Is lead exposure going up or down? I assume it's going down, because lead gasoline was banned, lead paint was banned, and the lead that was in the environment due to those 2 source is slowly being cleaned up.
I at least assume lead exposure now is lower than when leaded gas was primarily used. In the US it started to be phased out in 1973 and finished in 1996.
