"Traditional paints emit volatile organic compounds (VOCs), chemicals that
damage the environment and diminish human health. These adverse health
effects include damage to the liver and nervous system, otolaryngological
(ear, nose and throat) complications, headaches and cancer. The National
Cancer Institute reports that professional painters have a higher risk of
developing cancer than non-painters. Constant exposure to paint toxins
causes hazardous effects."
Article recommends nothing but whitewash (slacked lime and water) for all
your painting needs, a la Tom Sawyer and his fence.
(Just kidding on the last)
