Organohalogen contaminant (OHC) threats remain largely a mystery for threatened loggerhead sea turtles (Caretta caretta). This study examines regional-scale OHC differences in blood plasma from adult male C.caretta based on movement patterns. Turtles were

Marine animals are faced with health threats including disease and accumulation of toxic pollutants. There are several efforts in the USA seeking to relate health metrics to the exposure of marine animals to pollution, biotoxins, and disease. The National

Biomonitoring of wild cetaceans for persistent organic pollutants (POPs) is heavily reliant on concentrations determined in blubber, and there are few data relating blubber concentrations and levels in blood. Matched blubber and plasma samples (n=56) were

The majority of exposure assessments for free-ranging cetaceans focus on contaminant concentrations measured in blubber, and there are few data for other tissues or the factors governing contaminant distribution between tissues. The goal of this study was

Perfluorinated compounds (PFCs) are globally distributed persistent environmental contaminants. This study provides temporal trends as well as large-scale spatial trends of PFC concentrations in threatened juvenile loggerhead sea turtles from Florida (FL)

Bottlenose dolphins (Tursiops truncatus) are prone to accumulating complex mixtures of persistent organic pollutants (POPs). While variations in POP patterns have been previously observed for populations separated across regional and fine-scale geographic

Toxaphene is a complex technical mixture that has been found ubiquitously in the environment but has caused issues for analysis, especially of individual congeners. This paper reports the elution order of 25 major toxaphene congeners on three gas

The threat that exposure to organohalogen (OH) contaminants poses to endangered populations of Kemp's ridley (Lepidochelys kempii) and green sea turtles (Chelonia mydas) is not well understood, partly because few OH data are available. Blood samples from

An increasing number of studies use blood obtained non-invasively to monitor organohalogen contaminants. However, blood can be a difficult tissue to analyze for organohalogen pollutants due to interferences from co-extracted proteins. We compared five

The National Institute of Standards and Technology (NIST) has developed four Standard Reference Materials (SRMs) related to the monitoring of contaminants in fish and marine mammals: SRM 1588b Organics in Cod Liver Oil, SRM 1945 Organics in Whale Blubber
Polybrominated diphenyl ethers (PBDEs) are widely-used as flame retardants in electronic devices and upholstery. These are mobile in the environment, persistent, and bioaccumulative and are frequently found at low (pg/g) concentrations in many
