Summary: Water pollution is a global issue that threatens human health, particularly the safe supply of drinking water. Natural zeolites have shown promise in effectively removing heavy metals from contaminated water sources. This review examines the application of different natural zeolites for removing heavy metals such as arsenic, cadmium, chromium, lead, mercury, and nickel. Various chemical modifications of natural zeolites, as well as their sorption capacities and properties, are analyzed and compared. Clinoptilolite, in particular, is the most commonly used natural zeolite for heavy metal removal, demonstrating effectiveness against a range of heavy metals.

Summary: Many industries discharge wastewater containing heavy metals, which must be treated to remove the pollutants. Activated carbon adsorption is commonly used but is expensive, leading to research on low-cost alternatives like zeolites. Among them, clinoptilolite shows high selectivity for heavy metal ions, especially cadmium.

Summary: The adsorption of Cd2+ and Co2+ onto alginic acid (AA) was studied using density functional theory (DFT) calculations. Experimental and theoretical investigations were conducted to assess the adsorption of these heavy metals onto AA. The DFT calculations confirmed higher Co2+ adsorption and stronger affinity for Co2+ compared to Cd2+. Batch adsorption experiments using brown algae further verified the accuracy of the DFT calculations and demonstrated the remarkable potential of AA in removing heavy metals.

Summary: Chemically modified silica monolith particles were prepared for the adsorptive removal of lead (II) ions from aqueous medium. The adsorbent showed an adsorption capacity of 792 mg/g for Pb(II) ions, with a 98% adsorption rate under optimal conditions of pH 5, 0.4 g/L adsorbent dose, 500 mg/L Pb(II) ion concentration, and 1 hour adsorption time. The adsorption data fitted well with Freundlich and Langmuir isotherm models, and the adsorption process followed a pseudo second-order kinetic model, suggesting spontaneous and exothermic adsorption.

Summary: This study investigated the nano-scale spatial distribution of natural organic matter (NOM) on iron (hydr)oxides surfaces and its impact on oxyanion and metal cation adsorption. The results showed significant deviations between the MSM and NOM-CD models for oxyanions due to the competitive effect of NOM binding to oxides. Conversely, for metal cations binding mainly to NOM, the influence of NOM-mineral interaction on adsorption was minimal, resulting in similar results between the two models.

Summary: Two environmentally friendly materials (LGP and GBP) were successfully synthesized from local resources in Cameroon and their potential for removing Ni(II) and Co(II) from aqueous solutions was investigated. LGP had a higher specific surface area than GBP, but GBP exhibited stronger adsorption capacity, possibly due to the presence of negatively charged groups in its structure. LGP fitted well with Langmuir and Dubinin-Radushkevic models, while GBP was best described by the Freundlich model.

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.

Deterministic processes dominate the assembly of mesopelagic plastisphere microbial communities, while stochastic processes shape the assembly of bathypelagic microbial communities. The relationships between microorganisms in the mesopelagic layer are more complex and stable, with Proteobacteria and Actinobacteriota playing important roles.
