Persistent organic pollutants in fat of three species of Pacific pelagic longline caught sea turtles: Accumulation in relation to ingested plastic marine debris.
In addition to eating contaminated prey, sea turtles may be exposed to persistent organic pollutants (POPs) from ingesting plastic debris that has absorbed these chemicals. Given the limited knowledge about POPs in pelagic sea turtles and how plastic ingestion influences POP exposure, our objectives were to: 1) provide baseline contaminant levels of three species of pelagic Pacific sea turtles;...
متن کاملStatus of sea turtle stocks in the Pacific
Six species of sea turtles occur in the Pacific Ocean (green turtles, loggerheads, leatherbacks, hawksbills, olive ridleys and flatbacks). All species, except flatbacks, have transboundary distributions. The status of most sea turtle stocks in the Pacific Ocean is poorly understood. Some stocks are increasing, such as in eastern Australia and Hawaii. However, there is evidence that many stocks ...
متن کاملPathology and distribution of sea turtles landed as bycatch in the Hawaii-based North Pacific pelagic longline fishery.
We examined the gross and microscopic pathology and distribution of sea turtles that were landed as bycatch from the Hawaii, USA-based pelagic longline fishery and known to be forced submerged. Olive ridley turtles (Lepidochelys olivacea) composed the majority of animals examined, and hook-induced perforation of the esophagus was the most common gross lesion followed by perforation of oral stru...
متن کاملLack of xenoestrogen-induced vitellogenin in male olive ridley sea turtles (Lepidochelys olivacea) from the Pacific coast of Costa Rica
Olive ridley sea turtles (Lepidochelys olivacea) distribute widely throughout Eastern Pacific (EP) waters. During reproduction these animals aggregate near coastal waters where they may be exposed to industrial or agrochemical environmental pollutants that may disrupt the endocrine system of these reptiles. One group of compounds of concern is the persistent organic pollutants (POPs), some of w...
