Terrestrial TDC

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, and black guillemots from the marine environment, sheep from the terrestrial environment and arctic char from the freshwater environment. The compounds analysed are "legacy" POPs and mercury, cadmium and selenium. In addition, PFAS and PBDEs were analysed in pilot whale tissues, to add to previously established time-trend series.

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 project studies the development through time of contaminants (heavy metals and organic pollutants) in animals in Greenland.

Contaminants were examined for trends over time, spatial variation based on disparate breeding areas, and relationships with measures of productivity. Most organochlorines and metals declined over time. Mercury was the only contaminant with possibly increasing concentrations in eggs. Egg and feather samples collected in 2000 will provide more information on mercury trends and effects. This study embodies 20 years of data on environmental contaminants in peregrine falcons nesting in Alaska.

We compared animals from a caribou (Rangifer tarandus) mortality event in the area of Point Hope and Chariot (Cape Thompson), Alaska (USA) in 1995 to hunter-killed caribou from reference sites (Barrow, Red Dog Mine, and Teshekpuk Lake, Alaska). Gross and histologic endpoints, and element levels (As, Cd, Cu, Pb, Zn, Fe) were evaluated. Starvation/malnutrition were major factors leading to death or severe weakness as very little or no fat (very low body condition scores) and serous atrophy of fat (marrow cavity and histologically) were more prevalent in caribou associated with the mortality event as compared to reference sites animals. Accumulation of hepatic hemosiderin in Kuppfer cells was noted as an indicator of cachexia. Levels of lead in feces and liver, copper the rumen contents, and arsenic in muscle were higher in caribou harvested near Red Dog Mine and might be expected in the mineral rich area, but were not at a level of concern for toxicoses. Kidney levels of cadmium were significantly increased with increasing age, and presents a potential concern for human consumers, and is an expected finding. We concluded that heavy metals played no role in the mortality event and that caribou starved. Further investigation of regional minerals differences is required to understand the sources and transport mechanisms to explain these findings and to properly address mining activity impacts. Mortality events on the north slope of Alaska are not uncommon and likely involve starvation as described here, but in most cases are not investigated, even though recent industrial activities have heightened concern.

Brief: Assessment of the significance of aquatic food chains as a pathways of exposure of indigenous peoples to PTS, assessment of the relative importance of local and distant sources, and the role of atmospheric and riverine transport of PTS in Northern Russia. Project rationale and objectives: (1) To assess levels of Persistent Toxic Substances (PTS) in the environment in selected areas of the Russian North, their biomagnification in aquatic and terrestrial food chains, and contamination of traditional (country) foods that are important components of the diet of indigenous peoples. (2) To assess exposure of indigenous peoples in the Russian North to PTS, and the human health impacts of pollution from local and remote sources, as a basis for actions to reduce the risks associated with these exposures. (3) To inform indigenous peoples about contamination by PTS of their environment and traditional food sources, and empower them to take appropriate remedial actions to reduce health risks. (4) To enhance the position of the Russian Federation in international negotiations to reduce the use of PTS, and to empower the Russian Association of Indigenous Peoples of the North (RAIPON) to participate actively and fully in these negotiations. Project activities to achieve outcomes: (1) Inventory of local pollution sources in the vicinities of selected indigenous communities. (2) Survey of levels and fluxes of PTS in riverine and coastal marine environment important for indigenous peoples living in these environments and using them for their subsistence; and assessment of fluxes of PTS to these environments via selected rivers and the atmosphere. (3) Dietary surveys of selected indigenous communities. (4) Study of biomagnification, based on measurements of selected PTS in representative species in food chains important for the traditional diet of indigenous populations. (5) Survey and comparative assessment of pollution levels of the indigenous and general population in selected areas. (6) Dissemination of results to all relevant stakeholders.

To monitor levels of pollutants in merlin by analysis of POPs and heavy metals in eggs and feathers. /Feathers and addled eggs of merlin were collected in 1992, 1993, 1994, 1999 and 2000 for chemical analysis of POPs and heavy metals. Comparisons with eggs from museum collections show that there has been a significant shell thinning in eggs of Norwegian merlins. From 1947 up to 1990 the eggs were on average ca. 15% thinner than normal and after 1990 the thinning has been ca. 10%. There are still high concentrations of DDE to reduce reproductive output in some cases. The PCB levels are low compared to the DDE levels and the concentrations of other chlorinated hydrocarbons are also low. Results from mercury analyses indicate possible effects on breeding performance in some adults.

Moose (Alces alces) found dead (FD) and hunter-killed (HK) in 1995 on the north slope of Alaska (Colville River drainage) were evaluated for heavy metal and mineral status. Compared to previous reports for moose and domestic cattle, and data presented here from Alaska moose outside the Colville River area, levels of copper (Cu) were determined to be low in hoof, hair, liver, kidney, rumen contents, and muscle for these north slope moose. Iron (Fe) was low in muscle as well. These findings, in conjunction with evidence of poor calf survival and adult mortality prompted investigation of a mineral deficiency in moose (serum, blood, and hair) captured in the spring of 1996 and 1997. Captured males had higher Ca, Zn and Cu levels in hair than captured females. Female moose hair samples were determined to be low (deficient) in Cu, Ca, Fe, and Se with mean levels (ppm) of 2.77, 599.7, 37.4, and 0.30, respectively. Serum Cu level was low, and to a lesser degree Zn was deficient as well. Whole blood (1997 only) was marginally deficient in Se and all animals were deficient in Cu. Based on whole blood, sera and hair, Cu levels were considered low for moose captured in spring 1996 and 1997 in the Colville River area as compared to published data and other populations evaluated in this study. Low levels of ceruloplasmin activity support this Cu deficiency theory. Evidence indicates that these moose are deficient in Cu and other minerals; however, the remote location precluded sufficient examination of animals to associate this apparent deficiency with direct effects or lesions. Renal levels of Cd increased with age at expected levels.

The monitoring is focused on risk assessment of LRTAP -type substances in terrestrial foodchains of the Boreal and subarctic environment. The concentration levels in precipitation, in the soil humus and in the indicator species (e.g. red woodants, common shrew) are studied annually in the seven areas locating in the Southern, Middle and Northern Finland. Possible gradients and changes in concentration levels between the Southern and Northern environments will be a part of the base data for risk assessment and pollution development in Finland.

According to the national residue control programme heavy metals (lead, cadmium, mercury) and organochlorine compounds (HCH, HCB, DDT, PCB, etc) are analyzed from the samples. Investigations are done according to the Council Directive 96/23/EC.
