Environmental exposure to microplastics: An overview on possible human health effects
Summary
This review examines the potential health effects of human exposure to microplastics through ingestion, inhalation, and skin contact. Researchers found that microplastic exposure may cause oxidative stress, inflammation, and immune system disruption, with the body's inability to break down synthetic particles potentially leading to chronic inflammation. The study emphasizes that while evidence of harm is growing, microplastic toxicity varies greatly depending on particle properties, concentration, and individual susceptibility.
Microplastics are ubiquitous environmental contaminants leading to inevitable human exposure. Even so, little is known about the effects of microplastics in human health. Thus, in this work we review the evidence for potential negative effects of microplastics in the human body, focusing on pathways of exposure and toxicity. Exposure may occur by ingestion, inhalation and dermal contact due to the presence of microplastics in products, foodstuff and air. In all biological systems, microplastic exposure may cause particle toxicity, with oxidative stress, inflammatory lesions and increased uptake or translocation. The inability of the immune system to remove synthetic particles may lead to chronic inflammation and increase risk of neoplasia. Furthermore, microplastics may release their constituents, adsorbed contaminants and pathogenic organisms. Nonetheless, knowledge on microplastic toxicity is still limited and largely influenced by exposure concentration, particle properties, adsorbed contaminants, tissues involved and individual susceptibility, requiring further research.
