Summary: This study aimed to establish bioaccumulation background data in the spotted ratfish Hydrolagus colliei by measuring the distribution of As, Cd, Cu, Pb, and Zn in the muscle and liver. The liver showed higher bioaccumulation than the muscle in all the studied elements, and the sex did not influence the bioaccumulation. The concentrations of As in the muscle did not exceed the maximum permissible limits, while Cd and Pb concentrations exceeded certain regulations.

Summary: This study used a systematic literature review to identify sources of potentially toxic elements (PTEs) in the aquatic environment. The analysis revealed both natural and anthropogenic sources, such as mining, agriculture, industries, and domestic effluents. The study also highlighted specific locations where environmental remediation studies should be conducted to prevent and address PTE pollution.

Summary: A warning microanalyzer using Carbon Dots as selective optical reagents for the rapid monitoring of different heavy metals in water is presented. The system combines microfluidics with selective fluorescence quenching by heavy metal ions, providing sensitivity, automation, and reproducibility. It can also be used as a toxicity control system by selectively measuring heavy metal ions.

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: The present study investigated the levels of Fe, Pb, Cu, and Zn in algae samples collected from three different locations in Algeria. The results showed high concentrations of heavy metals in all four species, with Pb, Fe, and Cu levels surpassing the recommended standard. Zn levels were below the standard. Principal component analysis confirmed that the heavy metal pollution in these waters originated from anthropogenic activities.

Summary: Fish are a significant source of protein and nutrients, but they may also contain harmful substances like heavy metals. This study aimed to evaluate the concentrations of heavy metals in different muscles of two commercial fish species from the southern coast of the Caspian Sea. The results showed that concentrations of mercury, lead, and cadmium exceeded EU regulations for fish, indicating heavy metal pollution in the sampled region. Continued monitoring and evaluation of pollution levels in the Caspian Sea will be necessary.

Summary: Trace metals play a crucial role in regulating primary productivity and phytoplankton community composition in natural waters. Voltammetric methods, such as ASV and CLE-AdCSV, have been widely adopted for metal speciation analysis in various aquatic systems, with a focus on discriminating labile/inert fractions, redox species, and covalently bound species.

Summary: Pollution poses a major threat to marine life, and trace elements are highly toxic pollutants in this environment. Zinc, an essential trace element for biota, becomes toxic at high concentrations. Sea turtles, with their longevity and widespread distribution, are good bioindicators for trace element pollution, accumulating these elements in their tissues over the years. This study compared the bioaccumulation of zinc in the liver, kidney, and muscles of 35 green sea turtles from Brazil, Hawaii, the USA (Texas), Japan, and Australia. The results showed that zinc was present in all specimens, with the highest concentrations in the liver and kidneys. The findings of equal zinc values in the liver suggest a pantropical distribution pattern for this metal, possibly due to its essential nature and bioavailability in marine environments. This study highlights the importance of understanding the distribution patterns of trace elements in marine biota for conservation purposes and suggests that green turtles can serve as useful sentinel species.

Summary: The study analyzed potential harmful trace elements in sediment cores from Lake Marbore, reconstructing the fluxes of trace metal pollutants over the last 3000 years in the Central Pyrenees. The research revealed a strong mining-related pollution legacy in alpine lakes and watersheds, emphasizing the need for consideration in management plans for mountain ecosystems.

Summary: Penguin guano is a suitable bioindicator of environmental contaminants in the Antarctic environment. This study determined the release rate of trace metals from penguin guano to seawater and estimated the annual release of soluble metals by Gentoo penguins. The results show that a significant amount of trace metals are released within the first two hours, and the estimated yearly release of metals by the Gentoo penguin population is substantial.

Summary: The addition of Large Wood Debris (LWD) in natural flood management schemes led to increased macroinvertebrate abundance and taxa richness in the intervention zone, with no change in water quality parameters. The presence of LWD caused a clear separation in invertebrate communities and led to the establishment of taxa that were otherwise absent. Additionally, LWD altered sediment distribution in the stream, improving biological complexity and niche availability in the in-channel zone.

Summary: Woody plant material has the potential to produce biofuels and other bio-based products with favorable CO(2) emissions. Recent research demonstrated the use of flexible moldable wood to generate novel structural materials. The Apple rubbery wood (ARW) disease causes increased flexibility in woody stems due to a viral infection. The symptoms of ARWV infections arise from reduced lignification in the secondary cell wall of xylem fibers, resulting in increased wood digestibility. The downregulation of PAL, the enzyme involved in lignin biosynthesis, and the accumulation of PAL-derived vasiRNAs contribute to the altered lignin in the infected wood.

Summary: The combined effects of increased water temperature and microcystin concentrations as co-stressors on survival and ecological processes in freshwater species are unclear. We tested the individual and combined effects of three water temperatures and a range of microcystin and crude extract concentrations on survival, growth inhibition, grazing and predation rates in three freshwater species. Our findings highlight the importance of complex ecological mechanisms by which warming can exacerbate toxic effects of cyanobacterial bloom extracts on survival and functions among species in eutrophic freshwaters.
