Airborne Cu and Zn at some urban sites in Pital Nagri (Moradabad), India.
Airborne concentrations of copper (Cu) and zinc (Zn) in suspended particulate matter (SPM) have been measured at three urban sites in Pital Nagri (brass city) of India over a period of one year, i.e., August 2006 to July 2007. Analysis of samples was carried out by the atomic absorption spectrophotometer. A comparison was made between the sites and concluded that the maximum concentrations of SPM (762 microgm(-3)), Cu (56.01 microgm(-3)) and Zn (72.15 microgm(-3)) were found at industrial site and minimum at residential (200 microgm(-3), 2.10 microgm(-3) and 1.65 microgm(-3)) site respectively. A seasonal variation in concentrations was also observed. In this paper, an attempt has been made to identify the various sources responsible for the high level of toxicity and it has been concluded that brass industries are mainly responsible for the enhanced concentration of these two metals.
