Methods for the determination of agrochemicals in tobacco and tobacco products

Methods for the determination of agrochemicals in tobacco and tobacco products. Part IV. A determination method for vamidothion and its metabolites. Sagredos, A. N.; Moser, R. (NATEC/Ges. Naturwissenschaftl.-Tech. Dienste m.b.H., Hamburg, Ger.). Beitr. Tabakforsch., 9(2), 111-15 (German) 1977. CODEN: BETAAY. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemicals) Vamidothion [2275-23-2], and its metabolites vamidothion sulfone [20300-00-9] and vamidothion sulfoxide [20300-00-9] were detd. in tobacco by extn. with Me2CO-AcOH-H2O mixt., followed by cleanup on a Al2O3 column, and gas chromatog. using OV-17 and QF 1 on Gaschrom Q. N was the carrier gas. Detection was by a S flame-photometer. The column temp. was 175.degree. for vamidothion, 135.degree. foro the sulfoxide, and 170.degree. for the sulfone. The detection threshold was 0.1 ppm. Fortification at the 0.5 ppm level led to 92% recovery for vamidothion, 70% for the sulfoxide, and 91% for the sulfone.

Toxicological effects of several organophosphate insecticides on the mulberry plant louse and the silkworm

Toxicological effects of several organophosphate insecticides on the mulberry plant louse and the silkworm. Hsieh, F. K.; Chen, S.; Kao, S. S. (Div. Entomol., Plant Prot. Cent., Taiwan). T'ai-wan Nung Yeh Chi K'an, 12(2), 120-8 (Chinese) 1976. CODEN: TNYCAK. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemicals) Of the 9 organophosphates tested, Elsan [2597-03-7], Fenthion [55-38-9], Kilval [2275-23-2], naled [300-76-5], and Nexion [2104-96-3] exhibited the most toxic activity against the prime pest of the mulberry plant, Paurocephala psylloptera, in Taiwan. At the same time, Elsan, Fenthion, Kilval, naled, and Nexion were found to have relatively low toxicity and quick receding residual effects on the silkworm.
