You probably wouldn’t expect to find pesticides in your toothpaste or your gym socks, but they might be in there all the same. And the vast majority of those pesticides have made it into everyday products without adequate oversight by the Environmental Protection Agency. That’s because they’ve been approved through a bureaucratic loophole known as “conditional registration,” which means they haven’t been fully tested to ensure that they pose no threat to human health or the environment, as required by U.S. law.
Most of us think of pesticides as the chemicals that get sprayed on weeds or used to kill rodents and bugs, but they’re actually found in everything from cosmetics to food containers, as well as antimicrobial textiles (such as the exercise shirt you might have worn to the gym this morning). By killing bacteria and other microorganisms, pesticides can help clothes resist stains or help containers keep food fresh longer. But some have also proven to cause health concerns in humans,kill trees, birds, bees, and fish, or do other unintended harm to the environment.
