Summary: This study compared the environmental impacts of four typical propylene production routes in China using the life-cycle assessment methodology. The results showed trade-offs across nine environmental dimensions, making it difficult to rank the environmental advantages of each production route. Raw materials consumption was found to dominate the environmental burdens of the different routes, with the highest environmental loads in the coal to olefin process. The findings highlight the need for close attention to the feedstock shift in the propylene industry to promote environmental sustainability in the Chinese chemical manufacturing industry.

Summary: Organophosphate esters (OPEs) are commonly used as additives in various industries, and they can have long-lasting adverse effects on the environment due to their inability to chemically bond with materials. A meta-analysis of 58 articles containing 2676 samples from 10 countries revealed that China had the highest concentration of OPEs in water resources, with over 715 μg/L for certain OPEs. Monte-Carlo simulations showed that despite concentrations being within acceptable limits, 95% of the population may still be at risk.

Summary: This study evaluated the chronic health risks of residents living near a chemical accident site due to long-term exposure to formaldehyde. Results showed that inhalation exposure to formaldehyde did not cause harmful health impacts for all age groups, but exposure to soil containing formaldehyde did. This study is significant in assessing the residual and temporal concentration changes of a pollutant released in a chemical accident, reflecting the exposure characteristics of the toxic chemical.

Summary: Computational modelling of biological processes faces multiple challenges, such as identifiability, parameter estimation from limited data, informative experiments, and anisotropic sensitivity. Sloppiness, the property where model predictions are nearly identical over large regions in the parameter space, is a crucial but inconspicuous challenge. This study addresses critical unanswered questions about sloppiness, including its quantification, practical implications, and its impact on system identification.

Summary: China has implemented environmental regulations since the 1990s to combat PAH contamination. This study focuses on the Bohai region, using a model to simulate BaP concentrations from 1980 to 2020. BaP emissions were highest in 1990, with urban emissions peaking in 2010. BaP concentrations were higher in urban areas, posing cancer risks primarily through air inhalation. The implementation of environmental regulations has shown significant health benefits, with the biggest decline in cancer risk observed between 2010 and 2020.

Summary: Exploring the construction of heterostructures with bismuth oxybromide nano-units chemically implanted on indium vanadate particles to form composites resulted in extended visible light absorption range, accelerated charge transfer, and enhanced photocatalytic activity. The hierarchical core-shell structure provided large surface area for increased adsorption and degradation of pollutants, leading to the degradation of 92.59% of ciprofloxacin within 1 hour under visible light. The study also investigated reaction pathways using multiple models and explored the impact of various factors on adsorption and degradation of pollutants.

Summary: This study investigated the adsorption behavior of Pb(II) on natural-aged and virgin microplastics in different electrolyte solutions. The results showed that natural-aged microplastics had higher adsorption capacity for Pb(II) compared to virgin ones, and the addition of CaCl2 strongly inhibited the adsorption amount of Pb(II). The adsorption kinetics of Pb(II) were better fitted by the pseudo-second order model and Elovich equation and were slowed down greatly at higher ionic strength. The adsorption isotherm of Pb(II) onto microplastics affected by salt ions can be well described by Freundlich model, suggesting a multilayer and heterogeneous adsorption process. pH and fulvic acid in the electrolyte solutions significantly influenced the adsorption of Pb(II) due to changes in electrostatic interactions. Higher pH and ionic strength in different environmental water dramatically decreased the adsorption capacity onto microplastics. The adsorption mechanisms affected by salt ions mainly involve electrostatic interaction, surface complexation, and ionic exchange.

Summary: The mass production and daily use of plastic products have raised concerns about the potential toxicity of microplastics in the water environment. This study evaluated the effects of typical microplastics (PET) on the performance of activated sludge in membrane bioreactors (MBR). The accumulation of PET particles had adverse impacts on settleability and dewaterability of the sludge and also caused cell membrane damage. Furthermore, the abundance and diversity of microbial community in the activated sludge were reduced in the presence of PET. However, the physical scouring of particles mitigated membrane contamination in MBR.

Summary: Based on this study, two different sizes of silica materials (silica beads and Nano-silica) were used to encapsulate a QQ bacterial strain (Rhodococcus sp. BH4). The results showed that both QQ beads could resist high pressure, acid, alkali, salt, and EDTA buffer. After five months of use, both beads still had more than 70% QQ activity. In the lab-scale continuous MBR experiment, the transmembrane pressure (TMP) reaching 50 kPa in the experimental groups was more than 3 times that in the blank group, and the TMP contamination time was extended from 5 to 6 days in the blank group to 18-19 days. Among them, silica beads greatly improved the compressive strength of the beads and performed better in QQ.

Summary: Efficient visible-light-driven H2O2 production and antibiotic degradation are achieved using nitrogen-deficient modified polymeric carbon nitride (g-C3N4) as a catalyst. The N defects in the framework construct a giant internal electric field (IEF), inhibiting carrier recombination and promoting selective 2-oxygen reduction reaction (ORR). This study reveals the synergistic effects of the terminal cyano group and nitrogen vacancies over g-C3N4 for efficient H2O2 photogeneration photosynthesis.

Summary: Microbial quorum quenching (QQ) is an effective approach to mitigate biofouling in MBRs by reducing biopolymers production and improving sludge conditions. This study investigated the impact of aeration rate on the performance, membrane fouling, and energy consumption of QQ-MBR and C-MBR. It was found that QQ significantly mitigates biofouling, but the efficiency is lowest at high aeration intensity. QQ also reduces the content of SMP and EPS in sludge, with better performance at moderate aeration intensity. High aeration intensity results in the highest energy consumption, while QQ can optimize energy consumption by minimizing aeration intensity.
