Toothpaste can be widely contaminated with lead and other dangerous heavy metals, new research shows.
Most of 51 brands of toothpaste tested for lead contained the dangerous heavy metal, including those for children or those marketed as green. The testing, conducted by Lead Safe Mama, also found concerning levels of highly toxic arsenic, mercury and cadmium in many brands.
About 90% of toothpastes contained lead, 65% contained arsenic, just under half contained mercury, and one-third had cadmium. Many brands contain a number of the toxins.
The highest levels detected violated the state of Washington’s limits, but not federal limits. The thresholds have been roundly criticized by public health advocates for not being protective – no level of exposure to lead is safe, the federal government has found.
