氯苯甲醚类化合物(CAs)是葡萄酒和饮用水中普遍存在和亟待去除的嗅味物质,在世界各地不同介质中均可发现CAs的存在。CAs主要来自于五氯酚及其钠盐的微生物降解产物,具有持久性和可远距离迁移等持久性有机污染物(POPs)属性,此外该类污染物还具有生殖毒性和神经毒性等。目前国内外尚未建立CAs测定的标准方法。以CAs中嗅味阈值最低的2,4,6-三氯苯甲醚(TCA)和毒性最强且近年被列为POPs的五氯苯甲醚(PCA)为主要研究对象,对CAs污染物的来源及分布、产生机理、代谢转化与毒性效应、检测及去除方法展开论述。研究表明:CAs是一类污染来源和分布范围广,具有一定的毒性效应的物质,目前有关CAs的研究较少,今后应加强对CAs的环境迁移转化规律和毒理学研究。
Chloroanisole compounds (CAs) are common and urgent odor-removing substances found in wine and drinking water. CAs are found in different media around the world. CAs are mainly derived from the microbial degradation products of pentachlorophenol and its sodium salts, have persistent organic pollutants (POPs) properties such as persistence and long-distance transport, and also have reproductive toxicity and neurotoxicity. At present, the standard method of CAs determination has not been set up at home and abroad. In this paper, 2,4,6-trichloroanisole (TCA) with the lowest odor threshold in CAs and pentachloroanisol (PCA) with the highest toxicity and POPs listed as POPs in recent years were selected as the main research objects. The effects of CAs pollutants Origin and distribution, production mechanism, metabolic transformation and toxic effects, detection and removal methods to discuss. Studies have shown that CAs are a kind of substance with a wide range of sources and distributions and some toxicological effects. There are few studies on CAs at present, and the research on the laws of environmental migration and toxicology of CAs should be strengthened in the future.
