Vulnerability Analysis of Ambient Air Quality in Industrial Zone

Air pollution is a major problem arising mainly from industrialization. Pollutants from industries are pumped directly into the atmosphere affecting the air quality. Since Visakhapatnam is an industrial hub,air pollution has become a major concern of distress. This study aims at, the assessment of ambient air pollution in and around Paravada region of industrial zone in Visakhapatnam. All the sampling stations have exceeded their permissible limit except Ravada. The standard value for particulate matter is 100 µg/m3 as referred by The revised National Ambient Air Quality Standards. The higher particulate matter pollution in the industrial area may be attributed to re-suspension of road dust, soil dust, automobile traffic and nearby industrial emissions. Ravada has reported lower values because it is at large distance from the industrial emissions and covered with rich vegetation.
