1- B- Compound has been found in the lab or trip blank.
L- Estimated value is below the calibration range.
J - Estimated value.
2- Source:US. EPA Region 3 Risk Based Concentration Values. These screening values are based on 30 years of exposure 250 days per year. Actual exposure is greatly reduced due to restricted access.
3- Values inferred from PAH toxicity equivalency factors (ATSDR 1995).
4- See text for evaluation.
