汉口五条交通主干道气铅的调查与研究

在对于汉口5条交通主干道“气铅”进行监测,并与使用无铅汽油前空气中铅污染进行比较后,可以看出主干道的气铅有明显的下降,但城市城区铅污染仍然严重。在使用无铅汽油后,城市中2次扬尘、路况、车况不好等是使气铅含量较高的主要因素。因此,要继续降低城区主干道的气铅含量、既要治“油”,又要治“尘”,还须在实施城市“蓝天工程”中进行综合治理。

Investigation and Study on Atmospheris Lead of Five Main Trunk Highway in Hankou

The atmospheric lead of five main trunk highway in Hankou was detected.
