Modeling PAH Toxicity in Sediments Sample Clauses

Modeling PAH Toxicity in Sediments. The concentrations of selected PAHs in the sediments of Port Xxxxxx have been identified in samples collected during several monitoring and research studies. Sampling sites included the Small Boat Harbor (U.S. ACE, 1995), offshore of the Valdez Marine Terminal and Gold Creek (Xxxxx and Shaw, 1993, 1994b, 1995, and 1996; Kinnetics Laboratories Inc., 1995), near Solomon Gulch Hatchery (unpublished data., Xxxxx Xxxx, University of Alaska Fairbanks, 1996), and other deep water areas of the Port (Xxxxx and Shaw, 1993, 1994b, 1995, and 1996). These measured concentrations provided input for the ∑PAH model developed by Xxxxxx et al. (1995). The steps of the model are shown in Figure 2-4. Figure 2-4. Detail of the method used to predict the risk of PAHs in sediments to amphipods. This model combines five well-known models to assess the risk due to hydrocarbons in the sediments.
