Summary: The overall heavy metal contamination status of surface water bodies in Greece generally meets environmental quality standards, but sediment heavy metal concentrations often exceed guidelines. A few rivers and lakes are moderately to highly contaminated by heavy metals.

Summary: This study examines the contamination, accumulation, and ecological risk of five trace metals in sediments of an urbanized beach in Morocco. The results show that, overall, the sediments were within the acceptable limits, indicating low contamination and low ecological risk. However, there was an increase in Cd levels in 2019 due to anthropogenic activities, leading to moderate pollution and moderate ecological risk. It is recommended to reduce avoidable human activities to mitigate metal pollution in the study area.

Summary: This study investigated the interactions between organic matters in sediments and trace metals in river estuary, revealing that both protein-like molecules and marine humic acids can react with Cu2+ and Cd2+. Protein-like molecules were more sensitive and Cu2+ had stronger binding ability compared to marine humic acids. Cd2+ showed higher environmental risks due to its higher migration and transformation. Thermodynamic results indicated that the reaction between WEOM and trace metals was spontaneous, exothermic, and favored at low temperatures.

Summary: Trace metals in sediments from the Chester River were investigated to understand their distributions and potential sources. The concentrations of lead, arsenic, nickel, chromium, and copper exceeded sediment toxicity guidelines in a significant proportion of samples. Enrichment factors for cadmium, silver, lead, arsenic, and zinc were elevated above natural background levels. Nickel, copper, zinc, and cadmium showed significant differences in enrichment factors between different segments of the river. Cadmium and arsenic enrichments were most likely from the application of fertilizers in the watershed, while active marinas were identified as important sources of metal enrichment, especially for copper.

Summary: Pollution risk assessment of heavy metals in sediment samples from the Gulf of Edremit in western Turkey was conducted using various pollution assessment indices. The results showed low contamination levels in the surveyed area, except for moderate contamination of arsenic. Ecological risk assessment indicated frequent adverse biological effects of arsenic, chromium, and nickel on aquatic organisms.

Summary: The study found that trace elements in surface sediments of the Hooghly estuary were contaminated by anthropic sources, especially As, Cd, and Ni, reaching the worst levels post-monsoon. Sediments showed varying degrees of pollution during monsoon seasons and at different locations, with an overall severe ecological risk present.

Summary: This study investigated the impact of the monsoon season on heavy metal loads in the sediments of the Hooghly River in India from 2014 to 2017, a previously unexplored time frame. The results revealed significant correlations between certain metals, suggesting contributions from industrial activity. The monsoon season was found to significantly increase the transport of metals, mainly due to weathering of continental detritus. The levels of certain metals, especially nickel, posed a significant threat to the aquatic ecosystem.

Summary: The study combined biotic indices, geo-accumulation index, and a multivariate approach to assess anthropogenic influence on the benthic community in the Swarnamukhi river estuary. The results showed extreme disturbance and bad ecological status at the BC station, with metal contamination of Cd in the sediment. The study demonstrated the effectiveness of the combined approach for ecological assessment of coastal ecosystems.

Summary: The purpose of this study was to investigate the mobility, spatial distribution, possible sources, and potential ecological risks associated with trace metals Cu, Mn, and Ni in sediments around industrial and artisanal gold mines in northern Cote d'Ivoire. The results indicated that the concentrations of Cu, Ni, and Mn did not vary across different sampling stations. The possible pollution sources were identified as both anthropogenic and natural inputs. The extraction procedure showed low mobility of these trace metals. The risk assessment indicated low-to-medium risk for organisms.

Summary: Plastic waste is a serious environmental problem and can release contaminants into the environment. This study evaluated the release of metals from plastics under different soil solution types, artificial root exudates, and distilled water. The results showed that metal release was most efficient in soil solutions, followed by root exudates and least efficient in distilled water. Different types of plastics differed in their metal release concentrations, with LDPE releasing the highest concentrations of Cu and Na, PP releasing the most Fe, and PET releasing the most Cr. The release of metals from plastics was also influenced by pH, dissolved organic carbon concentrations, and electrical conductivity of the solutions. Plastic extracts were found to have negative effects on germination and growth in Lepidium sativum.

Summary: This article focuses on the content of heavy metals in the bottom sediments of the estuary of the Pechora River. The study found that the concentrations of heavy metals in the sediments are low, indicating a low level of environmental risk.

Summary: The study found that the average concentrations of six heavy metals in the sediment of the lower Meghna River estuary were ranked in descending order of iron (Fe), zinc (Zn), lead (Pb), chromium (Cr), copper (Cu), and cadmium (Cd). The geo-accumulation, contamination, and pollution load indexes indicated that the estuary was not contaminated by Fe, Zn, Pb, Cr, and Cu. There was a significant correlation between sediment grain size and the association of iron (Fe) and lead (Pb), but no significant correlation was found between other metals and grain size.

Summary: A variety of pollution indices were used to assess the contamination of different metal elements in the Boka Kotorska Bay, with Cd and Hg identified as the highest risks and Tivat bay as the most polluted area. The study also found a decreasing trend of Hg over time and highlighted the major concern of Cd in the Bay environment.

Summary: Laguna de Bay in the Philippines, the third largest lake in Southeast Asia, is a significant source of freshwater fish. However, unregulated discharge of industrial, domestic, and agricultural wastewaters has led to heavy metal contamination in the lake, which affects the toxicity of the popular Asiatic clam. The study found that the western part of the lake had higher concentrations of certain heavy metals in the sediment compared to the eastern part, and there were correlations between the sediment and the Asiatic clam.

Summary: The study found that arsenic and mercury concentrations in rice grains grown in wetlands in central-southern Cote d'Ivoire exceeded permissible limits, while cadmium concentrations were below the limit. Rice consumption poses potential health risks of arsenic exposure for adults and children in the area.

Summary: This study assessed the concentrations, fluxes, and potential health risks of trace metals in the waters at the mouth of three transboundary rivers in West Africa. The results showed that the metals mainly came from anthropogenic sources and although the concentrations were lower than international guidelines, there was still a significant risk of community exposure to harmful effects.
