Abstract
The results of studies of the heavy metal background level in the natural environment ofthe Qaumarujuk and Agfardlikavså fjords, adjacent to the lead-zinc mine Sorte Engel (= Black Angel) near Mârmorilik (71°07'N, 51°16'W), have been briefly communicated by Bondam & Asmund (1974), Asmund (1975), Bohn (1975) and BoIlingberg (1975). FuHdetails of the analyticaI results of these surveys have been reported in Danish elsewhere. (Vandkvalitetsinstituttet 1972; Grønlands Fiskeriundersøgelser et al., 1974; GGU et al., 1975). Since then, renewed sampling has been carried out, both in February and August 1974, and in April and September 1975, in order to follw closely the environmental dissemination of some heavy metals in the fjord region, due to disposal of tailings from the flotation plant adjacent to Agfardlikavsåfjord (fig. 18). This short communication deals with the content of certain heavy metals of bottom sediments, biological tissues and samples of sea water in the fjord regime after full production started in October 1973.
Highlights
The rate of accumulation indicates that the influence of the tide on its deposition is negligible. , In order to ~ccount for the transportation of solids in suspe'nsion, the grain size of the solid waste has been determined, as shown in fig
With the lowest density ofthe sulphides in question, sphalerite will be the main indicator for the gradual dissemination of particulate heavy metals in the fjord system
Earlier reports show the amounts of various heavy metals in organic samples before mining commenced (VandkvalitelsinstituUet, 1972; Grønlands Fiskeriundersøgelser et al, 1 9 7 4 ) . ' ;,' _
Summary
At station 3 the Zn content has been determined with an accuracy of ± 30 ppm Locali ty
