Insights into the development of hepatocellular fibrillar inclusions in European flounder (Platichthys flesus) from UK estuaries.

Hepatocellular fibrillar inclusions (HFI) are an unusual pathology of unknown aetiology affecting European flounder (Platichthys flesus), particularly from estuaries historically impacted by pollution. This study demonstrated that the HFI prevalence range was 6-77% at several UK estuaries, with Spearman rank correlation analysis showing a correlation between HFI prevalence and sediment concentrations of ∑PBDEs and ∑HBCDs. The data showed that males exhibit higher HFI prevalence than females, with severity being more pronounced in estuaries exhibiting higher prevalence.

Organochlorine pesticides and chlorobiphenyls in the blubber of bycaught female common dolphins from England and Wales from 1992-2006.

We report concentrations of organochlorine pesticides (HCB, HCHs, DDTs, dieldrin) and PCBs in the blubber of 43 common dolphins bycaught in fisheries operating off the SW coast of the UK from 1992 to 2006. Concentrations of ΣDDT (summed p,p'-DDT and its metabolites, p,p'-DDE and p,p'-TDE) and of 25 summed CB congeners ranged from 0.2 to 16.
