Summary

This review examines how micro- and nanoplastics can damage mitochondria, the energy-producing structures inside cells that are critical for metabolism and cell survival. Researchers found that plastic particle exposure can trigger oxidative stress, disrupt mitochondrial membrane function, and interfere with energy production pathways. Since mitochondrial dysfunction is linked to numerous health conditions, the study suggests this may be a key mechanism through which plastic pollution affects human health.

Body Systems

Mitochondria are highly dynamic cellular organelles that perform crucial functions such as respiration, energy production, metabolism, and cell fate decisions. Mitochondrial damage and dysfunction critically lead to the pathogenesis of various diseases including cancer, diabetes, and neurodegenerative and cardiovascular disorders. Mitochondrial damage in response to environmental contaminant exposure and its association with the pathogenesis of diseases has also been reported. Recently, persistent pollutants, such as micro- and nanoplastics, have become growing global environmental threats with potential health risks. In this review, we discuss the impact of micro- and nanoplastics on mitochondria and review current knowledge in this field.
