大气有机污染分析和评价I．采样方法及采样误差

对近１０年来国外有关大气污染物的采样方法、有机污染物在气、固相中的分配以及采样误差的主要文献做了简要回顾。对不同采样器的采样效率、误差来源及误差校正方法进行了讨论。列举了一些富有指导意义的研究成果和结论。可以看出，在消除或限制了采样误差后，所得分析结果为客观评价环境污染问题提供了更可靠的依据。

The Analysis and Evaluation of Atmospheric Organic Pollution I.Sampling Methods and Artifacts

his article reviews briefly the foreign literature concerning sampling methods,distributionof organic pollutants both in gas and solid phases as well as sampling errors in the research of atmospheric organic pollutants during the last 10 years. Sampling efficiencies of various samplersand sources of error along with their corrections were discussed and some guiding achievementsand significant conclusions were listed.It is shown that analytical data will provide more reliable basis for the objictive evaluation of environmental pollution if sampling errors could he reduced oreliminated.
