Summary: This study developed a mixed culture to improve the efficiency of metal recovery from spent LiCoO2 batteries. By using Fe2+ as a reductant in the presence of the mixed culture, cobalt and lithium could be leached efficiently, overcoming the issue of low leaching efficiency. Mechanism analysis revealed that the release of electrons by Fe2+ reduced refractory Co(III) to soluble Co(II), enabling effective metal extraction.

Summary: The recycling of Ni, Cd and Co from spent Ni-Cd batteries is crucial for preventing deficiency of these metals and protecting the environment. This study proposes a formic acid-assisted method for leaching and recovering valuable metals from the cathode and anode materials of spent Ni-Cd batteries. The experimental results and statistical analysis show that high leaching efficiencies of Cd and Co can be achieved at 80 degrees C and 2.5 h, while Ni leaching is optimized at 90 degrees C, 4 h and a 30 mL/g liquid/solid ratio. Moreover, the use of H2O2 as an oxidizing agent enables efficient leaching of metallic Ni.

Summary: The increasing demand for metals and the depletion of primary metallic resources pose significant environmental and societal challenges. Waste electrical and electronic equipment (WEEE) is increasing globally, with end-of-life electronic wastes containing valuable metals and harmful substances. Proper management and recycling of spent Li ion batteries is crucial to address environmental complications and promote sustainable resource management. Microbial technologies show promise in removing metal ions from WEEE with less cost and no addition of toxic chemicals, making them environmentally friendly alternatives to conventional methods. Biohydrometallurgy practices for leaching critical metals from waste lithium ion batteries and biotechnological methods for recovering these metals from aqueous streams are important areas of research in this field.

Summary: This review discusses the use of bioleaching processes for recovering metals from different types of spent batteries. By classifying batteries based on their chemical composition, the bacterial and fungal leaching methods for each type of battery are reviewed, and the research outputs and chemical and biological mechanisms are compared. The main bioleaching mechanisms found are the reactions of metals with metabolites, acid dissolution, and their combinations with oxidation-reduction reactions. The advantages and disadvantages of battery bioleaching are discussed, and it is noted that slow kinetics and low pulp densities hinder its commercial development.

Summary: This study reveals that chronic exposure to PM induces chronic inflammation and development of COPD by dysregulating NAD+ metabolism and subsequent SIRT1 deficiency in pulmonary macrophages. Activation of SIRT1 by resveratrol effectively mitigates PM-induced inflammation and COPD development. Targeting metabolic and epigenetic reprogramming in macrophages induced by PM is a promising strategy for COPD treatment.

Summary: Microplastic contamination in marine ecosystems poses a growing concern due to its trophic transfer and negative effects on marine organisms. This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.

Summary: This study measured the levels of phthalate metabolites in breast milk collected from mothers in southern China. The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.
