地木耳挂袋法监测大气SO_2污染的可行性研究

A STUDY ON THE FEASIBILITY OF MONITORING SO_2POLLUTION BY USING N.COMMUNE BAGS

本文用地木耳和碱片同步监测了白银地区某冶炼厂及其四周大气中的二氧化硫浓度。经地木耳含硫量与大气二氧化硫污染浓度的相关分析表明：地木耳含硫量与大气二氧化硫污染浓度之间有密切相关性。利用地木耳挂袋法监测大气ＳＯ＿２污染具有可比性强、容污量大、布点灵活，经济方便等优点，适宜于大范围内甚至世界范围内统一监测大气ＳＯ＿２污染应用。

Byusing N.commune and alkali paper,we synchronously monitored the Sulfur Dioxide con-centration inside a smeltry and around it in Baiyin region.Based on correlation analysis,the sul-fur contents in N.commune was closely related to the SO_2 concentration in the air.It has many advantages to use N.commune in monitoring SO_2 pollution,such as easily being compared,con-taining a large amount of the pollutant,freely selecting monitoring sites,economizing and conve-nience.N.commune can be used to monitor SO_2 pollution in large area even in the world.
