摘　　要：[目的]观察普通家用轿车内空气中甲醛和总挥发性有机物(TVOC)的污染状况。[方法]随机选取正常使用中的车龄为1个月至6年的普通家用轿车为测试对象,参照《民用工程室内环境污染物控制规范》(GB50325—2001)规定,检测车内空气中甲醛和TVOC的浓度。[结果]受测的72辆家用轿车中,TVOC超过0.5mg/m3的有31辆,占43%;甲醛含量0.08mg/m3以上的有11辆,占15%;上述两项指标同时超标的有9辆,占12.5%。[结论]家用普通轿车内空气中的甲醛和TVOC浓度水平较高,TVOC超标现象更为普遍。上述两项指标变化与车龄无明显的数量关系。[ Objective ] To investigate the contents of organic pollutants inside passenger vehicles. [ Methods ] Concentrations of formaldehyde and total volatile organic compounds （ TVOCs ） in the air inside 72 passenger vehicles were determined based on GB50325-2001 under static conditions. [ Results ] About forty-three percent of detected samples contained more than 0.5 mg/m3 TVOCs, and fifteen percent of the samples contained more than 0.08 mg/m3 formaldehyde. About fifty-four percent of the samples were in accordance with GB50325-2001. [ Conclusion ] Formaldehyde and TVOC concentrations are exceeded standard in a few vehicles. Relationship is not found between the mileage of vehicle and pollution condition.
