Human exposure to micro- and nanoplastic: biological effects and health consequence
AI summary Read the abstract
This review summarized the biological effects and health consequences of human exposure to micro- and nanoplastics, covering routes of uptake (ingestion, inhalation, dermal), cellular toxicity mechanisms, and systemic health risks identified in recent experimental and epidemiological studies.
Microplastics and nanoplastics are significant contributors to pollution as a consequence of increased plastic manufacturing and consumption, which has resulted in a worldwide environmental crisis. These small plastic particles (microplastics and nanoplastics with diameters less than 5 mm respectively 100 nm) originate from a wide range of sources, including packings, synthetic textiles, personal care products, and medical and laboratory consumables. The environmental effects and potential health hazards linked with microplastics and nanoplastics exposure are addressed in this review. Research has demonstrated a link between these plastic particles and human digestive, reproductive, respiratory, endocrine and cardiovascular pathologies. Microplastics and nanoplastics have the potential to be chronically detrimental given that they accumulate in human tissues and organs and are small enough to slip through cell membranes. In hopes of fully comprehending the mechanisms of toxicity and long-term consequences of exposure to microplastics and nanoplastics on human health, further research is urgently required. Policies that reduce the production and consumption of plastics and improve waste management practices are essential to combating plastic pollution.

This review covers how micro- and nanoplastic particles enter the human body through ingestion, inhalation, infusion, and skin absorption, distribute to virtually all tissues and organs via the circulatory system, and cause health impacts including inflammatory responses, cellular damage, and endocrine disruption.
Micro- and Nanoplastics on Human Health and Diseases: Perspectives and Recent Advances
AI summary Read the abstract
This review provides a comprehensive overview of how micro- and nanoplastics enter the human body through ingestion, inhalation, and skin absorption, and how they can then travel through the bloodstream to reach virtually every organ. Researchers summarize evidence that these particles can trigger inflammation, oxidative stress, and disruption of hormonal and immune functions. The study emphasizes that the ability of these particles to cross biological barriers and accumulate in tissues makes understanding their long-term health effects an urgent research priority.
