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.
The project aims at establishing a long-term Arctic-Antarctic network of monitoring stations for atmospheric monitoring of anthropogenic pollution. Based upon the long and excellent experiences with different scientific groups performing air monitoring within the Arctic Monitoring and Assessment Programme (AMAP), an expanded network will be established including all AMAP stations and all major Antarctic “year-around” research stations. As an integrated project within the “International Polar Year 2007-08” initiative, the ATMOPOL co-operation intend to • Establish a long-term coordinated international Arctic-Antarctic contaminant programme. • Develop and implement a joint sampling and monitoring strategy as an official guideline for all participating stations. • Support bi-polar international atmospheric research with high-quality data on atmospheric long-range transport of contaminants (sources, pathways and fate). • Support future risk assessment of contaminants for Polar Regions based on effects of relevant contamination levels and polar organisms Based upon the well-established experiences of circum-Arctic atmospheric contaminant monitoring in the Arctic under the AMAP umbrella, a bi-polar atmospheric contaminant network will be established and maintained. In conjunction with the polar network of atmospheric monitoring stations for air pollution, surface-based and satellite instrumentation will be utilised to provide the characterization of the Arctic atmospheric-water-ice cycle. Together with numerical weather prediction and chemical transport model calculations, simultaneous measurements of pollutants at various locations in the Arctic and Antarctic will enhance our understanding of chemical transport and distribution as well as their long-term atmospheric trends. In addition to investigating the importance of atmospheric transport of pollutants an understanding of the transference and impact of these pollutants on both terrestrial and marine environments will be sought. A secretariat and a “scientific project board” will be established. During this initial phase of the project (2006), a guideline on priority target compounds, sampling strategies, equipment and instrumentation, analytical requirements, as well as quality assurance protocols (including laboratory intercalibration exercises) will be developed and implemented. The ATMOPOL initiative aims to address highly relevant environmental change processes and, thus, will strive to answering the following scientific questions: • How does climate change influence the atmospheric long-range transport of pollutants? • Are environmental scientists able to fill the gaps in international pollution inventories and identification of possible sources for atmospheric pollution in Polar Regions? • What are the differences in transport pathways and distribution patterns of various atmospheric pollutants between Arctic and Antarctic environments? Why are there such differences? What is the final fate of atmospherically transported pollutants and how does this impact on the environment and indigenous people?In order to understand the underlying atmospheric chemistry of pollution, e.g. atmospheric mercury deposition events, routine surface measurements of UV radiation as well as campaign related measurements of UV radiation profiles will also be included.The project will establish a cooperative network on atmospheric contaminant monitoring in Polar Regions far beyond the IPY 2007/08 period and is, thus, planned as an “open-end” programme. All produced data will be available for all participating institutions for scientific purposes as basis for joint publications and reports from the ATMOPOL database to be developed.
The objectives of this study are to determine temporal trends of persistent organic pollutants (POPs) and metals, especially mercury, in landlocked Arctic char in Char Lake and Resolute Lake by analysis of annual sample collections, to investigate factors influencing contaminant levels in landlocked char such as the influence of sampling time, water temperature and diet, and to provide this information on a timely basis to the community of Qausuittuq (Resolute). The rationale is that small lakes in the high arctic are replenished annually with snowmelt runoff and direct precipitation which represent significant fractions of their water budgets. Declining concentrations of POPs, or increasing levels of previously unstudied POPs, in air and precipitation should be reflected relatively quickly in changes in levels in food webs and top predator fishes, compared to the vast marine environment. We know this to be the case from the sedimentary record of POPs and mercury in small arctic lakes. This project collects landlocked arctic char from lakes near Resolute annually and analyses them for mercury, a suite of other metals as well as persistent organic pollutants (PCBs, organochlorine pesticides including toxaphene). Results will be compared over time. The first samples were collected from Char and Resolute Lakes in 1992/93. The next set were collected in 1997 and annually since then. Char are being collected from several lakes in the area because of limited sample numbers in some lakes and the possibility of local influences. Samples are also being archived for future analyses.
The objective of this project is to study long term temporal trends of persistent organic pollutants and mercury in ringed seals from the Canadian arctic. The project rationale is that there are previous results for POPs and mercury in ringed seal tissues for many locations. Furthermore there may be regional differences in temporal trends due to geographical differences in POPs and mercury in marine waters and food webs within the Canadian arctic. It is relatively cost efficient to return to the same locations for additional samples using the same sampling and anlaysis protocols are were used in previous studies (see AMAP and Canadian Assessment Reports). Samples are being collected with the help of hunters and trappers organizations in each community. During 2000-01 samples are being collected at Resolute, Arctic Bay and Pond Inlet. The study will also analyse samples collected recently (1998/99) from Pangnirtung, Arviat and Grise Fiord. Results will be compared with previous data which the Principal Investigator generated in the 1980's and early 1990's. Preliminary results will be available in mid-2001.
The objectives of this project are: A) to determine whether atmospheric concentrations and deposition of priority pollutants in the Arctic are changing in response to various national and international initiatives by: i) continuing to measure the occurrence of selected organochlorines in the arctic atmosphere at Alert, NWT for a period of three more years (measurements started in 1992), in parallel with identical measurements in western Russia at Amderma; ii) sampling at the Kinngait (Cape Dorset) station in 2000/2001 for the purpose of detecting change in the eastern Canadian Arctic by comparison with observations made four years earlier (1994-1996) at this site; and iii) analyzing and reporting data from Alert, Tagish, Kinngait and Dunai Island thereby providing insight into pollutant trends and sources. B) Ensuring the effective utilization of information at the international negotiating table in order to achieve the appropriate restrictions on release of pollutants of concern for the arctic environment by: i) contributing to the next assessment arising from the second phase of the Northern Contaminants Program (Canada) and specifically, the revised Assessments on POPs and Heavy Metals as part of the Arctic Monitoring and Assessment (AMAP) Program Work Plan; and ii) advising Canadian negotiators in preparing reasonable, practical strategies of control.
The objectives of this project are A) to determine coplanar polychlorinated biphenyls (PCBs), polychlorinated naphthalenes (PCNs), brominated diphenyl ethers (BDPEs), chlorophenolic compounds and chloroparaffins in air from arctic monitoring stations; and B) to search for other "new" chemicals in the arctic environment, not currently monitored by Canada's Northern Contaminants Program (NCP) but of potential concern based on known persistence, extent of usage and toxicology.
