Table 1. Summary of Concentrations of Major Organochlorine Contaminant Classes in Blubber of Selected Marine Mammal Species from US Waters as Reported in Literature from 1994-2005
Table 1. Summary Data for Some Persistent Organic Pollutants, Including PCBs, DDTs, Chlordanes, Mirex, Dieldrin, HCHs and HCB in Blubber of Selected
Marine Mammal Species from US Waters, Reported 1994 through 2005.
For each species, the lowest and highest overall means among reported studies are given, followed by the corresponding sample size, as well as overall
ranges for animals in all studies combined.
