. Prevalences (%) of hepatocellular specific degeneration/necrosis 
(SDN) in English sole from selected sites in Puget Sound. Sole 
were collected and examined histologically between 1979 and 
1985). The number of fish examined at each site is indicated as 
(n). 
Figure 12. Summary of logistic regression analysis relating sediment concen¬ 
trations of xenobiotics to prevalences of liver neoplasms among 
English sole. Results are expressed as percent of variation 
in neoplasm prevalence. Analysis was based on data from 6 field 
surveys conducted between 1979 and the present, in which 2697 
sole from 46 locations in Puget Sound were examined and 123 
cases of hepatic neoplasms were diagnosed. The overall model 
(AHs + PCBs + size - CBDs - [AH + PCB interaction] ) accounts for 
40.4% of the observed variation in neoplasm prevalene (n.s. = 
effect not significant, p£0.05;* = effect significant, p£0.01;** 
= effect significant, p<0.001;*** = effect significant p£0.0001; 
**** = effect significant, p<0.00001. 
Figure 13. The reproductive success of gravid English sole from Puget Sound 
with or without detectable serious liver lesions. The results 
are based on 65 crosses involving 33 females with serious liver 
lesions, and 158 crosses involving 79 females with no liver 
lesions.
