Lead monitoring in air, soil and foliar deposits at Indore city with special reference to automobile pollution.

ABSTRACT

Ambient lead levels in air, soil and dust deposits on selected plant species at ten distinctly located sampling stations of Indore city are presented. The maximum lead level in air was recorded at Palasia, where the traffic density was found to be the highest. Out of the plant species studied, the maximum lead was recorded on Dalbergia sissoo leaves. A possible relationship between leaf morphology and dust accumulation tendency is also discussed.
