Week 7 with instructions

Question 1

In the wake of September 11, 2001 and years to come, discuss the potential threats to the U.S. public health, and safety from a toxicological standpoint. Discuss how your life has changed since this event, if at all, and whether you feel that we are now more or less prepared to manage these potential toxicological threats

Question 2

Discuss and differentiate between sub chronic toxicity testing and chronic toxicity testing.

Question 3

Discuss how you perceive "risk." What toxicological risks do we experience in our daily lives, sometimes without recognition? What are some behaviors that can result in increased risk and how can we take steps to avoid them?

Each Question must be answered with at least 200 words in length. You are required to use at least your textbook as source material for your response. All sources used, including the textbook, must be referenced; paraphrased and quoted material must have accompanying citations. Case Study Background and Instructions: In recent years, honeybee colonies have been experiencing “Colony Collapse Disorder” (CCD). Given the key role of honeybees in pollinating our agricultural crops, it has become a serious issue. Many causes for the collapse of honeybee colonies are currently being investigated. The potential causes include viruses, parasites, urban sprawl, pesticides, and other environmental pollutants. Examine the phenomenon of CCD from a toxicological standpoint by researching three groups of chemicals that are being investigated as potential contributors to CCD: Antibiotics, miticides, and neonicotinoid pesticides. The assigned Case Study for this course deals with the phenomena of “Colony Collapse Disorder” in honeybee populations, and should include the following components:

 A brief introduction of the phenomenon.

 Background information on the groups of chemicals pertinent to the Case Study.

 Analysis of the key potential causes of the phenomena.

 Summary of the article's conclusions and your own opinions on the potential causes for the phenomena. Write a 4-5 page analysis (double spaced, 12 pt. type) of the potential causes listed above, and then discuss your opinion regarding which, if any, is the most likely cause. If you do not believe any of these chemicals are contributing to CCD, provide a brief discussion about what you believe to be the cause. Be sure to provide both in-text references as well as the full citations in APA format at the end of your analysis. Include a cover page and brief abstract for your analysis (these pages are not to be included in the total 4-5 page requirement). The Case Study assignment must follow APA style guidelines, therefore the APA rules for formatting, quoting, paraphrasing, citing, and listing of sources are to be followed.
