| ddt in endangered galapagos sea lions (zalophus wollebaeki). | we characterize for the first time the presence of ddt and its metabolites in tropical galapagos sea lions (zalophus wolleabeki). ?ddt concentrations in galapagos sea lion pups sampled in 2005 and 2008 ranged from 16 to 3070 µg/kg lipid. concentrations of ?ddt in pups in 2008 averaged 525 µg/kg lipid and were 1.9 times higher than that (281 µg/kg lipid) detected in pups in 2005. these concentrations are lower than those reported in many pinnipeds elsewhere, comparable to those in hawaiian monk s ... | 2011 | 21353257 |
