摘要
分析并讨论了杭州市城市空气中苯系物的浓度、污染现状、来源及其与车流量、温度的关系.结果表明,杭州市环境空气中苯系物污染十分严重,6种苯系物的浓度平均达38.96～192.62μg/m3,其主要来源于机动车尾气排放.
The concentration of BTEX in the air of Hangzhou was determined. Relationships between BTEX's concentration in air, traffic intensity and temperature were evaluated. The results indicated that the pollution of BTEX in the air of Hangzhou is very serious and the total amount of BTEX, on the average, are 38.96~192.62 μg/m3. The discharge of tail gas of vehicles is the main source of BTEX in the air of Hangzhou.
