Mercury accumulation rates and spatial patterns in lake sediments from West Greenland: a coast to ice margin transect

Article Abstract:

The study examines sediments from 21 lakes in the Arctic ranging from the coast of the ice sheet margin in the Sondre Stromford area, for the determination of transport of contaminants, such as mercury. These contaminants are from the industrial areas located at lower latitudes.

The case for atmospheric mercury contamination in remote areas

Article Abstract:

Mercury contamination in aquatic and wildlife environments was found to be caused by the deposition of human-related emissions and fish product consumption. It was also established that biological aggregation of mercury is triggered by chemical reactions involving trace amounts of mercury in the atmosphere and in bodies of water. Contrary to popular beliefs, the application of diagenic processes is ineffectual in evaluating the causes and determining the sources of mercury contamination.

Natural lead concentrations in pristine boreal forest soils and past pollution trends: a reference for critical load models

Article Abstract:

In order to set realistic goals for atmospheric pollution deposition in soil it is essential to evaluate pre-industrial pollutant levels. This study examines soils from southern Sweden to derive calculations of soil chemistry for the last 5,500 years.
