Oral and dermal absorption of chlorpyrifos: a human volunteer study.
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 ...
متن کاملLiver injury in workers exposed to dimethylformamide.
An apparent epidemic cluster of toxic liver disease was reexamined among workers exposed to the solvent dimethylformamide. A demographically similar but unexposed group from a preemployment population was used for comparison. Analysis, after data transformation of the liver transaminases, revealed significant differences between the two populations with respect to the serum glutamic pyruvic tra...
متن کاملDermal Absorption of Chlorpyrifos
Geer et al. (2004) provided an interesting comparison between passive dosimetry measures and biomonitoring for chlorpyrifos (CP) exposure in pesticide workers. However, they made a questionable assumption of a 3% dermal absorption factor (DAF) for CP, stating: ‘[The] study by Nolan et al. (1984), supports the use of a 3% DAF, the Environmental Protection Agency (EPA) accepted value, whereas Kri...
متن کاملDermal absorption of aromatic amines in workers with different skin lesions: a report on 4 cases
There are only few studies about the relationship of skin lesions and the percutaneous uptake of hazardous substances in exposed workers. Several aromatic amines are well known carcinogens for humans and/or animals. This case report emphasizes the relevance of dermal absorption of the aromatic amine ortho-toluidine considering four workers with different skin status (healthy, erythematous and b...
متن کاملEffect of light Polarization on the absorption index of alkali metal vapor in optical pumping phenomenon
Recently atomic magnetometers are one of the best tools in biomagnetic measurement such as magnetic field of brain and heart. In this paper, the technology of optically pumped atomic magnetometer based on circularly polarized light absorption pumping is described. We have been investigated a new method for measuring polarization effect in an alkali vapor based on polarized light transmission. I...
