乘用车内甲醛、TVOC的浓度检测

Concentration test of formaldehyde and TVOC in passenger cars

选择了11辆不同品牌与使用时间的乘用车,测定车内空气中甲醛、总挥发性有机化合物(TVOC)的浓度,并依据相关国家标准限定值对检测结果进行分析,发现车内TVOC浓度超出限定值程度远高于甲醛,同时评估了开启车门通风以及使用车内空调对两者浓度变化的影响。

In this paper, the concentration of formaldehyde and totalvolatile organic compound (TVOC) in the air of 11 different brandpassenger cars with different off-line time was determined. According torelevant national standards, the concentration of TVOC in these cars wasfound exceeding the limit value much higher than formaldehyde. Also,the influence of different conditions such as door opening ventilation andair conditioning on the concentration of these two kinds of pollutants wasevaluated.
