The recommended time-weighted average air concentration for occupational exposure to water-soluble hexavalent chromium (Cr VI) is 0.05 mg/m3. This concentration is based on an assumption that the individual is generally healthy and is exposed for 8 hours per day over a working lifetime (that is from age 18 to 65 years). Assuming a body weight of 70 kg and an inhalation rate of 20 m3/h over the working life of the individual, what is the lifetime (70 y) CDI?
