A critical review of the Benefits Analysis for the Great Lakes Initiative

Article Abstract:

The Environmental Protection Agency's (EPA) Benefits Analysis of its Great Lakes Water Quality Initiative (GLI) has overestimated the benefits of the program. A review of the Benefits Analysis shows that the value of components used by the EPA to estimate the reduction of cancer risks in humans used in the program were higher than likely, which led to the EPA estimate of $17,000 for every $1 mil invested. EPA estimates 17 to 34 cancers will be averted in the next 30 years in Michigan Lake. However, the review estimates the number of cancers averted by the program in the next six centuries to be only at one.

Synchronous response of hydrophobic chemicals in herring gull eggs from the Great Lakes

Article Abstract:

Herring gull eggs from the Great Lakes region were analyzed to investigate the cause of the synchronous behavior of hydrophobic chemicals in the area. It is suggested that large-scale weather patterns have a direct effect on hydrophobic chemical concentrations across the Great Lakes. Warm weather causes the proliferation of uncontaminated phytoplankton, which in turn provides less contaminated food for gulls during egg yolk formation.

Great Lakes herring gull egg PCB concentrations indicate approximate steady-state conditions

Article Abstract:

Three models were used to determine whether the level of polychlorine biphenyl (PCB) contamination in the Great Lakes basin are declining based on PCB concentrations in herring gull eggs from each of the five lakes. The results showed a decreasing pattern, indicating that the level of contamination in the Great Lakes continues to decline as previously reported.
