distribution of total mercury and methyl mercury in water, sediment, and fish from south florida estuaries.	concentrations of total mercury and methyl mercury were determined in sediment and fish collected from estuarine waters of florida to understand their distribution and partitioning. total mercury concentrations in sediments ranged from 1 to 219 ng/g dry wt. methyl mercury accounted for, on average, 0.77% of total mercury in sediment. methyl mercury concentrations were not correlated with total mercury or organic carbon content in sediments. the concentrations of total mercury in fish muscle were ...	1998	9469852

polybrominated diphenyl ethers and polychlorinated biphenyls in a marine foodweb of coastal florida.	nine species of marine fish, including teleost fishes, sharks, and stingrays, and two species of marine mammals (dolphins) collected from florida coastal waters were analyzed for polybrominated diphenyl ethers (pbdes) and polychlorinated biphenyls (pcbs) to evaluate biomagnification factors (bmf) of these contaminants in a coastal foodweb. in addition, bottlenose dolphins and bull sharks collected from the florida coast during the 1990s and the 2000s were analyzed for evaluation of temporal tren ...	2005	16294860
residues of organochlorine insecticides, polychlorinated biphenyls, and heavy metals in biota from apalachicola river, florida, 1978.	seventy-seven composite samples composed of largemouth bass ( micropterus salmoides ), channel catfish ( ictaluras punctatus), threadfin shad ( dorosoma petenense ), asiatic clam (corbicula fluminea ), burrowing mayfly ( hexagenia sp.), water snake ( natrix spp.), and little green heron ( butorides virescens ) were collected from upper and lower reaches of the apalachicola river, florida, in 1978 for residue analysis of organochlorine insecticides, pcbs (polychlorinated biphenyls), and metals. c ...	2013	6427177
comparison of edwardsiella ictaluri isolates from different hosts and geographic origins.	the intraspecific variability of e. ictaluri isolates from different origins was investigated. isolates were recovered from farm-raised catfish (ictalurus punctatus) in mississippi, usa, tilapia (oreochromis niloticus) cultured in the western hemisphere and zebrafish (danio rerio) propagated in florida, usa. these isolates were phenotypically homologous and antimicrobial profiles were largely similar. genetically, isolates possessed differences that could be exploited by repetitive-sequence-medi ...	2016	26661707
