3M, the company that invented Post-It Notes and Scotch Tape, uses human-made compounds called fluorochemicals in many of its products.
ProPublica reported that these chemicals have been found in human blood and are toxic, based on extensive research studies. However, the company reportedly kept this information from the public and continued releasing products with the chemicals into the world.
What’s happening?
A 3M chemist named Kris Hansen first tested human blood for fluorochemical contamination in 1997. At that time, she was not aware that the chemical had been tested on animals in the 1970s and found to be toxic and even deadly, per ProPublica.
When Hansen told her boss about discovering the chemical in general population blood samples, he cryptically said: “This changes everything,” but then packed up and ultimately left for an early retirement in the middle of further testing.
