Abstract
The carbon monoxide (CO) is a vital criterion of pollutants, universal in environment. It generally produces due to incomplete combustion of fuels. Roughly, 80-90% of absorbed CO binds with hemoglobin to form Carboxy hemoglobin (COHb). The intimacy of hemoglobin with carbon monoxide is 200-250 times more than oxygen. The effect of CO poisoning on human health are headache, nausea to the loss of attentiveness and collapse, if the exposures are prolonged and with high concentration. The ambient CO exposure may affect various people such as drivers, traffic polices, street sellers, parking servants, pedestrians and cyclists [4]. Ahmadabad has become a mega city. In Ahmedabad, the rapid population growth rate and vehicular growth rate cause serious traffic congestion on streets and roads during peak hours leads to air pollution. Carbon Monoxide concentration is measured at high vehicular traffic junction in Ahmedabad city by using Carbon monoxide analyzer. CO Concentration is measured at 1.5 m height during the 10 AM to 7 PM of every 15 minutes. The CO investigation occurred during 21st April to 19th May 2015. The fifteen heavy traffic junctions had been selected in Ahmedabad city. Out of 15 traffic junctions, at 13 traffic junctions, CO concentration exceeds the one hour National Ambient Air Quality Standards (NAAQS) in peak hours due to heavy traffic of school time and office time and cumulate 8 hrs CO concentration exceeds the NAAQS at nine traffic junctions out of total 15 selected traffic junctions. Estimated %COHb is not more than 1%, so it is not contributed to any serious health effect.
