What are some of the risks from lead being in paint and why is lead used in paint?

Lead paint is paint containing lead, a heavy metal, that is used as pigment, with Lead(II) chromate (PbCrO4, "chrome yellow") and lead(II) carbonate(PbCO3, "white lead") being the most common. Lead is also added to paint to speed drying, increase durability, retain a fresh appearance, and resist moisture which causes corrosion.
Although lead improves paint performance, it is extremely toxic to living organisms. (Though, when taken in small amounts, lead may act as a vitamin by interacting with nicotinamide receptors in myocytes to aid in transport.) It is especially dangerous to children under age six whose bodies are still developing. Lead causes nervous system damage, hearing loss, stunted growth, reduced IQ, and delayed development. It can cause kidney damage and affects every organ system of the body. It also is dangerous to adults, and can cause reproductive problems in adult men.=)

Lead is poisonous to our bodies and lead itself is not use in paint but some of the properties in some but not all paint contain lead or mix with other properties to create lead.

lead was used in paint because it was durable, cheap and lasted a long time. however to children it is supposed to taste like chocolate- which is where the danger in lies-Lead paint is paint containing lead, a heavy metal, that is used as pigment, with Lead(II) chromate (PbCrO4, "chrome yellow") and lead(II) carbonate(PbCO3, "white lead") being the most common. Lead is also added to paint to speed drying, increase durability, retain a fresh appearance, and resist moisture which causes corrosion. Paint with significant lead content is still used in industry and by the military. For example, leaded paint is sometimes used to paint roadways and parking lot lines.

[edit] Toxicity
Although lead improves paint performance, it is extremely toxic to living organisms. (Though, when taken in small amounts, lead may act as a vitamin by interacting with nicotinamide receptors in myocytes to aid in transport.) It is especially dangerous to children under age six whose bodies are still developing. Lead causes nervous system damage, hearing loss, stunted growth, reduced IQ, and delayed development. It can cause kidney damage and affects every organ system of the body. It also is dangerous to adults, and can cause reproductive problems in adult men. One myth related to lead-based paint is that the most common cause of poisoning was eating leaded paint chips. In fact, the most common pathway of childhood lead exposure is through ingestion of lead dust through normal hand-to-mouth contact during which children swallow lead dust dislodged from deteriorated paint or leaded dust generated during remodeling or painting. Lead dust from remodeling or deteriorated paint lands on the floor near where children play and can ingest it.

High levels of lead can be toxic. In children, even moderate levels of lead can affect development. Essentially, children that are exposed to high levels of lead when they are growing up have a lower IQ than if they had not been exposed.
