Neurotoxicity and Mechanisms of Microplastics and Nanoplastics Exposure in Terrestrial Mammals
Microplastics and nanoplastics (MNPs) pollution has become a serious environmental issue. MNPs can enter the human body through inhalation, ingestion, and skin contact, raising significant concerns about their potential risks to the nervous system. This paper reviews the studies on the neurotoxic effects of MNPs in terrestrial mammals, focusing on their possible toxic mechanisms. Studies have shown that MNPs can cause damage to the nervous system by inducing oxidative stress, inflammatory responses, and mitochondrial dysfunction. Additionally, the impact of MNPs on the gut-brain axis is considered a crucial mechanism leading to neurotoxicity. Despite current progress, there are still insufficient data and incomplete understanding of the neurotoxic mechanisms involved. Future research should enhance epidemiological studies on MNP exposure, develop more suitable experimental models, investigate the health effects of different types of MNPs, explore their mechanisms in greater depth, and comprehensively assess various influencing factors. These efforts will provide essential insights for a more thorough understanding of the impact of MNPs on human health.
