Special Issue Information

Dear Colleagues,

The quality of surface waters indicates the standard of living and the scale of human impact on the environment. Various types of pollutants including heavy metals enter surface waters. Although heavy metals are naturally occurring elements that are found throughout the earth's crust, most environmental pollution and human exposure results from anthropogenic activities associated with the discharge of wastewater from mineral extraction and processing from industrial production and urban operations, and the widespread use of metals and their compounds in a variety of economic activities including, but not limited to, agriculture and automobiles. In addition, it is believed that heavy metals pose a serious threat to the aquatic environment due to their toxicity, non-biodegradability and bioaccumulation capacity and dangerously affect the ecological balance in aquatic ecosystems. Studies on the distribution of heavy metals in the environment, and the toxic effects of pollution are a key focus of ongoing research. Therefore, it is important to control and remove contaminants throughout the process and to properly understand their biogeochemical behavior and biological responses to them. A better understanding of the effects of these pollutants on aquatic ecosystems will provide essential information for environmental risk assessment and identification of anthropogenic impacts thereby contributing to improved knowledge and better management and surveillance of studied rivers and lakes in the future. This Special Issue on metals in the aquatic environment will focus mainly on studies on the occurrence, distribution, migration and transformation of emerging heavy metals and the factors affecting them; occurrence, migration, and transformation of heavy metals in various media (e.g., sediment, water, aquatic organisms); monitoring and analysis of heavy metals in aquatic environments; source identification, temporal and spatial distribution of heavy metals; heavy metal speciation; effects of heavy metals on ecosystems; exposure, bioaccumulation, toxic effect and risk assessment of environmental pollution by heavy metals.

Metals are natural components of the earth’s crust and are essential elements in the metabolism of fauna and flora. However, some metals at high concentrations may pose an ecological risk. Ecological risk analysis is one of the best methods for detecting potential metal pollution problems and its impact on ecosystems. This study analyzed the potential ecological risk and contamination from heavy metals (Cd, Cu, Pb, Ni, Cr, and Zn) in bottom sediments. It analyzed the spatial variability of heavy metal concentrations in the bottom sediments of Lake Bukwałd. The potential ecological risk index (RI) was used to assess the impact of pollutants accumulated in bottom sediments on the environment. In addition to RI, the geochemical index (Igeo) and contamination factor (CF) were also calculated. The pollutant loading index (PLI) was used to compare the average content of metals in the bottom sediments of lakes. The obtained results indicate that agricultural activity determined the quality of the bottom sediments of the reservoir and the spatial content of trace metals in them. Higher concentrations of elements were found in sediments collected from the agricultural catchment, whereas the lowest concentrations were observed near the outflow from the lake. The calculated RI value was 153.3, representing a moderate ecological threat risk. The concentration of cadmium had the greatest influence on the value of the indicator. The analysis of the scale of pollution of bottom sediments using the geochemical index showed that the bottom sediments in terms of the content of most of the trace metals tested are class II. In Cu and Zn, the Igeo index classified these deposits as class 0 and class I. The highest CF values were determined for Cr, Ni, and Pb and classified as significant contamination. The remaining elements were classified as moderately contaminated. The designated PLI was 2.49, suggesting immediate action to reduce pollution and prevent the degradation of the lake. Full article

This study reports the data on the contamination caused by heavy metals in the groundwater of the Campania Plain (CP) in Southern Italy. A total of 1093 groundwater samples were obtained from the following aquifers: coastal plains (GAR, VCP, VES, SAR, and SEL), volcanic districts (PHLE and VES), and carbonate massifs (MAS and LAT). In this study, the investigation depth ranged from 5 m (GAR) to 200 m (PHLE). The sequence of heavy metal content in groundwater samples was B > Fe > Al > Mn > Zn > Ba > Ni > As > Cu > V > Se > Pb > Cd. The heavy metal pollution index (HPI) and heavy metal evaluation (HEI) demonstrated that the study areas in which groundwater samples were sampled are not risk zones. Moreover, health risk assessment shows that hazard index (HI) values for heavy metals were found to be significantly low in groundwater samples. In non-carcinogenic risk evaluation for the adult group, the risk was low, whereas for children and infants, the risk was >1 for arsenic alone. Carcinogenic risk assessment (CR) was found lower for adults, children, and infants. The Jenks optimization method was used to evaluate the distribution of heavy metals in the groundwater of CP, and the principal component analysis technique (PCA) was employed to determine the source of heavy metals, and it was found that mixed sources (natural and anthropogenic) may be responsible for heavy metals presence.
