三氯乙酸在空腹和非空腹大鼠服用次氯酸钠1小时后的肠道内容和血浆中被发现。因此,其形成不依赖于次氯酸钠与肠道中的外来有机物的相互作用。二氯乙酸也在所有处理过的动物中被发现。当检测到三氯乙酸时,氯仿通常也存在。二氯乙腈在用次氯酸钠处理的3只非空腹大鼠中有2只的肠道内容中被发现。将8毫克次氯酸钠/毫升添加到非空腹大鼠肠道内容的体外中产生了二氯乙酸、三氯乙酸、二氯乙腈和三氯乙腈。
Trichloroacetic acid was found in the gut contents & plasma of fasted & nonfasted rats 1 hr after dosing with sodium hypochlorite. Thus, the formation is not dependent on the interaction of sodium hypochlorite with foreign organic material in the gut. Dichloroacetic acid was also found in all treated animals. Chloroform generally was present when trichloroacetic acid was detected. Dichloroacetonitrile was found in the gut contents of 2 of 3 nonfasted rats treated with sodium hypochlorite. Addition of 8 mg sodium hypochlorite/ml to nonfasted rat gut contents in vitro produced dichloroacetic acid, trichloroacetic acid, dichloroacetonitrile, & trichloroacetonitrile.
