Summary: To assess metal pollution in the Wujiang River, concentrations of eight metals were examined in the water, sediments, and two fish species. The results showed that metal concentrations were generally below the water quality standards. The sediments in the lower reaches had higher bioavailability and mobility of certain metals, indicating increased risk of secondary release. Although metal concentrations in fish varied, the overall health risk from consuming fish was low for the general public due to prohibited commercial fishing.

Summary: This study measured the concentrations of Cd, Ni, and Pb in the liver and muscle tissues of two fish species, Barbus grypus and Tenualosa ilisha, collected from the Karoon River in Iran. The potential human health risks associated with these heavy metals were evaluated using EDI, THQ, HI, and TR. The results emphasize the importance of habitat and feeding habits in the uptake of HMs by these fish species. The study found that the EDI for all HMs exceeded the RfDo provided by the USEPA, indicating potential safety concerns for human consumption. The THQ values were within the permissible limit, while HI values indicated non-carcinogenic risks for consumers. The TR values for Pb were within an acceptable range for both species.

Summary: Tetrabromobisphenol A bis (allyl ether) (TBBPA-BAE) is a widely used brominated flame retardant with neurotoxic and endocrine disruption effects on aquatic organisms. This study investigated the bioconcentration, elimination kinetics, and biotransformation of TBBPA-BAE in common carp. The results showed rapid accumulation of TBBPA-BAE in the fish, with the highest concentrations found in the liver and the longest residence time in the kidney. Biotransformation of TBBPA-BAE was observed, with 14 different metabolites identified in the liver. These findings highlight the importance of considering the biotransformation products of TBBPA-BAE in risk assessment.

Summary: This study investigated the combined effects of copper and polyvinyl chloride (PVC) microparticles on metal accumulation, histopathological biomarkers, and targeted transcriptomics in Cyprinus carpio liver. The presence of PVC microparticles in water facilitated hepatic copper accumulation. All treatments induced significant hepatic stress and inflammation, but transcriptional responses related to detoxification pathways and apoptotic mechanisms were mixed and often down-regulated in fish exposed to copper and/or PVC microparticles. Exposure to copper and/or PVC microparticles resulted in hyperemia, leukocyte infiltration, and an increase in melanomacrophage centers number and area. Generally, the severity of the lesions followed the order: PVC microparticles < copper < copper+ PVC microparticles. In conclusion, PVC microparticles act as a copper vector, facilitating copper accumulation in the fish liver and increasing tissue damage.

Summary: Green evolutionary products, such as biologically synthesized silver nanoparticles (AgNPs), can be hazardous to aquatic organisms. This study synthesized biogenic AgNPs using ionic silver and onion peel extract and characterized their properties. The toxicity of these AgNPs was evaluated on common carp fish, showing significant hematological alterations, oxidative stress, and histological damage in vital organs. Furthermore, the fish treated with these AgNPs exhibited downregulation of oxidative stress genes. This study provides evidence of the influence of biogenic synthesized AgNPs on aquatic life through induction of oxidative stress.

Summary: Several international organisations have recommended the use of bioindicators to improve the evaluation of ecological risk in marine ecosystems. In this study, wild mussels were collected from thirty sampling points along the Asturias coastline and analyzed to identify the relationship between metal concentrations in mussel tissues and the geological and environmental conditions of the coastal area. The study revealed concentration trends for different metals and correlations between them. The mussels also showed natural defense against certain metals. Cluster analysis of the samples grouped them based on the sources of the metal concentrations. Both anthropic and natural sources have led to an increase in metal loads in mussels, sometimes exceeding international environmental criteria.

Summary: Petrochemical plants are the main sources of rare earth elements (REEs) in the Musa estuary, and the accumulated REEs in sedimentary beds can be released into the water column under different redox conditions. A study using a biogeochemical microcosm system found that the release of REEs in an estuarine sediment sample was influenced by the redox potential (Eh). The average mobilization rate of REEs was 31.03% under reducing Eh. Cluster analysis and principal component analysis showed that Eh indirectly affected the solubility and release of REEs through the linked changes of dissolved organic carbon (DOC) and chemistry of Fe-Mn. Enrichment factors (EFs) revealed that the Musa estuary is threatened by Ce, Dy, La, Nd, Pr, and Sm. Serious consideration should be given to the high potential mobility of REEs due to their ecotoxicological effects causing environmental risk and health issues.

Summary: Due to the use of fossil energy resources, power generation has become the primary cause of pollution and greenhouse gas emissions. In order to address this issue, seven scenarios for decreasing greenhouse gas emissions in the power industry were defined and evaluated in terms of technical, economic, and environmental factors. The results showed that developing renewable power plants alone is not the most suitable option for reducing emissions. Instead, improving efficiency in thermal power plants, such as through the development of combined cycle power plants and repowering steam power plants, is a more feasible solution. By adopting a combined scenario that includes reducing the share of thermal power plants and increasing the share of renewable power plants, significant reductions in pollution and greenhouse gas emissions can be achieved.

Summary: This study investigates the effects of internalizing environmental costs on technical, environmental, and economic aspects of electricity production. Historical data and benefit transfer economic method were used to calculate the environmental costs associated with different methods of electricity generation per kilowatt-hour. MATLAB software was utilized to internalize these costs into private electricity generation costs. The results show that thermal power plants have environmental costs ranging from 0.052 to 0.135 C$/kwh. Internalizing these costs can lead to an increase in the share of clean and renewable technologies and a decrease in fossil energy plants. From 2017 to 2050, fossil fuel consumption is expected to decline by about 124 billion m(3) of natural gas equivalent, with a reduction in pollutant and GHGs emission. The overall cost of producing electricity will also decrease significantly. However, limitations on other sources of electricity production and existing policies contribute to the dominance of thermal power plants.
