Summary: This study investigated the effects of SDBS, Tween 20, and their mixtures on the depuration of adsorbed anthracene and fluoranthene on Kandelia obovata leaf surfaces. The results showed that the microstructures of the leaf wax were destroyed by the surfactants at or above their CMC, leading to a decrease in the volatilization rate of the PAHs. Additionally, the photolysis rate of the PAHs decreased with SDBS but increased with Tween 20 and their mixtures at or above their CMC, suggesting that the surfactants influenced the light absorption behavior of the leaf wax. Therefore, the effects of the surfactants on the depuration of the PAHs were dependent on both the surfactant properties and the micro-environment of the substrates.

Summary: Snow acts as an ideal scavenger of polycyclic aromatic hydrocarbons (PAHs), leading to the accumulation of a large amount of PAHs in snowpacks. However, the fate of PAHs in snow, especially in the context of global climate change, is still unclear. This study investigated the photolysis of 16 priority PAHs listed by the US EPA in snow samples in the field. The results showed that over 50% of PAHs were lost during 6 hours of photolysis, with high molecular weight PAHs being photolyzed faster than low molecular weight PAHs.

Summary: In this study, we conducted single-molecule spectroscopy at cryogenic temperatures to investigate the optical properties of graphene quantum dots (GQDs). We found that temperature has an effect on the spectral characteristics of GQDs, and we used density functional theory calculations to explain these observations. Additionally, we discovered that the vibrational features can serve as a unique fingerprint for identifying GQDs.

Summary: Plastic debris, especially microplastics (MPs), can bind with pollutants and be ingested by humans, increasing the health risks. This study investigated the adsorption and desorption behavior of polycyclic aromatic hydrocarbons (PAHs) on different types of MPs, and assessed the potential carcinogenic risk. The results showed that higher molecular weight PAHs were more easily adsorbed on MPs, with polyethylene (PE) having higher adsorption efficiency than polymethyl methacrylate (PMMA). The desorption experiments in a simulated digestive system revealed that the activity of digestive enzymes affected the desorption, with PMMA showing higher desorption efficiency than PE. Molecular dynamics simulation confirmed enzyme-induced desorption. Risk assessment indicated that PAHs desorption from PMMA posed a higher carcinogenic risk compared to PE. This study enhances understanding of the interactions between pollutants, MPs, and human health risks.

Summary: The presence of polycyclic aromatic hydrocarbons (PAHs) in wastewater, especially acenaphthene (ACN), has become a major concern due to their potential negative health effects. This study used activated carbon from oil palm leaves to remove ACN from wastewater through adsorption. The optimization of pH, activated carbon dosage, and contact time was conducted using response surface methodology (RSM) combined with central composite design (CCD). The results showed that pH 7, an activated carbon dosage of 2.62 g/L, and a contact time of 71.67 min were the optimal conditions for achieving a removal efficiency of 98.88%. The RSM model was found to be significant, allowing for the prediction and verification of the adsorption results.

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.
