摘要
PCDD/Fs具有"致癌、致畸、致突变"等"三致"的特性,PCDD/Fs对生态系统和人体健康均有很大的危害。文章对比研究了联合国环境规划署、澳大利亚、中国、台湾等国家和地区的二噁英排放量和排放清单,结果表明各位为二噁英削减工作取得了很大的成绩,而且各国的排放量和排放清单结构差异比较大。联合国环境规划署统计表明68个国家的二恶英年总排放量每约58500克毒性当量(WHO-TEQ),排放到空气中占了总排放量的45%,世界各国二噁英的排放清单差异较大,如澳大利亚以交通运输和金属冶炼为主,我国的金属冶炼(45.6%)排放量最大,台湾则是炼铜、小型焚烧厂的贡献率比较大。
PCDD/Fs are harmful to ecosystem and human health because of the characteristics of carcinogenic, teratogenic and mutagenic. The work investigated the emission inventory of PCDD/Fs among the United Nations Environment Programme, Australia, and China, Taiwan and other countries and regions. The results showed that for every country and region had made great achievements in PCDD/Fs emission reduction. United Nations Environment Programme Statistics showed that the total annual emission amount of dioxin among the 68 countries was 58500 g in toxic equivalents （WHO-TEQ）, which discharged 45 % of the total amount of dioxins into the air. The emission inventories were different for every country and region, such as the USA, Australia, China, and Taiwan. The courtyard burning contributed mostly for USA in the year of 2000, while transportation and smelting contributed largely for Australia, but the maximum emission was metal smelting for China and Taiwan was copper, small incinerator.
