Why can't we have safer housing.

This research, from the University of Rochester Medical Center, with more evidence about the deleterious effects of ingested lead, still fails to focus on the most effective way to prevent lead poisoning - safe housing. With leaded gasoline and leaded paint banned, with safer lead smelters the main cause of childhood lead poisoning is of from older homes. The vast majority of these homes are owned by slum landlords. A simple rental occupancy code that prohibits the rental of any dwelling untreated for presence of lead would solve most of the lead poisoning of children. yet we keep waiting until a child's blood lead level is high, then treat them and send them back to the same environment.
