A COMPARATIVE STUDY ON CONCENTRATION OF AIR POLLUTANTS AND RAINFALL OVER A COASTAL INDUSTRIAL AREA-A CASE STUDY

Abstract

Air pollution is the most commonly observed weather phenomena on urban and coastal industrial area. It has been play an important role on rainfall and climate variability in synoptic scale system. In the present study we have simulated the concentration of air pollutants and the rainfall data over the coastal city of Visakhapatnam (17°.68’N, 83°.21’E) by using histograms for this study. The observing time period is selected from (01-04-2012 to 01-03-2013). The air pollution data is collected from the area of CMQY RAMKY in the coastal industrial city of Visakhapatnam with the parameters SO2, NO2, CO2, NH3, PM 10 and PM2.5. This study is could predict the concentration of air pollutants and monthly variation in rainfall. . In the month of April the carbon monoxide (CO) values are very high when compared with the other pollutants, the highest value of CO is 600μg/m3 simultaneously the rainfall values are very low and the days of rainfall are low. While in the month of May, same pattern continues, the concentration of CO levels are very high than other pollutants. In the month June due to the onset of monsoon the concentration of pollutants are very low, the CO levels are very low compared to all other pollutants. The precipitation will wash out the heavy metals and trace gaseous particles
