摘要
基于韦伯——费希纳(Weber-Fischna)定律并加以拓广,指出空气污染物浓度成等比变化时,其对人体和生态环境产生的危害程度成等差变化;应用‘等比赋值,等差分级’的指数标度法,确定出7项空气污染物的日平均浓度的环境空气质量标准,并与国家《环境空气质量标准(GB3095-1996)》进行了比较。结果表明.除NO_2、CO和TSP在两种标准中各有一个级别的浓度限值差异稍大外,其余空气污染物的两种标准的相同级别浓度限值十分接近,从而为制订的国家《环境空气质量标准(GB3095-1996)》提供了理论依据。
Based on Weber-Fischna's law. the person's body and ecological environment suffer from the impact of equi-difference extent, as the concentration of an air pollutant changes with equi-ratio. Environmental air quality standards of the mean concentration daily on the 7 kinds of air pollutants were worked out by the exponential scale of 'equi-ratio valuation, equi-difference classification'. Comparison between air quality standards based on Weber-Fischna's law and Chinese air quality standards (GB309S-96) was earned out. The results show that the majority of the differences of the same class concentration values of all the pollutants are unmarked, which the theoretical basis for the formulation of environmental air quality standards. (GB3095-1 996) presents on.
