Environmental health perspectives, 104 Suppl 6, 1147-1149 (1996-12-01)
Biological markers of internal dose are useful for improving the extrapolation of health effects from exposures to high levels of toxic air pollutants in animals to low, ambient exposures in humans. Previous results from our laboratory have shown that benzene

Carcinogenesis, 13(7), 1217-1220 (1992-07-01)
Results of experiments in our laboratory have shown that benzene is metabolized by animals in part to an intermediate that binds to cysteine groups in hemoglobin to form the adduct S-phenylcysteine (SPC). These results suggested that SPC in hemoglobin may

Archives of toxicology, 66(5), 303-309 (1992-01-01)
Benzene is metabolized to intermediates that bind to hemoglobin, forming adducts. These hemoglobin adducts may be usable as biomarkers of exposure. In this paper, we describe the development of a gas chromatography/mass spectroscopy assay for quantitating the binding of the

Cysteinyl adducts of hemoglobin (Hb) and albumin (Alb) formed via reactions with reactive species were measured in 48 subjects exposed to styrene (0.24-55.2 ppm) and to styrene-7,8-oxide (SO) (2.65-107 ppb) in a factory producing boats in the USA. Hb and

Tellurium compounds are effective antioxidants and chemoprotectors, even more active than their selenium and sulfur analogues. In addition to these properties, some selenium compounds, such as selenocysteine Se-conjugates, possess significant chemopreventive and antitumor activities, and selenol metabolites are considered as
