• 致癌性证据

分类：B2；可能的人类致癌物。分类依据：狄氏剂在经口给予七种小鼠品系时具有致癌性。狄氏剂结构与产生啮齿动物肿瘤的化合物（艾氏剂、氯丹、七氯、七氯环氧和氯菌酸）相关。人类致癌性数据：不足。动物致癌性数据：充分。

CLASSIFICATION: B2; probable human carcinogen. BASIS FOR CLASSIFICATION: Dieldrin is carcinogenic in seven strains of mice when administered orally. Dieldrin is structurally related to compounds (aldrin, chlordane, heptachlor, heptachlor epoxide, and chlorendic acid) which produce tumors in rodents. HUMAN CARCINOGENICITY DATA: Inadequate. ANIMAL CARCINOGENICITY DATA: Sufficient.

• 致癌性证据

在美国环保局(EPA)的《致癌物风险评估指南(征求意见稿)》框架内，建议与小鼠肝脏肿瘤反应相关的艾氏剂/狄氏剂的最合适的癌症风险描述符是“不太可能是人类致癌物”，这个描述符与EPA引用的苯巴比妥的例子一致。

Within the framework of EPA's Proposed Guidelines for Carcinogen Risk Assessment, it is proposed that the most appropriate cancer risk descriptor for aldrin/dieldrin, relating to the mouse liver tumor response, is 'not likely a human carcinogen', a descriptor consistent with the example of phenobarbital cited by EPA.
