国内外优先评估化学品筛选方法与清单概述

优先评估化学品名录对推进有毒有害化学品的管控、保护环境和人类健康具有重要意义。综述了国内外优先评估化学品筛选方法的发展、原则和步骤，总结了筛选评估流程中重点关注的多种危害特性，比较了各国优先评估化学品名录及其在各国/组织的禁止/限制情况，并分析其在我国的生产状况。结果表明，各国家/组织共筛选出1 146种优先评估化学品，有239种在至少2个国家/组织中被列为优先评估化学物质，有208种在我国生产使用，但其中164种尚未列入我国优控化学品名录，可作为下一步风险评估的对象。邻苯二甲酸二（2-乙基己基）酯（DEHP）被所有国家/组织列为优先关注化学品，接下来应严格管控塑料制品中的DEHP，或寻找合适的替代物。研究可为我国优先评估化学品的筛选与环境管理提供参考。

Overview of Screening Methods and Lists of Priority Assessment Chemicals

The priority assessment chemical list is of great significance for promoting the management of toxic and hazardous chemicals as well as protecting the environment and human health. The main objective of this study was to overview the development, principles and steps of screening methods for priority assessment chemicals, and summarize the various hazard properties that are focused on in the screening process, and then compare the list of priority assessment chemicals in various countries. In addition, it compared the status of its prohibition/restriction in various countries/organizations, and analyzed the relationship with our country''s production. It is found that the list contains a total of 1,146 priority assessment chemicals, of which 239 are listed in more than two countries. Among them, 208 are produced and used in our country but 164 are not yet been listed in the inventory, and further risk assessment is urgently needed. Di (2 ethylhexyl) phthalate (DEHP) is listed as a priority chemical by all countries / organizations. Next, DEHP in plastic products should be strictly controlled or suitable substitutes should be found.This study provides a scientific basis for screening and environmental management of priority assessment chemicals.
