Risk refers to the probability of injury, disease, or death resulting from exposure to the chemicals identified in this study. Risk values are generally expressed in scientific notation. An individual lifetime risk of one in -4 10,000 is represented as 1 x 10 or 1E-04 (Versar, 1987). Excess cancer risks refer to the increased, probability of cancer above a "normal" rate. Impacts of noncarcinogenic chemicals on human health are evaluated by comparing projected or estimated intakes and reference levels for the chemicals of concern. A reference level represents an acceptable exposure level at which there will be no observable adverse effect or the lowest observable adverse effect on human health. The impact of carcinogenic chemicals is assessed by comparing calculated risks and target risks for known or suspected carcinogens. Target risks for carcinogens generally range from 1E-04 to 1E-07. The estimated subchronic and chronic (short- and long-term, respectively) human intake levels for each of the indicator chemicals is presented in Tables 5-1 and 5-2. Subchronic intake levels, representing short-term intake levels were computed for oral and inhalation routes. Supporting calculations used to determine SDIs and CDIs are found in Chapter 3 and Appendix 3 of this report. The highest oral subchronic daily intake was computed for barium at 2.22E-03 mg/kg/day. Subchronic oral intake levels for the volatile organics ranged from 4.68E-07 to 1.03E-06 mg/kg/day. Subchronic daily intakes from inhalation of volatile organics ranged from 1.57E-08 mg/kg/day for chlorobenzene to 9.59E-08 mg/kg/day for TCE.
