亚乙基硫脲曾被广泛用于氯丁橡胶及其他橡胶的固化,同时也被少量用于生产杀虫剂,但由于其对人体的危害,目前已基本被淘汰。 亚乙基硫脲的LD50为1832mg/kg(大鼠口服),属于低毒类化学物质。 对于亚乙基硫脲的环境浓度限制暂时没有一个统一标准。 其中美国某些州规定空气中限制为0~0.7μg/m3,EPA目前建议水中限制为0.44μg/L。 亚乙基硫脲属于国际癌症研究机构(IARC)第三类致癌物——对人类的致癌性不确定(曾经为2B类),但在动物实验中致癌、致畸性检测均为阳性。 在对小鼠的致癌性实验中,亚乙基硫脲引起了甲状腺滤泡细胞癌、垂体前叶腺肿瘤及肝癌;对大鼠则导致甲状腺上皮细胞癌。 除此之外,与硫脲、丙硫氧嘧啶等抗甲状腺物质一样,亚乙基硫脲会导致人类甲状腺肿大。
