Abstract
Source apportionment study carried out using PMF (USEPA PMF5.0) receptor model identified six major sources at Jogannapalem and seven predominant sources at Parawada, which are contributing to collected PM. The two study locations share five common sources viz. crustal, sea salt spray, coal combustion, fuel oil combustion and metal industry. The other sources include biomass burning at Jogannapalem; road traffic and secondary aerosols at Parawada. At Jogannapalem, biomass burning (35%) is the predominant source, whereas coal combustion (22.6%) is dominating at Parawada. PMF factor profiles were observed to have similar elemental profiles obtained at different industrial locations of Visakhapatnam.
