Micro and Nanoplastics on Human Health and Diseases: Perspectives and Recent Advances
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.
Potential human health risks due to environmental exposure to nano- and microplastics and knowledge gaps: A scoping review
This scoping review surveyed existing research on the potential human health effects of exposure to micro- and nanoplastics. The evidence suggests these particles may contribute to oxidative stress, inflammation, and immune disruption, but the review highlights major knowledge gaps and calls for more studies specifically focused on human health outcomes.
A Systematic Review on the Impact of Micro-Nanoplastics Exposure on Human Health and Diseases
This systematic review summarizes existing research on how micro and nanoplastic exposure affects human health and may contribute to disease. The evidence suggests that these tiny particles can enter the body through food, water, air, and even cosmetics, potentially causing inflammation, oxidative stress, and disruptions to the immune and reproductive systems.
Do Engineered Nanomaterials Affect Immune Responses by Interacting With Gut Microbiota?
This review examined evidence that engineered nanomaterials including nanoplastics can indirectly modulate immune responses by altering gut microbiota composition, finding that while direct immunotoxicity is often mild, microbiome disruption provides an indirect pathway through which nanomaterials may impair host immunity.
Impact of Microplastics on Human health: Time for us to get attentive- before it’s too late
This paper reviewed the growing evidence on microplastic impacts on human health, covering ingestion, inhalation, and dermal exposure routes, and the potential for microplastics to cause inflammation, oxidative stress, and endocrine disruption. The authors argue the problem demands urgent regulatory attention.
Micro- and Nanoplastics on Human Health and Diseases: Perspectives and Recent Advances
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.
