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 http://www.who.int/malaria/publications/atoz/who_htm_gmp_2011/en/
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.
To submit your completed Case Study, upload it using the "Case Study" link in Unit IV. Do not e-mail your paper directly
to your professor. By uploading through Blackboard, your university record will automatically be updated to indicate you
have submitted your paper, and it will be provided to your professor for grading.

Organization: it should have the following sections:

Introduction: Defines the purpose. Include the high points of the chemical nature of Lead (Pb) (atomic number, valence states, etc.). Also, what the abundance of Lead (Pb) in the Earth’s crust and in seawater.

Uses: Describe the uses of Lead (Pb). you may also find useful information from the USGS Minerals Information Team (http://minerals.usgs.gov/minerals/index.html). Find your Lead (Pb) under “Commodities”.

Environmental Guidelines: Summarize environmental guidelines for Lead (Pb) in drinking
water, soil (residential and industrial), stream sediment, and for acute and chronic toxicity to
aquatic organisms. Note: there may not be guidelines for Lead (Pb) in all media.

Pathways of Environmental Impact: Describe pathways that the element can affect
humans, and aquatic organisms. Are there key chemical transformations that affect the degree of
impact? What are they?

Case Study: Describe at least one case study that highlights the environmental toxicology of
Lead (Pb) to humans, aquatic organisms, or other wildlife. You must find an example in the scientific literature.

Conclusion: Summarize the major findings

References: cite all sources of information in APA, including in-text. websites like cdc, epa are acceptable, but sourses should be scientific journals, research data sources.
