Plastic pollution is contaminating our environment at an alarming rate. Recent studies suggest a potential link between microplastics in our bodies and certain diseases.
the rise of plastic consumption and its impact
In the 1950s, global plastic consumption was about 1.5 million tons annually. Today, this figure exceeds 400 million tons, with projections indicating it could reach 12 billion tons in landfills by 2050. This surge stems from our society’s preference for disposable products.
The growing plastic pollution problem was highlighted during a recent international summit in Busan, South Korea, where representatives from 170 countries attempted to finalize a treaty against plastic pollution without reaching an agreement. Negotiations are expected to resume in 2025.
microplastics: where they are found in the body
While policymakers debate, scientists continue to investigate the effects of plastic pollution on ecosystems and human health. Microplastics have been discovered in various environments: water, soil, air, and even within the human body—lungs, blood, digestive system, and more.
Did you know?
Microplastics are defined as plastic particles smaller than 5 millimeters. Nanoplastics measure under 1 micrometer or 100 nanometers.
A comprehensive review by researchers from Zhejiang Agriculture and Forestry University examined numerous scientific publications highlighting microplastic presence in human tissues using techniques like spectroscopy and chromatography-mass spectrometry.
- Microplastics have been detected in skin, arteries, veins, bone marrow, reproductive organs like testes and uterus, saliva to excrement within the digestive tract.
- Respiratory systems showed microplastic fibers present even in bronchoalveolar lavage fluid.
correlation between microplastics and tissue damage
Toxicological studies suggest a correlation between high levels of microplastics and inflammatory bowel diseases or cervical cancer. Researchers observed higher concentrations of microplastics in damaged tissues such as inflamed intestines or fibrotic lungs compared to healthy tissues.
- This raises questions about whether microplastic accumulation contributes to tissue damage or if already-damaged tissues attract more particles.
potential health risks of microplastic exposure
A second review conducted by the University of California involved over 1,000 studies on MNP exposure effects on human health. While evidence varies in strength across different health aspects—strong for sperm quality but weak regarding pregnancy impacts—the pervasive presence of MNPs suggests potential harm to various bodily systems.
- This underscores urgent needs for further research and proactive political measures addressing both production control strategies along with reducing human exposure risks through policy changes globally.
