APES – Persistent Organic Pollutants

Persistent Organic Pollutants Assignment Due Mon, Apr 27th

Use the following to help  you with your research:

Persistent Organic Pollutants

EPA Perspective on Persistent Organic Pollutants

Persistent Organic Pollutants (POP)

  1. What are POP’s? Why are they an environmental and human health hazard?

For each POP, answer the following:

  1. What is the chemical structure? Formula?
  2. What kind of a chemical is it? (Chemical characteristics)
  3. Where and when is/was it produced and used?
  4. What was the purpose of using the chemical? Why is it still being used?
  5. Why is it still being used? (Production and Use)
  6. What are its effects on plants, people, and other animals? (Exposure and Effects)
    1. How long does it persist in the environment?
    2. Does it pose an acute and/or chronic hazard to humans? If it does, explain.
    3. Does it bioaccumulate?

Persistent Organic Pollutants (POP) and Organ Systems

Choose one of the Persistent Organic Pollutants and research its effects on human health by answering the following questions in paragraph form.

  1. How can humans be exposed to the chemical?
  2. How does it affect human health? Choose an organ system that this chemical attacks. What types of disease(s) does it cause? What are the acute and chronic effects of the disease(s)?
  3.  How does this chemical enter (routes of exposure) the organ system? What are the effects on that system? Which organs does it attack in the system you chose? What are the systemic and local effects?
  4. How likely is it to cause cellular damage? Mutations? Cancer? Explain how this occurs?
  5. Is there a medical test to show whether someone has been exposed to the chemical?
  6. What kinds of tests are being done to study the effects of the chemical?
  7. What kind of recommendations has the Federal Government made to protect human health from this chemical? (Make sure that you include information about the legislation involved)
  8. Discuss a case study where (a) this chemical created a hazardous situation and (b) How was this issue resolved?
  9. Citations of sources are required.

 

APES – Case Study on Air Pollution

Select a case study on air pollution:

http://www.umich.edu/~snre492/cases.html

Answer the following questions:

What was  the initial discovery in terms of air pollution?

What was the source of the pollution?

What lawsuits have been filed? What were the outcomes?

What health effects have been documented?

What do you think can be done to prevent similar problems?

Due Friday, April 24th. Please put your answer in the comment section for this post. I will be checking to see if you have submitted it.

STEM CELL RESEARCH POLICY PROJECT

 Due Fri, April 17th

Adapted from the Background, Activities and Critical Analysis

By Vicki Babcock , DeSoto High School, DeSoto, Missouri

Read the following supporting information for the different viewpoints about President Obama’s decision on stem cell research:

Mr. Obama’s decision: Obama Lifts Restrictions on Funding Human Stem Cell Research (http://www.pbs.org/newshour/updates/science/jan-june09/stemcell_03-09.html)

 The Washington Post: Obama Ends Ban on Stem Cell Research (http://www.washingtonpost.com/wp-dyn/content/article/2009/03/09/AR2009030901194.html

 The New York Times Magazine: Stem-cell Research and Kids’ Health (http://parenting.blogs.nytimes.com/2009/03/09/laurie-strongin-and-allen-gold/?hp)

  1. Read articles found at the links above.
  2. Your project should include the following in your choice of format (brochure, poster, etc):
    • Explain what stem cells are, where they are found, and how they may be used.
    • What is the function of each type of stem cell (embryonic, fetal, umbilical, and adult)?
    • What does it look like? Print out an illustration or draw a cell.
    • For what purpose have these stem cells been used in research?
    • How do scientists acquire and store these cells for research?
    • How is the source of the cells affected when the cells are acquired for research purposes?
    • Why might some consider this type of stem cell better for research use? Worse? Discuss the strengths and drawbacks.
    • Is there any existing legislation regulating the use of this type of stem cell?
    • Evaluate and defend or attack President Obama’s ruling on federal spending for stem cell research.
    • Choose a viewpoint. Three viewpoints could include:

                                                              i.      Full support of President Obama’s reversal of President Bush’s ban on funding for new lines of stem cells.

                                                            ii.      For the strict limits of Bush’s plan.

                                                          iii.      Against any use of embryonic stem cells, perhaps a bio-ethics group

  We will have an informal debate/class discussion about federal funding of stem cell research. More details to follow.
