<P> Lead paint or lead - based paint is paint containing lead . As pigment , lead ( II ) chromate ( Pb Cr O , `` chrome yellow '' ) , Lead ( II , IV ) oxide , ( Pb O , `` red lead '' ) , and lead ( II ) carbonate ( Pb C O , `` white lead '' ) are the most common forms . Lead is added to paint to accelerate 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 UK 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 . </P>
