Abstract

Bromodichloroacetic acid is a haloacetic acid that forms when drinking water supplies containing natural organic matter are disinfected with chlorine-containing oxidizing compounds and when bromide is present in the source water. Bromodichloroacetic acid was nominated for toxicity and carcinogenicity studies by the American Water Works Association Research Foundation and the United States Environmental Protection Agency because of widespread human exposure to this water disinfection by-product and because related dihaloacetic acids were found to be carcinogenic to the liver of rats and mice. Male and female F344/N rats and B6C3F1/N mice were exposed to bromodichloroacetic acid (greater than 97% pure) in drinking water for 2 weeks or 3 months, and male and female F344/NTac rats and B6C3F1/N mice were exposed for 2 years. Genetic toxicology studies were conducted in Salmonella typhimurium, Escherichia coli, and mouse peripheral blood erythrocytes. (Abstract Abridged).

溴氯乙酸在 F344/N 大鼠和 B6C3F1/N 小鼠中的毒理学研究,以及溴氯乙酸在 F344/NTac 大鼠和 B6C3F1/N 小鼠中的毒理学和致癌性研究(饮用水研究)。
溴氯乙酸是一种卤乙酸,当含有天然有机物的饮用水经含氯氧化化合物消毒,且原水中含有溴时就会形成这种物质。美国自来水协会研究基金会和美国环境保护局提名对溴氯乙酸进行毒性和致癌性研究,因为人类广泛接触这种水消毒副产品,而且发现相关的二卤乙酸对大鼠和小鼠的肝脏具有致癌性。雌雄 F344/N 大鼠和 B6C3F1/N 小鼠接触饮用水中的溴氯乙酸(纯度大于 97%)2 周或 3 个月,雌雄 F344/NTac 大鼠和 B6C3F1/N 小鼠接触溴氯乙酸 2 年。在鼠伤寒沙门氏菌、大肠杆菌和小鼠外周血红细胞中进行了遗传毒理学研究。(摘要有删节)。
