Abstract
Total mass particulates and benzopyrenes have been determined to evaluate the specific pollution by vehicles on a section (6 km) of a highway. The traffic density generated an increase of 30% mass particulates in nighttime and 44% during daylight. Concentrations of benzopyrenes in air have doubled compared to the period before traffic.
摘要
已测定了总颗粒物和苯并芘，以评估某高速公路一段6公里路段上车辆造成的特定污染情况。交通密度致使夜间的颗粒物质量增加了30%，白天增加了44%。与交通流量增加之前相比，空气中苯并芘的浓度增加了一倍。
