Potential Health Impact of Microplastics: A Review of Environmental Distribution, Human Exposure, and Toxic Effects

Microplastics are ubiquitous in the global environment. As a typical emerging pollutant, its potential health hazards have been widely concerning. In this brief paper, we introduce the source, identification, toxicity, and health hazard of microplastics in the human. The literature review shows that microplastics are frequently detected in environmental and human samples. Humans are potentially exposed to microplastics through oral intake, inhalation, and skin contact. We summarize the toxic effects of microplastics in experimental models like cells, organoids, and animals. These effects consist of oxidative stress, DNA damage, organ dysfunction, metabolic disorder, immune response, neurotoxicity, as well as…
