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.
