POLLUTION

 Pollution  Habitat  Ecosystem  Wetland  Sediment  Food chain  Benthos/Benthic  Bioaccumulation

What is pollution? What does pollution look like? Smell like? Taste like? What are examples of pollution near your school? What does pollution do to an animal’s habitat?

 The mud at the bottom of a body of water  The foundation of the ecosystem  Home for tiny critters and plants (benthos)

 Community of tiny critters and plants that live in the sediment

Polluted Sediment = Polluted Benthos Pollution

 When a fish eats polluted benthic organisms, that pollution goes into the fish and can remain a long time. If the fish eats more polluted benthic organisms, the pollution inside the fish increases. This is bioaccumulation.  Bioaccumulation demonstration

Polluted Sediment = Polluted Benthos Pollution

 GreatLakesMud.org has a page dedicated to the cleanup of each Area of Concern. GreatLakesMud.org  On each Area of Concern page, look for 1) the number of cubic yards being remediated, 2) the number of acres to be restored, and 3) the cost.  Use that information on the next slide. IndianaMinnesota Grand Calumet RiverSt. Louis River’s US Steel Site MichiganWisconsin Detroit River’s Upper Trenton Channel Milwaukee River’s Lincoln Park Lower Rouge River Muskegon Lake’s Zephyr Site Check GreatLakesMud.org for more…

 How much is getting cleaned up?  Sediment Volume: _______ cubic yards  Divide that number by 15.4, that’s how many dump trucks you will need.  ______ acres of aquatic habitat  How much does it cost?  For every $1 million, you can:  Buy two Lamborghini Aventadors  Meet for coffee with Apple CEO, Tim Cook, twice  Buy ONE bottle of “Gout de Diamants’ champagne.

 You’ve talked about how to tell if something is polluted.  Today we’ll do an experiment to help understand how scientists study pollution.

 Another thing scientists think about is how the pollution affects an ecosystem.  Sometimes it affects different parts of the food chain in different ways.  If we cleaned up the polluted sediment for the plants – how much would we need to clean up? How about for the falcon?

 We will break into teams.  Each team will get an ‘ecosystem’ to experiment with and will be given supplies.  Each team will use their supplies to make their experimental ecosystems polluted (for our experiment, we are using safe materials for our pollution).  Then the teams will trade ecosystems. The teams will have to try and determine what the other team’s ecosystem is polluted with.
