Abstract: | Roadside dusts and soils were collected from various nonindustrial districts in Cincinnati, Ohio, USA, and analyzed for lead
and copper contents. Results showed that the recent lead phase-down action has reduced the level of lead, but the concentrations
of both metals are still higher than the background levels for normal soil. Elevated concentrations of copper in heavily traveled
highways were noted, suggesting that much of the copper pollutants is probably of automotive origin. The concentration of
lead was found to vary with housing age, and higher levels of contamination in the older neighborhoods were observed. This
result is probably ascribable to the accumulation of residues from leaded gasoline and lead-based paint in the past and the
use of coal fire for space heating in older houses. |
