1 Pollution in the Great Lakes A Study of how pollution affects wildlife in the Great Lakes Amy Latham, Amanda Tsang, Eric Wright Environ 110, Section 5 Environ 110, Section 5

2 Introduction Earlier beliefs that water could dissolve chemicals and other wastes led to the degradation of the Great Lakes ecosystemEarlier beliefs that water could dissolve chemicals and other wastes led to the degradation of the Great Lakes ecosystem Pollution has negative effects on the flora and fauna of the Great Lakes ecosystem.Pollution has negative effects on the flora and fauna of the Great Lakes ecosystem. -reducing water quality, contaminating soils, and harming the lake wildlife and surrounding region

3 To demonstrate a direct effect that pollution has on the Great Lakes ecosystem, we analyzed data from four pollutants and the biomass of trout residing in Lake Huron. To demonstrate a direct effect that pollution has on the Great Lakes ecosystem, we analyzed data from four pollutants and the biomass of trout residing in Lake Huron.

4 Background: Sources of Pollution Point-source pollution Point-source pollution - direct source of pollution (e.g. a pipe) - mercury, sewage, and fecal matter Non point-source pollution Non point-source pollution - non-specific locations (e.g. air-bound pollution, industrial runoff) - fertilizers and pesticides

5 Background: Effects of Pollution Pollutants move up food chains Pollutants move up food chains Reduce fish stocks Reduce fish stocks Decrease water quality Decrease water quality Spreads diseases Spreads diseases

6 Methods Researched material through Mirlyn website Researched material through Mirlyn website Used Microsoft Excel to create graphs to analyze the relation between pollutants and the Great Lakes. Used Microsoft Excel to create graphs to analyze the relation between pollutants and the Great Lakes. We used specific data from the biomass of Lake Huron Trout and the concentration of four prominent chemicals in Lake Huron We used specific data from the biomass of Lake Huron Trout and the concentration of four prominent chemicals in Lake Huron

7 Results and Discussion Pollutants concentration found in tissue of Lake Huron trout. PCB and toxaphene have highest concentration.

8 Results and Discussion Relationship between the four pollutants and trout biomass (kg).

9 Results and Discussion Specific correlation between trout biomass and PCB concentration

10 Results and Discussion Specific correlation between trout biomass and toxaphene concentration.

11 Implications Restricts wildlife and fish growth Restricts wildlife and fish growth Wildlife deformities and spread of diseases Wildlife deformities and spread of diseases Degrades natural communities Degrades natural communities Limits wildlife consumption Limits wildlife consumption Closes beaches and hinders other recreational activities Closes beaches and hinders other recreational activities

12 Solutions Clean Water Act, 1972 Clean Water Act, 1972 Great Lakes Water Quality Agreement, 1972 Great Lakes Water Quality Agreement, 1972 State of the Lakes Ecosystem conference State of the Lakes Ecosystem conference Clean Michigan Initiative, 1998 Clean Michigan Initiative, 1998

13 Conclusion Great Lakes are an important source of freshwater and their contamination affects both the wildlife surrounding the region and those who utilize its vast resources Great Lakes are an important source of freshwater and their contamination affects both the wildlife surrounding the region and those who utilize its vast resources Though measures have been taken, more are needed to protect the valuable resources of the Great Lakes Though measures have been taken, more are needed to protect the valuable resources of the Great Lakes
