Cellular and Animal Toxicities of Micro- and Nanoplastics

AI summary · Read the abstract

Researchers reviewed evidence from cell and animal studies on the toxic effects of micro- and nanoplastics, finding that these particles can cause inflammation, oxidative stress, and organ damage in laboratory models, raising concern about what chronic low-level human exposure might mean for long-term health.

An often-overlooked health issue: The potential adverse effects of microplastics on the human ocular health

Tiny plastic particles from air, cosmetics, and even contact lenses can land on the surface of your eyes, and this review of existing research suggests they may contribute to problems like dry eye, irritation, and inflammation of the cornea. While scientists are still figuring out exactly how harmful these particles are, the risk seems to depend on factors like plastic type and size, and can potentially be lowered by cutting down on plastic use and being mindful with contact lens care. It's a good reminder that microplastic exposure isn't just about what we eat or breathe, it may also affect the health of our eyes.

Microplastics and nanoplastics in human health: a comprehensive review of exposure pathways, cellular mechanisms, and toxicological implications

AI summary · Read the abstract

Researchers reviewed human exposure pathways to microplastics and nanoplastics through seafood, salt, drinking water, inhalation, and skin contact, examining how these particles cross biological barriers to reach organs and trigger oxidative stress, inflammation, and endocrine disruption with poorly understood long-term consequences.
