BIOMAGNIFICATION:
Brief Overview:
|
|
Examples of how to work the bioremdiation/biomagnification "MATH" questions:
1. Suppose an osprey eats 300 g of fish per day. The fish tissue consumed by the osprey has an average DDE concentration of 0.1µg/g. How much DDE is the osprey consuming in one day?
(300g fish/day)(0.1 µg DDE/g fish) = 30 µg DDE/day
2. Now suppose a bald eagle also eats 300 g of food per day. But, the bald eagle eats seal carcasses that have washed up on the beach. The seal had eaten fisheating fish with 1.0 µg/g DDE in their tissue. Much of the seal’s body is made of blubber (a fatty substance) and the DDE bioaccumulates in the seal. So, the seal has 2.0 µg/g DDE in its tissue. If the bald eagle eats 300 g of seal, how much DDE does the bald eagle consume in one day?
(300g seal/day)(2.0 µg DDE/g seal) = 600 µg DDE/day
3. Taking all factors into account, rank the following for likelihood of bioaccumulation: bald eagles, osprey, seals, and northern harriers.
1 – seals
2 - bald eagles (not only eat fish but scavenge on dead mammals and birds)
3 – osprey
4 – northern harriers
1. Suppose an osprey eats 300 g of fish per day. The fish tissue consumed by the osprey has an average DDE concentration of 0.1µg/g. How much DDE is the osprey consuming in one day?
(300g fish/day)(0.1 µg DDE/g fish) = 30 µg DDE/day

The seal had eaten fisheating fish with 1.0 µg/g DDE in their tissue. Much of the seal’s body is made of blubber (a fatty substance) and the DDE bioaccumulates in the seal.

TOXICOLOGY!!
Thursday videos: (including homework)

Post- Who recieves a higher dose activity questions:
1. Who were the two subjects? 2. What were they exposed to? 3. Describe the effect? 4. How was the does calculated? 5. What were their doses? |
Reflection Questions:
1. Is there a substance that is toxic at any dose? 2. Is there a substance that is safe at any dose? |
Questions:
1. Which variable(s) would you manipulate experimentally? 2. Which biological response(s) would you measure? 3. Compared to others, are these methods more or less practical? 4. Compared to others, are these methods more or less sensitive? |
“All substances are poisons: there is none which is not a poison. The right dose differentiates a poison and a remedy.”

BR:
1. What are some ways that humans and nature can clean-up water? 2. What is the difference between a drinking water treatment plant and waste water drinking plant? Would you drink water from a waste water treatment plant? |
Answers:
1. varies 2. Drinking water treatment plants purify water to make it drinkable (potable) for humans. Waste water treatment plants clean up water that humans have used enough so that it can be released back into the environment and not harm the plants and animals that rely on it. Cities and towns often draw water from rivers that include water from waste water treatment plants for their drinking supplies. They run the water through their drinking water treatment plants first. |
