Three part discussion.

 4303: Part One: Describe how the Superfund or Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) or the Resource Conservation and Recovery Act (RCRA) law has affected you, your employer, or someone you know. Is there a Superfund remediation site near where you live or in your state? If you are overseas in the military (or for another reason), is there a hazardous waste site nearby? Please explain.

4302: Part Two: There are numerous models for assessing toxicity. Each model has pros and cons. The most highly debated model is the animal model; however, advances in technology are moving research toward utilizing in vitro testing, computer simulations, or other methods to analyze and predict toxic effects. Identify an assessment method that you believe could be the most promising technique outside of animal testing to effectively analyze toxicity of a chemical. Debate your choice with your peers.

4308: Part Three: Walking and working surfaces pose some of the greatest hazards to people. This is especially true in the occupational setting where the uneven surfaces can range from sand and gravel to an elevated working platform. After reading Chapter 27, look around your workplace or home at the various walking and working surfaces. Do you consider your workplace or home to be hazardous? Discuss why you consider them a hazard.
