Organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs) were determined in agricultural soils from the northern states of India. The average concentration OCPs was 37.67 ± 0.33 ng/g (dry weight - DW) while HCHs alone accounted for 93% followed by DDT (4.27%) endosulphan (2.51%). α/γ ratio HCH (< 0.01-8.64) reflects use technical as well lindane formulations. p,p'-DDT/p,p'-DDE (0.16) o,p'-DDT/p,p'-DDT 0.01) indicates contamination with past DDT. mean concentrations dieldrin 0.95...

Concentrations of trace elements were measured in water (Cu, Zn, Fe, Pb, Mn, and Al), sediment (Cr, Cu, Ni, Al, Co), muscle tissue nine selected fish species Mn) collected from eastern Kolkata (India) estuarine-sewage fed ponds. In water, existed particulate phase (60–80%) with Fe as the predominant element followed by Al > Mn Zn Pb Cu. The partitioning coefficients (Kd ) are low fairly stable. Pearson product moment correlation among dissolved column was calculated most correlated well (p ≤...

Kolkata wetlands are the largest sewage fed in world. They have been used for aquaculture since 1960. Geochemical distribution of heavy metals (Cr, Cu, Mn, Fe, Zn, Pb, Ni and Al) has studied surface sediments using single sequential extractions techniques. The metal concentrations were following order: Fe>Al> Mn>Zn>Cu> Pb>Cr> Ni, average 29 μg g−1, 54 328 32747 169 38 25 g−1 23371 dry weights Cr, Al, respectively. Water-soluble percentages trace elements quite low (<0.01–3.75%) but presence...

Polychlorinated biphenyls (PCBs), hexachlorocyclohexane (HCH) and dichlorodiphenyltrichloroethane (DDT) are toxic, persistent bioaccumulative long-range atmospheric transport pollutants. These transported worldwide affecting remote regions far from their original sources, can transfer into food webs with a wide range of acute chronic health effects. India ratified the Stockholm Convention intention reducing eliminating organic pollutants (POPs), encouraged support research on POPs. Despite...

This article deals with the distribution, composition profiles, and possible sources of sixteen priority polycyclic aromatic hydrocarbons (PAHs) in residential soils from Korba district Chhattisgarh State, India. Sixteen PAHs were analyzed after ultrasonic extraction, silica gel column chromatographic cleanup, quantitation was performed using HPLC-DAD. The concentrations ∑16PAHs within acceptable limits soil quality guidelines study area got classified as weakly contaminated. concentration...

Polychlorinated biphenyls (PCBs) have never been produced in India, but were used industrial applications. PCBs detected environmental samples since 1966, and their sources soils come from depositions of applications, incinerators biomass combustions. adsorb to soil particles persist for long time due properties. Their close proximity may also lead human exposure through ingestion, inhalation, dermal contact, exert neurotoxic, mutagenic carcinogenic health effects.Residential Korba, was...

Dichlorodiphenyltrichloroethane (DDT), hexachlorocyclohexane (HCH), and their isomers' levels in residential soils were determined for the assessment of health risk Korba, India. Observed concentrations total HCH DDT more or less comparable with other parts India world. ΣHCH ΣDDT ranged between 0.9–20 μg kg−1 2–315 kg−1, respectively, which lower than recommended soil quality guidelines indicating low ecotoxicological risk. Carcinogenic non-carcinogenic impacts on human populations through...

ABSTRACT The River Yamuna originates from the Yamunotri glacier of Himalayas and travels 22 km in Delhi region. river is used for various purposes including drinking water supply. Twenty-eight polychlorinated biphenyls (PCBs) congeners were measured bank sediments along river, their ecotoxicological risk was evaluated. Concentrations ∑28PCBs varied 0.20–21.16 ng g−1 (dry wt.) with mean median values 6.63 5.84 (±0.69 g−1), respectively. concentration 12 dl-PCBs concentrations 0.04–2.86 a 1.04...

In this study, toxicity equivalents and health risks, based on concentration of 16 priority polycyclic aromatic hydrocarbons (PAHs) in urban residential soils were estimated for the human population Gwalior, India. Benzo(a)pyrene total potency (BaP TPE) assessment risk from direct contact with PAH-contaminated soil. Potential to contaminated groundwater leaching carcinogenic PAHs was assessed by estimating index additive cancer (IACR). On basis lifetime average daily intake through ingestion...

ABSTRACT Soils contaminated with toxic metals may be environmental hazards and sources of exposure to human population. in mining areas are among the most heavily by from activity. This study was focused on interest bioavailability studies using single sequential extraction methods. Results geochemical fractionation suggest that changes soil characteristics enhance mobilization Cu, Cr, Zn, Al. The observed metals' availability pattern Cr > Cu Zn However, total contents soils Al Cu. Risks...

Human Health Hazard due to Metal Uptake via Fish Consumption from Coastal and Fresh Water Waters in Eastern India Along the Bay of Bengal Concentrations copper, zinc, manganese, iron were determined muscle tissue coastal fish (Pumpus argentius, Tenulosa ilisha Rastrelliger kanagurta) fresh water (Hypophthalmichthys molithrix Cirhinnus mrigela) samples West Bengal, India, for assessing potential health risk human population. The concentrations Cu, Zn, Mn Fe muscles ranged between 0.79-4.0 mg...

Priority 16 polycyclic aromatic hydrocarbons were examined in the surface water from urbanized rivers and drains. The concentration Hindon River, Yamuna drains, respectively, varied 1.64 to 73.4, 1.98 93.0, 1.99 67.4 µg L−1. Total concentrations of PAHs winter 4.1, 2.9, 3.6 times higher than summer, respectively. Naphthalene, acenaphthylene, fluorene, (low molecular weight compounds) chrysene contributed 62.3% 74.4% 17.7% 24.8%, overall concentration. Their predominance suggested emissions...
