Abstract

Heavy metal concentrations in roadside dusts are increasingly becoming of health concern. Street dust samples and leaf deposited dust samples were collected from all the sites and analysed for Cu, Ni, Pb and Zn from five major roadways in Anand city, also known as milk capital of India .Metal concentrations in such dusts from five major roadways indicated that roadside dust contained elevated levels of heavy metals. Cu concentration ranged from 52-130 mg/kg; Ni from 57-71 mg/kg, Pb from 66- 105 mg/kg and Zn from 44- 93 mg/kg in street dust samples. Dust deposited on the leaves of four roadside plants common to the region viz. Alstonia scholaris, Ficus bengalensis, Morus alba, and Polyalthia longifolia, also had elevated levels of the same metals indicating a common anthropogenic source. The most likely source for the contamination of theses dusts was vehicle emissions supplemented by local industrial activities. PCA and correlation coefficient analysis also supported this fact
