Aldicarb sulfoxide is a metabolite and degradation product of the carbamate pesticide aldicarb . Aldicarb sulfoxide (10 μg/ml) reduces the number of male T. semipenetrans second-stage larvae that reach the third, fourth, and adult stages of development. It inhibits carboxylesterase and cholinesterase in zebrafish (IC50 = 10 μM for both).

Effects of aldicarb and its sulfoxide and sulfone on the biology of Tylenchulus semipenetrans
J Nematol 1978 Jan;10(1):100-6.PMID:19305820doi
In laboratory testing, egg hatch of Tylenchulus semipenetrans was stimulated at concentrations of 1 and 10 microg/ml aldicarb solution and inhibited at 50 and 100 microg/ml. Aldicarb was more inhibitory to egg hatch than the Aldicarb Sulfoxide and the aldicarb sulfone. Inhibition of hatch at the high concentration was associated with delays in the molting processes, lack of larval movement within the egg, and delays in embryonic development. Nematode motility was reduced at 10, 50, and 100 microg/ml of aldicarb and Aldicarb Sulfoxide solution, and at 50 and 100 microg/ml aldicarb sulfone. Male development was retarded at 10 microg/nrl and almost completely inhibited at 50 and 100 microg/ml of the three chemicals. In greenhouse tests, female development antl reproduction on roots of citrus seedlings were suppressed by aldicarb at rates of 2.6 microg/ml and completely inhibited at 10.6 microg/ml of soil solution during a 50-day experimental period. Under field conditions, there was little systemic movement of aldicarb into roots located outside treated areas. Aldicarb reduced the nematode larvae and the female adult population in the second year after the second treatment. There were no differences in egg hatch and sex ratio of citrus nematodes between treated and nontreated roots.
Aldicarb Sulfoxide/aldicarb sulfone mixture in drinking water of rats: effects on growth and acetylcholinesterase activity
J Toxicol Environ Health 1985;16(2):163-72.PMID:4078930DOI:10.1080/15287398509530730.
A 1:1 mixture of Aldicarb Sulfoxide/aldicarb sulfone was administered to young adult Wistar rats via the drinking water at nominal concentrations of 19.2, 4.8, 1.2., 0.3, 0.075, or 0 ppm for 29 d. Blood was collected after 8, 15, and 29 d of treatment for plasma and erythrocyte cholinesterase determinations, and brain cholinesterase was determined at sacrifice. Body weight, food intake, and water consumption were measured weekly. Body weight gain and water consumption were reduced at 7, 14, 21, and 29 d in male and female rats at 19.2 ppm. Food consumption was reduced in males at 7, 14, 21, and 29 d but was reduced in females only on d 7. Both plasma and erythrocyte cholinesterase activity were reduced after 8, 15, and 29 d in male and female rats at 19.2 ppm. Males at 4.8 ppm showed reductions in plasma activity only after d 8 and in erythrocyte activity only after d 29. Female rats at 19.2 ppm also displayed depressions in brain cholinesterase activity not observed in similarly treated males. Since the only effects noted at 4.8 ppm were reductions in plasma and red blood cell cholinesterase activity in males only and at only one of three sampling periods, these two instances are not believed to be of any biological significance. The data suggest that 4.8 ppm in drinking water is a no observable ill-effect level for exposure of rats to aldicarb residues based on the parameters measured in this study.
Determination of aldicarb, Aldicarb Sulfoxide and aldicarb sulfone in some fruits and vegetables using high-performance liquid chromatography-atmospheric pressure chemical ionization mass spectrometry
J Chromatogr A 2000 Aug 4;888(1-2):113-20.PMID:10949478DOI:10.1016/s0021-9673(00)00553-7.
An analytical method for the determination of aldicarb, and its two major metabolites, Aldicarb Sulfoxide and aldicarb sulfone in fruits and vegetables is described. Briefly the method consisted of the use of a methanolic extraction, liquid-liquid extraction followed by solid-phase extraction clean-up. Afterwards, the final extract is analyzed by liquid chromatography-atmospheric pressure chemical ionization mass spectrometry (LC-APCI-MS). The specific fragment ion corresponding to [M-74]+ and the protonated molecular [M+H]+ ion were used for the unequivocal determination of aldicarb and its two major metabolites. The analytical performance of the proposed method and the results achieved were compared with those obtained using the common analytical method involving LC with post-column fluorescence detection (FL). The limits of detection varied between 0.2 and 1.3 ng but under LC-FL were slightly lower than when using LC-APCI-MS. However both methods permitted one to achieve the desired sensitivity for analyzing aldicarb and its metabolites in vegetables. The method developed in this work was applied to the trace determination of aldicarb and its metabolites in crop and orange extracts.
Determination of aldicarb, Aldicarb Sulfoxide and aldicarb sulfone in tobacco using high-performance liquid chromatography with dual post-column reaction and fluorescence detection
J Chromatogr A 1994 Apr 1;664(2):289-94.PMID:8199709DOI:10.1016/0021-9673(94)87019-5.
A screening method for the determination of aldicarb (AS) and its sulfoxide (ASX) and sulfone (ASN) metabolites in tobacco at low ppm levels is described. Tobacco samples are extracted using methanol with the aid of sonication at ambient conditions. The extract is filtered and then injected into a high-performance liquid chromatograph equipped with a dual post-column reaction system and a fluorescence detector. Chromatographic separation is performed on a C18 column with a mixture of methanol-acetonitrile-water containing 0.1% of triethanolamine as the mobile phase. Triethanolamine is added to improve peak shape of AS residues and to reduce the undesired interaction between residual silanols and interferences, mainly amino acids and other amines. The average recoveries for AS residues spiked in tobacco are higher than 95% for AS, 91% for ASN and 85% for ASX at levels of 0.5-10 ppm (w/w). The detection limit is 0.5 ppm for each of the target compounds.
Kinetics of aqueous base and acid hydrolysis of aldicarb, Aldicarb Sulfoxide and aldicarb sulfone
J Environ Sci Health B 1983;18(2):189-206.PMID:6853962DOI:10.1080/03601238309372363.
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. Second order rate constants were calculated, and it was found that aldicarb sulfone is more sensitive to hydroxide ion concentration than Aldicarb Sulfoxide which is more sensitive than aldicarb. Temperature effects were determined by measuring the base hydrolysis rate constant for aldicarb sulfone at 5, 15, 20, 25, 30, and 35 degrees C. An activation energy of 15.2 +/- 0.1 kcal/mole was calculated. Addition of a neutral electrolyte decreased the rate constant for base hydrolysis. Acid catalyzed hydrolysis rate constants were also measured for aldicarb sulfone, and, as expected, the reaction was much slower. The second order (reaction) rate constant for base hydrolysis of aldicarb sulfone is 40.3 (+/- 0.5) liter mole-1min-1; for acid catalyzed hydrolysis it is 7.33 (+/- 0.06) X 10(-4) liter mole-1min-1.
