Atmospheric loading of polycyclic aromatic hydrocarbons to Lake Michigan as recorded in the sediments
Article Abstract:
The transport of polycyclic aromatic hydrocarbons (PAHs) from the emissions from urban areas around Chicago, IL< and Gary, IN, to Lake Michigan was investigated by measuring the concentration of PAHs in the lake sediments. High concentrations of PAHs from the same location were found, particularly phenanthrene, benzo[b+k]fluoranthane, benzo[a]-pyrene and perylene. The accumulation of these compounds in lake sediments was attributed to historical coal use in IllINNis and extensive steel production in IllINNis and Gary, IN, as a result of in-lake integration processes.

Accumulation, inventory, and diagenesis of chlorinated hydrocarbons in Lake Ontario sediments
Article Abstract:
A study has been conducted to assess the accumulation and diagenesis of selected hydrophobic organic compounds (HOC) in five Lake Ontario sediments cores taken in 1990-1991 through lead dating. The lead profiles showed significant variability among cores, suggesting that particles are mixed and distributed evenly in sediments in the lake basins. They also indicated intraspecific variation in each basin.

Concentrations, accumulations, and inventories of toxaphene in sediments of the Great Lakes
Article Abstract:
Higher surface concentrations of the pesticide toxaphene was found in the northern part of Lake Michigan than in the southern part of the lake. Findings from some of the sediment cores examined at the Great Lakes indicate that toxaphene has slow degradation rate. The similar concentrations among all the Great Lakes suggest that the main bulk of toxaphene at the Great Lakes had come from the atmosphere.
