25 Mar 2022 --- Microplastics have been detected in human blood cells for the first time, sparking fears that continued packaging pollution could result in rising disease rates. A team of scientists in the Netherlands sought to quantify levels and types of plastic in 22 human subjects’ blood and discovered particles in 80% of them. The researchers say the findings are a “breakthrough” discovery and “certainly a reason to be concerned.” The study adds to a body of evidence that microplastics are contaminating human and environmental health, with particles found on Mount Everest, in deep ocean waters and human fetuses.
