Microplastic (MP) exposure is linked to cognitive decline. Higher MP concentrations in blood, urine, and feces correlate with reduced cognitive function, highlighting the need to reduce plastic use and improve waste management.
Area of Science:
- Environmental Health
- Toxicology
- Neuroscience
Background:
- Microplastics (MPs) are pervasive environmental pollutants.
- Exposure to MPs can negatively impact human health, affecting cognitive function through toxicity, oxidative stress, and inflammation.
Purpose of the Study:
- To evaluate the relationship between microplastic (MP) exposure patterns, MP concentrations in biological fluids (blood, urine, feces), and cognitive function.
- To investigate the association between MP levels in biological samples and cognitive performance.
Main Methods:
- Two-phase study: online survey (n=562) on plastic consumption and MP awareness, followed by biological sample collection (blood, urine, feces) from high and low exposure groups (n=67).
- Assessed MP concentrations in biological fluids and cognitive function using the Montreal Cognitive Assessment Indonesia (MoCA-Ina).
Main Results:
- Polyethylene terephthalate (PET) and polypropylene (PP) microplastics were detected in blood, urine, and feces.
- A significant association was found between MP exposure levels and MP concentrations in biological fluids.
- Higher MP concentrations were linked to cognitive decline, especially in highly exposed individuals.
Conclusions:
- Microplastic exposure is significantly related to adverse health impacts, particularly cognitive decline.
- Findings emphasize the urgent need to reduce plastic consumption, increase public awareness, and implement effective plastic waste management policies to mitigate health risks.
