“…It has been observed that to define more accurately the quality of sediments potentially affected by heavy metals and pollutants, a correct option could be an intensive comparison of applied sediment quality guidelines (SQGs) (Burton 2018;Birch 2018;Liu et al 2019;Jones et al 2019). Comparative evaluations of different SQGs for contaminants, in order to obtain an environmental quality and risk assessment of internal waters, has been intensively provided in recent years (Ali et al 2016;Baran et al 2016;Bhateria and Jain 2016;Gopal et al 2017;Strady et al 2017;Xu et al 2017;Shyleshchandran et al 2018;Zhao et al 2018;Aung et al 2019;Kulbat and Sokołowska 2019;Christophoridis et al 2020). It has to be noted that SQGs for the assessment of sediment quality are very different across the different countries.…”

“…They may be transported by channelized flows (such as rivers and streams), or by atmospheric dust and accumulate in natural depressed areas (lakes, seas, and oceans). If it happens, metals may represent a significant part of sediment contaminants and, at some concentrations, they may become toxic to the environment (Farkas et al 2007;Tuikka et al 2011;Shyleshchandran et al 2018;Christophoridis et al 2020).…”

The Pietra del Pertusillo freshwater reservoir is a major artificial lake of environmental, biological, and ecological importance located in the Basilicata region, southern Italy. The reservoir arch-gravity dam was completed in 1963 for producing hydroelectric energy and providing water for human use, and nearby there are potential sources of anthropogenic pollution such as urban and industrial activities. For the first time, the minero-chemistry of the lake and fluvio-lacustrine sediments of the reservoir have been evaluated to assess the environmental quality. Moreover, the composition of fluvial sediments derived from the peri-lacual zone of the reservoir and of local outcropping bedrock were also studied to understand the factors affecting the behavior of elements in the freshwater reservoir, with particular attention paid to heavy metals. In Italy, specific regulatory values concerning the element threshold concentration for lake and river sediments do not exist, and for this reason, soil threshold values are considered the standard for sediments of internal waters. The evaluation of the environmental quality of reservoir sediments has been performed using enrichment factors obtained with respect to the average composition of a reconstructed local upper continental crust. We suggest this method as an innovative standard in similar conditions worldwide. In the studied reservoir sediments, the trace elements that may be of some environmental concern are Cr, Cu, Zn, As, and Pb although, at this stage, the distribution of these elements appears to be mostly driven by geogenic processes. However, within the frame of the assessment and the preservation of the quality of aquatic environments, particular attention has to be paid to As (which shows median value of 10 ppm, reaching a maximum value of 26 ppm in Quaternary sediments), constantly enriched in the lacustrine samples and especially in the fine-grained fraction (median = 8.5 ppm).

“…Temporal and spatial variability of HMs in lakes sediments is usually determined by many overlapping chemical, physical, and biological processes. The pollution is largely variable between lakes as well as within lakes 31 , 32 . The spatial distribution of pollutants is modified by hydrological and hydrodynamic conditions that affect water and sediment transport, as well as the exchange of HMs between water and sediments 33 , 34 .…”

This paper presents the state and spatial distribution of surface sediment contamination of 77 lakes in Poland by Cr, Ni, Cd, Pb, Zn, and Cu. The analyzed lakes were located within a network of nature protection areas in the territory of the European Union (EU). Spatial distribution of the heavy metals (HMs), factors favoring the delivery/accumulation of HMs in surface sediments, and pollution sources were analyzed. The results indicate the contamination of lake sediments by HMs, but the potentially toxic effects of HMs are only found in single lakes. The spatial distribution of Cr indicates predominant impacts of point sources, while for Pb, Ni, and Zn, the impact of non-point sources. The analysis showed the presence of areas with very high values of particular HMs (hot spots) in the western part of Poland, while a group of 5 lakes with very low values of Ni, Pb, and Zn (cold spots) was identified in the central part of Poland. Principal component analysis showed that presence of wetlands is a factor limiting HMs inflow to lakes. Also, lower HMs concentrations were found in lake surface sediments located in catchments with a higher proportion of national parks and nature reserves. Higher HMs concentrations were found in lakes with a high proportion of Special Protection Areas designated under the EU Birds Directive. The positive matrix factorization analysis identified four sources of HMs. High values of HMs concentrations indicate their delivery from industrial, urbanized, and agricultural areas. However, these impacts overlap, which disturbs the characteristic quantitative profiles assigned to these pollution sources.

“…Surface soil samples were collected in Changchun and their concentrations of heavy metal mercury and atmospheric mercury were analyzed. The ecological risks of the heavy metal Hg in the soil were assessed by calculating the geo-accumulation indexes [37][38] and the potential ecological risk indexes [39]. The associated health risks were then assessed by determining the levels of metal exposure through oral ingestion, inhalation, and dermal contact, and then calculating the hazard quotient (HQ), and hazard index (HI).…”

As a typical industrial city in northeastern China, the environmental conditions of the soil in Changchun City face high ecological risks. In the present study, in order to more fully understand the characteristics of the soil mercury content and its related health risks in the main urban areas of Changchun City, the pollution degrees were evaluated using the data of land accumulation indexes (I geo ), potential ecological risk indexes (Er), and health risk assessment methods. The mercury content (TSM) levels in the urban soil, along with the atmospheric mercury content (TGM) levels, were analyzed. The results showed that the mean value of the mercury content in the soil in Changchun City was 0.0569±0.103 mg/kg, and the concentration range was between 0.0052 and 1.3240 mg/kg. It was found that the mercury content levels in nearly 70% of the soil samples exceeded the background value of soil (0.040 mg/kg). In addition, the atmospheric mercury concentration at 0 cm was determined to be directly related to soil mercury content (P = 0.000532). In addition, the atmospheric mercury content of 0 cm was observed to be positively correlated with the distribution of the atmospheric mercury content at 100 cm (P = 0.000524). The mercury content levels in the soil were found to vary from different directions, with the mercury content found to be the highest in the southeastern section of the city. However, there were no significant differences in the mercury content of any direction. The I geo showed that 25.0% of the sample points were polluted. The unsanitary areas were mainly concentrated in the southwestern and southeastern sections of the city. The mercury content levels in the soil of Changchun City ranged from pollution-free to moderate pollution levels overall. The Er indicated that the potential ecological risk level was high in the northwestern and southeastern sections of Changchun City. However, the soil mercury levels in Changchun City presented a low level of ecological risk overall.
