Sex differences in urinary levels of several biological indicators of exposure: a human volunteer study.
The aim of the study was to quantify the variability on biological indicators of exposure between men and women for three well known solvents: methyl ethyl ketone, 1-methoxy-2-propanol and 1,1,1-trichloroethane. Another purpose was to explore the effect of selected CYP2E1 polymorphisms on the toxicokinetic profile. Controlled human exposures were carried out in a 12 m³ exposure chamber for each...
متن کاملEffect of age on toxicokinetics among human volunteers exposed to propylene glycol methyl ether (PGME).
UNLABELLED Aging adults represent the fastest growing population segment in many countries. Physiological and metabolic changes in the aging process may alter how aging adults biologically respond to pollutants. In a controlled human toxicokinetic study (exposure chamber; 12 m³), aging volunteers (n=10; >58 years) were exposed to propylene glycol monomethyl ether (PGME, CAS no. 107-98-2) at 50 ...

Background and Aim: Exposure to hexavalent chromium in plating operations is associated with skin ulceration, contact dermatitis, respiratory tract irritation, cancer, and kidney damage. We investigated the possibility of using biological monitoring to assess exposure to hexavalent chromium in chrome-plating workers. We compared mean Cr6 concentrations in the breathing zone plus urine chromium,...
متن کاملThe Effects of Noise and Whole Body Vibration on Urinary Metanephrine and Normetanephrine
Background and Aim: Little attention has been paid to the effects of combined exposure to noise and vibration. Exposure to noise and vibration can effect stress hormones and may lead to high blood pressure and cardiovascular disorders. This study aims to investigate the effects of noise and vibration on urinary Metanephrine and Normetanephrine among men. Methods: In this experimental study, 30 ...
متن کاملImpact of biological and environmental variabilities on biological monitoring--an approach using toxicokinetic models.
Biological monitoring of occupational exposure is characterized by important variability, due both to variability in the environment and to biological differences between workers. A quantitative description and understanding of this variability is important for a dependable application of biological monitoring. This work describes this variability, using a toxicokinetic model, for a large range...
