Abstract
Through the ages has heavy metal been emitted into the environment due to various causes. This includes human action such as protective paints on ships and emissions from transport and its infrastructure. These heavy metals would then be found in the different environments. One such environment where heavy metal can be found is the marine sediment. But the concentrations found are known to vary between locations. This also apply to the Limfjord, as was found in a previous project on the subject of heavy metal in the fjord. The scope of this project is to investigate the factors that govern these differences in concentration and find the correlations between the concentration of heavy metal and the local conditions. This was done with a primary focus on the content of organic matter, which was found to be strongly correlated to the concentrations of heavy metal. Depth and and placement of sample location that was studied and it was found to control organic matter and the stability of metal species was found to be inconsequential to the concentration of heavy metal.
