Notes: Averages were calculated using detected values only.
Daily doses were calculated using the following formula: Dose = Conc. x IR.
Childhood poisoning was reported from exposure to 200 mg/event.

Exposure doses were calculated using 365 days/year for EF in the formula described in the Deriving exposure doses section of this appendix: (Conc. x IR x EF x ED) / (BW x AT).
No adverse health effects were reported from exposure to 0.57-27 mg/kg/day.
Cancer health effects were reported from exposure to 27 to 371 mg/kg/day.

Notes: Averages were calculated using detected values only.
Blood lead levels were calculated by multiplying the concentration by a media-specific slope factor (0.24 mg/dl per ppm) as described in the Using other methods to evaluate potential health hazards section of this appendix.
CDC's blood lead level of concern is 10 mg/dl.
