Plastic production and plastic pollution have a negative effect on our environment, environmental justice, climate change. Using detailed global regional plastics datasets coupled with socioeconomic data, we employ machine learning to predict that, without intervention, annual mismanaged waste will nearly double 121 million metric tonnes (Mt) [100 139 Mt 95% confidence interval] by 2050. Annual greenhouse gas emissions from the system are projected grow 37% 3.35 billion CO 2 equivalent (3.09 3.54) over same period. The United Nations treaty presents an opportunity reshape these outcomes. We simulate eight candidate policies find that just four could together reduce 91% (86 98%) gross plastic–related one-third.

Nano/micro-plastic, an invisible threat getting into the brain

Chemosphere, Год журнала: 2024, Номер 361, С. 142380 - 142380

Due to weather and working/operational conditions, plastic degradation produces toxic non-biodegradable nano microplastics (N/M-Ps, ranging from 10 nm 5 mm), over time these N/M-Ps have integrated with the human cycle through ingestion inhalation. These N/M-Ps, as serious emerging pollutants, are causing considerable adverse health issues due up-taken by cells, tissue, organs, including brain. It has been proven that can cross blood-brain barrier (via olfactory blood vessels) affect secretion of neuroinflammatory (cytokine chemokine), transporters, receptor markers. Neurotoxicity, neuroinflammation, brain injury, which may result in such scenarios a concern cause disorders. However, related pathways pathogenesis not well-explored but focus upcoming research. Therefore, this editorial, well-organized multidisciplinary research is required explore associated pathogenesis, leading mapping nano-enabled therapeutics acute chronic N/M-P exposure.

Using Insect Larvae and Their Microbiota for Plastic Degradation

Insects, Год журнала: 2025, Номер 16(2), С. 165 - 165

Опубликована: Фев. 5, 2025

Plastic pollution is one of the biggest current global threats to environment given that petroleum-based plastic recalcitrant and can stay in for decades, even centuries, depending on specific type. Since less than 10% all made recycled, other solutions (such as incineration or landfill storage) are pollutant methods, new, environmentally friendly needed. In this regard, latest biotechnological discovery topic capability insect larvae use polymers carbon feedstock. This present review describes most relevant information capable degrading plastic, mainly Galleria mellonella (Fabricius, 1798), Tenebrio molitor (Linnaeus, 1758), Zophobas atratus 1776), also adds new about commonly studied “plastivore” insects such termites. covers literature from very first work describing degradation by published 2014 way research available (till June 2024), focusing identification a wide variety plastic-degrading microorganisms isolated guts understanding potential molecular mechanisms take place.

First evidence of microplastics in human ovarian follicular fluid: an emerging threat to female fertility

medRxiv (Cold Spring Harbor Laboratory), Год журнала: 2024, Номер unknown

Abstract Plastic pollution is a pressing global issue, with over 400 million tons produced annually and projections of 1.1 billion by 2050. Microplastics (MPs), ranging from 5 mm to 1 µm, are pervasive in the environment. They found air, sea, freshwater, soils, food chains studies show that tiny MPs, smaller than 10 μm, can cross cellular membranes, posing potential health risks through oxidative stress, inflammation, immune dysfunction, neurotoxicity reprotoxicity. In recent years, research has shown microplastics have negative effects on female reproductive systems animals. However, there still lack evidence how accumulation affects human females. This study aimed examine presence ovarian follicular fluid 18 women undergoing assisted treatment whose samples were processed using patented method endorsed nationally internationally. particles <10 µm measured SEM EDX detection. Preventive measures taken avoid contamination during process. (dimensions µm) detected 14 out fluid, an average 2191 p/ml (0 - 7181p/ml) mean diameter MPs 4.48 (3.18-5.54 µm).

Impacts of micro- and nanoplastics on early-life health: a roadmap towards risk assessment

Microplastics and Nanoplastics, Год журнала: 2024, Номер 4(1)

Опубликована: Июль 2, 2024

Abstract Micro- and nanoplastics (MNPs) are ubiquitous environmental pollutants representing a concern for human health. MNPs have been detected in placentas, indicating that during pregnancy maternal exposure may lead to placental transfer foetal exposure, with potential adverse effects on early-life development. However, comprehensive risk assessment (RA) framework, specific is lacking. Here, we propose novel roadmap assist the development of an health RA MNPs. This designed based established chemical, mixture, particle, MNP strategies aligned standard components (problem formulation, hazard identification, characterisation, assessment, characterisation). We systematically work through these stages identify what needed progress impacts MNPs, including information missing, be used interim. While challenges such as complex physicochemical properties limited toxicity data at relevant levels, uncertainties related characterising exposures described elsewhere, our discusses how specifically impact significance presence biological samples factors influencing bioaccumulation transfer. Additionally, introduce new technology readiness levels methods detection matrices. Importantly, this review integrates broad scope into one document, providing unified resource. highlight requirements areas targeted research, dose-response relationships assessing By addressing gaps, aims advance robust ultimately enhancing understanding mitigation risks associated
