I fail to understand the problem. With the finding that LEAD (Pb) was used in the inks that were commonly used in commercial printing prior to 1985, and the fear that children will tear out the pages and ... eat them.
According to the USA Today newspaper "The US Consumer Product Safety Commission, the federal agency in charge of enforcing the law, announced that it won't prosecute anyone for distributing "ordinary" children's books printed after 1985. These books have never been found to violate the new lead standards, which will mandate that kids' items contain no more than 600 parts per million beginning Tuesday. The standards get twice as tough in August when the limit will be 300 parts per million."
So All of the books most of us over 30 read as children are already on the banned list.
