Global consumption led to increased and persistent plastic pollution in aquatic environments, affecting biota. Polystyrene (PS) is a synthetic polymer one of the most widely used plastics. This study aims investigate acute chronic effects PS microplastics on Cyprinus carpio using an adapted OECD methodology. For test, was tested different particle sizes (20, 200, 430 µm), each at concentrations 0, 1, 10, 100 mg PS/L. Mortality clinical signs were monitored after 96 h exposure. No recorded. In mix particles µm) total concentration 1.2 PS/L for 75-day fish Mortality, biometric parameters, physiological indices, antioxidant enzyme activities, including catalase (CAT), glutathione reductase (GRed), S-transferase (GST), 7-ethoxyresorufin-O-deethylase (EROD), lipid peroxidation (MDA), hepatic enzymes (alanine aminotransferase—ALT aspartate aminotransferase—AST), vitellogenin (VTG), acetylcholinesterase (ACh), assessed. Fish exposed exhibited 40% change hepatosomatic indices 75 days. Additionally, induced oxidative stress organs. CAT activity fourfold intestine, GRed thirtyfold gonads, GST doubled brain. also gills but not statistically significant compared control. Lipid observed kidney (twofold increase) detected intestine; however, these changes significant. EROD by 15% control group, indicating amplification expression. The ALT AST nine tenfold VTG 47%, ACh showed more than 80% inhibition brain muscle. Furthermore, overall protein expression intestine liver group. Our revealed incidence severity microplastic freshwater emphasized urgent need prevention, monitoring, mitigation measures combat pollution.

Macroplastic and Microparticle Pollution in Beach Sediments from Urias Coastal Lagoon (Northwest Mexico)

Toxics, Год журнала: 2024, Номер 12(6), С. 439 - 439

Опубликована: Июнь 18, 2024

This study investigates the occurrence and characteristics of macroplastic polymer microparticles in Urias coastal lagoon’s beach sediments, northwest Mexico. Coastal lagoons, productive vulnerable ecosystems, are impacted significantly by anthropogenic activities, leadings to their pollution various contaminants, including plastics. Our research involved sampling sediments from four sites within lagoon that were influenced different human activities such as fishing, aquaculture, thermoelectric power plant operations, industrial domestic wastewater discharge. methodology included collecting macroplastics sediment samples, followed laboratory analyses identify plastic debris’ size, shape, color, chemical composition. The results indicated a notable presence items (144), predominantly bags, styrofoam, caps made polyethylene (PE), polypropylene (PP), terephthalate (PET). mainly fibers, with cotton polyester most common polymers, suggesting significant contribution clothing-related waste. dominant colors blue transparent. High densities observed areas slower water exchange. findings highlight urgent need for better waste management practices mitigate preserving ecological economic functions.

Are microplastics a new cardiac threat? A pilot study with wild fish from the North East Atlantic Ocean

Global environmental contamination by microplastics (MPs) is a growing problem with potential One Health impacts. The presence of MPs in vital organs, such as the heart, particular concern, but knowledge still limited. goal present pilot study was to investigate heart wild specimens three commercial fish species (Merluccius merluccius, Sardina pilchardus, and Trisopterus luscus) from North East Atlantic Ocean. Heart samples 154 were analysed for MP content (one sample per fish). A total 44 recovered species. had varied chemical composition (5 polymers), shapes (4) colours (5). Differences profile among observed (p ≤ 0.05). Thirty (19%) their hearts, mean (±SD) concentration 0.286 ± 0.644 MPs/fish. S. pilchardus highest There no significant > 0.05) differences between M. merluccius T. luscus. These findings different biological ecological traits together literature data suggest that likely disseminated phenomenon. Therefore, further research on cardiovascular system its health effects very much needed.

Microplastic pollution is a global concern arising from the extensive production and use of plastics. The prevalence microplastics (MPs) in environment escalating due large part to excessive plastics various human-related activities. Consequently, animals are being exposed MPs through dietary intake, which poses significant health risks wild populations. objective study was assess concentration feces long-tailed macaques (
