Researchers Raise Alarm about Ingested Nanoscale Microplastic Particles Not Previously Evaluated

(Beyond Pesticides, January 18, 2024) Research continues to raise alarms about the hazards associated with the use of plastic, including the microplastic particles that are distributed in alarming amounts throughout the environment and taken up by organisms, including humans. A study published by researchers at Columbia and Rutgers universities (see article in the Proceedings of the National Academy of Sciences, January 2024) reports that the average liter of three brands of bottled water in the U.S. contains almost a quarter of a million tiny plastic pieces, of which 90 percent are at the nanoscale. The other ten percent are slightly larger, at microscale. Last December, researchers at Norway’s MicroLEACH project published a study that analyzes the components of 50 items in common use—plastic bags, disposable cups, dishwashing gloves, car tire granules, children’s toys and balloons. (See summary.) The researchers found, like in previous studies, that many hazardous chemicals in the plastics as well as many that could not be identified because they were not listed in the major chemical substance databases. Only 30 percent of the chemical compounds identified in the study were present in two or more products. This suggests that most plastics contain many unidentified chemicals, far beyond […]
