Human contamination of the marine environment - Arthur Harbor and McMurdo Sound Antarctica
Article Abstract:
The rising levels of pollutants in Antarctica is proof of the widespread contamination of the environment by humans. Studies showed that an increase in polycyclic aromatic hydrocarbons, polychlorinated biphenyls, pesticides and heavy metals in the sediments and marine environment in McMurdo Sound and Arthur Harbor in Antarctica is the result of increased shipping activities and the improper disposal of wastes. This is proven by the high level of toxic substances in the tissues of marine organisms found in the regions.

Use of a simulation model to reconstruct PCB concentrations in prey of Lake Ontario lake trout
Article Abstract:
Polychlorinated biphenyl (PCB) concentration in muscle of the alewife, Alosa pseudoharengus, the principal prey of the Lake Ontario lake trout, Salvelinus namaycush, was four times higher in 1986 than during 1979-1985. The variability is attributed to fluctuations in PCB concentration in lake trout prey from year to year. Sensitivity analysis of PCB accumulation suggested that intraspecific variability is also present in PCB concentrations of lake trout prey.

How will decreased alewife growth rates and salmonid stocking affect sport fish PCB concentrations in Lake Ontario?
Article Abstract:
The influence of alewife growth rates, alewife polychlorinated biphenyl (PCB) concentrations and stocking scenarios on PCB concentrations in sport fish was investigated. It was suggested that a decline in alewife growth rates will lead to a corresponding decrease in sport fish growth rates and a rise in their PCB concentrations. As such, PCB concentrations in prey play a bigger role than salmonid growth rates in determining salmonid PCB concentrations.
