The city is the head quarter of the Eastern Naval command of the Indian Navy. Its geographical location Eastern Ghats and the coast of the Bay of Bengal. Is the most populous city in the state with a population of 2 million as of 2011, making it the 14 in the country, it is the 9 metropolititan area in India. The industries and the commercial hub of the state. The city has many large industries such as The Hindustan petroleum refinery, Bharat heavy Plates and Vessels ltd., Coromandal Hindustan Shipyard etc. And industries. The sampling site was located within the steel plant. The sampling was carried out for 2 days in a week. The continous sampling was carried for 8 hours a day, using High Volume Air Sampler of model no HVAIR100, and the analysis was spectrophotometer.

Mise 1PG Environmental Engineering Course PDA College of Engineering, f Civil Engineering , India ABSTRACT The increase in the demand of steel has led increase in production of steel which results in the increase in the discharge of pollutant in the air. Which pollute the air causing harm to the comfort or health of humans and animals, or could damage plants and materials. This study process aims on monitoring the concentration of pollutants being expelled in the ambient air from the chimneys of vizag steel plant, which is situated in Visakhapatnam. The various air pollutants taken in consideration includes PM10, NOx and Sox. After analysis, the maximum concentration of PM10 is 135. 88µg/m3, NOx is 25.36 µg/m3, SOx is 17.69 µg/m3. The mean concentration of PM10 is 114.94µg/m3, NOx is 17.06 µg/m3, SOx is 13.00 µg/m3. Keywords: Ambient air, PM10, NOx, SOx I. INTRODUCTION Rapid industrialization & urbanization has resulted in the emergence of industrial centers that result in increase in pollution level of the air. In India, pollution has become a great topic of debate at all levels and especially the air pollution because of the enhanced anthropogenic activities Among the harmful chemical compounds, of fossils fuels burning puts into the atmosphere, are carbon dioxide (CO2), Carbon monoxide (CO), oxides of nitrogen (NOX), oxides of sulphur (SOx) and tiny solid particles including lead from gasoline additive called particulate. Some substances come from natural sources while others are caused by human activities. In the morden world, due to increase in demand of The increase in the demand of steel has led to the increase in production of steel which results in the increase in the discharge of pollutant in the air. Which pollute the air causing harm to the comfort or health of humans and animals, or could damage plants and steel for various infrastructure development has led to the increase in much more production of steel as a result there is an increase in gaseous pollutant in air.
