The data in this article are related to the research entitled, "Assessment of 1H NMR-based metabolomics analysis for normalization of urinary metals against creatinine" (M. Cassiède, S. Nair, M. Dueck, J. Mino, R. McKay, P. Mercier, B. Quémerais, P. Lacy, 2016) [1]. This article describes the analysis of urinary metabolites in normal, healthy individuals by 1H NMR-based metabolomics. NMR spectr...

OBJECTIVES To determine the kinetics of elimination of urinary dialkylphosphate metabolites after oral and dermally applied doses of the organophosphate pesticide chlorpyrifos to human volunteers and to determine whether these doses affected plasma and erythrocyte cholinesterase activity. METHOD Five volunteers ingested 1 mg (2852 nmol) of chlorpyrifos. Blood samples were taken over 24 hours ...

This laboratory has previously shown that, when animals are injected with microgram amounts of high specific activity C4-histamine, at least three radioactive metabolic products can be demonstrated in the urine. Paper chromatograms of the urine in butanol80, ethanol 10, and ammonia 30 showed three radioactive peaks. The following information regarding their identity has been published. Peak 1 i...
