Emerging contaminants (ECs) are a diverse group of unregulated pollutants increasingly present in the environment. These contaminants, including pharmaceuticals, personal care products, endocrine disruptors, and industrial chemicals, can enter environment through various pathways persist, accumulating food chain posing risks to ecosystems human health. This comprehensive review examines chemical characteristics, sources, varieties ECs. It critically evaluates current understanding their environmental health impacts, highlighting recent advancements challenges detection analysis. The also assesses existing regulations policies, identifying shortcomings proposing potential enhancements. ECs pose significant wildlife by disrupting animal hormones, causing genetic alterations that diminish diversity resilience, altering soil nutrient dynamics physical Furthermore, increasing health, hormonal disruptions, antibiotic resistance, disruption, neurological effects, carcinogenic other long-term impacts. To address these critical issues, offers recommendations for future research, emphasizing areas requiring further investigation comprehend full implications contaminants. suggests increased funding support development advanced technologies, establishment standardized methods, adoption precautionary regulations, enhanced public awareness education, cross-sectoral collaboration, integration scientific research into policy-making. By implementing solutions, we improve our ability detect, monitor, manage ECs, reducing risks.

Effect of microplastics deposition on human lung airways: A review with computational benefits and challenges

Heliyon, Год журнала: 2024, Номер 10(2), С. e24355 - e24355

Опубликована: Янв. 1, 2024

Microplastics have become omnipresent in the environment, including air we inhale, water consume, and food eat. Despite limited research, accumulation of microplastics within human respiratory system has garnered considerable interest because its potential implications for health. This review offers a comprehensive examination impacts stemming from on lung airways explores computational benefits challenges associated with studying this phenomenon. The existence can lead to range adverse effects. Research indicated that induce inflammation, oxidative stress, impaired function. Furthermore, small size allows them penetrate deep into lungs, reaching alveoli, where gas exchange takes place. raises concerns about long-term health consequences, such as development diseases translocation other organs. Computational approaches been instrumental understanding impact microplastic deposition airways. models simulations enable investigation particle dynamics, patterns, interaction mechanisms at various levels complexity. However, using methods presents several challenges. complex anatomy physiological processes require accurate representation models. Obtaining relevant data model validation parameterization remains significant hurdle. Additionally, diverse nature microplastics, variations size, shape, chemical composition, poses capturing their full behaviours toxicological

Characteristics and quantification of small microplastics (<100 µm) in seasonal svalbard snow on glaciers and lands

Journal of Hazardous Materials, Год журнала: 2024, Номер 467, С. 133723 - 133723

Опубликована: Фев. 10, 2024

Small microplastics (SMPs < 100 µm) can easily be transported over long distances far from their sources through the atmospheric pathways and reach even remote regions, including Arctic. However, these sizes of MPs are mostly overlooked due to different analytical challenges; besides, depositions, such as snow unknown. The spatial variability in bulk samples was investigated for first time distinct sites (e.g., glaciers) near Ny Ålesund, world-known northernmost permanent research settlement Svalbard Islands, better comprehend presence SMP pollution snow. Seasonal deposited tundra summits glaciers were also sampled. A sampling procedure designed obtain representative while minimizing plastic contamination, thanks rigorous quality assurance control protocol. SMPs' weight (µg L-1) deposition load (mg SMPs m-2) result being lower glaciers, where they may subject long-range transport. minimum length 20 µm, with majority less than µm. Regarding size distribution, there an increase deriving local input human scientific settlement. some polymers might site-specific relation that affect distribution at studied. Also, surface layer collected same evaluate during specific events, results confirmed higher compared glaciers. will enhance limited knowledge polar compartments processes. issue regions has been addressed by several working g, e.g., Arctic Council, since become a global priority. MPs, specifically SMPS, considered hazardous materials because have toxic effects additives pollutants adsorbed/absorbed on surface. Their role altering climate process ( ice/snow melting, ocean air circulation, enhancing ice nucleation, cloud formation) significantly ecosystems, biological communities implications entire food chain.

Microplastic fibres affect soil fungal communities depending on drought conditions with consequences for ecosystem functions

Environmental Microbiology, Год журнала: 2024, Номер 26(2)

Опубликована: Янв. 10, 2024

Abstract Microplastics affect soil functions depending on drought conditions. However, how their combined effect influences fungi and linkages with ecosystem is still unknown. To address this, we used rhizosphere from a previous experiment in which employed microplastic fibres addition factorial design, evaluated effects fungal communities. decreased richness under well‐watered conditions, likely linked to microplastics leaching toxic substances into the soil, root fineness. Under drought, by contrast, increased pathogen total richness, related positive properties, such as water holding capacity, porosity or aggregation. Soil was attribute most affected drought. altered relationships between point that many of them flipped negative disappeared. The mitigated individual (antagonism), suggesting changes conditions may alter action mode soil. Microplastic harmful can be while improvement properties alleviate

Role of Microplastics in Global Warming and Climate Change: A Review

Water Air & Soil Pollution, Год журнала: 2024, Номер 235(3)

Опубликована: Март 1, 2024

Abstract Microplastics (MPs) have become an important concern among scientists and policymakers all around the globe. Despite this, contribution of MPs to global warming climate change, a significant aspect issue, has been overlooked. Continuous greenhouse gas (GHG) emissions resulting in change long major issue with apparent consequences. Climate plastic crises are threatening our planet, co-occurrence both would be catastrophic. This article addressed links between microplastic pollution change; how contribute by interacting water, air, soil; recommendations address issues together. Throughout their lives, plastics emit GHG. water impede mitigation potential ocean different ways; they hamper photosynthesis carbon sequestration phytoplankton Blue Carbon Ecosystem. induce GHG from soil. Airborne aid cloud formation interfere atmospheric cooling. change–induced extreme events redistribute environment, causing increase vertically horizontally, which then aggravates situation feedback loop. The evidence acquired study implies that inextricably linked play vital role fueling change. bridges gap were previously regarded separately. Due linkages these intertwined challenges, integrated holistic research policy measures required concurrently.
