“…Other studies have shown that the addition of compost not only increases soil fertility and plant biomass but also reduces the concentration of trace elements in plant species grown in metal-contaminated mine soils [47]. Oyebamiji et al [48] reported the distribution of heavy metal such as, Pb, Zn, Cu, Ni, Cr, and Fe in active mining soils in southwestern Nigeria. Incorporation of compost provides benefits for remediating trace elements (Cu, Pb, Zn, and As) in polluted soil [49].…”

Opencast nickel mining is common in natural forests of Indonesia. However, rehabilitation of postmining degraded land is difficult. We investigated the effect of opencast nickel mining on soil chemical properties and the growth of two fast-growing tropical tree species, Falcataria moluccana and Albizia saman. Soil was collected from post-nickel mining land and a nearby natural forest. Soil pH, available phosphorus (P) concentration, total carbon (TC) and total nitrogen (TN) concentration, C/N ratio, cation exchange capacity (CEC), and exchangeable K, Na, Mg, Ca, Fe, and Ni concentrations were determined. Falcataria moluccana and A. saman were then grown in the collected soils for 15 weeks in a greenhouse. Shoot height and shoot and root dry weights of the seedlings were measured. The post--nickel mining soils TN, TC, available P, CEC, and exchangeable Ca and Na concentrations decreased by 98%, 93%, 11%, 62%, 85%, and 74%, respectively, in comparison with the natural forest soils. The pH of postmining soil was higher than natural forest soil. Shoot dry weight of F. moluccana seedlings grown in postmining soil was significantly ( P < 0.05 ) lower than that of seedlings grown in natural forest soil. However, there was no difference in shoot dry weight between A. saman seedlings grown in natural forest soil and postmining soil, as well as root dry weights of both species. The results indicate that opencast nickel mining decreased soil fertility, which subsequently inhibited the growth of F. moluccana and A. saman seedlings.

“…The heavy metal concentration in the sample is C n , while the metal concentration in the background sample is Bn. The factor 1.5 was created to investigate probable fluctuations in background levels for a certain metal in the environment (Oyebamiji et al, 2018;Princewill and Adanma, 2011).…”

This study was carried out to evaluate the ecological and health risks associated with metals in soils around major cement company in southern Nigeria. Twenty-one soil samples including a control sample were collected around the cement company. Metals such as Cd, As, Co, Cr, Cd, Pb, Ni, Fe, and Zn were analysed using Atomic Absorption Spectrometer (AAS). Results showed that the average concentration of Cu, Co, Cd, Cr, Ni, Pb, Zn is 7.95 mg/kg, 0.50 mg/kg, 3.00 mg/kg, 1.00 mg/kg, 0.95 mg/kg, 2.00 mg/kg and 6.80 mg/kg while the average concentration of Cu, Co, Cd, Cr, Ni, Pb, Zn around the cement production area is 6.30 mg/kg, 1.50 mg/kg, 1.75 mg/kg, 2.09 mg/kg, 2.62 mg/kg, 6.40 mg/kg and 3.58 mg/kg respectively. The concentration of metals in this area was lower than the recommended standards but higher than those in the background soil. Contamination assessment of metals in soils of Okpella area revealed that they pose a very high degree of pollution and deterioration of the environment. Furthermore, ecological risk assessment revealed that the metals pose medium ecological risks. Health risks assessment uncovered that children residing in this area are prone to non-carcinogenic health risks through dermal contact with Cobalt in contaminated soils of the area. The statistical evaluation showed that metals in the soils might have originated from related sources. It is recommended that proper environmental monitoring of the area be carried out reduce its impact on the health of the populace.

“…Although less studied, mining has been cited as a signi cant source of recalcitrant pollutants especially heavy metal(loid)s (Lin et al, 2005; J. . Globally, several studies have reported increased heavy metal concentrations and ecological risks in areas associated with mining activities (Ngole-Jeme and Fantke, 2017; Oyebamiji et al, 2018;Sungur et al, 2020).…”

A comprehensive study was conducted to explore the concentration and distribution of heavy metals in farm soils and river sediments around a gold mining area in Fiji with particular emphasis on ecological and human health risks. Representative samples were acquired from farm sites in Matanagata Village and the Nasivi river, both situated around the Vatukoula Gold Mine Limited (VGML), the largest operational gold mine in Fiji. Following aqua regia digestion and analysis by AAS, the average soil concentrations for Cu (110.4 mg kg− 1), Cr (136.2 mg kg− 1) and Cd (1.7 mg kg− 1), and sediment concentrations for Pb (69.31 mg kg− 1), Cd (1.82 mg kg− 1), Cu (88.95 mg kg− 1) and Cr (143.12 mg kg− 1) were found to exceed the recommended guideline values. Based on the geo–accumulation index (Igeo) and enrichments factor (EF), the farm soils were moderately contaminated with Cd while the sediments showed moderate to significant contamination with Pb, Ni and Cr. Ecological risk assessment confirmed moderate to considerable ecological risk in the metal–contaminated samples, with Cd and Pb generally presenting greater risk compared to other metals. Multivariate analyses including principal component analysis pointed to gold mining activities as a potential source for heavy metals in the area. Furthermore, human health risk assessment (HRA) indicated that while adults faced no significant carcinogenic or non–carcinogenic risks from metal exposure (HI < 1), children were at more risk from Co, Mn, Cr and Fe exposure, as well as potential carcinogenic risk from Cd (ILCR = 1.46E–04).
