LP-25 Assessing the impacts of oral exposure to microplastics on human health

Lifetime exposure to microplastics: From consumption to distribution in the body

AI summary · Read the abstract

This review pulls together existing research to estimate that over a lifetime, the average person swallows or breathes in about 224 million tiny plastic particles, and roughly 59% of that stays in the body rather than being flushed out. Exposure builds up most during adulthood, mainly from foods like edible oils and fruits, plus air, and these particles have been found lodged in various organs, including surprisingly high levels in ovarian fluid. While scientists are still figuring out exactly how this affects health, the sheer scale of lifelong buildup is a strong signal that reducing plastic exposure, especially in food and packaging, deserves serious

Human Exposure to Dietary Microplastics and Health Risk: A Comprehensive Review

AI summary · Read the abstract

This comprehensive review examines human dietary exposure to microplastics through bottled water, seafood, packaged foods, and crops grown in plastic-mulched soils, cataloging toxicity mechanisms including immune disruption, gastrointestinal damage, and developmental cytotoxicity, with MPs shown to transfer via placenta and breast milk. The multi-pathway exposure evidence reviewed here highlights that microplastic ingestion is a universal human experience beginning before birth, with plausible health consequences that demand urgent investment in mechanistic in vivo research.

Toxicological Effects of Ingested Microplastics on Human Health

AI summary · Read the abstract

Researchers reviewed the toxicological effects of ingested microplastics on human health, examining how these ubiquitous particles accumulate in the gastrointestinal tract and may cause inflammation, oxidative stress, and potential systemic harm across multiple organ systems.
