Summary: This study experimentally investigated the stabilisation of soft, sensitive postglacial clay using lime-cement (50:50) as a reference and six alternative low-carbon binders. The results showed that four of the alternative binders exhibited similar or even higher strength levels compared to the reference binder after 28 days of curing. Similarly, the porosity and porosity distribution of the stabilised samples with alternative binders were comparable to the samples with the reference binder. In conclusion, the inclusion of alternative and side streams material in deep soil mixing has the potential to be a more ecological solution for soft clay improvement.

Summary: In this study, a slag soil hardener (SSH) developed by Wuhan University, China, was used in combination with different additives to improve the treatment effect and immersion stability of expansive soils. The experimental results showed that the combination of SSH and quicklime had the best improvement effect on expansive soils, reducing the free expansion rate and increasing the compressive strength. Analysis of the samples' characteristics and structure revealed that SSH reduced the proportion of montmorillonite and enhanced the mechanism of ion exchange, soil particle connection, and coating protection.

Summary: The use of potassium-rich wood ash (KRWA) as an environmentally friendly alternative to calcium-based materials in treating dispersive clay has shown promising results. This study found that 10% KRWA content is the optimal amount, reducing dispersion and sodium content significantly and improving the workability and load-bearing capacity of the treated clay. The physio-chemical analysis revealed the processes of ion exchange, agglomeration, and flocculation, followed by the formation of cementitious gels. Cost-based analysis also showed that KRWA is a more economical option for highway/road applications.

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.
