Some gas pollutants i.e., amines, chlorine, hydrogen sulfide, sulfur dioxide and arsenic hydride were studied by collecting the air sample near the industrial areas through indicator tubes. Air sampleswere taken at the height of 1.5-1.6 meters from the ground and the distance of 100-200 meters from the manufacturing factory. Amines were the only gas pollutant found and in the range of 0.54-3.93 ppm which is below the threshold limit value (TLV). Many factors, i.e., wind speed, precipitation, atmospheric pressure, and temperature affect the gas pollutants concentration. The protein digesting/cracking and the decay of protein waste are found to be the major source for producing amine volatiles.
