High PCN levels have been reported in abiotic samples from contaminated areas [4, 234, 235], Remarkably high PCN concentrations (61000ngg 1 dry weight) have been reported in sediment samples from Trenton located on the Detroit River (Michigan, USA) where several chemical manufacturing plants are located [236]. 

The sediments in nearshore areas of the Great Lakes are much more contaminated with PAHs than the open lake sediments. This is primarily because the coastal areas where one would sample contain the major ports where shipping and industry are concentrated. There are most certainly uncontaminated sediments in coastal areas, but for obvious reasons would not be sampled. The four highest reported sediment concentrations for 21 PA I Is are Duluth/Superior Harbor on Lake Superior, Milwaukee Harbor on Lake Michigan, the Detroit River between Lake St. Clair and Lake Erie and Hamilton Harbor on Lake Ontario (Fig. 7). The highest concentration reported was for Hamilton Harbor at 580 xg g 1, but that does not necessarily make it the most contaminated, as the range in concentrations were broad for all of the coastal areas.
