Reply to comment by thedl894 in ELI5: Why does it seem as if most every day use items have carcinogens or other chemicals that can harm or kill you? by thedl894

Sometimes we only find out much later that something we thought was OK is actually harmful. Also a key element is quantity. Something in the ppm range may not cause harm, while the same thing in the percent range could. Plus the FDA doesn't regulate everything.
