WebCytochrome P450 oxidation in the liver is also the primary metabolism pathway following inhalation exposure to bromodichloromethane (Allis et al. 2001). Several studies have shown that as the bromodichloromethane exposure level increases, the percentage of metabolism due to CYP2E1 decreases (Allis and Zhao 2002; Zhao and Allis 2002). WebToxicokinetics - Absorption, Distribution, Metabolism, Excretion. Absorption: Toxicant enters the blood from site of exposure. Distribution: Toxicant leaves the circulation, enters tissues. Metabolism: Enzymes catalyze the chemical conversion of a toxicant; often into a more water-soluble form. Excretion: Elimination of toxicant from the body.
