“…Previous studies have only focused on the contribution of HM sources to health risk. [28][29][30][31][32][33][34][35] However, exposure of both ecosystem and human beings to HMs can be harmful, 36,37 and thus evaluation of the contributions of different HM sources to ecological and human health risks is important but has rarely been explored in previous studies.…”

“…Correlations among these elements may reveal their similar sources, mutual dependence and common geochemical behavior in the studied soils (Lu et al, 2010). In contrast, a negative correlation between Mn and As, Pb and Mn, or Co and As reflects the opposite (Huang et al, 2019;Li et al, 2013;Sun et al, 2010). (Nour, 2019).…”

The presence of heavy metal(loid)s in soils from anthropogenic sources such as activities related to fossil fuel processing area could pose serious threat to the ecosystem and human health. However, risk factors depend on the source, distribution and human interaction with these contaminants and therefore case specific study is needed. In this study, using a geological information system (GIS) and 63 surface soil samples, we fully assessed 190 km2 area of a developing gas region in southern Iran. Mean concentration of manganese (Mn), zinc (Zn), copper (Cu), lead (Pb), total chromium (Cr), cobalt (Co), arsenic (As) and Cadmium (Cd) was 341.24, 129.40, 32.90, 26.85, 16.56, 7.52, 0.67 and 0.63 mg kg− 1, respectively, while As, Pb, Zn and Cd surpassed the local background level. Moreover, soil pollution was also assessed by the contamination factor (CF), geoaccumulation index (Igeo) and ecological risk factor (Er). Accordingly, these soils were classified as moderate to heavily polluted with As and Cd and un-polluted to slightly polluted by Cu, Zn, Pb, Mn, Cr and Co. The GIS and soil collection point tracing showed that the natural gas processing and residential activities were both significant pollution sources where ingestion was the main contributor to heavy metal(loid)s uptake. Overall, the hazardous index for noncarcinogenic health impact was < 1 indicating no risk; however, children were at greater risk than the adult. Total carcinogenic risk (TCR) index from As exceeded the maximum tolerable level (1.0E-04) for children and adults. Chromium Co, Cd and Pb exposure were within the acceptable limit in the adult group (TCR < 1.0E-06), but the Pb and Cr health-hazardous indices were higher than guideline value indicating the potential of cancer risk in children. Therefore, remedial actions are required to eliminate or reduce the toxicity of As, Cr and Pb attributed to the impacted soil.

“…The average concentration and EF of As in industrial land were significantly higher than those in other land use types, indicating that the industrial activities might be another source of As. Huang et al [62] and Khairy et al [63] reported that As was related to the emissions of industrial flue gas, sewage, and sludge. The average EF of Pb ranged from 0.93 to 1.21 under different land-use types and tended to accumulate in aquaculture land, industrial land, vegetable land, and cropland.…”

Coastal tidelands are important ecological habitat resources and valuable resources for agricultural land reclamation. Enrichment of potentially harmful elements (PHEs) in soil caused by anthropogenic activity is an important factor implicated in the ecological deterioration of soil in China. A total of 54 soil sample sites were selected from a 30-year reclaimed tideland and an adjoining coastal wetland. Descriptive and multivariate statistical analyses were performed to describe the enrichment, source, health risk status of eight PHEs (As, Co, Cr, Cu, Mn, Ni, Pb, and Zn) after long-term reclamation. Results indicated that after 30 years of reclamation, most soil PHEs are slightly enriched, whereas no serious threat of environmental pollution was observed. In the reclamation area, the enrichment of PHEs in the aquaculture land, industrial land, and cropland was relatively high compared with other land use types, such as tideland and halophyte land. The source analysis divided the PHEs into five categories: (1) Cu; (2) Co and Mn; (3) Cr; (4) As and Pb; (5) Zn and Ni. Cu was completely derived from natural parent materials and other elements were governed by both weathering of parent rock and human activities, including agricultural activities, industrial production, and transportation emissions. The health risk assessment showed that the soil PHEs potentially had no non-carcinogenic risk to the public, but there was an acceptable probability to have cancer due to Cr and As. Meanwhile, children are more susceptible to harm from the PHEs in soil than adults. According to the economic and social development situation in the coastal region, it is necessary to pay attention to the environmental threats of PHEs enrichment.
