Comparison of measurement of dialkyl phosphates in milk/urine and blood cholinesterase and insecticide concentrations in goats exposed to the organophosphate insecticide, imidan

Comparison of measurement of dialkyl phosphates in milk/urine and blood cholinesterase and insecticide concentrations in goats exposed to the organophosphate insecticide, imidan. Mount, Michael E. (Sch. Vet. Med., Univ. California, Davis, CA, USA). Toxicol. Appl. Pharmacol., 72(2), 236-44 (English) 1984. CODEN: TXAPA9. ISSN: 0041-008X. DOCUMENT TYPE: Journal CA Section: 4 (Toxicology) Recognition of exposure to imidan (I) [732-11-6] was assessed in goats by dialkyl phosphate concns., blood cholinesterase (ChE) [9001-08-5] detns., and blood I concns. Groups of 3 goats received 5.0 mg I/kg/day (low dose) or 10 mg I/kg/day (high dose) for 7 days orally. One goat received no I and 1 goat received an acute single dose (200 mg/kg). The urine of all treated goats was examd. for the excretory dialkyl phosphates, O,O-dimethyl phosphorodithioate (DMDTP) [756-80-9] and O,O-dimethyl phosphorothionate [1112-38-5]. The overall mean DMDTP urinary concn. was 19.1 ppm (10 mg/kg treatment group) and 7.2 ppm (5 mg/kg treatment group). These metabolites rapidly disappeared following removal of the treatment except in those goats clin. affected. Milk contained no identifiable concns. of dialkyl phosphates. ChE depression was obsd. in all I-treated goats, and a dose effect was obsd. 9001-08-5 and 732-11-6 which are cas registry numbers of substances are two of reagents here. No I was detected in whole blood of either the 5 or 10 mg/kg treatment groups. Low blood concns. (ppb) of I were measured in the acute single-dose exposed goat. Both urinary DMDTP and blood ChE provided recognition of I exposure. DMDTP, however, was immediately present in urine after exposure and provided stronger support for organophosphate exposure than did blood ChE. .

DOCUMENT TYPE: Journal CA Section: 68 (Phase Equilibriums, Chemical Equilibriums, and Solutions) The 2-phase stability consts. of metal complexes MAn [M7+ = Ni(II), Zn(II), Cd(II), Pb(II), Tl(I), In(III)] with a series of O,O-dialkyldithiophosphoric acids in the system water-org. solvent) were detd. By use of correlation anal., the role of the steric and hydrophobic effects of the substituents at the P atom on the stability const. bn and distribution const. P of the complexes was elucidated. The data obtained are of use for detg. the relationships in the influence of structure of a reagent on its extn. 756-80-9 and 2253-52-3 are just another two chemicals used in this study. properties and on the conditions for practical application of O,O-dialkyldithiophosphoric acids for metal extn. .
