Dragboat is correct. It wss lead-based paints that caused the hullabaloo! Since lead tastes sweet, some children would eat the stuff right off the walls. Parental control and responsibilty maybe?
Ethyl is a great additive company. No one forsaw that lead would become a residue in soil and water. More environmental testing is done now than in the past. Some EPA rhetoric is scientific based, but most is political, aka, the Kyoto Protocol!
