Soil contaminated with heavy metals from artisanal gold mining in Anka Local Government Area in Northwestern Nigeria was investigated to evaluate the human health risk as a result of heavy metals. Measured concentration of heavy metals and exposure parameters were used to estimate human carcinogenic and non-carcinogenic risk. geographic information system (GIS)-based Kriging method was utilized to create a prediction maps of human health risks and probability maps of heavy metals concentrations… Expand

Identifying sources and assessing potential risk of heavy metals in soils from direct exposure to children in a mine-impacted city, Changsha, China.
Results show that heavy metal contamination in Changsha may originate from coal usage and industrial activities, and suggest that not all sites within the study area may be suitable for housing or allotments without remediation. Expand
Spatial analysis of the risk to human health from exposure to arsenic contaminated groundwater: A kriging approach.
Two different kriging approaches are applied to carry out a spatial analysis of the health risk associated with ingesting As through the drinking of groundwater in the Lanyang Plain and the results show that the geographical distribution of unacceptable HQ zones is concentrated in the eastern part of the study area, which includes the high-population density townships.

Heavy Metals Speciation and Human Health Risk Assessment at an Illegal Gold Mining Site in Igun, Osun State, Nigeria.
Cancer risk and non-cancer risk (hazard index) assessment showed that arsenic poses a higher risk in adults and children compared to other metals through the dermal exposure route, indicating that these metals are strongly bound to the resistant components of the soil matrix. Expand
