Lead+2

=Lead (Pb) =  History:    Lead has been used for thousands of years because it is easy to extract, easy to work worth, and widespread. Lead beads were discovered around 6400 B.C. in what used to be a small settlement. Also, the Romans used lead for water pipes and were able to use its molten form as solder. Lead was also used to hold large monuments together with iron pins that were attached to large limestone blocks. By the mid-1980's, there was a significant shift in the amount of lead using products because of health and environmental standards.   What is it used for?  Lead is used in the production of batteries, ammunition, metal products (solder and pipes), and devices to shield X-rays. However, because of lead's effects on human health, lead in paint has been removed, lead solder and pipes have been severely discouraged and hardly found, and in 1996 leaded gasoline was banned in the United States.     lead consisting battery lead pipe bringing bathing and drinking water to Rome    <span style="font-size: 140%; font-family: 'Times New Roman', Times, serif; text-align: left; display: block;"><span style="font-size: 80%; font-family: 'Times New Roman', Times, serif; color: rgb(39, 151, 252);">Why is it considered hazardous? <span style="display: block; font-size: 140%; font-family: 'Times New Roman', Times, serif; color: rgb(9, 1, 1); text-align: left;"><span style="font-size: 14pt; font-family: 'Times New Roman', Times, serif;"><span style="font-size: 80%; font-family: 'Times New Roman', Times, serif; text-align: left; display: block;">The Department of Health and Human Services has determined that lead and lead compounds are “reasonably anticipated” to be human carcinogens.Along with this, lead causes the breakdown of the brain and nervous system, eventually leading to death. <span style="display: block; font-size: 140%; font-family: 'Times New Roman', Times, serif; color: rgb(9, 1, 1); text-align: left;"> <span style="display: block; font-size: 140%; font-family: 'Times New Roman', Times, serif; color: rgb(9, 1, 1); text-align: left;"> <span style="display: block; font-size: 150%; font-family: 'Times New Roman', Times, serif; color: rgb(20, 135, 250); text-align: left;">Where might we be exposed to this substance? <span style="display: block; font-size: 140%; font-family: 'Times New Roman', Times, serif; color: rgb(9, 1, 1); text-align: left;"><span style="font-size: 12pt; font-family: 'Times New Roman', Times, serif;">Lead can be breathed in or swallowed. However, most people are exposed to lead because of old pipes that could have lead solder, which then enters their drinking water. Also, lead based paint used to be legal and many old homes must be carefully watched because this peeling lead paint. The paint can become a dust and the lead compounds inhaled or swallowed. <span style="display: block; font-size: 140%; font-family: 'Times New Roman', Times, serif; color: rgb(9, 1, 1); text-align: left;"> <span style="display: block; font-size: 140%; font-family: 'Times New Roman', Times, serif; color: rgb(9, 1, 1); text-align: left;"> <span style="display: block; font-size: 150%; font-family: 'Times New Roman', Times, serif; color: rgb(24, 133, 251); text-align: left;">Health effects of exposure? <span style="display: block; font-size: 140%; font-family: 'Times New Roman', Times, serif; color: rgb(9, 1, 1); text-align: left;"><span style="font-size: 12pt; font-family: 'Times New Roman', Times, serif; color: rgb(0, 0, 0);">Exposure to Lead leads mainly to long-term health effects in both adults and children alike.

In both adults and children, exposure to large amounts of Lead can severely damage the brain and kidneys, which ultimately lead to death. Also, Lead exposure can cause sterility in men and dramatically increase the chances of a miscarriage in women.
