• Toxicity to amphipod survival in samples from the lower Passaic River, Newark Bay and vicinity 

 was highly correlated with the concentrations of PCBs, dioxins, and pesticides, the concentrations of 

 which often exceeded effects-based guidelines or toxicity thresholds. In this area, toxicity was not 

 correlated with the concentrations of PAHs. 



• Toxicity to amphipod survival was not highly correlated with the concentrations of ammonia in the 

 samples. 



• Toxicity to amphipod survival was not significantly correlated with total SEM:AVS ratios. 



• Toxicity to amphipod survival and microbial bioluminescence were moderately correlated with 

 some trace metals, such as lead and zinc. 



• Generally, the correlations between the results of the bivalve embryo tests and the concentrations 

 of all chemicals were poor.

During Phase 1, the following personnel performed the chemical analyses of the sediment samples: 

 Daniel Bardon, George Desreuisseau, Bernadette Koczwara, Robert Lizotte, Richard Restucci, and 

 Julie Seavey (Battelle Ocean Sciences). During Phase 2, the following personnel participated in the 

 sample collections: Douglas Pabst (Chief Survey Scientist), Matthew Masters, Helen Grebe, and Rob- 

 ert Rosenner (U.S. EPA); and Captain Harry Rydquist and Thomas Wyche (U. S. Army Corps of Engi- 

 neers, New York District). During Phase 2, the following personnel participated in the chemical analy- 

 ses of the samples: Donald Tillitt, Bill Brumbaugh, Kathy Echols, Robert Gale, John Meadows, Diane 

 Nicks, and Paul Peterman (National Biological Service, Midwest Science Center). Donald Tillitt per- 

 formed the H4IIE rat hepatoma bioassays. Peter Landrum (NOAA Great Lakes Environmental Re- 

 search Laboratory) conducted toxicity tests with Diporeia spp. Edmundo Casillas (NMFS) provided 

 data from tests of growth impairment and microbial bioluminescence. Kevin McMahon and Pam 

 Rubin (NOAA) edited and Sophie Bowen provided correction assistance. Andrew Robertson and Jay 

 Field (U.S. NOAA/NOS) and Joel O'Connor and Darvene Adams (U.S. EPA, Region 2) provided 

 technical reviews and helpful comments on an initial draft of this report. Jo Linse and Heather Boswell 

 prepared some of the data figures for the report.
