Lead is a toxic metal found in the earth’s crust. But it’s over use results in extensive environmental contamination and significant public health problems.
The sources of environmental contamination are mining, smelting, manufacturing and recycling activities, continued use of leaded paint and continued use of leaded gasoline.
The main global lead consumption is the manufacture of lead-acid batteries for motor vehicles, pigments, paints, solder, stained glass, crystal vessels, ammunition, ceramic glazes, jewellery and baby toys.
Many piped water in developing countries are contaminated with lead particles because it passes through solder piped.
Lead causes long-term harm in adults such as high blood pressure, kidney damage miscarriages, stillbirths, premature birth, low birth weight, and minor malformations.
