Summary: This study investigated the early-stage response of six lab-scale biogas bioreactors fed with different amounts of a sulfaterich organic agro-industrial effluent. The results showed that the yield of hydrogen sulfide (H2S) transitioned from transient to steady state within 2 weeks for all conditions. Additionally, volatile sulfur compounds (VSCs) such as methanethiol (MeSH) and dimethyl sulfide (DMS) were generated at high sulfate loads. Changes were observed in the microbial community structures, with a higher abundance of genes involved in the dissimilatory sulfate-reduction pathway in high loaded sulfate bioreactors. Principal component analysis (PCA) and correlation analyses revealed strong relationships between H2S, VSCs, and the microbial community.

Summary: Algae decay is an important process that affects environmental variables and emissions of volatile sulfur compounds (VSCs) in eutrophic lakes. The emissions of VSCs, including hydrogen sulfide, methanethiol, carbon disulfide, and dimethyl sulfide, increase with algae biomass and eutrophic levels. Algae decay significantly increases the contents of total sulfur and total carbon in sediments. The emissions of VSCs during algae decay are influenced by environmental variables rather than the direct influence of algae decay.

Summary: This study investigated the distribution of major volatile organic sulfur compounds in the Changjiang Estuary and the East China Sea, estimating their sea-to-air fluxes. The results suggest that VSC distribution is influenced by environmental and biological factors, with CS2 potentially linked to phytoplankton growth.

Summary: This study investigated the emissions of methane (CH4) and volatile sulfur compounds (VSCs) from different eutrophic regions of Lake Taihu. The study found that CH4 emissions increased with eutrophic levels and temperature, and H2S and CS2 were the dominant VSCs emitted from the lake. The relative abundance of Cyanobacteria and the algal growth promoted VSC emissions, which had a positive correlation with CH4 oxidation potential. Controlling algae growth could be an effective way to mitigate CH4 and VSC emissions from freshwater lakes.

Summary: Intra-oral halitosis is usually caused by volatile sulfur compounds produced by tongue microbiota. This study revealed that halitosis-free individuals had higher activity of Streptococcus, Veillonella, and Rothia, while halitosis was associated with Prevotella, Fusobacterium, and Leptotrichia. Additionally, the gene expression profiles showed differences in genes related to L-cysteine and L-homocysteine synthesis and cysteine degradation.

Summary: Seaweeds are nutrient-rich and consuming them can provide important health benefits. However, the flavor of seaweed is important for consumer acceptance, and volatile compounds play a key role. This article reviews the extraction methods and composition of volatile compounds from various seaweed species. Research shows that these compounds mainly consist of aldehydes, ketones, alcohols, hydrocarbons, esters, acids, sulfur compounds, furans, and other compounds in small amounts.

Summary: This study investigated the temporal and spatial distributions of VOSCs in Yangcheng Lake and found that they are higher in summer and autumn, with a hotspot in the western region. There was a positive correlation between VOSCs and phytoplankton biomass. Additionally, the study found that the presence of most algal phyla, except those with low biomass, had a positive effect on VOSCs' concentration.

Summary: Selenium-binding protein 1 (SELENBP1) acts as a methanethiol oxidase (MTO) in humans, converting methanethiol to hydrogen peroxide, hydrogen sulfide, and formaldehyde. Copper ions are essential for this MTO activity, as demonstrated by mutagenesis studies. Selenium binding, on the other hand, is not required for MTO activity. SELENBP1 ortholog SEMO-1 in the nematode C. elegans also requires copper ions for MTO activity. SELENBP1 degrades volatile sulfur compounds (VSCs), including methanethiol, suggesting its role in mitigating malodors.

Summary: Sediment dredging can effectively reduce organic matter and total nitrogen in sediments, improve the redox environment at the sediment-water interface, and slow down nitrogen cycle processes. However, the input of settling particles enriched in fresh organic matter and nitrogen can accelerate the recovery of nitrogen cycle processes and reduce variation in the nitrogen budget after dredging.

Summary: Fe-based materials used for P adsorption are often limited by increased Fe lability, but Fe in drinking water treatment residue (DWTR) shows stable P adsorption abilities. Compared to FeCl3 and Fe-2(SO4)(3), Fe in DWTR is relatively stable under the effects of organic matter, sulfides, and anaerobic conditions. The addition of DWTR increases oxidizable Fe in sediment and stabilizes Fe distribution, enhancing Fe stability for environmental remediation.

Summary: This study found through indoor simulation experiments that temperature is an important factor influencing algae-induced black blooms, and dredging and capping with clean soil can suppress blackening and odor formation in water bodies to some extent. The control effect of dredging on algae-induced black blooms is superior to that of capping with clean soil.

Summary: This study investigated the spatial and temporal variations of methane and carbon dioxide in the Northwest Bay of Lake Chaohu, China, which experiences frequent algal blooms. The results showed that methane concentration decreased significantly during warm seasons when algal blooms occurred, while carbon dioxide did not change substantially. River mouths acted as hotspots for carbon dioxide. The findings suggest that frequent algal blooms can absorb more carbon dioxide and release methane, making lakes an important part of the carbon budget and greenhouse gases emission.

Summary: The study reveals that the Daheiting Reservoir is faced with severe internal nutrient loadings, with significant spatiotemporal variations in nitrogen and phosphorus fluxes. The water discharge from the upstream reservoir is the dominant source of nitrogen and phosphorus, while internal phosphorus loading also contributes significantly to eutrophication.

Summary: In order to understand the distribution of nutrients, such as phosphorus (P), in eutrophic sediments, this study used the colorimetric diffusive gradients in thin films (DGT) methodology to analyze the labile P in the sediment-water interface of Lake Nansi. The results showed that the labile P concentrations in the sediment profiles of Lake Nansi exhibited significant spatial variations, with excessive P pollution increasing the concentrations. Furthermore, there was a strong positive correlation between labile P and iron, and labile P showed a strong upward mobility from the sediment to the overlying water. These results provide important information for the eutrophication processes in Lake Nansi.

Summary: Based on the analysis of eight heavy metals (As, Cd, Cr, Cu, Hg, Pb, Ni, and Zn) in sediments, a pollution pattern of heavy metals in a typical small- and medium-sized reservoir was derived. The results showed high levels of Cd, Hg, and As pollutants in the surface and upper sediment layers of the pre-dam area. Additionally, industrial, agricultural, and transportation activities were identified as the main sources of heavy metal pollution.
