What are 4 effects of lead poisoning?
Exposure to high levels of lead may cause anemia, weakness, and kidney and brain damage. Very high lead exposure can cause death. Lead can cross the placental barrier, which means pregnant women who are exposed to lead also expose their unborn child. Lead can damage a developing baby’s nervous system.
What are the health effects of lead poisoning in children?
Exposure to lead can seriously harm a child’s health, including damage to the brain and nervous system, slowed growth and development, learning and behavior problems, and hearing and speech problems. No safe blood lead level in children has been identified.

How do you clean up lead?
You can use a special vacuum cleaner called a High Efficiency Particulate Air Filter (HEPA) vacuum to clean up lead. The HEPA vacuum has a special filter that can pick up and hold small pieces of lead. Another option is to use a wet/dry vacuum in the wet setting to clean up the wash or rinse water.
Where is lead found naturally?
Lead can be found in all parts of our environment – the air, the soil, the water, and even inside our homes. Much of our exposure comes from human activities including the use of fossil fuels including past use of leaded gasoline, some types of industrial facilities and past use of lead-based paint in homes.

How is lead created?
Natural formation of lead occurs by radioactive decay of uranium and thorium through radon (222Rn). Four stable isotopes are known, 204Pb, 206Pb, 207Pb and 208Pb, the first three of which are used for estimating the ages of rocks. Lead compounds exist mainly in +2 or +4 oxidation states, the former being more common.
What Colour is lead?
It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is silvery with a hint of blue; it tarnishes to a dull gray color when exposed to air.
Why is lead so heavy?
Lead is a stable metal that’s often used as weights and sinkers. The reason it’s heavy in terms of mass per unit volume (or think about it as per teaspoon), is because the lead atoms are very close, making it a dense material.
