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). To calculate the exposure dose for inorganic arsenic the total arsenic concentration was used along with a conversion factor of 0.2 in the numerator.
Daily doses were calculated using the following formula: Dose = Conc. x IR.
The body metabolizes arsenic into a less harmful form at doses of 0.05 mg/kg/day.
Health effects were reported from exposure to arsenic at doses of 0.014 mg/kg/day.
Cancer effects were reported from exposures to arsenic at doses of 0.01-0.05 mg/kg/day.
No adverse health effects were reported from exposure to lead at doses of 0.57-27 mg/kg/day.
CDC's blood lead level of concern is 10 mg/dl.
No adverse health effects were reported from exposure to mercury at doses of 0.0013 mg/kg/day.
No adverse health effects were reported from exposure to selenium at doses of 0.015 mg/kg/day.
No adverse health effects were reported from exposure to copper at doses of 10 mg/day.
