“…Mohapatra & Kirpalani (2017) sugieren la implementación de embalses y/o estanques de tratamientos de los relaves en la minería del oro y su respectivo tratamiento con nanopartículas, antes de ser desechados para reducir la contaminación de las aguas superficiales y/o subterráneas (Liang et al, 2017). Se han encontrado concentraciones de metales pesados como Pb, Cd, Cu, Zn, As, Hg, Cr, Mn (manganeso), Ni (niquel), U (uranio) y 232 Th (torio), medidos en mg•kg -1 , en una mina de U en China que resultaron en concentraciones significativas en los alrededores de las zonas de cultivo, según el Índice de Concentración de Contaminación (PLI) y el ARC-GIS satelital (de Lucia Lobo et al, 2017).…”

El presente documento tiene como objetivo discutir y analizar los efectos de la contaminación del agua y suelo producto de los residuos de relaves mineros. La actividad económica se basa principalmente en la explotación de los minerales, siendo exclusivos el oro y el uranio. En dichas actividades mineras es imposible la degradación de los desechos provenientes de los relaves, los mismos que contaminan los suelos, aguas superficiales, subterráneas y por ende en los ecosistemas tanto terrestres, como marinos y sus productos a consumir, como los peces y productos agrícolas, en detrimento de la salud de las poblaciones aledañas a las mineras. La presencia de elementos químicos y su alta toxicidad de sus componentes agrava su peligrosidad y su potencial como generador de impactos contaminantes en la salud de las personas y que sufran alteraciones altamente nocivas. Se revisaron 52 artículos arbitrados e indexados de las bases de datos Scopus y Scielo entre los años 2017 al 2020, los efectos de la contaminación del agua y suelo producto de los residuos de relaves mineros. Se concluye que los relaves mineros y el impacto medioambiental ante un proyecto de minería es inevitable, sobretodo en la degradación de los suelos, aguas superficiales, subterráneas y el aire. Esta contaminación provoca la presencia de elementos, minerales y metaloides, que originan perturbaciones en los modos de vida de las poblaciones humanas. Es necesaria la promulgación de las normas que puedan regular e impedir que la contaminación de los relaves siga afectando a la población y al medio ambiente. Finalmente esta revisión ha permitido percibir la necesidad de mayor información que si bien puede existir, existe una urgencia imperiosa del estudio sobre el impacto de contaminación de los relaves mineros sobre la salud humana y ecosistémica.

“…HM concentrations in subsurface soils were also found to be associated with mining activities [14], such as rock blasting, stripping transportation, and solid waste disposal. In a retired uranium mine, the main sources of HM pollution were the mine tailing, electroplating process, and chemical industries [15]. Around a molybdenum mine, barren land was the most polluted [16].…”

Heavy-Metal Pollution Characteristics and Influencing Factors in Agricultural Soils: Evidence from Shuozhou City, Shanxi Province, China

Although soil quality can be highly altered by mining activities, there are few reports on soil pollution in mining cities. We systematically characterized the heavy metals (HMs) pollution, risks, sources, and influencing factors in the surrounding soils of Shuozhou. Specifically, 146 samples were collected, and the potential ecological risk index (RI) and the single-factor index were jointly used to understand the environmental risk of HMs. Meanwhile, correlation analysis was applied to find the influencing factors of HMs. The results of the soil pollution risk assessment in the entire area of Shuozhou were compared with those in the open-pit mine area. (1) The mean concentrations of Cr, As, Cd, Pb, and Hg in our study were found to be higher than the background value. The RI results indicated that most soil samples (82.88%) in Shuozhou had a low potential ecological risk. Compared with the Pingshuo open-pit mine (average RI value: 200.07), the potential ecological RI was lower. (2) The HM correlation indicated that Cr and As were associated with the parent rock, whereas Cd, together with Hg and Pb, were associated with anthropic activities. (3) There was no significant correlation between HM concentrations and farmland slope. Located in the Datong Basin, the terrain of Shuozhou is relatively flat and open and has little impact on the distribution of HMs. (4) Only Hg and Pb have a negative correlation with pH. This suggests that soil with a lower pH value may be beneficial to the accumulation of Hg and Pb in soil. (5) Among the eight industry types examined, the pollution capacity level of the leather, fur, feather, and footwear industries is the strongest, indicating that HMs around LI industry sites represent the maximum level among the eight types.

Cadmium is both extremely toxic and ubiquitous in the natural environment, occurring in most soils, surface waters, and plant tissues. It is readily mobilized by human activities, such as mining [1]. Soils documented in this study featured total concentrations of Cd, Cu, Pb and Zn, exceeding the maximum levels permitted by law [2-3]. Their geogenic heavy metal content reflects geological sources [4]. Unlike organic contaminants, enrichment of heavy metals in soils has attracted a great deal of attention worldwide because they are
