental Toxicology and Chemistry, 1983
Abstract Hydrolysis studies were conducted on aldicarb, aldicarb sulfoxide and aldicarb sulfone for 186 to 228 d. These long-term studies show that, for a given temperature, the reaction rate constants for the three compounds are relatively constant below pH 7 and increase rapidly as the pH increases beyond 7.

Aldicarb poisoning

Human & Experimental Toxicology, 2000
Aldicarb (2 ethyl-2 (methylthio) propanal o-[(methlamino)-carbonyl] oxime) is a pesticide manufactured since 1965. This carbamate ester is sold under the tradename, Temiks, and is used as insecticide and nematicide. The Environmental Protection Agency has classified aldicarb in the highest toxicity category and has defined a strict control for its ...

Toxicology of Aldicarb

1988
Aldicarb (2-methyl-2[methylthio]propionaldehyde 0-[methyl carbamoyl]-oxime; TEMIK®, Rhone-Poilenc’s registered trademark) effectively controls a wide variety of insects, mites, and nematodes and is used worldwide on more than 40 economically important crops.

Degradation of aldicarb, aldicarb sulfoxide, and aldicarb sulfone in chlorinated water

Environmental Science & Technology, 1991
The 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.

Separation of aldicarb, aldicarb sulfoxide, and aldicarb sulfone on unmodified silica with reverse-phase eluents

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 ...

Development and evaluation of a magnetic particle based enzyme immunoassay for aldicarb, aldicarb sulfone and aldicarb sulfoxide

Chemosphere, 1992
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
