Identification of responsible sources of pollution using physical parameter particulate matter (PM)10 in a critically polluted area is discussed in this paper. Database was generated by Ambient Air Quality Monitoring (AAQM) with respect to PM10 and PM2.5 in 18 monitoring stations at Jharia coalfield as per the siting criteria (IS: 5182, Part XIV) during 2011 to 2012. Identification of the probable sources of PM10 was carried out through particle size, shape, morphology analysis (scanning electron microscopy (SEM)), suitable compounds (X-ray diffraction (XRD)) and elements (energy-dispersive spectroscopy (EDS)). Monitoring stations nearby opencast mine were affected by the big-sized and irregular-shaped particles; on the other hand, monitoring stations nearby city were affected by the small-sized and regular-shaped particles. In a city area, additional sources like diesel generator (DG) set, construction activities, coal burning, etc., were identified. Blistering effects were also observed in the particles from mine fire-affected areas. Using the X-ray diffraction technique, presence of FeS2, CuO, FeSO4 and CuSO4 compounds was observed, which indicates the effects of mine fire on particulate emission due to presence of SO4(2-) and S2- ions.

“…Shifts in peak positions, changes in intensities, and band areas of the infrared spectrum were exploited to get important structural and functional information about the studied tissues (Hayashi et al 2007). The observed peak positions of the spectra for the studied organs and their assignments according to the previous literature are presented in Table 1 (Palaniappan and Renju 2009, Senthil Kumar and Rajkumar 2014, Sivakumar et al 2014.…”

Contamination of aquatic ecosystems with toxic metals such as Cd 2+ and Pb 2+ is a serious issue in the industrialized world, which can affect freshwater fish even at low concentrations. The aim of the present study was to investigate the effect of Cd 2+ and Pb 2+ alone or in combination on the biochemical constituents of liver and muscle in Crucian carp using Fourier Transform Infrared Spectroscopy (FT-IR). Results from the spectral analysis revealed significant decline in protein and increase in lipids in the two tissues with marked effect caused by the combined exposure of Cd 2+ and Pb 2+ . In case of liver, alteration in the intensity and band area at amide I resulted in a differential response of structural protein for the exposed groups. Furthermore, a decrease in the α-helix and alterations in the nucleic acids content was also observed in both liver and muscle of the exposed fish. Moreover, biochemical alterations in the vital tissue of freshwater fish due to toxic contaminants can be used as a marker of environmental pollution with the help of FT-IR spectroscopy.
