Concentrations of Cu, Zn, Mn, Fe, Cd, Hg and As in muscle tissue of fish species collected from North East coast of India were determined. The bioaccumulation of Fe, Zn, Cu and Mn was predominant followed by As, Hg and Cd in muscle tissue of coastal fishes. The concentration range of Cu, Zn, Mn, Fe, Cd, Hg and As in fishes was 0.5-28.2, 3.0-99.1, 0.5-12.0,(More)
Preliminary analysis was performed to assess human health risks of exposure to 16 polycyclic aromatic hydrocarbons (PAHs) by way of inhalation by children and adults living in urban area of Amritsar, Punjab, India. In particular, the United States Environmental Protection Agency's (USEPA's) 16 priority PAH compounds were analyzed in air particulate matter(More)
Distribution of polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs) in urban soils, and their risk for humans was evaluated and presented in this article. The average concentration of ∑16PAHs, ∑carcinogenic PAHs, ∑28PCBs and ∑dioxin-like PCBs was 631.6 ± 244.5 μg kg(-1), 568.8 ± 238.8 μg kg(-1), 11.57 ± 2.00 μg kg(-1) and 2.58 ±(More)
Heavy metals i.e. Copper (Cu), Zinc (Zn), Manganese (Mn), Iron (Fe), Cadmium (Cd), Nickel (Ni), Mercury (Hg) and Arsenic (As) were analyzed in 35 samples of the fish muscle, from East Kolkata Wetlands (EKW). The concentration of heavy metals was in order of, Fe > Zn > Cu > Mn > Ni > As > Hg > Cd. The essential metals, such as iron, zinc, copper and(More)
A preliminary assessment of levels of polychlorinated biphenyls (PCBs) in surface waters was carried out and discussed in this paper. Total concentrations of ∑PCBs ranged between 1.03-21.79 ng L with the mean and median value of 12.91ng L and 11.26 ng L (±1.61 ng L), respectively. Average concentration of twelve WHO’s dioxin like-PCBs (DL-PCBs) was(More)

Persistent organic pollutants (POPs) like organochlorine pesticides (OCPs), polychlorinated biphenyles (PCBs) and polyaromatic hydrocarbons (PAHs) are discharged in surface water by various point and nonpoint sources thereby degrading the functioning of the ecosystem and threatening human health. Chlorinated pesticides such as Hexachlorocyclohexane (HCHs)(More)
Polychlorinated biphenyls (PCBs) were quantified in settled dust collected from informal electronic waste (e-waste) recycling workshops and nearby highways in the urban centers and roadside dust from the suburban industrial belt of Chennai city in India. Further dust samples were subjected to a high resolution field emission scanning electron microscope(More)
A simple method of extraction and determination of sixteen priority polycyclic aromatic hydrocarbons (PAHs) from waste water and sediment using high performance liquid chromatography (HPLC) has been validated with limits of detection (LOD) and limits of quantification (LOQ), method recovery and reproducibility and other factors. HPLC parameters, such as(More)
BACKGROUND Polychlorinated biphenyls (PCBs) have never been produced in India, but were used in industrial applications. PCBs have been detected in environmental samples since 1966, and their sources in soils come from depositions of industrial applications, incinerators and biomass combustions. PCBs adsorb to soil particles and persist for long time due to(More)
