| northern fulmars as biological monitors of trends of plastic pollution in the eastern north pacific. | marine plastic debris is a global issue, which highlights the need for internationally standardized methods of monitoring plastic pollution. the stomach contents of beached northern fulmar (fulmarus glacialis) have proven a cost-effective biomonitor in europe. however, recent information on northern fulmar plastic ingestion is lacking in the north pacific. we quantified the stomach contents of 67 fulmars from beaches in the eastern north pacific in 2009-2010 and found that 92.5% of fulmars had i ... | 2012 | 22738464 |
| plastic ingestion by the northern fulmar (fulmarus glacialis) in iceland. | in 2011, northern fulmars (fulmarus glacialis) from iceland were used to test the hypothesis that plastic debris decreases at northern latitudes in the atlantic when moving away from major human centres of coastal and marine activities. stomach analyses of icelandic fulmars confirm that plastic pollution levels in the north atlantic tend to decrease towards higher latitudes. levels of pollution thus appear to link to regions of intense human coastal and marine activities, suggesting substantial ... | 2012 | 22455662 |
| halogenated organic contaminants and their correlations with circulating thyroid hormones in developing arctic seabirds. | thyroid hormones are essential for normal growth and development and disruption of thyroid homeostasis can be critical to young developing individuals. the aim of the present study was to assess plasma concentrations of halogenated organic contaminants (hocs) in chicks of two seabird species and to investigate possible correlations of hocs with circulating thyroid hormone (th) concentrations. plasma from black-legged kittiwake (rissa tridactyla) and northern fulmar (fulmarus glacialis) chicks we ... | 2012 | 22154184 |
| effects of seabird vectors on the fate, partitioning, and signatures of contaminants in a high arctic ecosystem. | seabirds bioaccumulate contaminants from prey, transport them to their nesting sites, and deposit them in their excreta and carcasses, thereby focusing marine-derived contaminants into remote, terrestrial receptor sites. in the case of organochlorine chemicals transported by northern fulmars (fulmarus glacialis) to a high arctic seabird colony on devon island, nunavut, canada (76°13'n, 89°14'w), this contaminant pathway dominates all others. in freshwater ponds below the nesting cliffs, concentr ... | 2011 | 22026353 |
| monitoring plastic ingestion by the northern fulmar fulmarus glacialis in the north sea. | the abundance of plastics in stomachs of northern fulmars from the north sea is used in the ospar ecological quality objective (ecoqo) for marine litter. the preliminary ecoqo defines acceptable ecological quality as the situation where no more than 10% of fulmars exceed a critical level of 0.1 g of plastic in the stomach. during 2003-2007, 95% of 1295 fulmars sampled in the north sea had plastic in the stomach (on average 35 pieces weighing 0.31 g) and the critical level of 0.1 g of plastic was ... | 2011 | 21737191 |

| biomarker responses associated with halogenated organic contaminants in northern fulmars (fulmarus glacialis) breeding in the canadian arctic. | we examined relationships between hepatic concentrations of halogenated organic contaminants and ethoxyresorufin o-deethylase (erod) activity and retinoid (vitamin a) concentrations in livers, as well as retinol and thyroid hormone (tt(3), tt(4)) levels in blood plasma, of northern fulmars at two breeding colonies in the canadian high arctic. biomarker levels or responses did not differ significantly between males and females at either colony, nor was there any significant difference between col ... | 2011 | 21571413 |
| relationship between persistent halogenated organic contaminants and tcdd-toxic equivalents on erod activity and retinoid and thyroid hormone status in northern fulmars. | we investigated whether the hepatic cytochrome p450 1a activity (measured as 7-ethoxyresorufin-o-deethylase (erod)) and plasma thyroid hormone and liver retinoid concentrations were explained by liver and blood levels of halogenated organic contaminants (hocs) in free-ranging breeding northern fulmars (fulmarus glacialis) from bjørnøya in the norwegian arctic. hepatic erod activity and liver levels of 2,3,7,8-tetrachlorodibenzo-p-dioxin toxic equivalents (teqs) were positively correlated, sugges ... | 2010 | 20888620 |
| persistent halogenated organic contaminants and mercury in northern fulmars (fulmarus glacialis) from the canadian arctic. | northern fulmars from two breeding colonies in the canadian arctic, cape vera and prince leopold island, were analyzed for organochlorine pesticides, pcbs, perfluorinated compounds (pfcs) and total mercury (hg). hepatic concentrations of organochlorines and hg were highest in the male fulmars from cape vera. perfluorooctane sulfonate (pfos) concentrations did not vary significantly between sexes or colonies. however, concentrations of the perfluorinated carboxylates (pfcas) were higher in fulmar ... | 2010 | 20863605 |
| contamination of an arctic terrestrial food web with marine-derived persistent organic pollutants transported by breeding seabirds. | at cape vera, devon island (nunavut, canada), a colony of northern fulmars (fulmarus glacialis) concentrates and releases contaminants through their guano to the environment. we determined whether persistent organic pollutants (pops) from seabirds were transferred to coastal food webs. snow buntings (plectrophenax nivalis) were the most contaminated species, with ∑pcb and ∑ddt (mean: 168, 106 ng/g ww) concentrations surpassing environmental guidelines for protecting wildlife. when examined colle ... | 2010 | 20801564 |
