Abstract
Carcinogenic N-nitrosodiethanolamine has been found at concentrations varying from 15 to 5700 mg/liter in several leading French brands of antifreeze. Moreover, mixtures of antifreezes which, separately, are innocuous, can form this nitrosamine which appears to arise from interaction of triethanolamine derivatives with sodium nitrite. It is recommended that sodium nitrite be abandoned as an anticorrosion additive.
摘要
在法国几个主要品牌的防冻液中，已发现致癌物质N-亚硝基二乙醇胺，其浓度在15至5700毫克/升之间变化。此外，单独使用时无害的防冻液混合物，可能会形成这种亚硝胺，它似乎是由三乙醇胺衍生物与亚硝酸钠相互作用产生的。建议放弃使用亚硝酸钠作为防腐添加剂。
