秦皇岛市大气颗粒物来源解析研究

对秦皇岛海港区和山海关区的颗粒物来源进行了定性识别和定量解析。并考察了重点污染源－－我国最大的煤码头秦皇岛港煤码头对市区扬尘和ＴＳＰ中的碳的影响。得出秦皇岛市海港区和山海关区ＴＳＰ主要来源为风沙、扬尘，其次为燃煤飞灰和海盐尘。气象条件特别是风向对ＴＳＰ各源发担率的影响很大，秦皇岛市煤码头是该区域ＴＳＰ中碳的主要来源。

Source Analysis of Air Particulate in Qinhuangdao city

In this paper,the theory of the chemical mass balance(CMB),which is the most widelyused in source analysis of air particulate in urban atmosphere was introduced. We have identified thesources of particulate in both Haigang and Shanguan districts of Qinhuangdao city and quantified thecontribution of different source types to receptor concentrations.We have also investigated the effectof the largest coal dock in China-Qinhuangdao Coal Dock on background dust and the carbon elementin total suspended particulate(TSP).It showed that the major source of TSP in both Haigang andShanhaiguan districts was wind blowing and background dust, then the coal-combustion ash and seasalt.We also know that weather conditions especially wind direction can easily affect the source contributions of TSP.Finally we draw a conclusion that Qinhuangdao Coal Dock is the major source ofthe carbon element in TSP in this area and the levels of both Haigang and Shanhaiguan districts affected bv the Coal Dock are different under different weather conditions.
