  • EXHIBIT A

  • EXHIBIT B

  • Suspected chemical contamination

  • The Cuyahoga River Feeds into Lake Erie

  • Male Fish are turning Female???

  • EXHIBIT D

  • EXHIBIT E

  • Whats wrong with this picture???

  • Major CategoriesInfectious agents (bacteria, parasites, viruses)

  • Oxygen demanding wastes (sewage, animal waste, plant debris)

  • Inorganic chemicals (acids, toxic metals)

  • Organic chemicals (Oil, gasoline, pesticides)

  • Inorganic plant nutrients (NO3-, PO4-, NH4+)

  • Sediment (soil, silt)

  • Radioactive materials (radon, uranium, cesium)Heat or Thermal (heat from power plants coal and nuclear)

  • Point Source: discharge pollutants at specific locations

  • Non-Point Source: scattered and diffuse; can not be traced to any single point.

  • What happens:to oxygen levels when oxygen-demanding wastes are added?

    to algae populations when phosphates and nitrates are added? And to the subsequent BOD and DO levels?

  • to the rate of photosynthesis if theres excess sediment?

    to the amount of DO if theres excess sediment?to the amount of DO when theres thermal pollution?

  • Eutrophication: Natural nutrient enrichment

  • Cultural Eutrophication: excessive inputs of nutrients due to human activities.

    What are NUTRIENTS????

  • Produce blooms of algae, cyanobacteria, or aquatic plantsInitially, produce Oxygen; however, massive die-offs and decomposition via bacteria sucks OUT all OxygenEcosystem suffocates!!

  • Animal wastesFertilizer run-off (agricultural and domestic)Sewage80-90% of raw sewage in developing countries dumped directly into lakes/streamsApprox. 85% of raw sewage from people around Mediterranean Sea dumped along the coast

  • 1.3 billion tons of animal waste produced in the U.S.Pollution strength up to 160 times greater than raw municipal waste.Animal wastes contribute to large oceanic dead zones, which extended to nearly 7,903 sq. miles in the Gulf of Mexico during Summer of 2007.

  • Dead ZonesOxygen Depleted ZonesAlso known as Hypoxic or Anoxic conditionsHABs: harmful algal bloomsRed, green, or brown TOXIC tides

  • A few of the worlds dead zones
