Summary: This study investigates the distribution of mercury in the atmosphere, soil, water, and sediment around Mambulao Bay in the Philippines. The results show that the atmospheric mercury concentration on the east shore side is significantly higher than on the west shore side, and rivers are the main sources of mercury in the bay. The mercury released by artisanal and small-scale gold mining activities can affect the bay's ecosystem.

Summary: Phosphorus is essential for all living organisms, but it can also contribute to eutrophication of aquatic ecosystems. Kettle holes, located in intensively used agricultural areas, pose a risk of nutrient transfer to larger water bodies. This study investigated the composition of phosphorus in arable soils and kettle hole sediments, revealing a dominance of stable forms of organic phosphorus. The results also showed a higher proportion of complex organic phosphorus in kettle hole sediments, suggesting their potential for conserving phosphorus and reducing its transfer to vulnerable aquatic ecosystems.

Summary: This study conducted a comprehensive investigation on the level of total Hg (THg) in different environmental media in Itacaiunas River Watershed (IRW), Brazil, aiming to understand the source and distribution of Hg and its potential risks to ecological and human health. The results showed that most of the soils and sediments had higher Hg content compared to the average values, but only a few samples exceeded the legal limits. The water samples were not significantly contaminated by Hg. The distribution of Hg in soils and sediments was closely related to geological factors, indicating limited anthropogenic influence. The main factor controlling the distribution of Hg was organic matter. The ecological and health risk assessments revealed low pollution and non-carcinogenic health risks. This study provides important information for Hg risk assessment and future research in the Amazonia region.

Summary: This study quantified the concentrations of total mercury (Hgtot) and methylmercury (MeHg) in sediment and mussels in the east basin of the Orbetello lagoon. The results showed that Hgtot concentrations in sediments exceeded the environmental quality standard, while the Hgtot concentration in mussels did not exceed the limit values of the European food legislation. The findings suggest that these compounds can accumulate in the upper levels of the trophic chain in the lagoon, posing a risk to human health.

Summary: The study investigated the long-term vertical and horizontal mobility of mercury in soils of an historically contaminated agricultural area in Italy. The research found variations in mercury concentrations with depth and spatially within the same field, influenced by factors such as mercury loading, soil properties, and the presence of different plant species. Additionally, a greenhouse experiment demonstrated that certain plant species can affect the mobility and potential bioavailability of mercury in soils.

Summary: The research on the former mercury ore deposit of Mernik in Eastern Slovakia found that regardless of the type of extraction, the soluble ratios of metals in mine soils increased in the order of Hg <= CrCH3COOH approximate to EDTA >> H2O. The ability of the common nettle to accumulate trace metals in roots and aerial parts mirrored the results of extraction tests.

Summary: This study analyzed heavy metal contamination and Hg-resistant bacteria in soil and sediment samples from the Ulindi River in the Democratic Republic of the Congo. The concentrations of most metals were low, except for As and Cr in soil samples. The densities of heterotrophic bacteria populations ranged from 2.88 to 33.36 CFU 10(6) g(-1) in soil samples. Molecular analysis confirmed the presence of Hg-resistant bacterial strains, which will be further evaluated for their potential in bioremediation of Hg-contaminated soil/sediments.

Summary: The Yellow River, a high-sediment river, releases significant amounts of mercury and methylmercury into the Bohai Sea. Sediment regulation can increase mercury flux to the ocean, while water diversion has a minimal impact on mercury flux. This study highlights the importance of understanding mercury transport and its impacts on coastal ecosystems.

Summary: Human activities have caused serious soil mercury pollution in industrial areas worldwide. Mercury contamination in soil was found to be significantly elevated in areas of mercury mining, gold mining, and zinc smelting, with atmospheric deposition speculated as the main pathway for soil mercury contamination. Speciation and concentration of mercury in emission gas are crucial factors for mercury pollution in surrounding soils.

Summary: The study found that marine sediments contained 20-50% of total Hg in the <0.5 µm size fraction, while terrestrial and river sediments only contained 0.5-3.0% in this fraction. X-ray absorption spectroscopy revealed that metacinnabar (beta-HgS) was the main mercury species in marine sediment, while organic Hg-thiol (Hg(SR)(2)) was predominant in terrestrial sediment. Single-particle inductively coupled plasma time-of-flight mass spectrometry analysis indicated that half of the Hg in the <0.5 µm size fraction of marine sediment existed as individual nanoparticles.

Summary: The study focused on the seasonal cycling of mercury and methylmercury in vegetated sediments in the Dongtan wetlands of the Yangtze River Estuary, as well as the potential health risk of mercury in estuarine wetlands. The results revealed significant differences in the seasonal variations of total mercury and methylmercury, with the activity of methylating bacteria identified as a major contributor to elevated methylmercury levels. It was also found that the addition of mercury greatly increased the production of methylmercury, even under suboxic conditions, indicating a long-term health risk in the wetlands.

Summary: Sediment management is an important aspect of reservoir operation. A study on six reservoirs found that sediments in reservoirs tend to accumulate a variety of metal(loid)s, with fine particles being preferentially deposited. The leaching of metals from catchment soils also contributes to the enrichment of metals in stream sediments, especially in forested areas with weakly acid parent material.

Summary: The bioaccumulation potential of spherical and rod-shaped CuO nanomaterials in rainbow trout was evaluated. The shape and exposure route of the nanomaterials affected uptake and elimination. Despite higher dietary exposure concentrations, similar Cu body burdens were observed via water exposure for rod-shaped CuO nanomaterials. Therefore, careful consideration of the most relevant exposure route is needed when testing bioaccumulation of nanomaterials.

Summary: Climate warming and tropospheric ozone (O-3) are threats to plant species in Mediterranean mountains. This study examines the sensitivity of four Mediterranean perennial grasses to O-3 and temperature. Results show that water use efficiency and foliar nutrient composition are greatly affected by climate warming and O-3. Furthermore, these environmental factors can modify the adaptation capacity of Mediterranean grass species to global change. Air pollution should be considered as a driving factor of biodiversity changes in Mediterranean grassland habitats.

Summary: Graphene-based materials can be obtained on a large-scale level by chemical methods for oxidation of graphite to obtain graphene oxide (GO), in combination with thermal and laser-based reduction methods to produce reduced graphene oxide (rGO). The thermal reduction methods produce high specific surface area, suitable for volumetric energy applications, while the laser reduction methods achieve localized reduction and are ideal for microsupercapacitors in flexible electronics. The characteristics of the fabricated rGO samples were analyzed and compared using various chemical and structural characterization techniques.

Summary: This study evaluates the feasibility of obtaining graphene oxide (GO) and reduced graphene oxide (rGO) using different experimental conditions and methods. The findings suggest that the oxidation degree of GO can greatly influence the subsequent reduction process. The combination of solvothermal treatment and chemical reduction can significantly improve the C/O ratio and enhance the structural properties of rGO. Furthermore, rGO obtained from Tour method exhibits higher surface area and pore volume compared to Hummers method, making it more suitable for applications requiring high surface area.
