Unit VI: Case Study  Animal use in toxicity testing has long been a controversial issue; however, there can be benefits. Read “The Use of Animals in Research,” which is an article that can be retrieved from http://www.toxicology.org/pubs/docs/air/AIR_Final.pdf.  Evaluate the current policies outlined in the Position Statement on page 5 of the article. Use the SOT Guiding Principles in the Use of Animals in Toxicology to guide you in your analysis. Feel free to use additional information and avenues of information, including the textbook, to critically analyze this policy.  In addition, answer the following questions:   How do toxicologists determine which exposures may cause adverse health effects?  How does the information apply to what you are learning in the course?  What were the objectives of this toxicity testing?  What were the endpoints of this toxicity testing?  Finally, include whether or not you agree with the Society of Toxicology's position on animal testing.  Your Case Study assignment should be three to four pages in length. Use APA style guidelines in writing this assignment, following APA rules for formatting, quoting, paraphrasing, citing, and referencing.  Information about accessing the Blackboard Grading Rubric for this assignment is provided below.
