[quote=Anonymous][quote=Anonymous]Lead poisoning is a huge issue in poor Baltimore areas. [/quote] That can't possibly account for all of it though. Children used to have much higher levels of lead in their blood ("one survey has shown that the mean blood lead concentration in children has dropped from 13.7 mg/l in 1976 to 3.2 mg/l in 1994 [Pirkle et al., 1994, cited by Needleman, 1998b]" from http://rachel.org/files/document/Lead_Poisoning_in_Historical_Perspective.pdf). What we now consider high levels used to be pretty much nothing. Certainly it causes issues, but it's in combination with everything else the children in Baltimore have to deal with that it leads to such dire outcomes.[/quote]
