Study links microplastics to lung and colon cancer risks, expert warns of health crisis

A new review led by a Sydney expert links microplastics to lung and colon cancer. The study analyzed 3,000 research papers, finding that microplastics may also harm sperm quality and increase gut inflammation and lung injury. Microplastics, tiny plastic fragments less than 5 millimeters long, can enter the bloodstream through consumption and inhalation. They have been detected in various human tissues, but most studies on health effects have been conducted on animals. The lead researcher, Dr. Nicholas Chartres, urges immediate action to reduce plastic use, citing potential health risks. However, some experts caution that more research is needed to fully understand the impact of microplastics on human health.
