Ambient air quality monitoring in visakhapatnam bowl area
The present scrutiny was carried out to know the significance of air pollutant concentrations in Visakhapatnam bowl area. SPM, RSPM, oxides of nitrogen (NOX) and sulphur dioxide (SO2), carbon monoxide (CO) collected in eight sites of Visakhapatnam. The locations of sampling stations are in muvvalavanipalem, kancharapalem, naval armament depot, nathayapalem, malkapuram, scindia, one town and jagadamba. The average and range values have also been calculated. It has been observed that the concentrations of the pollutants are high in winter in contrast to the summer season. In the present study, it was perceived that almost all the sites showed SPM and RSPM levels exceeding the anticipated limits as stipulated by Central Pollution Control Board (CPCB) New Delhi. Apart from this the SO2, NOX, and CO levels in bowl area were under permissible limits of CPCB.
