“…When these heavy metal(loid)s in the acid mine drainage are discharged into the surface water, they can be transported for a distance of a few kilometers by the hydrodynamic forces [11]. In addition, fine-grained mine tailings can be carried away by strong winds and contaminate the surroundings [12]. Heavy metal(loid) pollution near mines has been reported extensively [3,11,13].…”

During mining, some of the essential metal(loid)s for plants or humans are discharged into the environment with non-essential metal(loid)s. Thus, comprehensive investigations of their distribution and the health risk of consuming food crops near mines are significant. A total of 26 soils and 25 food crops (soybean grains and wheat grains) were sampled to investigate arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), mercury (Hg), lead (Pb), zinc (Zn), selenium (Se), molybdenum (Mo), and manganese (Mn) in soils and crops in a typical non-ferrous metal mine area in Northeast China. The distribution patterns of soil heavy metal(loid)s and principal component analysis (PCA) results indicated that Cd, Cu, Zn, Mo, and Mn in soils were significantly affected by mining activities and were mainly or partly derived from the mines. Moreover, these soil heavy metal(loid)s (except Se) in the Tongshan copper mine area were attenuated with distance in the downstream direction. The BCF (bioconcentration factor) values of non-essential elements (Se, Hg, Cr, As, Cd, Pb) were relatively lower and positively related to soil nutrients. On the contrary, higher BCF values of essential elements (Cu, Zn, and Mo) and a weak relationship between the BCF of essential elements and soil nutrients were found. The mean Igeo values of soil heavy metal(loid)s indicated that As and Cu were at an unpolluted-to-moderately-polluted level (Igeo > 1), while other heavy metal(loid)s all presented an unpolluted level (Igeo < 1). Nevertheless, some soil samples were obviously polluted (Igeo > 1), such as KQ, D1, D3, D5, D6, and T1. The HQ (hazard quotient) and HI (hazard index) values of As and Mn both exceeded 1, indicating the higher potential health risks of consuming soybean grains and wheat grains for all people groups.

“…This makes 3DBC attractive for projected simulations of NPS, as 3DBC performs in a dimensionally independent manner and can specifically reflect climate change signals. For example, the mobility of heavy metals is closely related to both temperature and precipitation (Liu et al 2020 ; Punia 2021 ); thus, 3DBC may allow the response of this process to climate change to be modeled. Moreover, 3DBC is likely to function for latitude/elevation-based freeze-thaw processes in watersheds in which freezing influenced by temperature and precipitation changes alter the water conductivity and erosion resistance of the soil (Ouyang et al 2018 ).…”

Understanding dynamic future changes in precipitation can provide prior information for nonpoint source pollution simulations under global warming. However, the evolution of the dependence structure and the unevenness characteristics of precipitation are rarely considered. This study applied a two-stage bias correction to daily precipitation and max/min temperature data in the Daqing River Basin (DQRB) with the HadGEM3-RA climate model. Validated from 1981 to 2015, future scenarios under two emission paths covering 2031–2065 and 2066–2100 were projected to assess variations in both the amount and unevenness of precipitation. The results suggested that, overall, the two-stage bias correction could reproduce the marginal distributions of variables and the evolution process of the dependence structure. In the future, the amount of precipitation in the plains is expected to increase more than that in the mountains, while precipitation unevenness, as measured by relative entropy, shows a slight increase in the mountains and a decrease in the plains, with enhanced seasonality. Conditioned on rising temperatures, high-/low-intensity precipitation tends to intensify/weaken precipitation unevenness. Additionally, the potential application of the bias correction method used herein and the possible impacts of uneven precipitation on nonpoint source pollution are given for further analyses. This study can provide useful information for future nonpoint source pollution simulations in the DQRB.

“…Mining industry is still a global source of air, water and soil pollution since it typically generates important amounts of waste (i.e., tailing impoundments, dumps and hard rock deposits), without an apparent control of spillage (Zhao et al 2020;Myagkaya et al 2021). Mining waste usually contains significant amounts of metal sulfide (MS) grains, which are present as free and/or occluded minerals in bulk, whence they are easily dispersed by eolic and/or pluvial processes highlighting environmental and health risks due to release of potentially toxic elements (i.e., As, Pb, Cr, Co, Ni, Zn, Cu, Hg) (Punia 2021;Myagkaya et al 2021). Among the main MS causing these problems are pyrite (FeS2), pirrothite (Fe1-xS), sphalerite (ZnS), galena (PbS), chalcopyrite (CuFeS2), and arsenopyrite (FeAsS) (Scoble et al 2003;Lottermoser 2010).…”

The present study combines surface analyses of pristine and leached low Fe-bearing and Pb-bearing sphalerite (PbS-ZnS) samples including XPS, GDOES, Raman spectroscopy, SEM and AFM, along with chemical evolution of leachates after 24 h of contact with 0.1 M NaOH, 0.1 M NaNO3, 0.1 M H2SO4 or 0.1 M HClO4 solution. A comprehensive electrochemical analysis using Cyclic voltammetry, Chronopotentiometry, Chronoamperometry, Linear sweep voltammetry and Tafel plots of PbS-ZnS and marmatite-like sphalerite (FeZnS) are conducted to compare its oxidation activities. Mineral characterizations reveal sluggish weathering linked to inhomogeneous and minor secondary polysulfides (Sn2−) surface compounds distribution, thus defining bare modifications of surface-activity relationships. The occurrence of secondary Zn-bearing compounds was not identified on altered samples, which suggests that this heavy metal diffuses into the bulk-solution. Electrochemical assessments confirm sluggish sphalerite oxidation mainly composed by two subsequent stages, where the highest mineral activity was obtained in NaOH conditions. It was found that the sphalerite oxidation is more active in the presence of Pb, while the activity of sphalerite gradually decreases when it is a mineral rich in Fe probably associated with progressive accumulation of Sn2−/S0 compounds. We suggest general oxidation mechanisms for sphalerite, and their environmental implications are discussed.
