Abstract Polypropylene (PP) disposable face masks (DFMs) are essential for limiting airborne infectious diseases. This study examines the behavior of DFMs under three scenarios: i) exposure to natural environment; ii) simulated high-energy aquatic environments through an abrasion test; and iii) incorporation into cement-based mortars. In weathering experiment, after 117 days, exhibited photodegradation, resulting in chemical alterations carbonyl hydroxyl groups. degradation led breakdown polymer release microplastics nanoplastics. Controlled tests, conducted a Denver ball with water, sand, ceramic balls 2 hours, confirmed that water is critical factor fiber from DFMs. These tests resulted 0.26 g PP fibers 20 (weighing 62 total) diameter µm. Weathering indicated rapid nanoplastics, underscoring importance pursuing actions like reuse. Ecotoxicological revealed leachates DFM-incorporated mortars showed no adverse effects on Daphnia magna or Selenastrum capricornutum, unlike reference mortar, which caused substantial toxicity magna. Incorporating promising potential, as by favorable ecotoxicity leaching test results.

Microplastics (MPs) are emerging pollutants that constitutes a very serious environmental nuisance and menace to the globe in last decade. The damages from MPs include ecological imbalance of marine environment, flora, fauna these yet be understood African environment. sustainable development goals 14 15 (SDGs #14 #15) seek address challenges combating sustainability terrestrial lives respectively. Understanding pollution dynamics environment is crucial globally particular Africa soon. Hence, it imperative arrest this challenge as swiftly possible before collapse entire biomes. have been detected several matrices; soil, air, aquatic environments, plants, fishes, animals, humans. Their different source routes: ingestion, inhalation, dermal contact contribute an adverse effect (toxicity) all spheres life. To humans, limits their movement, leads shedding scales, inhibits growth, suppresses immune system, causes inflammation, coagulation, also blood cell toxicity among others, on long-run mortality was noted review. There physical, chemical biological transformation microplastics age, leading toxicity, mobility, great interaction. This has contributed high MP intake by fish other animals. For reason, researchers should delve into simpler cheaper ways analyzing its presence develop remediation strategies curb

Carbendazim (CBZ), as a highly effective benzimidazole fungicide, has good control effect on various crops caused by fungi. However, excessive use of CBZ in water, atmosphere, soil, and serious effects. The efficient degradation is an way to reduce its toxic effect. In this work, the type S-scheme Ag/AgBr/BiOBr heterojunction photocatalyst was effectively prepared simple one-step solvothermal situ method first applied mineralization CBZ. effects molar ratio AgBr BiOBr, catalyst dosage, concentration, pH value original solution, inorganic salt ions photocatalytic performance were comprehensively studied. results showed that, under visible light irradiation, 0.9-Ag/AgBr/BiOBr (0.9-AAB) exhibited best (88.9%) against concentration at 10 mg/L solutions with 10. also 7. After 90 min, efficiency reached 86.0%, corresponding TOC removal 84.0%. indicate that main active species are

The release of common medications and illegal drugs into the environment could be potentially harmful to ecosystem hamper behavior growth plants animals. These pollutants gain access water through sewage factory discharges have been found exceed safety limits in bodies. Therefore, there is an urgent need for improved wastewater purification systems. In this study, semiconductor-based heterojunction photocatalyst CuInS2/CeO2, synthesized a facile solvothermal process, was explored photocatalytic degradation ciprofloxacin, commonly used antibiotics. Studies on electronic properties revealed interfacial characteristics that were suitable enhanced charge carrier separation transport potential S-scheme transfer mechanism. achieved ∼90% efficiency CIP compared 60% 12% reported CeO2 CuInS2, respectively. This shows improvement activity, which results from heterojunction. Further investigation mechanism radical scavenging experiments identified •OH, O2•–, h+ as active species contributing catalyst's efficacy. Based X-ray photoelectron spectroscopy analysis, proposed suggested CuInS2/CeO2 findings indicate promising treating waste effluents pharmaceutical industry.
