چکیده انگلیسی
Particulate polycyclic aromatic hydrocarbon (PAH) concentration was estimated during Integrated Campaign on Aerosol, Gases and Radiation Budget (ICARB-W) in winter (2008-2009) on board the Sagar Kanya over Bay of Bengal (BOB). The concentration of particulate PAH (Σ11 6.65 ± 2.86 ng/m3) over BOB ranged from 0.28 ng/m3 to 1.15 ng/m3. The concentration of middle and high molecular weight PAHs (4-6 rings), accounted for > 50% of total PAHs. Analysis of photochemical oxidation using ratios of BaA/Chy and BaP/BbF suggested the fresh release of air masses from local sources or from the nearest coastal areas of BOB. Principal component analysis (PCA) and correlation between tPAHs, nss-K+, nss-SO42 −, NO3−, organic carbon (OC) and elemental carbon (EC) suggested that motor vehicle emission, biomass burning and coal combustion may be the possible principal sources of PAHs over BOB during the study period.
