Microplastic (MP) contamination has become a pervasive global issue, affecting terrestrial and aquatic environments, its potential health hazards are of widespread concern. This review examined the intricate relationship between animal exposure to MPs their effects, revealing that MP affects broad spectrum species across habitats. Crucially, interspecies differences in ingestion, accumulation, responses emerge as central themes arising from various factors, including feeding behavior, physiology, ecological niches. The implications multifarious; animals may suffer physical harm, endure chemical adsorbed contaminants, provoke inflammatory responses, undergo behavioral modifications.

Unravelling the microplastic menace: Different polymers additively increase bee vulnerability

Environmental Pollution, Journal Year: 2024, Volume and Issue: 352, P. 124087 - 124087

Published: May 2, 2024

Microplastics (MPs) are growing and ubiquitous environmental pollutants represent one of the greatest contemporary challenges caused by human activities. Current research has predominantly examined singular toxicological effects individual polymers, neglecting prevailing reality organisms confronted with complex contaminant mixtures potential synergistic effects. To fill this gap, we investigated lethal sublethal two common MPs, polystyrene (PS - 4.8-5.8 μm) poly(methyl methacrylate) (PMMA 1-40 μm), their combination (MIX), on pollinating insect Apis mellifera. For each treatment, evaluated oral toxicity ecologically relevant higher concentration (0.5, 5 50 mg/L) analysed immune system worker survival. As activation can alter cuticular hydrocarbon profile honey bees, used gas chromatography-mass spectrometry (GC-MS) to investigate whether MPs lead changes in chemical foragers behavioural assay test such affect patterns social recognition, undermining overall colony integrity. The results indicate an additive negative effect PS PMMA bee survival response, even at concentrations. Furthermore, alterations cuticle profiles were observed both highest intermediate concentrations, being mainly responsible. Both exposure resulted a reduction abundance several compounds. Hive entry guards did not show increased inspection or aggressive behaviour towards exposed foragers, allowing them enter without treated differently from uncontaminated foragers. These findings raise concerns only for health but also entire colony, which could be risk if contaminated nestmates undetected, spread throughout hive.

Reimagining plastics waste as energy solutions: challenges and opportunities

npj Materials Sustainability, Journal Year: 2024, Volume and Issue: 2(1)

Published: Feb. 21, 2024

Abstract Recent statistics portray a stark reality, particularly highlighting the inadequate recycling measures and consequent environmental threats, most notably in developing nations. The global ramifications of plastic pollution are elucidated, specifically focusing on alarming accumulation regions such as “Great Pacific Garbage Patch” evolving waste management practices Southeast Asian countries. We emphasize significance Waste-to-Energy (W2E) Waste-to-Fuel (W2F) technologies, e.g., pyrolysis gasification, for converting difficult-to-recycle into dense-energy source. However, we identify critical gap current research: emission CO 2 during these processes. This perspective spotlights emergent capture utilization underscoring their role robust turnkey solution making W2E W2F methods more sustainable unleashing huge potential using plastics scientific community is urged to develop tailored solutions reducing emissions conversion approach promotes circular resource realizes socio-economic advantages advocating implementation economically disadvantaged regions.

Published: Feb. 11, 2025

The global crisis of plastic pollution, particularly involving microplastics (MPs) and nanoplastics (NPs), has profound ecological implications. Birds, serving as bioindicators, are especially susceptible to these pollutants. This systematic review synthesizes the current research on presence, distribution, impact MPs NPs avian species, alongside advancements in detection methodologies. have been identified over 200 bird species across 46 families, encompassing several ecosystems, from Antarctica Labrador, including Australia, China, South Europe. Seabirds such penguins, gulls, shearwaters exhibit a high burden tissues feces due fishing debris, while terrestrial face contamination urban agricultural sources. Depending their composition, can cause gastrointestinal damage, oxidative stress, bioaccumulation toxic chemicals, polyethylene polypropylene. However, challenges persist methodological inconsistencies, though advances spectroscopy flow cytometry offer improved accuracy. Addressing this pollution is vital for conservation ecosystem health, requiring international collaboration standardized protocols.

The accelerated growth of the electrical and electronic equipment market is a major driver behind increasing e-waste volumes worldwide. Although contains valuable resources, most remain unrecycled or improperly managed. Recycling efforts primarily focus on recovering metals, while plastic constituents overlooked. Furthermore, current recycling approaches have led to environmental contamination by hazardous materials. Recent for valorisation plastics demonstrated potential applications these materials their role in towards implementing more sustainable economy.
