Title

A REVIEW ON CONTAMINATION OF HEAVY METAL IN ROAD DUST COLLECTED FROM HEAVY TRAFFIC AREAS

Abstract

Road traffic is one of the main sources of emission of heavy metals into the environment. Road traffic involves various potential sources of metals through combustion products from fuel and oil, wear products from tyres, brake linings, bearings and clutches, corrosion products of vehicle components and road construction material. The number of vehicles in operation increasing year by year and lengthening of trips have resulted in the emissions of larger amount of metals originating from brake, tire, and road wear. Zn is the most abundant heavy metal from tire wear. Metal containing aerosols released from vehicular exhaust and non-exhaust emissions may lead high accumulation of heavy metals such as Pd, Cd, Ni, Cu and Zn and mixed with road dust. Vehicle brakes release a significant amount of heavy metals in the form of wear particles. One of the most dangerous elements contained in brake pads is copper. Zn is the most abundant heavy metal from tire wear. Its high concentration resulted from the addition of ZnS to the tire during vulcanization. The greatest Zn emission from tire occurs through abrasion in the form of tire dust during acceleration, braking, and concerning. Asphalt and sand paper like effects are significant sources of Ni in road dust. Concentration of Ni and Zn in road bitumen were higher than in raw bitumen therefore the heavy metal concentrations in road dust are significantly affected by vehicle operation and road abrasion.

Key Words

vehicle, copper, zinc, heavy metals.
