The use of DDT has been banned in the United States because of environmental damage and human health concerns. However, in malaria-plagued countries such as Africa, the World Health Organization approves the use of DDT for indoor residual house spraying.
Read the following WHO's Position Statement, “The use of DDT in malaria vector control”.

Take the position that you work for the World Health Organization, and have been tasked with re-evaluating the current policies outlined in their Position Statement. Using the instructions to guide you in your analysis, answer the following questions. Feel free to use additional information and avenues of information to critically analyze this policy.
1. How would you use a risk versus benefit assessment, and what other types of toxicology data would you need to make this decision? Refer to Chapter 12.
2. Use the four phases of the disposition of a toxic compound to assess the toxicity of DDT.
3. What types of exposure and response are associated with DDT?
4. Should the WHO continue to approve the use of DDT to combat malaria?
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.
