Bioaccessibility of lead and cadmium in soils around typical lead-acid power plants and their effect on gut microorganisms.

Potentially toxic elements (Pb and Cd) contamination of soil can adversely affect human health. Moreover, these metal ions interact with the gut microbiota after entering the human digestive system. Based on the physiologically based extraction test and the simulator of human intestinal microbial ecosystem, the bioaccessibility of Pb and Cd in soils contaminated with lead-acid power plants was assessed.

Study on arsenic speciation, bioaccessibility, and gut microbiota in realgar-containing medicines by DGT technique and artificial gastrointestinal extraction (PBET) combine with simulated human intestinal microbial ecosystem (SHIME).

It is well-known that several Chinese patent medicines use realgar as a specific component. People are more aware of the health dangers associated with realgar since it includes arsenic. Previous research overstated the arsenic toxicity of realgar-containing Chinese prescription medications because little thought was given to the influence of arsenic bioaccessibility by gut microbiota.

Contrasting effects of a novel biochar-microalgae complex on arsenic and mercury removal.

Biochar and algae were commonly used as environmental-friendly adsorbents to treat wastewater contaminated with heavy metals. In the study, we used a biochar-microalgae complex of Coconut shell activated carbon (Csac) and Chlorella to evaluate and compare the adsorption ability of arsenic and mercury. The adsorption kinetic study showed that the adsorption efficiency of the biochar-microalgae complex for mercury was better remarkably than arsenic (about 74.

Improved effects of combined application of nitrogen-fixing bacteria Azotobacter beijerinckii and microalgae Chlorella pyrenoidosa on wheat growth and saline-alkali soil quality.

Soil salinization seriously affects crop yield and soil productivity. The application of bacteria and microalgae has been considered as a promising strategy to alleviate soil salinization. However, the effect of bacteria-microalgae symbiosis on saline-alkali land is still unclear.

Study on the mechanism of biochar loaded typical microalgae Chlorella removal of cadmium.

Coconut shell activated carbon (Csac) is one of the most widely used materials to remove cadmium (Cd) from contaminated water. A large diversity of microorganisms exists in various aquatic systems and may aid Cd removal by Csac. In this study, we explored the reactions of Csac with microalgae (Chlorella) in Cd-containing media.

[Surgical treatment of open fractures of the talus].

Objective: To evaluate the long-term outcomes of surgical treatment of open fracture of talus.

Methods: Sixteen patients with displaced open fractures of the talus, including 3 cases of type 1, 8 of type 2, 2 of type 3A, 2 of type 3B, and 1 of type 3C according to the Gustilo-Anderson classification system, 15 males and 1 female, aged 37.5 (21 - 48), were treated with open reduction and stable internal fixation within 6 - 8 hours after injury, and followed up for 3.
