Characterization of soil heavy metal contamination and potential health risk in metropolitan region of northern China

On the basis of investigation of specific heavy metals contaminated site, use compound heavy metal hazard quotients to do a assessment for potential health risk. The primarily detected excessive heavy metals are Zn, Gr, Cu and Hg. Results indicate that: in the surface (0~30 cm) and subsurface (30~70 cm), the compound heavy metal hazard quotients of sampling point 7#, 12#, 13# 6#, 7#, 12#, and 13# are greater than 1, and soil exists heavy metal contamination; in 70cm~100cm soil layer, the hazard quotients of all monitoring points are less than 1, therefore in these layers soil is not contaminated, and there are no need for remediation. The result reflects compound heavy metal contamination directly, and provides a reference for later remediation work.

An investigation of the soil quality in the centre of Belgrade was per- formed to define how seriously the soil is polluted. On the basis of the heavy metal content (Zn, Cd, Pb, Co, Ni, Cu, Cr and Mn), the potential health risk assessment calculated for a lifetime of exposure (ingestion and inhalation), based on the USEPA model, was determined as the cumulative carcinogenic and non-carcinogenic risk for children and adults. The study proved that soil contamination in Belgrade is not insignificant; risk assessment indicated that the carcinogenic risk is completely insignificant but the cumulative non-carcinogenic risk tends to became significant, mainly for children, since it approaches unacceptable values. There is no particularly dangerous single heavy metal, but their cumulative effect, expressed as Child Soil Ingestion Hazardous Index, is for concern.

Rice is one of the major crops as well as the staple food in Malaysia. However, historical mining activity has raised a concern regarding heavy metal contamination in paddy plants, especially in Perak, a state with major tin mining during the late nineteenth century. Therefore, the objective of this study is to investigate the heavy metals (As, Cd, Pb, Cu, Cr) contamination in paddy soils and paddy plants in three districts in Perak. The content of heavy metals was determined using ICP-MS, while the absorption and transferability of heavy metals in the paddy plants were investigated through enrichment (EF) and translocation (TF) factors. Principal component analysis (PCA) was employed to recognize the pattern of heavy metal contaminations in different sampling areas. Health risk assessment was performed through calculation of various indices. The quantification results showed that root contained highest concentration of the studied heavy metals, with As exhibiting the highest concentration. The EF results revealed the accumulation of As, Cu, and Cr in the rice grains while PCA showed the different compositional pattern in the different sampling areas. The health risk assessment disclosed both noncarcinogenic and carcinogenic risks in the local adults and children. Overall, findings from this study show that heavy metal contamination poses potential health risks to the residents and control measure is required.

Potential Health Risk

Leafy vegetables and tubers contaminated by heavy metals will cause potential health risk to human beings. An analysis was carried out to study the heavy metal contamination in tubers and leafy vegetables at Kottayam district, Kerala. The results indicated that higher levels of lead were recorded in all of the samples analyzed when compared to the WHO permissible limits (0.1 mg/kg) for tubers and leafy vegetables, except in Colocasia esculenta (L.) Schott., collected from Erattupetta market. Cadmium content was higher in both the tubers and leafy vegetables collected from Changanacherry market. Therefore, regular assessment of the accumulation of heavy metals in leafy vegetables and tubers is the need of the era.
