“…Invasive plants that perform a similar function can increase the bioavailability of soil microelements [ 62 ]. Additionally, microelements contained in plant tissues can be released into the environment by degradation of litter, other organic matter, and diagenesis [ 62 , 63 ]. During the decomposition of invasive plant litter, an increase in soil pH might indirectly result in the mobilization of microelements in the soil.…”

Predicting the direction and magnitude of change in soil dynamics caused by invasive plant species has proven to be difficult because these changes are often reported to be species- and habitat-specific. This study was conducted to determine changes in three soil properties, eight soil ions, and seven soil microelements under established stands of four invasive plants, Prosopis juliflora, Ipomoea carnea, Leucaena leucocephala, and Opuntia ficus-indica. Soil properties, ions, and microelements were measured in sites invaded by these four species in southwest Saudi Arabia, and these values were compared to the results for the same 18 parameters from adjacent sites with native vegetation. Because this study was conducted in an arid ecosystem, we predict that these four invasive plants will significantly alter the soil properties, ions, and microelements in the areas they invaded. While the soils of sites with the four invasive plant species generally had higher values for soil properties and ions compared to sites with native vegetation, in most instances these differences were not statistically significant. However, the soils within sites invaded by I. carnea, L. leucocephala, and P. juliflora had statistically significant differences for some soil parameters. For sites invaded by O. puntia ficus-indica, no soil properties, ions, or microelements were significantly different compared to adjacent sites with native vegetation. Sites invaded by the four plant species generally exhibited differences in the 11 soil properties, but in no instance were these differences statistically significant. All three soil properties and one soil ion (Ca) were significantly different across the four stands of native vegetation. For the seven soil microelements, significantly different values were detected for Co and Ni, but only among stands of the four invasive plant species. These results indicate that the four invasive plant species altered soil properties, ions, and microelements, but for most of the parameters we assessed, not significantly. Our results do not support our initial prediction, but are in general agreement with previous published findings, which indicate that the effects of invasive plants on soil dynamics vary idiosyncratically among invasive species and among invaded habitats.

“…It was observed that the arsenic in collected samples represent a potential risk for human health through ingestion. Ermakov et al (2015) evaluated the impact of natural and anthropogenic factors on migrations of heavy metals in the downstream and flood plain soils of the mining and industrial areas of the Misursk Mining Combine and its Arkhon-Khosta Tailings, which increase Pb, Cd, Cu, and Zn content to background values. A catastrophic mud flow of 2002 and the later construction of a gas pipeline and a dam for hydroelectric power station changed the landscapes and biota.…”

“…Mining-related pollution affects not only the immediate vicinity of mines but also the hydrosystem further downstream [25]. The migration and diffusion of heavy metals in water systems and how they impact on water quality in surroundings or downstream water bodies still remain a challenge [26,27,28].…”

“…In order to evaluate environmental risks of heavy metals and arsenic caused by mining activities, the effects and relations with respect to the natural environment, artificial pollution due to mine waste residue, and emissions as a result of human activities should be estimated. Another challenging task for water management is to identify the main anthropogenic pollution sources and to assess their downstream environmental impacts [28,29]. Geographic information systems (GIS) are widely employed in the environmental studies to approximate the regional causes of water pollution [30,31,32,33] and land use/land cover effects on water quality [34,35,36].…”

Aquatic ecosystems continuously receive potentially hazardous heavy metals from natural and anthropogenic sources. Focusing on the origin of heavy metals, this study aims to estimate the load contribution of tributaries from individual watershed and human drainage and to dissect the source of heavy metals, as commonly required for environmental impact assessment. Using integrated water dynamics, Geographic Information System (GIS), and chemical analysis, we identified and evaluated the heavy metal sources of the Kosaka river system in Hokuroku basin, which is a historically mined area in Northeast Japan, both in the high-water and low-water seasons. The migration and diffusion behaviors of heavy metals along with hydro-transport were analyzed, and the effects of mining activities on regional water quality both in the high-water and low-water seasons were clarified. The results indicate that Zn pollution was obvious in the Kosaka River network, especially in the downstream area. The spatial heterogeneity of heavy metal outflows from tributary watersheds was obvious, and the variations had strong correlations with mine site locations. The heavy metal flows in the mainstream increased sharply in the vicinity downstream of the Kosaka refinery drainage outlets. Compared to the low-water season, the influences of human drainage were slighter in high-water season, with lower contribution rates due to the dilution effect of the greater water discharge. Downscale sampling is effective to identify pollutant sources in regional basins.
