“…Soil carbon is an important soil parameter as it improves soil physical and chemical properties and overall soil quality. Soil carbon exists in various forms that are functionally different and have contrasting residence times as reported by Prematuri et al [ 34 ]. The low C:N ratio is reflective of the poor carbon content obtained in the soil, which is obvious in mining soil as the degradation of organic matter increases with regular mining activity.…”

Background Mining for precious metals is detrimental to the composition of soil structure and microbial diversity distribution and is a health risk to human communities around the affected communities. This study was aimed at determining the physical and chemical characteristics and diversity of bacteria in the soil of local mining sites for biosorption of heavy metals. Results Results of physical and chemical characteristics showed mean pH values and percentage organic carbon to range from 7.1 to 8.2 and 0.18 to 1.12% respectively with statistical significance between sampling sites (P ≤ 0.05). Similarly, cation exchange capacity, electrical conductivity, moisture, total nitrogen, and carbon/nitrogen ratio (C:N) in the soil ranged between 1.52 to 3.57 cmol/kg, 0.15 to 0.32 ds/m, 0.14 to 0.82%, 0.10 to 0.28%, and 1.7 to 4.8 respectively. The highest heavy metal concentration of 59.01 ppm was recorded in soils obtained from site 3. The enumeration of viable aerobic bacteria recorded the highest mean count of 4.5 × 106 cfu/g observed at site 2 with statistical significance (P ≤ 0.05) between the sampled soils. Alcaligenes faecalis strain UBI, Aeromonas sp. strain UBI, Aeromonas sobria, and Leptothrix ginsengisoli that make up 11.2% of total identified bacteria were able to grow in higher amended concentrations of heavy metals. The evolutionary relationship showed the four heavy metal–tolerant bacteria identified belonged to the phylum Proteobacteria of class Betaproteobacteria in the order Burkholderiales. Heavy metal biosorption by the bacteria showed Alcaligenes faecalis strain UBI having the highest uptake capacity of 73.5% for Cu. Conclusion In conclusion, Alcaligenes faecalis strain UBI (MT107249) and Aeromonas sp. strain UBI (MT126242) identified in this study showed promising capability to withstand heavy metals and are good candidates in genetic modification for bioremediation.

“…The toxicological impacts of Ni on humans include allergic dermatitis, asthma, and mucosal irritation [61]. The amount of Ni in the soil samples may be related to its presence in iron ore limonite, which mostly contains 1.00-2.00% Ni or pentlandite as well as garnierite (mixture of Ni-rich natural silicates) [22]. The concentrations for zinc in the mining soil samples oscillate from 20.27 to 97.64 mg/kg d.w. At the mining site, MS1 which constituted 14.29% of the total mining soil sampled, the zinc content detected in it was higher than the average concentration and was three times higher than Zn levels in the other soil samples.…”

“…However, the concentrations for Zn detected in other farmland soil samples were four to eight times lower than the average shale concentration of Zn for sedimentary rock. The high concentration of Zn in the mining site MS1 and farmland FL1 may be attributed to its presence with minerals like hemimorphite (zinc silicate), smithsonite (zinc carbonate), and wurtzite (zinc sulfide) [22]. Even though animals and humans can control proportionally high levels of zinc, too much Zn may still result in serious health issues, for instance, skin irritations, anemia, stomach cramps nausea, etc.…”

“…Mining activities involving digging and braking rock materials often concentrate radionuclides to a level that may cause a risk to the environment and humans [14]. It has been stated that poisoning by substances associated with mining operations has been linked to increased cases of respiratory problems, miscarriages in women, kidney infection, cancer, and deaths in most inhabitants' communities where mining activities take place [14,[20][21][22][23].…”

