Microplastic pollution, a major global environmental issue, is gaining heightened attention worldwide. Marginal seas are particularly susceptible to microplastic contamination, yet data on microplastics in marine sediments remain scarce, especially in the Beibu Gulf. This study presents a large-scale investigation of microplastics in the surface sediments of the Beibu Gulf to deciphering their distribution, sources and risk to marginal seas ecosystems.

DASCO Inc, Centennial, Colorado, USA.
This study thoroughly investigated the adsorption of Congo Red (CR) dye onto various microplastics (MPs), including high-density polyethylene (HDPE), polyvinyl chloride (PVC), low-density polyethylene (LDPE), polypropylene (PP) and polyethylene terephthalate (PET). Initial adsorption capacities (q) revealed that HDPE had the highest value (21.90 mg/g), followed by PVC (4.

Background: Incidence of peripheral venous cannula (PVC) bacteraemia have been rising in a trust in the south-west of England, with a 267% increase noted over the 2022/23 financial year compared with the previous year.
Aim: To use a multimodal approach to reduce the incidence of PVC bacteraemia and improve patient safety.
Methods: The initiative consisted of an educational poster highlighting the severity of infection associated with PVCs alongside key prevention messages rooted in Trust policy.
Application of Post-Industrial Leather Waste for the Development of Sustainable Rubber Composites.
Polymers (Basel)
January 2025
Faculty of Engineering and Science, Sao Paulo State University (UNESP), Rosana 19274-000, SP, Brazil.
The substantial waste generated during the processing of hides and skins as well as at other stages of manufacturing is a recurring issue in the leather industry that this article attempts to address. To investigate the mechanical and thermal characteristics of the resultant composites, this study suggests using leather waste from the bovine leather industry, analyzes the tanning process, and assesses the viability of mixing this waste with natural rubber (TSR-20). Without the inclusion of leather waste, the resulting composites had exceptional tensile strength, surpassing 100% of rubber's strength.

Many test methods used in the assessment of construction products are characterised by poor precision, which is reflected in the discrepancies of results obtained by different laboratories. The test procedure for fungal resistance of natural particle-reinforced composite construction profiles has not been fully specified, which may lead to such discrepancies and erroneous utility assessment. In this study, the precision of the method and the influence of the mycelium removal on the fungal resistance were assessed based on the flexural strength and modulus of elasticity test results obtained for millet- and oat husk-reinforced PVC composites exposed to .
