“…Chromium extraction from the mines has been excessively increased due to its increasing use in various industries [2]. Kazakhstan, South Africa, China, and India are the world-leading Cr using countries [2,6,7]. Leather tanning, metallurgy, electroplating, alloying, ceramic glazes, wood preservation, water corrosion inhibition, refractory bricks, pressure-treated lumber, textile dyes, and mordant, pigments and paints production, and paper and pulp production industries contribute to the hyperaccumulation of Cr in the environment.…”

Chromium (Cr) is one of the top seven toxic heavy metals, being ranked 21st among the abundantly found metals in the earth’s crust. A huge amount of Cr releases from various industries and Cr mines, which is accumulating in the agricultural land, is significantly reducing the crop development, growth, and yield. Chromium mediates phytotoxicity either by direct interaction with different plant parts and metabolic pathways or it generates internal stress by inducing the accumulation of reactive oxygen species (ROS). Thus, the role of Cr-induced ROS in the phytotoxicity is very important. In the current study, we reviewed the most recent publications regarding Cr-induced ROS, Cr-induced alteration in the enzymatic antioxidant system, Cr-induced lipid peroxidation and cell membrane damage, Cr-induced DNA damage and genotoxicity, Cr-induced ultrastructural changes in cell and subcellular level, and Cr-induced alterations in photosynthesis and photosynthetic apparatus. Taken together, we conclude that Cr-induced ROS and the suppression of the enzymatic antioxidant system actually mediate Cr-induced cytotoxic, genotoxic, ultrastructural, and photosynthetic changes in plants.

“…With the profound change of land use, the ecological environment will be seriously damaged, and the risk grade will sharply rise when a resource-based city is in the recession period. Therefore, the resource-based cities have become a hot issue for the research of restoration ecology [21][22]. Many experts called for a mechanism by which environmental monitoring, risk assessments and policy decision making should be developed [11].…”

A healthy ecosystem provides various ecological services for human beings and it is the foundation for the sustainable development of human society. However, human activities and natural disasters inevitably interfere with the evolution of an ecosystem at different scales [1-2]. Ecological risk refers to the possibility that the ecosystem structure and function will be degenerated under external pressure [3]. Ecological risk assessment (ERA) is an effective method for quantifying

There is no doubt that mine tailings and waste are an environmental problem and can be a risk to human health and other organisms. Although many studies about acid rock drainage have been performed, the dispersal of trace elements and their impact on the environment (groundwater, soils and agricultural use) and the long-term (i.e., decades to centuries) behaviour of mine tailings on silicate parent rock is still a matter of debate. Our main scope was, therefore, to develop an approach that enables a relatively fast and reliable prediction of the leaching of potentially toxic elements and, thus, to determine the reactivity of former mining sites. To do so, we traced back the leaching behaviour of metals such as copper (Cu), chromium (Cr), cadmium (Cd) and lead (Pb) in soils formed on tailings from small mines over a relatively long time period. Using a chronosequence approach based on historical records of mining activities and C-14 dating, element leaching could be traced over a time period of approximately 1000 years for the historic mining sites at Mont Chemin (Switzerland). The weathering index B, that expresses chemical leaching of base cations and weathering of silicate minerals, and trace element ratios to immobile compounds (such as hafnium (Hf)) indicated that element leaching, and thus reactivity of the material, was very intense during the first 200 years after abandonment of the site. Between approximately 200-400 years, the rate of elemental change in the soils was strongly reduced tending (moderate reactivity) to very small values, and consequently low reactivity, for exposure ages of > 400 years. Thus, the chronosequence approach enabled to determine the reactivity of the sites. Soil organic carbon and oxyhydroxides were not effective enough to completely retain trace metals. Many former small mining sites exist in the Swiss Alps. Using a database that contains information about the period of activity, date of abandonment, elements used and geology, we extrapolated our findings to sites in Switzerland with moderately comparable conditions to Mont Chemin. This relatively simple empirical approach enabled a spatialisation and rough estimation of the sites regarding their reactivity. A large number of small mining sites in Switzerland were characterised as still highly reactive and only a few were considered to be weakly reactive. With the help of the chronosequence approach and extrapolation of the small former mining sites, a relatively fast overview of the reactivity of sites could be achieved. This approach, however, cannot substitute for a detailed risk analysis of such sites.
