Dear colleagues,

I hope everybody is doing well. Two new contributions on DDT in Galapagos sea lions were recently published. Please, see below
  
DDT in endangered Galapagos sea lions (Zalophus wollebaeki)
Marine Pollution Bulletin, Volume 62, Issue 4, April 2011, Pages 660-671
 
ABSTRACT
We characterize for the first time the presence of DDT and its metabolites in tropical Galapagos sea lions
(
from 16 to 3070 lg/kg lipid. Concentrations of ∑DDT in pups in 2008 averaged 525 lg/kg lipid and were
1.9 times higher than that (281 lg/kg lipid) detected in pups in 2005. These concentrations are lowerp,p'-DDE toxic effect concentration associated with anti-androgenic effects reported in
than those reported in many pinnipeds elsewhere, comparable to those in Hawaiian monk seals, and
higher than those in southern elephant seals. The health risk characterization showed that 1% of the male
pups exceeded the 
rats. The findings provide preliminary guidance on the relationship between DDT use and ecological
impacts, serving as a reference point against which possible future impact of tropical DDT use can be
assessed.
