| geographic specificity of aroclor 1268 in bottlenose dolphins (tursiops truncatus) frequenting the turtle/brunswick river estuary, georgia (usa). | coastal marine resources are at risk from anthropogenic contaminants, including legacy persistent organic pollutants (pops) with half-lives of decades or more. to determine if polychlorinated biphenyl (pcb) signatures can be used to distinguish among local populations of inshore bottlenose dolphins (tursiops truncatus) along the southeastern u.s. coast, blubber from free-ranging and stranded animals were collected along the georgia coast in 2004 and analyzed for pcb congeners using gas chromatog ... | 2008 | 18272207 |
| polychlorinated biphenyls and toxaphene in preferred prey fish of coastal southeastern u.s. bottlenose dolphins (tursiops truncatus). | legacy organochlorine (oc) contaminants continue to pose a potential risk to ecological and human health in coastal aquatic ecosystems of the southeastern united states. polychlorinated biphenyls (pcbs) and toxaphene (tox) were analyzed by gas chromatography with electron capture detection and negative chemical ionization mass spectrometry in 77 composites of four inshore fish species commonly preyed upon by bottlenose dolphins (tursiops truncatus) from estuaries near savannah, georgia (sav), br ... | 2005 | 16445095 |
| growth and reproductive effects from dietary exposure to aroclor 1268 in mink (neovison vison), a surrogate model for marine mammals. | polychlorinated biphenyls (pcbs) from the commercial mixture aroclor 1268 were historically released into the turtle-brunswick river estuary (southeastern georgia, usa) from industrial operations. sum pcbs (σpcbs) in blubber samples from turtle-brunswick river estuary bottlenose dolphins (tursiops truncatus) have been reported at concentrations more than 10-fold higher than those observed in dolphins from adjacent regional estuaries. given that toxicity data specific to aroclor 1268 and applicab ... | 2016 | 26313468 |
| persistent organochlorine pollutants and toxaphene congener profiles in bottlenose dolphins (tursiops truncatus) frequenting the turtle/brunswick river estuary (tbre) in coastal georgia, usa. | although the turtle/brunswick river estuary (tbre) in coastal georgia (usa) is severely contaminated by persistent organochlorine pollutants (pops), little information regarding pops in higher-trophic-level biota in this system is available. in the present study, polychlorinated biphenyls (pcbs), organochlorine pesticides (ocps; including ddts, chlordanes, and mirex), and chlorinated monoterpenes (toxaphene) were measured using gas chromatography with electron-capture detection and gas chromatog ... | 2009 | 19203137 |
| anaemia, hypothyroidism and immune suppression associated with polychlorinated biphenyl exposure in bottlenose dolphins (tursiops truncatus). | polychlorinated biphenyls (pcbs), persistent chemicals widely used for industrial purposes, have been banned in most parts of the world for decades. owing to their bioaccumulative nature, pcbs are still found in high concentrations in marine mammals, particularly those that occupy upper trophic positions. while pcb-related health effects have been well-documented in some mammals, studies among dolphins and whales are limited. we conducted health evaluations of bottlenose dolphins (tursiops trunc ... | 2012 | 21613298 |
| relationship between persistent organic pollutants (pops) and ranging patterns in common bottlenose dolphins (tursiops truncatus) from coastal georgia, usa. | bottlenose dolphins (tursiops truncatus) are apex predators in coastal southeastern u.s. waters; as such they are indicators of persistent organic pollutants (pops) in coastal ecosystems. pop concentrations measured in a dolphin's blubber are influenced by a number of factors, including the animal's sex and ranging pattern in relation to pop point sources. this study examined pop concentrations measured in bottlenose dolphin blubber samples (n=102) from the georgia, usa coast in relation to indi ... | 2011 | 21356543 |
| social differentiation in common bottlenose dolphins (tursiops truncatus) that engage in human-related foraging behaviors. | both natural and human-related foraging strategies by the common bottlenose dolphin (tursiops truncatus) have resulted in social segregation in several areas of the world. bottlenose dolphins near savannah, georgia beg at an unprecedented rate and also forage behind commercial shrimp trawlers, providing an opportunity to study the social ramifications of two human-related foraging behaviors within the same group of animals. dolphins were photo-identified via surveys conducted throughout estuarin ... | 2017 | 28146563 |
