In an in vitro laboratory study of the extractability of lead in printed matter it was found the dangerous quantities of lead, up to 2001, could be extracted from small pieces of printed paper at Ph values in the range of human gastric lead was not extracted at pH values in the range of human saliva. Children who chew printed manner may not be in danger of absorbing lead, but the pica prone child who swallows printed material may be at risk of absorbing excessive amounts of this toxic metal. The use of printing inks containing high-lead levels should be discouraged.
