Comparison of Average Mercury Concentrations Among Crab Sample Types. For comparison purposes, NJDEP routine monitoring data have been summarized and are presented in Table 5-2. In 2004, blue crabs were collected from the Lower Passaic River and Newark Bay Complex by Dr. Richard Horwitz under the statewide “Routine Monitoring Program for Toxics in Fish” as developed by NJDEP’s Division of Science, Research and Technology (DSRT) (NJDEP, 2006d). The objective of the program is to update human health consumption advisories for fish and shellfish of concern and to identify contaminant concentrations in marine and estuarine species along New Jersey’s coast. Muscle meat and hepatopancreas composite tissue samples from five blue crabs collected specifically from the Lower Passaic River were analyzed for total PCBs, total DDx, total mercury, and 2,3,7,8-TCDD. A comparison of the NJDEP data in Table 5-2 with the site data in Figures 5-5 and 5-6 shows that average concentrations of total PCBs and total DDx compounds determined by NJDEP for hepatopancreas and muscle tissue samples were much lower than those associated with the site data. Conversely, NJDEP data for the average total mercury concentrations in hepatopancreas and muscle samples were approximately double those concentrations determined for the site (see Figure 5-7). Hepatopancreas and muscle tissue samples for both NJDEP and the site were consistent for 2,3,7,8-TCDD. 5.1.4.2 Exposure Factors The population of concern in this HHRA consists of the inhabitants of the towns, cities, and rural areas surrounding the 8-mile stretch of the Passaic River who may fish and/or crab in the river or eat catch from this area. The angler population is defined as those individuals who consume self-caught fish from the 8-mile stretch of the Passaic River regardless of the fish/crab consumption advisories. The assessment of fish consumption by the angler population includes young children (ages 0-6), adolescents (ages 10 to 18 years), and adults (over 18). Prenatal and neonatal exposures are evaluated qualitatively.
