Summary: The expansion of urban centers, increased use of chemicals in agriculture, and significant growth in industry have resulted in increased amounts of heavy metals being deposited into aquatic ecosystems, directly and indirectly impacting freshwater environments. Studies have shown that these pollutants can cause changes in freshwater fish from molecular to behavioral levels. Despite the diversity of freshwater fish species in the Neotropical region, few studies have been conducted on the influence of metals on native species.

Summary: The study evaluated metal accumulation in the cestodes Proteocephalus macrophallus parasitizing the tucunare, Cichla kelberi, in the Jacare-Guacu River, with lead, cadmium, aluminum, and nickel being well-accumulated elements. The concentration of trace metals in parasites was significantly higher than in the tissues of fish hosts, indicating the cestodes' capacity for metal accumulation. Non-infected fish had higher cadmium and lead concentrations compared to infected fish, and the size of the cestodes' populations influenced metal concentrations in host tissues.

Summary: This study explored the detection of Cd-Pb coaccumulation in rice leaves using hyperspectral imaging. The optimal foliar positions for detecting Cd and Pb contamination were identified, and important wavelengths for detection were also identified. The results showed that diagnostic accuracies varied based on the different foliar positions.

Summary: The study found high levels of heavy metals and microplastic particles in oysters from the Paranagu?a Estuarine System. While microplastics were present in oysters from all sampled locations, there was no demonstrated direct relationship between microplastics and heavy metals, indicating that microplastic particles may not be the main route for heavy metal contamination of oysters in the system.

Summary: The consumption of contaminated finfish from the polluted river of Turag-Tongi-Balu, Kamarpara site, Dhaka poses significant health hazards to humans, with the concentrations of Cd, Mn, Pb, and Se exceeding the Food Safety Guideline value in most fish species. The high Mn concentrations in certain fish species elevate the non-carcinogenic risk, and there are statistically significant differences in heavy metal concentrations among fish species. The regular dietary consumption of fish from this polluted ecosystem poses a significant health risk and is indicated as cancer, emphasizing the importance of monitoring heavy metal contamination and minimizing the risk to human health.

Summary: Zinc is an abundant heavy metal in the Earth's crust and is essential for the growth of living beings. It can be both beneficial and toxic. While it can be obtained from vegetables, beef, and dairy products, excessive intake of zinc supplements can lead to toxicity. In the environment, excessive levels of zinc can affect soil and water microbial diversity and the bioavailability of other metals. Certain bacteria have been identified as promising agents for zinc bioremediation.

Summary: The toxic discharge of heavy metals into the water affects both the aquatic ecosystem and the human population interacting with it. It is important to conduct studies to determine the level of heavy metal pollution in order to better control and manage the pollution of aquatic ecosystems. This study assessed heavy metal contamination in fish and its associated health risk to the population around the Tarukri Drain, Punjab, Pakistan. The results showed that heavy metal contaminations in both fish species were within the permissible limits recommended by the World Health Organization (WHO).

Summary: This paragraph illustrates the basic requirements of the European Union regarding appropriate water quality for fish habitat and the parameters, analysis methods, and frequencies to be controlled. Through a case study in the Podhale region of southern Poland, the impact of geothermal water discharge on river water quality and the quality of salmonid fish life was evaluated, leading to the development of a Fish Water Pollution Index.

Summary: Insects are a novel feed protein source that can contribute to producing enough food for the growing global population. The high-quality protein, minerals, and bioactive compounds found in insects make them suitable for livestock feed. However, it is crucial to ensure the safety of insects before using them as feeder insects.

Summary: The increasing global demand for electric and electronic equipment has led to an increase in heavy metal pollution, affecting fish in African waters. Tuna species from African waters, such as Thunnus alalunga, have higher concentrations of heavy metals, especially Hg, compared to those caught in other areas. The study highlights the need to address research priorities to improve the social and environmental sustainability of EEE metal manufacture in Africa.
