“…It seems a simple process; however the scale at which it is performed is giant, often-reaching tons per hour. This extraction generates a huge amount of tailings and in general, devastates the flora and fauna of the place where it is extracted (Santos, et al, 2022), (Longhini, et al, 2022). In general, the ores are often broken down, until they reach approximately two centimeters in diameter to be separated and washed.…”

“…Then comes the question of chemicals used in the washing of minerals, often these products are extremely toxic and rich in heavy metals, such as Mercury (Stace, 2022). According to Brazilian legislation, all water used in the extraction should be stored and recycled (Santos, et al, 2022), (Longhini, et al, 2022). Thus, to lessen the environmental impact caused by extraction and separation, all the tailing obtained is often stored.…”

“…When the activities are not conducted in the ideal way, several environmental problems can occur, among them: serious problems of contamination of water resources, pollution, soil contamination, air pollution, forests degradation, disturbances to the local population, alteration of local geology, damaging of fauna and flora, contamination with heavy metals (Santos, et al, 2022), (Longhini, et al, 2022).…”

“…Another serious risk that can occur due to mining is a dam break (Conceição, Lima, 2022), (Santos, et al, 2022), (Longhini, et al, 2022). Brazil experienced one of the largest accidents in the world and a serious environmental crime in 2019, when a mining tailings dam broke down in the state of Minas Gerais.…”

“…Islam and Weil [ 16 ] found that land use changes, such as forest degradation and soil cultivation, contributed to soil mechanical composition changing, and some soil chemical indexes content decreased, such as N and microbial biomass C. Their results suggested that land use changes can affect plants, land, and water provision, diminishing soil quality and causing soil contamination. In recent years, more and more studies have focused on assessing soil quality in single land use such as mining area [ 17 ], wetland [ 18 ], afforestation [ 19 ], and cropland [ 20 ], but few researchers have focused on different land uses in one study area. Therefore, assessing soil quality under different land uses is extremely important, especially in red soil areas.…”

The influences of different land uses associated with human activities on soil quality and the redistribution of heavy metal in soil have been widely concerned. Surface soil samples were obtained to assess comprehensive soil quality in a typical red soil region of southern China, combining the heavy metal pollution evaluation with fertility evaluation. It can be learned from the results that the overall level of soil fertility was at medium and lower level, and soil heavy metal pollution risk in the study area in a few regions had reached warning line and slight pollution line, and there was a risk of potential pollution. TOPSIS evaluation results showed that the comprehensive soil quality was mainly good quality and moderate quality, accounting for 31.7% and 29.0% of the total land area, respectively. Positive matrix factorization (PMF) model results showed that transportation source contributes a lot in terms of Cd and Pb. As for Cr, natural source contributes 53.8%. In terms of Cu and Zn, agriculture source contributes 50.7% and 38.7%, respectively. In a word, the comprehensive soil quality assessment in red soil region of southern China provides an important basis for the scientific management and sustainable utilization of soil resources.

The coast of Espírito Santo state (Southeast Brazil) is recognized for its environmental arsenic (As) enrichment and, over the years, mining operations have potentialized it. We aimed to evaluate the effect of Rio Doce discharge on As inputs and the role of iron ore tailings from the Fundão dam disaster in enhancing As contamination in the marine sediment. Two scenarios were evaluated: Predisaster and Postdisaster; dry and wet conditions were considered in each period. High As concentrations were found in the Predisaster (28.44 ± 13.53 µg g−1), but a significant increase in As was remarkable during the Postdisaster in the wet season, one year after the disaster (maximum of 58.39 µg g−1; geoaccumulation index (Igeo) Class 3, moderately severe pollution). On that occasion, iron (Fe) oxy‐hydroxides from tailings were remobilized from the Rio Doce channel and deposited on the continental shelf bottom. Therefore, chemical interactions among Fe, As, and carbonates were enhanced, resulting in As and Fe coprecipitation and the trapping by carbonate adsorption. Rio Doce discharge seems to be the main factor in As inputs to the inner continental shelf when flooding do not occur previously in samplings, which allows further dispersion of contaminants, although this hypothesis should be tested further.
