The demand to address the ongoing environmental pollution has motivated the research community to develop novel methodologies for the degradation of the hazaradous pollutants. This study presents the development of an efficient and resilient Ag/AgCl nanocomposite catalyst supported on NiVO surfaces. The catalyst exhibited exceptional stability and photocatalytic performance in the degradation of methylene blue (MB) dye, as well as the reduction of 4-nitrophenol (4-NP) and Cr(VI) ions in presence of NaBH. A theoretical study has also been performed to investigate the role of silver in enhancing the stability and reactivity of the nanocomposite. This work demonstrates the potential of Ag/AgCl/NiVO as a promising material for addressing environmental pollution, offering a stable and effective solution for the degradation of hazardous pollutants.

Objectives: To assess changes in greenhouse gas emission rates associated with the use of anaesthetic gases (desflurane, sevoflurane, and isoflurane) in Australian health care during 2002-2022, overall and by state or territory and hospital type.
Study Design: Retrospective descriptive analysis of IQVIA anaesthetic gases purchasing data.
Setting: All Australian public and private hospitals, 1 January 2002 - 31 December 2022.

To date, environmental conditions have been enough to act as an effective barrier to prevent non-indigenous species from arriving and establishing in Arctic Canada. However, rapidly changing climatic conditions are creating more suitable habitats for non-indigenous species to potentially establish and become invasive. Concurrently, shipping traffic in parts of Arctic Canada has increased by over 250% since 1990, providing an effective vector for transporting non-indigenous species to the region.

Pipeline cleaning is essential for maintaining water quality and safeguarding public health within water distribution networks. Although ice slurry pigging is widely adopted due to its effectiveness and environmental advantages, challenges remain in accurately quantifying cleaning efficacy and optimising maintenance intervals. This study develops a stress-driven wall material removal model calibrated using field-measured turbidity data, allowing for a comprehensive assessment of cleaning effectiveness based on post-cleaning shear resistance.

Background: Ageing in place has been promoted in the Netherlands to encourage optimal functional ability (FA) and independent living among older adults. FA is likely dependent on intrinsic capacity (IC), a composite measure of an individual's mental and physical capacities-and its interaction with the physical environment in which people live. This study aimed to examine the association between IC and FA, as well as to explore how the physical environment may modify this relationship in older adults.

Despite China being the world's largest producer of non-ferrous metals, a comprehensive understanding of heavy metal pollution from this industry is still lacking. This study examines the spatial coupling between heavy metal (Cd, Hg, As, Pb, and Cr) emission hotspots in China's non-ferrous metal mining industry (NFMMI), non-ferrous metal smelting and processing industry (NFMSPI) and environmental media- sensitive hotspots (water body density, cultivated land concentration, and atmospheric PM2.5) to characterize the multi-media pollution risks.
