Relationship Between Preceding Controlled PAH and Micro- compositions in Atmospheric Particles from Guangzhou Cheng Yu Sheng Guoying Liu Dehan Fu Jiamo Yang Xiuzhen (Guangzhou Institute of Geochemistry,Chinese Academy of Sciences,Guangzhou 510640) Wu Haoqing (Department of Chemistry,Fudan niversity,Shanghai 200433) AbstractCharacteristic of micro-compositions and concentrations of preceding controlled PAH (PCPAH) in atmospheric particles collected from different function zones of Guangzhou in au- tumn were studied in this paper It was indicated that atmospheric individual particles are main-. ly composed of carbonaceous spheroids,organicmicro-particulate,organic clasts,various miner- als and bioclasts,which varied with function zones and came from anthropogenic, geogenic and biogenic origins.Fifteen PCPAH published by SEPA are detected in atmospheric particles and 27. 38228. 56 / 3. their concentrations varied with function zones are ng m It was discovered that concentrations of PCPAH have well good correlation with the percentages of 3 compositions, carbonaceous spheroids,organic microparticulate and organic clasts. , - , , , .
