In order to assess the spatial and temporal patterns of the a-, b- and g-isomers of hexachlorocyclohexane (HCH) in the arctic biotic and abiotic environment, it is proposed that: (1) concentrations and ratios of HCH isomers be compared over time in air, water, seals, beluga, polar bears and seabirds to determine any shifts in isomeric ratios and how those shifts interrelate among the various media, and (2) concentrations and ratios of HCH isomers be compared spatially in the abiotic and biotic media and reasons for any patterns explored.
In order to address the the question of utility of arctic seabird eggs as an indicator of contaminant temporal trends, it was proposed that: (1) archived arctic seabird egg contents be re-analyzed for organochlorines according to a standardized pooling and analytical protocol in order to confirm whether those residues have been decreasing since the mid-1970s, (2) archived arctic seabird egg contents be analyzed for mercury and selenium to determine whether or not those levels have been increasing or decreasing since the mid-1970s, (3) egg contents and adult livers be analyzed by full scan and ICP to identify any "new" or previously unidentified organochlorines (MS full scan) or metals (ICP) which may have entered the Canadian arctic food chain.
1) To determine tissue residue levels of organochlorines and metals in arctic fox feeding in or near an arctic coastal environment. 2) To assess whether or not residue levels found in arctic fox pose a potential wildlife health risk. 3) As part of a pilot project, to determine residue levels and assess potential wildlife health risk to wolverines feeding in or near a coastal environment.
Project monitors bioaccumulation of chlorine compounds and other toxics in mussels in waters below paper industry. In case, where industry has quit (Kemijärvi) information of chemical ecosystem restoration is attained. Project is managed by Finnish Environmental Institute (SYKE).
The general objective of the human health sub-programme is to protect and promote the health of Arctic peoples, especially children, with respect to exposure environmental contaminants.
The overall objectives for operation of the station will follow those defined in the AMAP programme. The main interests are the levels and trends of airborne toxic pollutants (POPs and heavy metals) in northern Fennoscandia.
National Environmental Monitoring in Sweden. Monitoring of persistent organic compounds (POP) in fish. Monitoring proceeds in 110 lakes in entire Sweden (10 lakes are located in AMAP area) annually. Three fish species are selected: Arctic char (Salvelinus alpinus), Northern pike (Esox lucius), and Perch (Perca fluviatilis). Fish are sampled, prepared, and stored in the specimen bank in Swedish Museum of Natural History. POP like PCB, HCH, HCB, DDT, PBDE are analysed.
National Environmental Monitoring Programme in Sweden. Measurements of persistant organic pollutants in the air and depositions are carried out at Råö, Vavihill, Aspvreten, and in Pallas (North Finland). The monitoring programme includes measurements of: polycyclic aromatic hydrocarbons (PAH), polychlorinated biphenyls (PCB), some pesticides (HCH, DDT) and polybrominated diphenylethers (PBDE).
The project is a continuation of the monitoring activities of the AMAP POPs and Heavy metals programme in marine, terrestrial and freshwater environments of the Faroe Islands. The aims of the programme is to establish data for timetrend and spatial assessments as well as providing data of importance in human health risk assessment on mercury and POPs. The programme incorporates analyses on pilot whale, cod, black guillemots from the marine environment, sheep and hare from the terrestrial environment and arctic char from the freshwater environment. The compounds analysed are "legacy" POPs and mercury, cadmium and selenium. In addition, a retrospective analyses of PFOS in pilot whale tissues going back as far as possible (ie.1986) is part of the project.
The IPY-project ‘COPOL’ has a main objective of understanding the dynamic range of man-made contaminants in marine ecosystems of polar regions, in order to better predict how possible future climate change will be reflected in levels and effects at higher trophic levels. This aim will be addressed by 4 integrated work packages covering the scopes of 1) food web contaminant exposure and flux, 2) transfer to higher trophic levels and potential effects, 3) chemical analyses and screening, 4) synthesis and integration. To study the relations between climate and environmental contaminants within a project period of four years, a “location-substitutes-time”-approach will be employed. The sampling is focussed towards specific areas in the Arctic, representing different climatic conditions. Two areas that are influenced differently by different water masses are chosen; the Kongsfjord on the West-coast of Spitzbergen (79N, 12 E) and the Rijpfjord North-East of Svalbard (80N, 22 E). The main effort is concentrated in the Kongsfjord. This fjord has been identified as particularly suitable as a study site of contaminants processes, due to the remoteness of sources, and for influences of climatic changes, due to the documented relation between Atlantic water influx and the climatic index North Atlantic Oscillation (NAO). The water masses of the Rijpfjord have Arctic origin and serves as a strictly Arctic reference. Variable Atlantic water influx will not only influence abiotic contaminant exposure, but also food web structure, food quality and energy pathways, as different water masses carry different phyto- and zooplankton assemblages. This may affect the flux of contaminants through the food web to high trophic level predators such as seabirds and seals, due to altered food quality and energy pathways.
