Microplastics are pervasive in the environment and linked to various toxic effects in models
In short: A review of existing literature found that microplastics are ubiquitous in the global environment and frequently detected in human samples. Researchers identified that humans may be exposed to these pollutants through inhalation, skin contact, and oral intake.
By synthesizing evidence from experimental models such as cells, organoids, and animals, the review observed effects including oxidative stress, DNA damage, and organ dysfunction. It also noted associations with metabolic, immune, neurotoxic, and reproductive toxicity.
While epidemiological evidence suggests a potential link between exposure and various chronic diseases, the review highlights that significant gaps remain in current toxicity research.
Why it matters: Microplastics are widespread pollutants that may impact health through multiple biological pathways, though research gaps remain.
