. USEPA sets standards for arsenic emission from foundry so that the unit cancer risk is 0.015 (per ug/m3 of arsenic in the atmosphere over a lifetime period). Assuming the exposure to arsenic is 25 years, what should be the maximum concentration of arsenic in ambient air in a way that the real risk of getting cancer during these 25 years is 0.0001 (one chance in ten thousand)?
