【摘要】 目的 :调查了解郑州市 1998年大气污染状况 ,以期加大治理力度 ,保护生态环境。方法 :用紫外荧光法测定二氧化硫 (SO2 ) ,用化学发光法测定氮氧化物 (NOx) ,用重量法测定总悬浮颗粒物 (TSP)和降尘 (FD) ,用铬酸钡比色法测定硫酸盐化速率 (SV)。在大气污染物测试基础上 ,按照国家规定的评价标准分析了郑州市大气环境中主要污染物及污染类型。结果 :该年度郑州市大气各污染物对污染的影响作用大小顺序为 :TSP >NOx>FD >SO2 。结论 :郑州市 1998年综合污染水平为中度污染 ,属煤烟型污染更多还原

【Abstract】 Aim: To investigate the conditions of air pollution in 1998. Putting forward the countermeasure for decreasing air pollution. Methods: Measuring SO 2 by ultraluminescence, NO x by emicaliluminescence, TSP and FD by gravimetry and SV by BaCrO 4 colorimetry. The main pollutants and pollution type of Zhengzhou were analyzed following the state evaluation standard. Results: The sequence of pollutants was TSP>NO x>FD>SO 2 by contributing to air pollution. Conclusion: The comprehensive pollution level of Zhengzhou in 1998 was medium. The pollution mainly arose from burning coal and next from automobile and dust.更多还原
