**: Carcinogenic PAHs.

#: Levels represent the conservative level of protection for the sum of the related compounds and their metabolites.

na: Not Available

1. An “*” in this column indicates that the analyte concentration in the test sediment-exposed organisms are statistically greater than in those exposed to reference sediment. Means and statistical comparisons were determined using ½ the detection limit to estimate concentrations of analytes that were below the detection limit.

2. Conversion factors from 28-day bioaccumulation results to steady state (see discussion in Appendix).

3. Toxic equivalencies (TEFs) for the carcinogenic PAHs are from EPA (1993); Dioxin TEFs are from: EPA (1989).

4. This value represents the 10-4 cancer risk level for the carcinogenic PAHs. The total concentration of carcinogenic PAHs is expressed in BaP equivalents (see discussion in the text of the memo).

5. Cancer risk factor or reference dose are not assigned by EPA in IRIS (EPA 1995).

6. FDA limits are from EPA/USACE (1991).

7. This value represents the benthic level expected to result in a no-effect level for possible mutagenic and teratogenic effects in fish from exposure to BaP, which is the most toxic PAH.

8. This value represents the non-specific narcosis effects level (see discussion in Appendix). This value is compared to the sum of all PAHs measured.

9. Calculations are included in Appendix.

10. Means of five tissue replicates calculated using 1/2 detection limits to estimate concentrations of analytes that were not detected; “U” indicates that all five replicates were not detected.

11. Levels are based on the Regional Dioxin Values (EPA 1997a).

12. Level is the sum of TEQs of all dioxin congeners other than 2,3,7,8-TCDD.

13. For this PAH, the no-effect level for possible mutagenic and teratogenic effects in fish is estimated from exposure to BaP, which is the most toxic PAH.

14. Cancer and non-cancer protection levels, based on inorganic arsenic as contained in EPA’s IRIS database, are not appropriate for evaluating the potential human health impacts of arsenic bioaccumulation from dredged material, and therefore, are not included in Table 4 (see discussion in Appendix).
