摘要：
Vehicle emissions where Pb containing gasoline is used contributes to toxic metal urban air pollution and is still a matter of concern. An assessment of the extent of roadside Pb pollution in Harare (Zimbabwe) was undertaken. Pb was measured in soil and vegetation roadside samples. For busy roads Pb levels in soil and vegetation indicated a significant level of Pb pollution in the environment nearby the road. The Pb levels at the kerb of busy roads (Simon Mazorodze Road) were 1480 and 23.3 mug.g-1. in soil and vegetation, respectively, and the levels found for less busy roads (Mutare Road) were 404 and 8.0 mug.g-1 in soil and vegetation samples respectively. The gradual phasing out of the level of Pb in leaded gasoline is suggested.
