| 中文摘要 | 建立中国分省燃煤汞排放清单 ,对于研究汞的大气化学转化、迁移和沉降 ,制定中国汞污染控制对策具有重要意义 .本研究按经济部门、燃料类型、燃烧方式和污染控制技术将排放源划分为 6 5种不同类型 ,根据各类型的煤炭消费量、燃料汞含量和汞排放因子计算汞排放量 ,最终建立了分省燃煤汞排放清单 .用 2组原煤汞含量数据资料计算的 2 0 0 0年中国燃煤大气汞排放量分别为 16 .1 6t和 2 .19 5t,其中绝大部分汞排放来自工业、电力和生活消费 ,分别占 4 6 %、35 %和 14 % .Hg0 、Hg2 + 和Hgp在中国燃煤大气汞排放中所占的比例分别为 16 %、6 .1%和 2 3% .中国燃煤汞排放在各地区间有较大差异 ,排放量较大的省份有河南、山西、河北、辽宁和江苏 ,均超过 10t/a .; Mercury emission inventory by province from coal combustion in China was developed by combining fuel consumption, mercury content in fuel and emission factors after combustion in this study. The study is intended to provide an understanding of mercury transformation, transportation and deposition in atmosphere, as well as propose measures to control mercury pollution in China. Mercury emission sources were classified into 65 categories by economic sectors, fuel types, boiler types and pollution control technologies. For two different data sets of mercury content in coal the total amounts of mercury released into atmosphere in 2000 in China were estimated at about 161.6 tons and 219.5 tons, respectively. The biggest three source sectors were industry, power plants, and residential use, contributing 46%, 35% and 14% of total mercury emissions, respectively. The shares of elemental mercury (Hg0), oxidized mercury (Hg 2+) and particulate mercury (Hg_p) were 16%, 61% and 23%, respectively. The spatial distribution of mercury emissions from coal combustion in China is not uniform. Henan, Shanxi, Hebei, Liaoning and Jiangsu contributed large amounts of mercury emissions, exceeding 10t穉 -1.; 国家重点基础研究发展规划 (973 )项目 (2 0 0 2CB2 1160 0 ) |
