Environment International, Journal Year: 2024, Volume and Issue: 188, P. 108736 - 108736

Published: May 10, 2024

The presence of microplastics (MPs) is increasing at a dramatic rate globally, posing risks for exposure and subsequent potential adverse effects on human health. Apart from being physical objects, MP particles contain thousands plastic-associated chemicals (i.e., monomers, chemical additives, non-intentionally added substances) captured within the polymer matrix. These are often migrating MPs can be found in various environmental matrices food chains; health effects. In addition to attributes MPs, plastic surfaces effectively bind exogenous chemicals, including pollutants (e.g., heavy metals, persistent organic pollutants). Therefore, act as vectors pollution across air, drinking water, food, further amplifying posed by exposure. Critically, fragmentation plastics environment increases risk interactions with cells, available leach adsorb transfer pollutants. This review proposes so-called triple nexus approach comprehensively map existing knowledge interconnected particles, Based data, there large gap regard cumulative nexus. Each component known induce genotoxicity, inflammation, endocrine disruption, but about long-term inter-individual lacking. Furthermore, not readily excreted organisms after ingestion they have been accumulated blood, cardiac tissue, placenta, etc. Even though number studies MPs-associated impacts rapidly, this underscores that pressing necessity achieve an integrated assessment MPs' order address future gaps.

The micro(nano)plastics perspective: exploring cancer development and therapy

Molecular Cancer, Journal Year: 2025, Volume and Issue: 24(1)

Published: Jan. 24, 2025

Microplastics, as an emerging environmental pollutant, have received widespread attention for their potential impact on ecosystems and human health. Microplastics are defined plastic particles less than 5 millimeters in diameter can be categorized primary secondary microplastics. Primary microplastics usually originate directly from industrial production, while formed by the degradation of larger items. capable triggering cytotoxicity chronic inflammation, may promote cancer through mechanisms such pro-inflammatory responses, oxidative stress endocrine disruption. In addition, improved bring new perspectives to therapy, studies drug carriers underway, showing high targeting bioavailability. Although current suggest association between certain cancers (e.g., lung, liver, breast cancers), long-term effects specific still need studied. This review aimed at exploring carcinogenicity promising applications therapy provides important directions future research emphasizes multidisciplinary collaboration address this global health challenge.

A critical review of the adsorption-desorption characteristics of antibiotics on microplastics and their combined toxic effects

Environmental Technology & Innovation, Journal Year: 2024, Volume and Issue: 35, P. 103729 - 103729

Published: June 26, 2024

The interaction between microplastics (MPs) and pollutants is crucial for assessing the environmental risk of MPs. It necessary to pay attention adsorption/desorption behavior antibiotics on MPs due their potential role in antibiotic resistance. When MPs-loaded are ingested by organisms, they enter gastrointestinal tract undergo desorption, leading corresponding toxic effects. Existing literature primarily focuses adsorption behavior, while there a lack systematic generalizations desorption or combined effects organisms. Therefore, this article provides review mechanisms, biological tract. Desorption suggests that characteristics (aging hydrophobicity) components fluid (digestive enzyme species pH) can also have effect desorption. Moreover, summarizes induced MPs-antibiotics, demonstrating either enhance reduce plants, microorganisms, aquatic animals. Since methodological uniformity relevance natural environment main shortcomings existing literature, future research should focus actual water given region studying at gene, protein, metabolic levels. This direction expected provide valuable references insights evaluating antibiotics.

Genotoxicity of Microplastics on Living Organisms: Effects on Chromosomes, DNA and Gene Expression

Environments, Journal Year: 2025, Volume and Issue: 12(1), P. 10 - 10

Microplastic exposure has become unavoidable, leading to their presence in living organisms. One area of particular concern is the genotoxicity microplastics, which implications for reproductive health and cancer development. This review aims highlight genotoxic effects microplastics on different organisms, focusing impacts chromosomes, DNA, gene expression. More than 85 papers, primarily published last five years, have been reviewed. indicates that can cause clastogenesis aneugenesis at chromosome level. Clastogenesis results damage, while leads failures segregation without causing direct damage. Additionally, fracture damage DNA. These arise from (1) through interactions with associated proteins; (2) indirect due production reactive oxygen species (ROS) by oxidative stress induced microplastics. Microplastics trigger activation genes related inflammatory response, increased ROS production. Furthermore, they may alter expression other biological processes. The linked stem particles themselves chemicals, it appears be both size- dose-dependent.

Precocious puberty (PP) is a common pediatric endocrine disorder that affects children's growth and sexual development. Environmental pollutants, especially microplastics (MPs), may be an important triggering factors in PP.
