Mc-DERMOTT-EHRLICH ET AL.: CHLORINATED HYDROCARBONS IN DOVER SOLE 



SUMMARY 



1. Levels of DDT in Dover sole with fin erosion 

 collected off Palos Verdes and Orange County 

 were not significantly different. This is con- 

 sistent with the hypothesis that the Orange 

 County diseased fish migrated from the Palos 

 Verdes region and that the disease did not 

 originate at Orange County. 



2. A dominant point source discharge of a con- 

 taminant, such as the municipal wastewater 

 discharge of DDT compounds off Palos Verdes, 

 may provide a useful tag when investigating 

 the migration offish from or across that point 

 source. 



3. Dover sole with fin erosion from Palos Verdes 

 have significantly higher levels of total DDT 

 (P<0.05) than Dover sole without the disease 

 from the same region. 



4. There is a tendency for Dover sole with fin 

 erosion from Palos Verdes to have higher 

 levels of PCB (P<0.10) than Dover sole with- 

 out the disease from the same region.
