How is our understanding about the health effects of lead changing?
Current research shows that lead is harmful to the body at lower levels, levels that were previously thought safe. This is especially true if a person is exposed over a long period of time. Lead exposure has been shown to contribute to health problems such as high blood pressure, nervous system and kidney damage, and problems with pregnancy. Even if a person is not currently being exposed to lead, this health damage can continue as lead that is stored in bones gradually moves back into the bloodstream.
