Research Background Global climate change, particularly global warming, has exerted immense pressure on the global carbon cycle. As a significant carbon sink, the ocean absorbs large amounts of carbon dioxide (CO₂), leading to ocean acidification, which adversely affects marine organisms reliant on carbonate minerals. Coastal wetlands, such as inte...
Iodine (I) is a trace element of significant importance to human health and the environment. It is a major component of human thyroid hormones, such as thyroxine (T4) and triiodothyronine (T3), directly influencing thyroid function. However, approximately 1.9 billion people worldwide are affected by Iodine Deficiency Disorder (IDD), with symptoms i...
Uranium (U) is a radioactive element widely present in the environment, primarily existing in its hexavalent (U(VI)) and tetravalent (U(IV)) oxidation states. Under oxidizing conditions, U(VI) is the dominant stable form, while under reducing conditions, U(VI) can be reduced to U(IV). This reduction process can occur through abiotic pathways (e.g.,...
Molybdenum (Mo) is one of the most abundant trace metals in the ocean, and its distinct behavior under different redox conditions makes it an effective indicator of paleoceanographic redox conditions. Particularly in anoxic and sulfidic environments, the speciation and behavior of Mo differ significantly from those in oxic environments. However, th...
Selenium (Selenium) is an essential trace element widely found in nature and involved in various biological metabolic processes. However, when selenium concentrations are too high, they can cause severe toxic effects on humans, animals, and the environment. Industrial activities, especially coal combustion in coal-fired power plants, are one of the...
Soil is the product of terrestrial biogeochemical processes and an essential foundation for human survival. Microorganisms endow soil with life properties and drive the biogeochemical cycles within it. Microorganisms play a crucial role in improving soil structure, enhancing fertility, controlling pollution, and responding to global climate change....
Iron (Fe) is one of the most abundant elements on Earth, widely present in soils and sediments, and participates in global carbon, nitrogen, and oxygen cycles. The redox reactions of iron play a crucial role in biogeochemical cycles, particularly in the processes of iron oxidation and reduction. Iron minerals, especially mixed-valent iron minerals ...
Hydraulic fracturing is a technique used to extract natural gas from unconventional reservoirs, but it generates large volumes of flowback and produced water. These waters contain complex mixtures of organic and inorganic constituents, particularly the solids associated with these fluids, which are often rich in iron (Fe), toxic organics, heavy met...
Academic Background The widespread use and improper disposal of chlorinated solvents (such as perchloroethylene and trichloroethylene) have led to severe contamination of soil and groundwater worldwide. These pollutants not only threaten groundwater security but may also affect human health through the food chain. Although traditional microbial red...
Academic Background With the growing threat of organic compounds to environmental pollution, studying the toxic responses of different aquatic organisms to these compounds has become crucial. Such research not only helps assess the potential ecological impacts of pollutants on the overall aquatic ecosystem but also provides significant scientific f...
