ABSTRACT

 

This paper examines the significant differences in seasonal variations of air pollutants concentrations at industrial area of Visakhapatnam, Andhra Pradesh, India during March 2011 to February 2012 PM2.5, PM10, sulphur dioxide (SO2) and oxides of nitrogen (NOX) were collected over six (6) sites in Visakhapatnam. First sampling station location at Coromandal fertilizers, second sampling station location at Hindustan petroleum chemicals Ltd., third sampling station location at Hindustan Polymerisation, fourth sampling station location at Hindustan zinc, fifth sampling station location at Vizag Steel plant and sixth sampling station location at Hindustan ship yard. All the sampling stations selected are located in industrial areas. Meteorological parameters like temperature, relative humidity, wind speed, wind direction and rain fall were also recorded simultaneously during the sampling period. Monthly and seasonal variation of these pollutions have been observed and recorded. The annual average and range values have also been calculated. It has been observed that the concentrations of the pollutants are high in winter in comparison to the summer or the monsoon and post monsoon seasons. In the present study, it was noticed that the PM2.5 and PM10 levels at all selected sites exceeds the prescribed limits as stipulated by Central Pollution Control Board (CPCB) New Delhi. Apart from this the SO2 and NOX levels in industrial areas remain under prescribed limits of CPCB.
