Directory entires that have specified Greenland as one of the geographic regions for the project/activity and are included in the AMAP, ENVINET, SAON and SEARCH directories. Note that the list of regions is not hierarchical, and there is no relation between regions (e.g. a record tagged with Nunavut may not be tagged with Canada).

1. Health Behaviour in School-aged Children in Greenland (HBSC Greenland)

The HBSC network is a WHO supported research network on health and health behaviour in schoolaged children performing surveys every 4 years in 41 countries. The data are used in monitoring, research and health promotion. Network type: - Research network - Child health - Human & socio-economic - Location(s): Greenland and 40 other countries…..

2. Temporal assessment of Arctic pollution of mercury and persistent organic pollutants using lake sediments

The general objective is to assess time trends and deposition loads of mercury and persistent organic pollutants from long-range atmospheric transport in Arctic environments (Greenland and north Swedish mountains) using lake sediments. The specific aims are: 1. Mercury - Study pre-industrial and industrial temporal changes in Hg concentrations in sediment records of remote lakes in Greenland and north Swedish mountains. - Address the hypothesis of 'cold condensation' (the progressive re-volatilization in relatively warm locations and subsequent condensation and deposition in cooler environments) of mercury, using a series of lake sediment cores along climate gradients: in Greenland from the inland ice sheet towards the coast and in the Swedish mountains from high altitudes down to the boreal forest. 2. POPs - Make a screening to establish which persistent organic pollutants are present in recent lake sediments in remote sites in Greenland and the north Swedish mountains. Besides PCBs, HCH, DDT and other pesticides, there are new environmental threats such as brominated flame retardants, such as PDBEs, which are of particular interest. The increasing use of PBDE and other brominated compounds may lead to increasing concentrations in the Arctic environment. However, very little is known about the levels of PBDEs as well as other POPs in sediments from the Arctic. - Analyse test series of selected POPs using a lake sediment core to assess temporal trends and a number of surface sediment samples from different lakes to assess spatial variability in concentrations and cumulative fluxes of POPs in Greenland and Swedish mountain lakes. - The main purpose of this pilot study of POPs is to determine the concentrations of selected POPs in sediments from Greenland and the northern Swedish mountains and to assess how useful lake sediments are for studying temporal and spatial pollution loads of POPs in Arctic environments.

3. Monitoring and Modelling of Atmospheric Pollution in Greenland

In 2000 it is proposed to operate an atmospheric programme consisting of a monitoring and a modelling part and composed of 3 programme modules. The monitoring programme consists of two parts. I. It is proposed to continue the weekly measurements of acidifying components and heavy metals at Station Nord in north-east Greenland for assessment of atmospheric levels and trends. The measuring programme includes also highly time resolved measurements of Ozone and of total gaseous Mercury (TGM). The results will also be used for continued development and verification of the transport model calculations. Receptor modelling of the pollution composition will be used for identification and quantification of the source types that influence the atmospheric pollution in north-east Greenland. Comparison of the two sets of modelling results is expected to give better models. II. The purpose of the project is the operation of a permanent air monitoring programme in the populated West Greenland at a location which is representative for transboundary air pollution. The most promising sites are located in the Disko Bay area and in the vicinity of Nuuk. The objectives are to obtain data on the concentration levels of air pollutants that can be used for assessing seasonal variations and trends and for studying long range transport of pollutants mainly from North America to West Greenland. The purpose is further to provide data for development and improvement of long range transport models that can be used to identify the origin of the pollution and its transport pathways. The results from measurements and model calculations will be used to assess the magnitude of deposition to sea and land in this populated region of Greenland. III. In the proposed modelling programme the operation, application and maintenance of the current basic hemispheric model will be continued. Results on origin, transport, and deposition of contaminants on land and sea surfaces in the Arctic are essential for interpretation and understanding the Arctic air pollution. The model will be developed to improve the spatial and temporal resolutions, as well as the accuracy by including physically and mathematically better descriptions of the key processes treated in the model. The work to expand the model to include also non-volatile heavy metals, such as Cadmium and Lead on an hemispheric scale will be continued. Since the atmospheric chemistry of Ozone and Mercury seem to be strongly connected in the Arctic it is planned to continue the development and testing of a model module for hemispheric transport and chemistry for ozone and mercury to assess the origin and fate of this highly toxic metal in the Arctic.
