Mercury Contaminent

Every time we did do a lab in a science class with a thermometer the teachers always say to make sure not to break it because of it's harmful affect. It suprises me that its in our air and food and that alot of us have it in our bodys. Fish are the most common way we get it into our systems by which it was first toxic to them. Also it affects your whole body more or less depinding on how much you injest. It affects younger children more than older people but we should keep watching out for how much it contains. It even kills animals that are exposed to enough. At least someone is trying to reduce the amount of mercury in our food, water and air.
