polybrominated diphenyl ethers (pbdes) in great lakes fish: levels, patterns, trends and implications for human exposure. | levels of polybrominated diphenyl ethers (pbdes) were measured in edible portions of great lakes fish, with the goal of examining patterns/trends and evaluating implications for human exposure. a total of 470 fillets of 18 fish species collected from various parts of the canadian waters of the great lakes between 2006 and 2013 were analyzed for 17 (expanded to 33 in 2009) pbdes. for a limited number of species, fillet to whole body and fillet to eggs pbdes were compared to examine pattern and co ... | 2017 | 27865120 |
polybrominated diphenyl ethers and their methoxylated and hydroxylated analogs in brown bullhead (ameiurus nebulosus) plasma from lake ontario. | polybrominated diphenyl ethers (pbdes), methoxylated pbdes (meo-pbdes) and hydroxylated pbdes (oh-pbdes) were detected and quantified in brown bullhead (ameiurus nebulosus) from lake ontario. samples were collected in 2006 from three different locations near the city of toronto: frenchman's bay, toronto island, and tommy thompson park. a total of 117 plasma samples were pooled into 19 samples, separating males and females by site of capture. pooled samples were analyzed for 36 pbdes, 20 meo-pbde ... | 2013 | 23121987 |
polychlorinated biphenyls and their hydroxylated metabolites in wild fish from wheatley harbour area of concern, ontario, canada. | whole-body polychlorinated biphenyls (σpcbs) and plasma hydroxylated pcbs (oh-pcbs) concentrations were determined in brown bullhead (ameiurus nebulosus) from wheatley harbour, ontario, canada. elevated σpcbs in wheatley harbour are suspected to have originated from industrial waste disposal and/or discharges from nearby fish processing through discarding of fish remains. mean σpcb concentrations in brown bullhead from wheatley harbour were approximately 250 ng/g wet weight compared with approxi ... | 2012 | 23027467 |
assessment of the health status of wild fish from the wheatley harbour area of concern, ontario, canada. | the overall health and endocrine function of wild brown bullhead (ameiurus nebulosus) and goldfish (carassius auratus) from the wheatley harbour area of concern (lake erie, ontario, canada) was assessed using a suite of physiological and biochemical endpoints. smaller gonads were detected in female brown bullhead and goldfish from wheatley harbour compared with hillman marsh (ontario, canada) reference fish. female brown bullhead exhibited decreased in vitro synthesis of 17β-estradiol. female go ... | 2012 | 23027428 |
pathogenesis of skin and liver neoplasms in white suckers from industrially polluted areas in lake ontario. | increased prevalences of epidermal and hepatobiliary neoplasms in white suckers (catostomu commersoni) and brown bullheads (ictalurus nebulosus) in the western region of lake ontario have been associated with industrial pollution, but the identity and causative role of environmental carcinogens have not yet been established. most epidermal tumors of lip and body skin are benign focal proliferations that occur in fish from the polluted hamilton region, and also in fish from less polluted sites in ... | 1990 | 2360036 |
