Supporting Information Tables. Table S1, Levels of selected heavy metals and other trace elements detected in Baltimore soils.

Reported levels may be capped at minimum and maximum detectable levels. Table S2, Examples of potential urban soil contaminants, recognized sources, and health effects associated with exposure. Table S3, Examples of contaminant concerns expressed by key informants.
