“…Heavy metal contamination soil results in huge losses in the yield of economic crops, and the toxic elements enter the food chain and affect human health . Cadmium (Cd) is not biodegradable and is a very hazardous environment contaminative element that causes renal damage, osteoporosis, and even cancer .…”

Mulching with the straws of Trifolium repens, Conyza canadensis and Stellaria media increased the root, stem, leaf, shoot and whole‐plant biomasses of Cyphomandra betacea seedlings under cadmium (Cd) stress compared with the control, increased the chlorophyll a, chlorophyll b, total chlorophyll and carotinoid contents, and improved superoxide dismutase, peroxidase, and catalase activities. However, the straw of Eclipta prostrata decreased the biomass, photosynthetic pigment content and antioxidant enzyme activity of Cyphomandra betacea seedlings under Cd stress compared with the control. Mulching with the straws of Trifolium repens, Eclipta prostrate, and Stellaria media increased the Cd contents in roots, stems, leaves, and shoots of Cyphomandra betacea seedlings compared with control, while the straw of Conyza canadensis decreased the Cd content. Therefore, mulching with Conyza canadensis can promote the growth of Cyphomandra betacea seedlings, and decrease their Cd accumulation, which benefits the safe production of Cyphomandra betacea. © 2016 American Institute of Chemical Engineers Environ Prog, 36: 366–371, 2017

“…The negative impact of these mining activities in the surrounding areas is mainly due to the presence of a high number of cuts. These cuts often have negative effects on the natural vegetation they grow in, such as low pH, concentration of toxic metals, low water retention capacity and low plant nutrient levels (Nouri and Haddioui, 2016). Wildlife can be affected directly by toxins and indirectly by creating mutations in biotic and abiotic factors.…”

Mining is vital for human sustenance and a crucial sector in the state economy. However, its impacts on the environment and biodiversity cannot be underestimated. Which are potent to the attract government’s attention. Environment and wildlife are subject to the harmful impacts of mining and its related activities. In this study, districts, namely Mardan and Mohmand have been targeted with respect to mining impacts. The assessment was carried out on wildlife adversely affected by the mining sector. The fauna has been keenly observed to bring the calculated risks and threat perception of the regional wildlife. Total 9 species of mammals, 21 species of birds, were recorded in District Mardan. While in District Mohmand 2 species of mammals, 9 species of birds, and 4 species of reptiles were studied. The Study explored that mining primarily responsible for land degradation. Which lead to food and agriculture losses. Several other factors like blasting, pollution, hunting, deforestation, habitat loss was also observed. Deforestation surfaced one of the major causes for extinction of fauna in the said region. preemptive measures are needed to seize the man-made catastrophe.

“…Another endemic problem with abandoned and derelict mines is the generation of large-scale acidic waters containing elevated concentrations of metals and metalloids (Clarke 1995;Naidu et al 2013). The toxic metals can be dispersed in the vicinity of AML and accumulated in plant and animal bodies as a result of direct or indirect consumption (Nouri and Haddioui 2016). Typically, a mine degraded wasteland comprises of stripped areas (59 %), open-pit mines (20 %), tailing dams (13 %), waste tips (5 %), and land affected by mining subsidence (3 %) (Miao and Marrs 2000), but the spread of pollutants is continuous.…”

The lack of awareness for timely management of the environment surrounding a metal mine site results in several adverse consequences such as rampant business losses, abandoning the bread-earning mining industry, domestic instability and rise in ghost towns, increased environmental pollution, and indirect long-term impacts on the ecosystem. Although several abandoned mine lands (AMLs) exist globally, information on these derelict mines has not been consolidated in the literature. We present here the state-of-the-art on AMLs in major mining countries with emphasis on their impact towards soil health and biodiversity, remediation methods, and laws governing management of mined sites. While reclamation of metalliferous mines by phytoremediation is still a suitable option, there exist several limitations for its implementation. However, many issues of phytoremediation at the derelict mines can be resolved following phytostabilization, a technology that is effective also at the modern operational mine sites. The use of transgenic plant species in phytoremediation of metals in contaminated sites is also gaining momentum. In any case, monitoring and efficacy testing for bioremediation of mined sites is essential. The approaches for reclamation of metalliferous mines such as environmental awareness, effective planning and assessment of pre-and postmining activities, implementation of regulations, and a safe and good use of phytostabilizers among the native plants for revegetation and ecological restoration are discussed in detail in the present review. We also suggest the use of microbially-enhanced phytoremediation and nanotechnology for efficient reclamation of AMLs, and identify future work warranted in this area of research. Further, we believe that the integration of science of remediation with mining policies and regulations is a reliable option which when executed can virtually balance economic development and environmental destruction for safer future.
