Lead
has been used for centuries and identified as a poison for
almost as long. Modern artist pigments, solder, casting lead,
ceramic glazes, glass paints, welding auto body parts or grinding
older painted wood may all expose artists. Lead calls for
stringent precautions - or plain avoidance.
Poisoning
from lead white pigment is blamed for the "painter's
colic" common to professional artists in times past.
Lead is absorbed like calcium and spread throughout the body.
Lead poisoning can result in anemia and severely damage the
kidneys, central nervous system, and male and female reproductive
systems. Relatively small exposures can lead to nerve damage,
coma, and death. Irreversible developmental harm from chronic
lead poisoning compelled the bans on leaded gasoline and house
paint.
Work-related
exposure to lead is strictly regulated by the U.S. Occupational
Safety and Health Administration (OSHA).
California's Prop
65 listed lead as a reproductive toxin in 1987 and as
a carcinogen in 1992.

(Note:
The so-called "lead" in pencils is really graphite,
a safe form of carbon.)
