APES – Persistent Organic Pollutants

Persistent Organic Pollutants Assignment Due Mon, Apr 28th

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.

 

HT Biology – Timeline of DNA Discovery

Complete in-class on Wed, April 16th

Timeline of DNA Discovery

Read Sections 12.1 & 12.2

You will make a timeline o f DNA Discovery. Show how scientists came to understand the molecule known as DNA. The following people should be included in your time line:

  • Griffith
  • Avery
  • Hershey & Chase
  • Chargaff
  • Franklin
  • Watson & Crick

You will need to include the date, the scientists, what they discovered, describe their experiments, and indicate how their discovery aided in understanding the molecule DNA.

APES – Smog

Go to the following website: http://www.smogcity.com/

Go to the air pollution simulator tha shows how population , environmental factors, and land use contribute to air pollution.

Answer the following questions:

What are the two types of smog? How are they formed? (Use your textbook)

Does one factor (using the simulator) seem to affect smog formation more than others?

How do weather variables affect smog formation? How does population affect smog formation?

What can you do as an individual to reduce smog?

 

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?

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?
