Summary

A rat study using metabolomics analysis found that long-term exposure to high concentrations of polystyrene microplastics led to abnormal fat metabolism and cardiovascular damage. The harm appeared to be driven by oxidative stress and inflammation, suggesting that chronic microplastic exposure could contribute to heart and blood vessel disease.

These results suggest that long-term exposure to high concentrations of PS-MPs may lead to abnormal lipid metabolism and cardiovascular system damage. The mechanism may be related to oxidative stress and inflammatory response. Exogenous antioxidants and changes in own metabolites may have a protective effect on the injury. Therefore, understanding the toxicological mechanism of PS-MPs not only helps to elucidate its pathogenesis, but also provides new ideas for the treatment of chronic diseases.
