Abstract
Concentrations of some potentially hazardous heavy metals such as Lead (Pb), Cadmium (Cd), Zinc (Zn), and Nickel (Ni) were investigated in particulates and road side surface dust in Bangkok Metropolitan Area. A total of 190 air samples and 270 surface dust samples were collected and analysed using Atomic Absorption Spectro-photometer. The analysis shows that the maximum concentration of these metals in the air is below Threshold Limit Values (TLV) and is dependent upon parameters such as precipitation, wind speed, traffic volume, and congestion. Automobiles are found major sources of these pollutants.
