摘　　要：环境气体监测有主动采样和被动采样。被动采样由于其简单方便、成本低、无动力、准确可靠、质量轻等优点适宜用于偏远、条件差的山区和县城。利用被动采样和自动监测方式监测宜昌市大气中的SO2和NO2,并作t检验比较,验证了被动采样在此区域的可行性。Active and passive sampling methods are often applied in the determination of the ambient air. Passive sampling is suitable for remote,low condition mountain areas and counties because of its simplicity, convenience, low cost- effectiveness, no pump- dependent, high accuracy and precision, light- weight, etc. The comparison of passive sampling and automated monitoring for the determination of ambient sulfur dioxide and nitrogen dioxide concentrations in Yichang City was made out,and t- test was analyzed,feasibility of the passive sampling in the region was proved.
