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.

Aldicarb toxicosis in a dairy herd
Journal of the American Veterinary Medical Association, 1991Aldicarb, an extremely toxic carbamate, caused sudden death of several lactating Holstein cows. Confirmation of this toxic agent as the cause of death was hindered by its rapid breakdown in biological tissue. Therefore, aldicarb was not detected in rumen contents of some of the dead cows, and brain acetylcholinesterase values were essentially normal ...

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.

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-

Conversion rates of aldicarb and its oxidation products in soils. II. Aldicarb sulphoxide
Pesticide Science, 1978AbstractThe loss of aldicarb sulphoxide was studied in incubation experiments with soil from four plough layers and two deeper layers. The loss during the 111 days of the experiment could be described by first‐order kinetics. The half‐lives at 15°C ranged from 20 days in a clay loam to 46 days in a peaty sand.

Conversion rates of aldicarb and its oxidation products in soils. III. Aldicarb
Pesticide Science, 1978AbstractAldicarb was incubated in seven soils at 15°C and its loss was well described by first‐order kinetics. Rate constants varied between 0.078 day−1 in a peaty sand to 0.35 day−1 in a clay loam. The concentration‐time relationships for aldicarb, its sulphoxide and its sulphone were approximated by a computation model which was used to analyse the ...

Journal - Association of Official Analytical Chemists, 1981
An ion-suppression reverse phase high pressure liquid chromatographic method is described for the determination of aldicarb, aldicarb sulfoxide, and aldicarb sulfone in potatoes. Samples are extracted with methylene chloride and Na2SO4, evaporated to dryness, and cleaned up using Sep-Pak silica and Sep-Pak-C18 cartridges.

Residues of aldicarb in coconut
Pesticide Science, 1983AbstractDeterminations were made of aldicarb residues in coconut cultivated on soils containing aldicarb granules. The quantitative estimations in coconut milk and kernel were made by colorimetry and gas‐liquid chromatography; samples harvested at various times were analysed.

Aldicarb (Sulfoxide and Sulfone)
1988Aldicarb (2-methyl-2-(methylthio) propanal O-[(methylamino) carbonyl] oxime) with the trade name Temik®, is an insecticide, nematicide, and acaricide. Estimated aldicarb production was 3.0 to 4.7 million lb (1.4 to 2.1 million kg)/yr during 1979 to 1981. It is applied both to the soil and directly to plants.
