Research Progress on Neurotoxicity of Microplastics Exposure in Different Stages of Life.

As a new type of environmental pollutant, microplastics have been increasingly receiving attention for their impact on human health. Current research indicates that microplastics can enter the human body through various routes and exert neurotoxic effects. This article reviews the types, sources, and exposure pathways of microplastics, with a focus on the neurotoxic effects and potential mechanisms of microplastic exposure at different life stages in humans (fetal, infant, adult, and elderly). This review provides a comprehensive understanding of the neurotoxicity of microplastic exposure and its implications for human health risk assessment and effective prevention strategies.
