客车车内空气质量评价

Evaluation of air quality inside buses

根据国家相关标准,建立了客车内空气质量评价标准建议值与客车空气品质等级。选择氨、甲醛、苯、甲苯和二甲苯作为评价指标,以污染物质量浓度与环境标准建议值之比为空气质量分指数,采用综合指数法对客车空气品质进行了评价;结果表明,甲醛和苯系物对车内空气质量影响较大,氨基本没有影响;采用综合指数法评价车内空气质量是可行的。

The suggestion values for the evaluation standard of air quality inside buses and the quality grades are set up based on the related State air quality standards. The comprehensive index method is used to evaluate the air quality inside buses with the concentration of ammonia, formaldehyde, benzene, methylbenzene and dimethylbenzene as the evaluated indexes and the ratio of the actual concentration of the pollutant to its standard concentration as the divided index. The results indicate that formaldehyde, benzene, methylbenzene, and dimethylbenzene have marked effects on the air quality inside buses while ammoniacs effect is quite minor. The comprehensive index method is feasible for evaluating the air quality inside buses.
