Scientists today say we’re just beginning to understand the harm that the tiny bits of plastic we drink, eat and breathe are doing to the human body. But recently discovered chemical company documents dating back several decades show that industry scientists have long been aware of — and concerned about — the way microplastic particles migrate beyond the gut in animals and humans, depositing in important organs. … [T]heir presence has become concern enough among health officials, lawmakers and researchers that in 2018, California passed a law requiring the state’s water agency to define, test for, and report the particles in drinking water. The Trump administration, averse to most regulation, announced earlier this year that the EPA would begin tackling them in drinking water as well.
