Abstract
ABSTRACT Risk characterization of agricultural soils in the mining areas of Singhbhum copper belt was done by determining the total concentrations of metals using inductively coupled plasma-mass spectrometry and assessing the potential ecological and human health risks. The concentrations were above the average shale values for most of the metals. Principal component analysis showed anthropogenic contributions of Cu, Ni, Co, Mn, Pb, and Cr in the soils. Ecological risk assessment revealed that 50% of the soil samples were at moderate to very high ecological risk. Health risks for adults and children were calculated using hazard quotients (HQs), hazard index (HI), and Cancer risks for the oral, dermal, and inhalation pathways. The HQs for all the metals except As and Co were below 1, which suggested that non-carcinogenic risks due to metal exposure through soils were within the safe limit. However, considering all the metals and pathways, the HI for adults and children was 0.71 and 5.61, respectively, suggesting appreciable risk to local residents. The carcinogenic risks due to As and Cr in the soils were within the acceptable value of 1E–04. For both carcinogenic and non-carcinogenic risks, oral ingestion appeared to be the primary pathway followed by dermal and inhalation pathways.
期刊介绍:
Human and Ecological Risk Assessment provides a resource for professionals researching and assessing environmental hazards to both humans and ecological systems. The editors expect papers published to be original, of sound science, purposeful for risk analysis (assessment, communication, management) and related areas, well written (in English), and a contribution to the scientific literature.
The journal''s emphasis is on publication of papers that contribute to improvements in human and ecological health. The journal is an international, fully peer-reviewed publication that publishes eight issues annually. The journal''s scope includes scientific and technical information and critical analysis in the following areas:
-Quantitative Risk Assessment-
Comparative Risk Assessment-
Integrated Human & Ecological Risk Assessment-
Risk Assessment Applications to Human & Ecosystems Health-
Exposure Assessment-
Environmental Fate Assessment-
Multi-Media Assessment-
Hazard Assessment-
Environmental Epidemiology-
Statistical Models and Methods-
Methods Development/Improvement-
Toxicokinetics Modeling-
Animal to Human Extrapolation-
Risk Perception/Communication-
Risk Management-
Regulatory Issues
