Lead paint or lead-based paint is paint containing lead, as pigment, with lead(II) chromate (PbCrO4, "chrome yellow") and lead(II) carbonate (PbCO3, "white lead") being the most common. Lead is added to paint to speed up drying, increase durability, maintain a fresh appearance, and resist moisture that causes corrosion. It is one of the main health and environmental hazards associated with paint. In some countries, lead continues to be added to paint intended for domestic use, whereas countries such as the U.S. and the U.K. have regulations prohibiting this, although lead paint may still be found in older properties painted prior to the introduction of such regulations. Although lead has been banned from household paints in the United States since 1978, paint used in road markings may still contain it. Alternatives such as water-based, lead-free traffic paint are readily available, and many states and federal agencies have changed their purchasing contracts to buy these instead.

Famous quotes containing the words lead and/or paint:
“No one—man or woman—can have it all without support from the workplace and genuine help at home. Women, regardless of how they have chosen to lead their lives, can now breathe a collective sigh of relief that superwoman is dead.”
—Deborah J. Swiss (20th century)
“We can paint unrealistic pictures of the juggler—displaying her now as a problem-free paragon of glamour and now as a modern hag. Or we can see in the juggler a real person who strives to overcome the obstacles that nature and society put in her path and who does so with vigor and determination.”
—Faye J. Crosby (20th century)
