| Description |
Heavy metal concentrations in suspended particulate matter (SPM) were investigated for their
distribution and source in the atmosphere of coastal industrial town, Mithapur, Gujarat, India.
SPM, at 10 locations covering three seasons, were trapped on glass fibre filters using high
volume samplers and quantification of metals (Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn) was done
using Atomic Absorption Spectrometry employing HNO3 based wet digestion. Results show
relatively low concentrations of SPM (211.3 to 375.2 μg/m3) compared to National Ambient Air
Quality Standard (NAAQS), specified By Central Pollution Control Board (CPCB, India),
however, they were 2–3 times higher as compared to reference site. Among the heavy
metals Cr, Mn and Pb levels were low, while Ni and Cd found to be exceeding the USEPA
standards. The metal levels were also compared with those reported for other rural, coastal,
industrial and urban parts around the world. Enrichment Factor analysis indicated that Cd, Zn,
Cu, Pb and Ni were highly enriched relative to their crustal ratios (to Fe) and correspond to
substantial contribution of anthropogenic source of these metals. The source identification was
carried out by principal component analysis by applying a Varimax Rotated Component Matrix.
