Summary

Researchers reviewed evidence on microplastic contamination and its potential effects on kidney health, noting that microplastics have been detected in kidneys and urine in humans. In vitro and animal studies suggest potential nephrotoxicity from microplastic exposure, and patients with kidney diseases may face increased risk due to higher exposure through medical procedures and reduced urinary elimination. The study calls for further research to clarify the relationship between microplastic exposure and kidney damage.

Models
Study Type In vitro

The production of plastics is steadily increasing and raises major environmental and public health concerns. Those used every day, including in the medical sector, lead to the formation of microplastics (MP). These can then contaminate water, air, soil and our food. Through inhalation or ingestion, MP can enter the bloodstream and reach various organs. The presence of MP has also been demonstrated in the kidneys and urine. In vitro and animal studies suggest potential nephrotoxicity of MP. Patients with kidney diseases may be at increased risk due to higher exposure through medical procedures and reduced urinary elimination. Further studies are needed to clarify this risk.
