“…Geochemical data for soil and groundwater calculated by Punia and Siddaiah [59] and Punia et al [33] were used for representing the spatial distribution of pollution indices. The extent of pollution load in soils is evaluated using Pollution Load Index (PLI) and in groundwater using Contamination Index (CI) and Index of Environmental Risk (I ER ).…”

“…Mining for petroleum products, stones and minerals is one of the known commercial activities in the semiarid region of India [30][31][32]. But the impact of these on the landscape patterns and soil and water contamination is the least studied [33]. Heavy metal contamination of soil and water due to mining is well reported by many researchers from different parts of the world [34,35].…”

Mines result in land use and land cover (LULC) change due to degradation of natural resources and establishment of new infrastructure for ore extraction and beneficiation. The present study was carried out to, with objectives, (1) characterize LULC change (from 1975 to 2017) in Khetri copper mine region, (2) spatial distribution of pollution indices and (3) spectral response of elemental concentration of soil and groundwater using Landstat and ASTER satellite data. The study was designed to fulfil the objectives and for the same NDVI values were calculated for LULC classification and generated maps were analyzed for landscape pattern. Spatial distribution of pollution indices calculated using geochemical data of soil and groundwater was plotted to understand the impact of contamination on landscape pattern. The correlation of spectral response of Landstat bands with heavy metals concentration was plotted to assess their possible use in quantification of heavy metals. Results show constant increase in settlements, mines and open area while vegetation cover has decreased. Landscape and class level metrics (number of patch, patch density, aggregation index and landscape shape index) indicate increase in the fragmentation of landscape in recent years. Shannon’s Evenness Index indicates increase in uniformity in landscape and it is attributed to loss of vegetation and agriculture patches. Pollution indices, Pollution Load Index for soil is high near the overburden materials and Index of Environmental Risk (IER) and Contamination Index for ground water is high near abandoned mines. Spectral bands 5 and 6 (SWIR 1) show significant negative correlation, and 9 (Cirrus) shows significant positive correlation with metal concentration in soil and water suggesting the possible use of remote sensing in assessment of metal concentration at ground level. Thus, it can be concluded that mines significantly influence the landscape pattern and remote sensing could be used for the assessment and predication of heavy metal contamination at broader scale in a cost-effective way.

Cd and Pb in farmland topsoil are controlled by many factors. To identify the source of potential toxic metals in the farmland topsoil around Mianyuan River, the chemical analysis and multivariate statistical analysis are performed in this study. The results indicate the following: (1) The concentration of Cd and Pb in soil exceed the background value of Chinese soil elements. (2) Cd is significantly enriched in the whole region and Pb is locally enriched, both of them are more or less influenced by human activities. (3) The contents of Cd and Pb increase significantly following the flow direction of river. (4) Pb isotope analysis indicates that the main source of Pb in the soil include the air dust, coal and phosphate plant, and the contribution of them decreases successively. (5) Linear correlation analysis and principal component analysis show that the main sources of Cd in the soil are mining phosphate rock, air dust, phosphate plant and coal mining.

“…pH, particle size, and temperature also control the leaching of heavy metals from tailings [15]. Additionally, coarser grain size of tailings indicates less extraction efficiency and high toxicity of tailings [5]. Tailings are source of heavy-metal contamination for soil and water resources through leaching and transportation process, as shown in Fig.…”

A review is designed to innovate a sustainable solution for the treatment of mine tailings using bioremediation and phytoremediation. It emphasizes on achieving the geochemical stability of tailings through the establishment of microbes or plants. It highlights the gaps in achieving the geochemical stability of tailings. Lack of nutrients and low pH discourage the survival of microorganisms and the growth of plants on tailings. Treatment of tailings with agricultural waste (wheat and mustard stalks) would nourish tailings which promote the growth of microorganism and plants. Application of agricultural waste in remediation process is cost-effective. The role of microorganisms such as cyanobacteria, fungi, and algae are well known for mineralogical transformation. Microorganism converts unavailable fraction of nutrient into available form and important initiative to drive tailings towards natural soil. It would support the growth of plants on tailings to achieve successful phytoremediation. Biofuel generation from tailings through high lipid and protein producing plants is important for sustainable development. Phytoremediation will reduce the environmental impact caused by mine tailings. For phytoremediation, use of biofuel producing plants, i.e., Jatropha curcus and Brassica juncea, is recommended.
