【摘要】 本文研究了京津地区大气颗粒物及其化学组成,介绍12种元素Cd、Cu、K、Mn、Pb、Zn、Fe、Na、Ni、Cr、Sr、Ba;5种离于F^-、Cl^-、NO₃^-、SO₄²、NH₄⁺和26种有机污染物的区域分布。用有机物的奇/偶碳数比值估计了大气颗粒物的来源。用无机元素的判别法分析了北京、天津、廊坊和蓟县之间大气污染的相互影响。更多还原

【Abstract】 Total suspended participates (TSP) and their chemical composition in Beijing-TJanjin Area have been analyzed. There were 12 elements (Cd, Cu, K, Mn, Pb, Zn, Fe, Na, Ni, Cr, Sr, Ba), 5 kinds of ions (F, Cl, NO, SO, NH) and 26 kinds of organic pollutants in the regional distribution. The sources of TSP were estimated by means of orgenic odd/even carbon number rates. Atmospheric pollution affected mutually among Beijing, Tianjin, Lanfang anf Gixian County were studied with identification analysis of inorganic elements.更多还原
