A recent study – conducted by a team of researchers at the University of California – revealed that exposure to microplastic particles negatively affects the functions of the reproductive and respiratory systems, and also increases the risk of certain types of cancer, including colon cancer and lung cancer.
The researchers reported that an analysis of more than 3,000 studies on humans and animals showed that these fine particles contribute to damage to the protective mucous layer in the colon, which enhances the possibility of developing tumors.
The results also showed a link between these particles and disorders in the digestive system, in addition to their role in poor sperm quality and ovarian function.
Microplastics are defined as pieces of plastic less than 5 millimeters in diameter, resulting from the consumption of everyday goods such as food containers, clothing, toys, packaging, cigarette filters, and tires.
These particles have been found in the air, food, and water, and have been detected in human organs.
According to the study, these particles cause widespread inflammation as a result of the immune system recognizing them as foreign substances, which leads to tissue damage and inflammation in the liver and heart. The study showed that its accumulation in the body in the long term may cause permanent damage that is difficult to treat.
For her part, Tracy Woodruff, a professor of obstetrics and gynecology at the University of California, said, “These plastic particles represent dangerous molecular air pollutants. We know that air pollution of this type is extremely harmful.”
She added that global production of plastic reaches 460 million tons annually, and is expected to double to reach 1.1 billion tons by 2050. This study highlights the importance of taking urgent measures to reduce the use of plastic and reduce its negative effects on public health and the environment.
