Study of Common U.S. Beverages Find Levels of Toxic Metals That Exceed Standards
A study led by Tulane University recently found that some commonly consumed beverages contain levels of toxic metals that exceed federal drinking water standards. The study was conducted to fill knowledge gaps, as there are few peer-reviewed studies examining the contents of U.S. beverages.
A total of 60 beverages were tested in the study, five of which contained levels of a toxic metal above federal drinking water standards. Additionally, two mixed juices had levels of arsenic above the 10 microgram per liter (μg/L) standard. A cranberry juice, a mixed carrot and fruit juice and an oat milk each had levels of cadmium exceeding the 3 parts per billion (ppb) standard.
