NOAA Tech Memo NMFS NWFSC-8: Contaminant Exposure in Juvenile Salmon (cont): Figure 3

Hepatic polychlorinated biphenyls (PCBs) (ng/g wet liver wt.) in juvenile salmon from estuaries and hatcheries sampled from Puget Sound, Washington, in 1989 and 1990. The bars represent the mean ± standard error. The sample size (n) equals the number of tissue composites that were analyzed. Site designations are as described in Figure 2. The letter (a) indicates values that are significantly different than salmon from the combined hatcheries and the NE, and (b) indicates values that are significantly different than for salmon from the combined hatcheries only. The results (mean ± standard error) for the the individual hatcheris are presented in Appendix Table A-8.
