PAHs ratios are used to identify the source of PAHs, the result showed that the major source of 16 PAHs in Urumqi Xinshi district was coal-bustion and vehicle discharges . Mercury in TSP samples were digested by aqua regia and analyzed by AFS analyzer .The results showed that : the concentration of mercury was 0.869-1.91 ng m-3.Compared with other cities in the rest of the world , the concentration of mercury was very high. The concentration of mercury in heating season was lower than that in no-heating season.

对大气颗粒物样品中的汞，采用王水于特弗龙消解罐中加热消解的方法进行处理，稀酸定容后采用原子荧光光谱法对样品中的汞进行测定，测定结果为。869-1.91 ng m-3，与国外城市相比较高；实验测得非采暖期乌鲁木齐大气颗粒物汞浓度的均值高于采暖期颗粒物中的汞浓度，其原因可能是由于随着非采暖期温的升高，长期积累在土壤、水体环境中的汞向大气中释放，附着在颗粒物上，过了燃煤的影响。
