Abstract: Ambient air pollution status in Dhanbad district is studied and presented in this article. The selection of Dhanbad is made considering its importance and the nature of activities taking place around the district. For the assessment of ambient air quality in Dhanbad, the following five locations were chosen: Main Gate of Indian School of Mines(ISM), Dhanbad: It is a site representing purely commercial activities and road traffic. Bankmore: It is one of the busiest marketing centres of the district and is surrounded by residential areas. All the vehicles going to Bokaro pass by this place and thus the traffic density is pretty high. Kusunda: It is a place 10.9 kilometres from Dhanbad Railway Station. It is just beside one of the coal mines, hence, all vehicles going to the mine passes through this place. Steel Gate: It consists of a small market. Trucks and other heavy vehicle are more frequent during night as this road connects to a highway. ISM Admin Block: It can be considered as a sensitive area since it is a very calm place where the usage of vehicles is minimum throughout the day. Monitoring of ambient air quality is done following the standard procedure prescribed in IS: 5182. In addition, the concentration of lead, zinc, cadmium, copper, manganese and iron metals in SPM is also monitored. The ambient air quality assessment was done in the month of June, 2009. The concentration of SPM was higher than the permissible limit in three locations namely ISM Main Gate, Bankmore and Steel Gate, while it was less than the permissible limit in other two locations, ISM Admin Block and Kusunda. Since the generation of SPM was mainly due to vehicular traffic it was expected to cross the limit in the above mentioned three locations as density of vehicular movement is very high. 2010 CAFET-INNOVA TECHNICAL SOCIETY.
