Unit IV
Case Study
Background and
Instructions:
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”.
Link to: WHO's
Position Statement on DDT
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. What types of
toxicology data would you need to make this decision?
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?
Your Case Study assignment
should be three-four- pages in length. CSU requires that students use the APA
style
guidelines in writing
course papers. Therefore, the APA rules for formatting, quoting, paraphrasing,
citing, and listing of
sources are to be followed.
Unit VIII 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. Information resources can be gathered from the
journals and articles available in our
CSU Library Databases. 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.
