Create a 15- to 20-slide Microsoft® PowerPoint® presentation discussing the nutritional needs during a person’s different life stages (childhood, adulthood, pregnancy, lactation, and such). Include the following in your presentation:
• Define nutrient, energy, and fluid needs during each life stage.
• Describe nutrients of concern or special concerns during each life stage.
• Identify physical activity recommendations during each life stage.
• Discuss the following topics for the specified stages of life:
• Pregnancy – weight gain recommendations
• Lactation – benefits of breastfeeding
• Infancy – growth rate
• Childhood – helping kids develop healthy eating habits and bodies
• Adolescence – helping teens meet nutrient needs
• Adulthood – aging and factors that affect it

How do toxicologists determine which exposures may cause adverse health effects?

/in /by

1. 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 fromhttp://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.

What steps are in place to eliminate the pollutant or to mitigate harm from the pollutant?

/in /by

Pollutants can harm ecosystem function and may also harm human health.
You will write an 3 page body APA-style research paper about pollutants, their impacts, and mitigation of harmful effects. Include the following:
• Select 1 example of an environmental pollutant from the following list:
o Acid precipitation/ Acid rain
o Smog
o DDT pesticide use
o Eutrophication
• Answer the following questions about the pollution problem that you chose:
o Describe the pollutant chosen and the source of the pollutants. Include both natural and human sources, as applicable.
 Is this a point-source pollutant or nonpoint-source pollutant? Explain.
o What are the harmful impacts of the pollution?
 Describe impacts to both humans and to ecosystem structure and function.
o What steps are in place to eliminate the pollutant or to mitigate harm from the pollutant?
 Describe examples of laws or regulations that apply to the pollution and its sources.
 Also, describe educational programs, technology, or other initiatives that are used to help control the pollution.
o Have the programs, best management practices, or regulations been effective in resolving harm from the pollutant?

Unit IV Case Study

Analysis of an Air-Sampling Report

See attachement to view a PDF of a typical sampling report.

Compose a two- to three-page analysis that addresses the following questions:

1. What is the purpose of the exposure assessment?
2. Why was the exposure assessment conducted?
3. What type of sampling (personal or area) was conducted, and why?
4. What are the chemicals that were sampled, and what are their hazards?
5. What are the most likely routes of exposure given the nature of the business?
6. Describe the sampling equipment and methods used to collect the sample.
7. Provide an overview of the results, including an explanation of the “additive formula,” and discuss them in relation to the applicable exposure limit.
8. Were there any off-normal or unplanned incidents relative to sample collection?
9. Provide a summary of the recommendations made by Sam “IH” Sampler.
10. Comment on the thoroughness of the study. Did you feel that the exposure assessment was comprehensive? If not, what additional information would you provide?
11. Comment on who the target audience would be for this report. If you were the plant director of ACME Printing, would you be comfortable with sharing this with an auditor from the Occupational Safety and Health Administration (OSHA)? Do you have any concerns related to sharing this with your employees?
