Probabilistic health risk assessment was conducted for metal exposure through groundwater in mining areas of Singhbhum Copper Belt, India. The concentrations metals showed notable spatial variation exceeding drinking water standards at some the locations. Hazard Quotient revealed that chronic risks to local population were largely contributed by Mn, Co and As. 95th percentiles Index (HI) calculated using Monte Carlo simulations HI male, female child populations 2.87, 2.54 4.57 pre-monsoon,...
This study assessed the concentration of Al, As, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, Se, and Zn in commonly grown vegetables collected from Gaya district Bihar. Metals were determined using Inductively Coupled Plasma Mass Spectrometry following sample preparation digestion. Pb exceeded maximum allowable Food Agricultural Organization some vegetable samples. Non-carcinogenic human health risk assessment due to ingestion was estimated Hazard Quotient (HQ) Index (HI) which revealed that...
AbstractFive fish species and one shrimp from the Subarnarekha river were analyzed for heavy metals using inductively coupled plasma-mass spectrometry. The geometric mean concentration of As, Cd, Cu, Fe, Pb, Ni, Zn, Cr, Co, Sr all samples was found to be 0.248, 0.031, 5.16, 104.9, 0.121, 4.68, 52.2, 0.784, 0.207, 42.86 mg kg−1fresh, respectively. concentrations in exceed limits Indian FAO standards food Zn many samples. target hazard quotient (THQ) values 10 below samples; however, maximum...
Metal contamination was studied in locally rearing chicken and eggs the environs of mining areas Singhbhum copper belt. Concentrations metals were below Indian standards except for Cu, Ni Zn case at some locations. Estimated daily intake (EDI) target hazard quotient (THQ) suggested that did not pose risk individually. However, considering geometric mean metals, index (HI) above unity. Pb Co key components contributing to a potential noncarcinogenic risk. The HI varied from 0.62 1.66 among...
The concentrations of metals were determined seasonally to assess the probable risk on local population due ingestion via groundwater in an iron mining impacted area Jharkhand India. results depicted significant spatial and temporal variation concentration with highest values during pre-monsoon season locations active activities. Fe Mn exceeded drinking water quality standards about 75% samples considering all seasons. can be ascribed both geogenic sources anthropogenic causes as from...
Risk characterization of agricultural soils in the mining areas Singhbhum copper belt was done by determining total concentrations metals using inductively coupled plasma-mass spectrometry and assessing potential ecological human health risks. The were above average shale values for most metals. Principal component analysis showed anthropogenic contributions Cu, Ni, Co, Mn, Pb, Cr soils. Ecological risk assessment revealed that 50% soil samples at moderate to very high risk. Health risks...
Groundwater forms the major source of drinking water worldwide; however, its quality has been compromised due to various human activities. The contamination groundwater with metals have increased health risk consumers. In pursuit assessment and apportionment studies Naini Industrial Area, Prayagraj, Uttar Pradesh, India; samples (n = 60) were collected from distinct sampling locations spanning study area. Inductively coupled plasma-mass spectrometry (ICP-MS) was employed analyse...
The study represents the first systematic risk assessment in East Singhbhum district, Jharkhand, India for safety of groundwater drinking purpose with respect to metal(loid)s. district is known its mining and related activities. results demonstrated that concentrations metal(loid)s showed significant spatial variation Al, Mn, Fe, Ni Zn exceeding water standards. Principal component analysis resulted extraction four factors explaining 76.3% data variability. extracted principal components...
A new heavy metal pollution index (HMI) has been proposed for ranking noncarcinogenic in vegetable, rice, and milk. HMI comprises a pair of one positive (Pqi) negative (Nqi). Pqi represents metals present above the maximum allowable concentration, while Nqi corresponds to those below. Higher Pqi, greater is pollution. In case two similar food items have same or close decides relative degree contamination; lower Nqi, lesser Three different databases 12 57 vegetable samples (15 species), 14...
Groundwater quality was investigated for fluoride and nitrate contamination in the mica mining areas of Jharkhand with special emphasis on seasonal fluctuation, source apportionment human health risk assessment. Samples were collected from thirty-seven locations a basis. The results indicated 31% 32% samples groundwater to exceed Indian drinking water standards F– NO3–, respectively. Marked variation observed concentration NO3– highest levels monsoon season; however, fluctuation...
