Summary

Researchers found that low concentrations of microplastics may promote brain cancer cell growth in laboratory experiments, while very high concentrations became toxic to the cells. The study highlights concerns about microplastics crossing the blood-brain barrier and interacting with human cells, though the findings are preliminary lab-based results.

Body Systems

Numerous studies have revealed that microplastic particles in most food and beverages can harm humans.Microplastics are found to penetrate the blood-brain barrier that protects the human brain from harmful substances, causing severe damage and even cancer cell proliferation.This study determined the impact of microplastics on brain cancer cells.In addition, the study was continued in more detail about how the higher concentration of microplastics affects brain cancer cells.However, the microplastic floating above the cancer cells never interacted with each other.As a solution, microwaved microplastic (MMP) was used to make the particles smaller and less dense so that they would not float but interact with the cancer cells.As a result, it was found that 2% MMP may support brain cancer cell proliferation, but 20% MMP may induce cytotoxicity in brain cancer cells.Overall, these findings indicate that small amounts of microplastics can promote cancer cell growth, highlighting the need for people to be aware of the presence of microplastics in their daily lives.
