Urbanization itself is a major and furthermost imperative contributor to the release of microplastics into environments. As cities grow develop, more plastic products are consumed discarded, resulting in increased pollution levels. Although researches on airborne (AMPs) urban regions scare, recent findings have shown high concentration them air residential areas. Textiles main source indoor ambiance, while traffic-related particles, textiles agricultural marine appear be responsible for polluting cities' outdoor atmosphere. Local metrological situation, topography physical features particles control behavior, distribution fate microplastics. Inhalation primary exposure route may induce toxicity respiratory tract. Understanding these factors crucial developing effective strategies mitigate their impact human health environment. Current work reviews published literature settings aiming at characterizing parent's materials, potential sources both spaces, possible impacts along with some further suggestions.

Sources, analysis, and health implications of atmospheric microplastics

Emerging contaminants, Год журнала: 2023, Номер 9(3), С. 100233 - 100233

Microplastics (MPs) are emerging environmental contaminants pervasive in the environment. Studies have revealed that majority of airborne MPs form fiber. Inhaled atmospheric adversely impact human health, causing inflammation and oxidative stress. Atmospheric may also carry hazardous chemical pollutants addition to heavy metals. Many research studies been conducted about MPs’ presence components, however questions identification remained unanswered. Based on mentioned gaps, this study examined sources abundance atmosphere their generation, accumulation, fate. The paper further evaluates current methods for identifying assessing health According findings, there flaws complexity assessment technical procedures, which challenges data comparability dependability. In order ensure reliability, needs be expressed using a unified standard methodology. Innovative well-established methods, strategies minimize impacts MPs, appropriate steps reduce global pollution required state MPs. It provides an overview MPs' characteristics, sources, transmission deposition mechanisms. Advances bacterial degradation, sunlight-driven photocatalysts, fuels, biodegradable plastics could revolutionize future reducing plastic pollution. Future should include more various aspects Despite several many regarding from perspectives COVID-19 One Health still need answered. This will help key stakeholders policymakers safeguarding public environment threats posed by

Human Exposure to Ambient Atmospheric Microplastics in a Megacity: Spatiotemporal Variation and Associated Microorganism-Related Health Risk

Environmental Science & Technology, Год журнала: 2024, Номер 58(8), С. 3702 - 3713

Опубликована: Фев. 15, 2024

Microplastics are found in various human tissues and considered harmful, raising concerns about exposure to microplastics the environment. Existing research has analyzed indoor occupational scenarios, but long-term monitoring of ambient atmospheric (AMPs), especially highly polluted urban regions, needs be further investigated. This study estimated environmental AMPs by considering inhalation, dust ingestion, dermal three functional zones within a megacity. The annual quantity was 7.37 × 104 items for children 1.06 105 adults, comparable with microplastic consumption from food water. Significant spatiotemporal differences were observed characteristics that humans exposed to, wind speed rainfall frequency mainly driving these changes. AMP green land spaces, which recognized as relatively low zones, public service residential zones. Notably, significant positive correlations between pathogenicity airborne bacterial community discovered. size immune-mediated disease risks brought microbes showed most relationship, where Sphingomonas might act potential key mediator.

Microplastics Aloft: A comprehensive exploration of sources, transport, variations, interactions and their implications on human health in the atmospheric realm

Earth-Science Reviews, Год журнала: 2024, Номер 255, С. 104864 - 104864

Microplastics (MPs), particles with a size <5 mm, are ubiquitous in water, soil, and atmosphere, have become highly discussed environmental issue. Although atmospheric MPs received less attention than soil their possible consequences being examined more depth. This study systematically reviews the sources, transport, distribution, variations of MPs, interactions other pollutants environment impact on human health based literature. The results show that been identified diverse settings such as urban, sub-urban, remote areas well indoor air. These airborne can originate from terrestrial sources like landfills, synthetic clothing, plastic manufacturing, use recycling activities, aquatic resulting bubble bursting. outdoor MP abundance was detected range 2 to 1159 MP/m2/day depositions 0 224 MP/m3 suspended samples, while significantly higher observed indoors ranging 22 760,000 0.4 1583 MP/m3. distribution characteristics affected by several factors urbanization, anthropogenic environments seasons. Atmospheric transport occurs through suspension, horizontal deposition processes greatly influenced morphology MP, wind speed direction, precipitation factors. path atmosphere is studied Lagrangian models conducting backward trajectory simulations estimate linear trajectories at sampling locations discern potential origin travel distance. also interact variety chemical microorganisms thus act vector for pollutant transport. toxicity may be increased release pathogens contaminants into environment, thereby increasing risk humans. Based study, it suggested further scientific research should focus standardization methods, mechanisms, ecological impacts. As could enter body various urgent physiological effects when exposed pollution.