Mining sectors in the developing world are located in villages, where farming is the prime source of income. This generates the likelihood of adverse spillovers to agriculturalists through rivalry for main inputs (i.e. land, labor, water, and environmental pollution). To explore this concern, gold mining sites on the Pra River of Ghana and nearby farmland soils were sampled and analyzed to evaluate the levels of potentially toxic metals (PTM) and naturally occurring radioactive elements (NORE) and appraise the potential ecological risk of PTM in soil samples. Cold vapor atomic fluorescence spectrometer was used to analyze the contents of total mercury (THg) while inductively coupled plasma-optical emission spectroscopy was used to determine the total concentrations of Ni, Cr, Pb, Co, Cu, Cd, Zn, and As. Instrumental Neutron Activation Analysis technique was used to detect the NORE concentrations in the soil samples. Geochemical indices were used to help evaluate the environmental risks. Toxic metals and radioactive elements concentrations in mining soil samples varied in the range: THg (0.37-0.59 mg/kg d.w.), As (4.68-19.69 mg/kg d.w.), Pb (6.67-23.02 mg/kg d.w.), Cd (0.103-0.315 mg/kg d.w.), Co (5.06-15.03 mg/kg d.w.), 97 mg/kg d.w.), Cu (15.43-38.05 mg/kg d.w.), mg/kg d.w.), Zn (20.27-97.64 mg/kg d.w.), Al (34,739.33-51,037.07 mg/kg d.w.), Th (77.97-136.10 mg/kg d.w.), and U (< 34.14-102.31 mg/ kg d.w.). The levels of PTM and NORE in farmland soil samples ranged from THg (0.09-0.49 mg/kg d.w.), As(0.45-7.01 mg/ kg d.w.), Pb (3.01-7.01 mg/kg d.w.), Cd (0.01-0.10 mg/kg d.w.), Co (3.12-8.65 mg/kg d.w.), mg/kg d.w.), Cu (8.83-18.07 mg/kg d.w.), Ni (8.12-16.08 mg/kg d.w.), Zn (9.63-42.33 mg/kg d.w.), Al (23,110.71 mg/kg d.w.), Th (< 47.17-57.061 mg/kg d.w.), and U (< 34.14-42.99 mg/kg d.w.). High levels of NORE, THg, and As were detected in some of the farmland sites. Radioactive elements were enriched in all the soil samples detected, while THg, As, Co and Zn were enriched in some of the soil samples analyzed. Mercury exhibited a moderate level of monomial ecological risk in some farmland soil samples while the other PTMs showed low risk in all farmland soil samples. This study has proved that farmland soils contain concentrations of U, Th, THg, and As that can harm the eco-agrosystem and these hazardous elements can be transferred to humans and animals through the food chain process. It is believed that mining activities on the river and phosphate fertilizer applications on farmlands are the major influence.

“…The potential mineral deposits comprise ferrum and associates (iron, nickel, mangan, cobalt, titanium, chromite, and molybdenum), precious metals (gold, silver, and platinum), base metals (tin, zinc, copper, lead, and mercury), and rare metals (bauxite and monazite) [5]. However, almost all of the mineral and coal resource deposits in Indonesia are located in tropical rainforest lands [6].…”

Tropical forests are among the most diverse ecosystems in the world, completed by huge biodiversity. An expansion in natural resource extraction through open-pit mining activities leads to increasing land and tropical forest degradation. Proper science-based practices are needed as an effort to reclaim their function. This paper summarizes the existing practice of coal mining, covering the regulatory aspects and their reclamation obligations, the practices of coal mining from various sites with different land characteristics, and the reclamation efforts of the post-mining landscapes in Indonesia. The regulations issued accommodate the difference between mining land inside the forest area and outside the forest area, especially in the aspect of the permit authority and in evaluating the success rate of reclamation. In coal-mining practices, this paper describes starting from land clearing activities and followed by storing soil layers and overburden materials. In this step, proper handling of potentially acid-forming materials is crucial to prevent acid mine drainage. At the reclamation stage, this paper sequentially presents research results and the field applications in rearranging the overburden and soil materials, controlling acid mine drainage and erosion, and managing the drainage system, settling ponds, and pit lakes. Many efforts to reclaim post-coal-mining lands and their success rate have been reported and highlighted. Several success stories describe that post-coal-mining lands can be returned to forests that provide ecosystem services and goods. A set of science-based best management practices for post-coal-mine reforestation is needed to develop to promote the success of forest reclamation and restoration in post-coal-mining lands through the planting of high-value hardwood trees, increasing trees’ survival rates and growth, and accelerating the establishment of forest habitat through the application of proper tree planting technique. The monitoring and evaluation aspect is also crucial, as corrective action may be taken considering the different success rates for different site characteristics.