| preliminary assessment of avian stomach oils: a vector of contaminants to chicks and potential for diet analysis and biomonitoring. | bird species from the order procellariiformes or petrels, including the northern fulmar (fulmarus glacialis), produce high lipid and high energy content stomach oils from the prey they consume, which enables them to exploit distant marine food sources. stomach oils are also used as a food source for chicks and for defensive purposes. samples of stomach oils from two arctic colonies, st. george island alaska, usa and cape vera, devon island nunavut, canada, were collected and analyzed for organoc ... | 2010 | 20707316 |
| biotransformation of pcbs in arctic seabirds: characterization of phase i and ii pathways at transcriptional, translational and activity levels. | arctic seabirds are exposed to a wide range of halogenated organic contaminants (hocs). exposure occurs mainly through food intake, and many pollutants accumulate in lipid-rich tissues. little is known about how hocs are biotransformed in arctic seabirds. in this study, we characterized biotransformation enzymes in chicks of northern fulmars (fulmarus glacialis) and black-legged kittiwakes (rissa tridactyla) from kongsfjorden (svalbard, norway). phase i and ii enzymes were analyzed at the transc ... | 2010 | 20176133 |
| an isotopic investigation of mercury accumulation in terrestrial food webs adjacent to an arctic seabird colony. | at cape vera (devon island, nunavut, canada), a seabird colony of northern fulmars (fulmarus glacialis) congregates and releases nutrients through the deposition of guano to the coastal terrestrial environment, thus creating nutrient-fertilized habitats important to insects, birds, and mammals. here we determined whether mercury was similarly enriched in various terrestrial food web components in this high arctic coastal ecosystem due to seabird inputs. stable isotopes (delta(15)n, delta(13)c) w ... | 2010 | 20153017 |
| polychlorinated naphthalenes in polar environments--a review. | polychlorinated naphthalenes (pcns) consist of naphthalene substituted with 1-8 chlorines, yielding 75 possible congeners. they were formerly used in industry, occur at trace levels in commercial pcb mixtures, and have current sources in combustion processes. pcns are widespread in arctic air with higher levels in the european arctic. concentrations were higher during the cold months in arctic canada and russia, but no seasonality was noted in subarctic canada and greenland.

| high arctic ponds receiving biotransported nutrients from a nearby seabird colony are also subject to potentially toxic loadings of arsenic, cadmium, and zinc. | the role of northern fulmars (fulmarus glacialis) was investigated for the transport of nutrients and trace elements to a series of 10 ponds located along a gradient of seabird influence below a fulmar colony in the high arctic (cape vera, devon island, canada). phosphorus, cd, k, zn, and as were identified as seabird-derived elements, having both a high concentration in fulmar guano and a low concentration in background pond sediments (i.e., a high biogenic enrichment factor). fluxes of these e ... | 2009 | 19604032 |
| fatty acid signatures of stomach oil and adipose tissue of northern fulmars (fulmarus glacialis) in alaska: implications for diet analysis of procellariiform birds. | procellariiforms are unique among seabirds in storing dietary lipids in both adipose tissue and stomach oil. thus, both lipid sources are potentially useful for trophic studies using fatty acid (fa) signatures. however, little is known about the relationship between fa signatures in stomach oil and adipose tissue of individuals or whether these signatures provide similar information about diet and physiology. we compared the fa composition of stomach oil and adipose tissue biopsies of individual ... | 2007 | 17712565 |
| halogenated organic contaminants and mercury in northern fulmars (fulmarus glacialis): levels, relationships to dietary descriptors and blood to liver comparison. | the northern fulmar (fulmarus glacialis) is an interesting candidate for the study of patterns and levels of halogenated organic contaminants (hocs) since they accumulate high levels of certain hocs. in the present study we characterized a suite of established and novel hocs in northern fulmars breeding on bjørnøya in the norwegian arctic. a comparison between blood and liver hoc levels was made, and the levels were related to the ratios of heavier to lighter stable isotopes of nitrogen (15)n/(1 ... | 2007 | 17000037 |
| levels of brominated flame retardants in northern fulmar (fulmarus glacialis) eggs from the faroe islands. | eggs from northern fulmars (fulmarus glacialis) were sampled in the faroe islands. the content of the brominated flame retardants tri- to decabromodiphenyl ethers (bdes) and 1,2-bis(2,4,6-tribromophenoxy)ethane (btbpe) were determined in nine samples in concentrations ranging from non-detectable to 7 ng g-1(l.w.). the bde levels were similar as in an earlier study of bde levels in the fulmar eggs from the faroe islands but 10-1000 times lower compared to studies of eggs from seabirds and birds o ... | 2006 | 16753200 |
| polybrominated diphenyl ethers and traditional organochlorine pollutants in fulmars (fulmarus glacialis) from the faroe islands. | the observed high-level burdens of organohalogens among the residents of the faroe islands, needs to be explained. long-finned pilot whale (globicephala melas) blubber and meat are known sources of environmental exposure. the present study focus on the organohalogen contamination of the fulmar (fulmarus glacialis). the compounds quantified in fulmar muscle, fat, and egg are pcbs, ddts, hexachlorobenzene (hcb), and polybrominated diphenyl ethers (pbdes). the dominating pollutants are the 4,4'-ddt ... | 2005 | 15992590 |