In addition to the persistent organic pollutants (POPs) analysed in former monitoring projects, other compounds of concern have been identified by the international community (e.g. OSPAR, AMAP), and analytical methods have been developed. These compounds include brominated flame retardants (BFRs), phthalates, polychlorinated naphthalenes (PCNs), perfluorooctane sulfonate (PFOS) and synthetic musk compounds. The aim of this project is to screen the marine environment of East and West Greenland and the Faroe Islands for these compounds. The analyses will be based on existing samples of pilot whale and fulmars from the Faroe Islands as well as marine sediments, shorthorn sculpins, ringed seals, minke whales from West Greenland and shorthorn sculpins, ringed seals and polar bears from East Greenland. As several trophic levels of the marine Arctic food chain are taken into account, the project will also result in information on the bioaccumulation of these compounds.
The primary scope of the project is to investigate the long-term time trend of brominated flame retardants for the contamination and possible effects in relation to the contamination of peregrine falcon eggs. The contamination by the conventional POP compounds will also be identified. Totally 36 out of 53 collected eggs will be analysed. Time trend analysis will be performed based on a multi-variant methodology for a period of 18 years. The result will contribute to the assessment of organic pollutant contaminationm in Greenland including the effect on vulnerable wild life.
Polar bears are at the top of the arctic marine food chain. Owing to the high lipid content of their diet, polar bears appear particularly prone to bioaccumulate organochlorines. Polar bears from East Greenland and Svalbard have higher contaminant levels than polar bears elsewhere in the Arctic. Levels of PCBs in these areas might negatively affect reproduction and survival. So far more than 130 polar bear samples have been collected since 1999. These samples are being analysed for organochlorines and pathological effects.
The project includes analyses of PCBs, organochlorine pesticides, chlordanes and brominated flame retardants in seals, birds and fish from Greenland. The programme covers a period of five years to investigate temporal trends in the concentration levels of organic pollutants in Greenland.
Organochlorines (OCs) concentrate through the arctic marine food webs and are stored in the adipose tissue due to their high lipophilic and persistent characteristics. The polar bears receive high doses of POPS through their diet and a controlled experimt was need to resolve effect on the immune system and effects on internal organs. Such a controlled experiment on sledge dogs as a replacement test organism for the polar bear was conducted from 2004-2006 to investigate dose-response effects.
The project studies the development through time of contaminants (heavy metals and organic pollutants) in animals in Greenland.
Arctic animals utilize periods with high food availability for feeding and lipid deposition, whereas they rely on stored lipids during unfavorable periods. Hence, many arctic inhabitants exhibit profound seasonal cycles of fattening and emaciation. In the Arctic, feeding is associated with fat deposition and contaminant accumulation. When lipids are mobilized, accumulated contaminants are released into the circulation. Consequently, blood contaminant concentrations may increase markedly and result in a redistribution of the contaminant(s) from “insensitive”, adipose tissues to sensitive organs, and increased contaminant bioavailability. Such variations complicate interpretations of pollutant toxicity, both in effect studies and in monitoring programs, and remains an important future reseach area. In the present study, we will use arctic fox (Alopex lagopus) as a model species for investigating tissue distribution and bioavailability of organochlorine contaminants (OCs) in relation to natural variations in lipid status (field study). These data will be supplemented and validated through a contamination study with blue fox (A. lagopus), where the seasonal changes in lipid status of wild fox are simulated in the laboratory. In both the field and laboratory study, possible effects of OCs on steroid hormone synthesis, and plasma levels of hormones, vitamin E and retinol will also be assessed.
In order to evaluate the capacity of mussels to accumulate pollutants and to enhance growth and physiological effects, an investigation was carried out in the Faroe Islands and in the Skagerrak. In March 2000, about 1500 mussels of proper dimensions (length ranging between 5 and 6 cm) were collected in the Kaldbak Fjord (Faroe Islands) on a 10m water column. Selected mussels were divided in 4 groups (320 each) and deployed in 4 different stations (one at the Faroe Islands and three in the Skagerrak). Semipermeable membrane devices (SPMDs) were also deployed in the same stations for the preconcentration of lipophilic pollutants. One month later (end of April-beginning of May) mussels and SPMDs were recollected and sent to different laboratories for the determination of various parameters.
