$3.50 (200 Words) Unit II Journal
Take a few moments to reflect on what you know about the relationship between exposure to secondhand tobacco smoke and lung cancer. Now, think about Bradford Hill’s criteria for causation, and use it to evaluate the strength of the relationship between them. Based on Hill’s criteria, do you believe that the strength of the relationship is as strong as you have been led to believe? Why, or why not? Your journal entry must be at least 200 words. No references or citations are necessary.
Imagine that you are an industrial hygienist or a safety officer, and you have been asked to create a safety data sheet (SDS) for the employees within the manufacturing facility where you work. However, in this assignment, you will not actually create the SDS. You will just be collecting and studying specific data about the toxicity of certain chemicals that could be used to create it. Assume that the following chemicals/compounds are released during the manufacturing process:
benzene, vinyl chloride, asbestos, ammonia, and hydrogen chloride.
Choose one of these chemicals, and review the toxicology data for it. Create at least a two-page essay which outlines the following information about the chemical:
How can the route of exposure affect the toxicity of the chosen chemical/compound? How are the mechanisms of action and modes of action established surrounding how to deal with exposure to the chemical/compound? What are the effects that the chemical/compound chosen can have on the human body from the initial exposure to elimination?
Your essay should also discuss how the Bradford Hill criteria for causation is used to determine the strength of the toxicology data you reviewed. The essay should be at least two pages in length (not counting the title and reference pages) and should utilize proper APA citations and references.
