Comparative mammalian metabolism of vinyl chloride and vinylidene chloride in relation to oncogenic potential.

abstract：BACKGROUND:Toxicology studies have shown adverse effects of developmental exposure to industrial phenols. Evaluation in humans is challenged by potentially marked within-subject variability of phenol biomarkers in pregnant women, which is poorly characterized. OBJECTIVES:We aimed to characterize within-day, between-da...
