Mercury Mascara: Did you know there's mercury in mascara? We didn't either, until now. The Associated Press reports that mercury is added to some eye products as a preservative and germ-killer. Federal law allows eye products to contain up to 65 parts per million of mercury, but mercury can retard brain development in children and fetuses, who are most vulnerable to the metal's toxic effects, and can also cause neurological symptoms in adults. Since we all wear mascara in the office, we're particularly concerned—stay tuned for further updates.

Healthy tissue then grows on and around the material to create a permanent blockage.
