我国环境空气中降尘测定方法和评价标准的适用性探讨

环境质量日益得到关注的今天,大气降尘作为环境空气质量的必测指标,其检测方法的适用性尤显重要。目前国内使用的测定空气中降尘的方法为1995年实施的重量法,通过对该方法与国内外监测方法相比较,并结合本实验室多年来的实验数据,综合各评价标准考察了目前实验室运用该方法的适用性及有效性,同时提出改进建议。

The environmental quality has gained increasing attention, atmospheric dust as a measurement of the ambient air quality indicators, applicability of the detection method is particular important. Determination of dust in the air of the currently used methods is gravimetric method for implementation in 1995. This article compared this method with domestic and international monitoring methods, combined with the laboratory for many years of experimental data, investigation laboratories currently use this method on comprehensive evaluation criteria＇s applicability and validity, and make recommendations for improvement.
