Abstract

Ethylenethiourea (ETU) has been recognized as a compound with adverse toxicological properties. It may occur in ethylenebis(dithiocarbamate) (EBDC) fungicides as a by-product and/or a degradation product. Restrictions have been issued by the Italian Health Authority to keep the level of ETU in EBDC formulations under 0.5% (on an EBDC technical product basis). A survey was carried out on 85 samples of commercial formulations from the Italian market to verify compliance with the above limitation. ETU was extracted by methanol and determined by gas chromatography with a flame ionization detector. Three of the 85 samples (3.5%) exceeded the limit of 0.5% established by the Italian legislation for ETU.

摘要

乙撑硫脲（ETU）被认为是一种具有不良毒理学特性的化合物。它可能作为副产物和/或降解产物存在于乙撑双二硫代氨基甲酸盐（EBDC）类杀菌剂中。意大利卫生当局已发布限制措施，将EBDC制剂中ETU的含量控制在0.5%以下（以EBDC技术产品为基础）。对意大利市场上85个商业制剂样品进行了调查，以核实是否符合上述限制。ETU用甲醇提取，并用带有火焰离子化检测器的气相色谱法测定。85个样品中有3个（3.5%）超过了意大利法规规定的ETU 0.5%的限量。
