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

Environments, Год журнала: 2025, Номер 12(1), С. 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.

Effects of Microplastics on Bioavailability, Persistence and Toxicity of Plant Pesticides: An Agricultural Perspective

Agriculture, Год журнала: 2025, Номер 15(4), С. 356 - 356

Опубликована: Фев. 7, 2025

Microplastic–pesticide interactions influence pesticide performance, soil health, and environmental safety. This review aims to comprehensively present the effects of microplastic–pesticide on bioavailability, persistence, toxicity, along with their agricultural implications pest control. It reviews more than 90 related articles from established scholarly databases. Most studies indicate that bioavailability decreases in presence microplastics due adsorption, which is frequently influenced by hydrophobicity (log Kow) pesticides surface area type microplastics. Higher log Kow results higher adsorption lower bioavailability. Aged have areas for thus reducing effectiveness systematic contact pesticides. Lower leads less former plants control infestation latter pests kill them directly. also increases persistence pesticides, as indicated extended degradation half-lives. However, some demonstrate biodegradable microplastics, especially aged ones, effect because they release when break down. Few how alter toxicity target organisms are available, but available ones point potentially crops beneficial organisms. Overall, highlights a significant negative may prompt application achieve desired level crop protection, bears cost consequences.

Microplastics in seagrass ecosystems: A review of fate and impacts

Research in Ecology, Год журнала: 2024, Номер unknown, С. 41 - 53

Опубликована: Авг. 1, 2024

Microplastics have been detected in seagrass ecosystems, raising concerns about their potential impacts on the ecological functions of seagrasses. Seagrass meadows are biodiversity hotspots as they provide habitats to diverse fish and invertebrates. They also play a crucial role nutrient cycling, capturing carbon, buffering coastal erosion. This review aims present fate microplastics ecosystems ecosystems. A total 66 scientific articles reviewed. The highlights that intercept microplastics, though relevant results currently inconclusive. Some attach epiphytes blades or while some accumulate sediment, causing enrichment meadows. Nonetheless, few studies did not observe such intercepting effects. Microplastic enrichment, where observed, could be due near-bed turbulent kinetic energy entraps denser sinking microplastics. can directly affect seagrasses by blocking light transfer, affecting shoot leaf turnover, degenerating root oxidative stress. However, study Zostera marina L. found short-term exposure significantly impact bicarbonate utilization photosynthetic efficiency. additives, particularly bisphenol reduced chlorophyll caused peroxide accumulation Cymodocea nodosa. presence biodegradable plastics sediment might alter distribution interaction species. Seagrasses affected indirectly through but more needed confirm this. Desorption pollutants sorbed negatively Further research focus microplastic ecosystem processes therein, including cycling. Disintegration-oriented techniques alternatives conventional two strategies mitigate prevalence environment.
