华东地区某市重点行业优控环境激素的筛选及分布特征

Screening and distribution of priority environmental hormones in the key industrial sectors in a city of East China

为筛选华东地区某市重点行业优先控制环境激素,基于美国"内分泌干扰物筛选计划"、欧盟"内分泌干扰物共同体战略"等研究,本文整理得到重点关注环境激素名单,并对其在该市重点行业企业的生产使用情况进行了调查。结果表明,壬基酚、双酚、乙草胺等51种重点关注环境激素中,13种在重点行业企业的生产和使用中被涉及。根据上述13种环境激素的生产、使用量和涉及企业数等,进一步筛选得到4种建议区域优先控制环境激素,分别为苯乙烯、双酚A、邻苯二甲酸二乙酯和邻苯二甲酸二丁酯。从地区分布上看,4种建议区域优先控制环境激素的生产和使用主要集中在工业聚集区,主要涉及的行业为化学原料和化学制品制造业。研究结果为筛选优先控制环境激素、进一步识别其风险、重点突出地加强对其的管理和控制提供了理论依据。

In order to screen out environmental hormones for priority control in key industries of a city in East China, based on the US “Screening Plan for Endocrine Disruptors” and EU “Community Strategy for Endocrine Disruptors”, a list of environmental hormones including 51 chemicals was sorted out and the production and use of enterprises in key industries in the city were investigated. The results showed that among key 51 environmental hormones, including nonylphenol, bisphenol and ethoxamine, 13 of them were involved in the production and use of investigated key industrial enterprises. Furthermore, four of them, namely styrene, bisphenol A, diethyl phthalate and dibutyl phthalate, were screened as regional priority control environmental hormones, based on their production and consumption, as well as the enterprises involved in this city. The enterprises refer to four recommended regional priority environmental hormones are mainly located in chemical industrial park, and mainly involving chemical materials and chemical products industry. The results provide a theoretical basis for screening environmental hormones, further identifying their risks, and emphatically strengthening their management and control.
