Morphological and Chemical Characteristics of Microplastics in Surface Water of the Vaal River, South Africa

Environmental Processes, Journal Year: 2024, Volume and Issue: 11(1)

Published: March 1, 2024

Abstract Microplastics research in South Africa has focused on marine and coastal areas, with limited studies reporting microplastics freshwaters. To address this gap, we conducted study to investigate the presence, abundance, physical characteristics, chemical composition of surface water Vaal River, one most important freshwater systems Africa. Twenty-two samples were collected along 60 km middle part river using a 55 μm plankton net. Samples treated by acid digestion, MPs separated density separation. Physical identification was performed Nikon stereomicroscope, identified Raman spectroscopy. observed all 0.13 2.52 particles/m 3 concentrations. ranged size from 0.06 – 4.95 mm, more than 89% less 2 81% fragments (39%) fibers (42%). numerous colours, which green, black, blue dominant, representing 22%, 19%, 18%, respectively. Chemical analysis revealed polymer types as high-density polyethylene (HDPE), polypropylene (PP), low-density (LDPE). In addition, two colourants, pigment yellow 83 carbon detected. This provides new data microplastic occurrence characteristics River system offers baseline for future monitoring. Our findings confirm that is under real threat contamination, could impact its role significant Highlights • prevalent River. Fibrous, small-sized, coloured abundant. Polymers HDPE, LDPE, PP.

Arena ice quality and perspectives on optimizing performance and addressing emerging challenges

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: April 19, 2025

Maintaining optimal ice surfaces in arenas is essential for ensuring athlete performance and safety sports such as hockey, figure skating, curling. This study combines expert survey responses from 55 North American arena managers with existing literature to identify best practices managing conditions. Key factors, including temperature, humidity, thickness, water quality were examined areas needing empirical validation. While opinions offer valuable insights, controlled experiments are necessary determine how compressive strength, friction, Total Dissolved Solids (TDS) influence performance. Lower temperatures improve strength durability while slightly warmer better grip skating. humidity between 40% 50% aligns industry guidelines, balancing friction limiting frost formation sublimation. Water plays a critical role, yet conflicting recommendations highlight the need further research TDS levels. Additionally, emerging contaminants microplastics PFAS pose environmental concerns that warrant monitoring. Future should bridge gap knowledge scientific evidence refine promote sustainable operations.
