摘要

[Objective] The aim was to study the concentration characteristics and sources of chemical elements in atmospheric fine particles (PM2.5) in autumn in Xi'an City. [Method] By means of mini-volume sampler, PM2.5 samples in atmosphere in Xi'an were collected in October 2009, and the concentration characteristics and sources of elements in PM2.5 were analyzed. [Result] The average mass concentration of PM2.5 in atmosphere in autumn in Xi'an City was 168.44 μg/m3 which was higher than that of Beijing and Pearl ...
