家用轿车内甲醛和总挥发性有机物污染状况调查

A Study on Organic Pollutants inside Passenger Vehicles in Shenzhen

  • 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》(GB 50325-2001)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 0.5 mg/m3的有 31辆,占 43%; 甲醛含量 0.08 mg/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。

     

    Abstract: 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.
