【摘要】 为了揭示峨眉山大气漂尘的化学特征 ,研究小组分别在 1998,1999,2 0 0 0年使用小型大气采样器进行采样 ,并测得样品中含有水溶性化学成分 (Na+,K+,Mg2 +,Ca2 +,SO42 - ,NO3 - ,NH4+和 Cl- )和酸溶性化学成分 (Pb和 Zn)。这一地区三年的大气成分与1990年的相似 ,而且峨眉山的 Na+,Cl- ,SO42 - ,NO3 - ,Ca2 +,NH4+,Pb和 Zn浓度分别比日本山形县鹤岗的要高出 4～ 15 ,3～ 19,3～ 5 ,3～ 6 ,13～ 2 3,4～ 7,11～ 2 8和 10～ 2 3倍之多。更多还原

【Abstract】 Aerosol samples were collected in Emeishan area, Sichuan Province, China, to reveal a chemical characteristics of particulate atmospheric matter by using a handy air sampler,in 1998, 1999 and 2000. The water soluble chemical components (Na +,K +,Mg 2+,Ca 2+,SO 4 2+,NO 3 -,NH 4 + and Cl -) and acid-soluble chemical components (Pb and Zn) were measured.Compositions of aerosol in China in 1998, 1999 and 2000 were similar to those in 1990.Concentrations of Na +, Cl -, SO 4 2-,NO 3 -,Ca 2+,NH 4 +, Pb and Zn in Emeishan were 4 to 15, 3 to 19, 3 to 5, 3 to 6, 13 to 23, 4 to 7, 11 to 28 and 10 to 23 times higher than those in Tsuruoka, Yamagata Prefecture, Japan respectively.更多还原
