Unit 1 discussion

Introduce yourself to your classmates with your name, location, current employment, and future goals. In the event of a natural disaster such as Hurricane Matthew in 2016 or Hurricane Katrina in 2005, identify and explain which two specialized fields of toxicology would be most involved in assessing the health risks and environmental issues involved in the aftermath of the storms. What do you think their main role would be?

Unit 2 discussion

More states in the United States are legalizing the use of medicinal marijuana. Some states have laws that classify a person as being impaired to drive if an illegal substance or its metabolites are in the body. Marijuana, when it undergoes biotransformation, metabolizes into two different metabolites, Hydroxy-THC and Carboxy-THC. The first causes adverse effects (e.g., decreased motor coordination, lethargy, slurred speech, and dizziness) while the second, although it does not cause impairment, stays in the body for an extended period of time. Consider how marijuana's biotransformation may vary depending on the individual and the varying ability of marijuana's metabolites to cause impairment. Do you think that laws that prosecute regardless of the type of metabolite are justified to prosecute for a driving while intoxicated (DWI)? Why, or why not?

Unit 3 discussion

In 2013, the FDA set limits for arsenic in apple juice. In 2016, the FDA proposed a limit for arsenic in infant rice cereal. Consider the toxicological effects of arsenic on the body. Discuss what types of food are more likely to contain arsenic? What do you feel are the main concerns regarding digestion of these foods and the effects they could have on the body? Is the FDA sufficiently protecting the food supply in the United States from arsenic concerns? Why, or why not?

Unit 4 discussion

Carbon footprint is a term used to describe the impact an individual has on the release of carbon compounds, including carbon dioxide, into the environment. This carbon footprint is commonly produced by the burning of fossil fuels. With the burning of fossil fuels comes the release of many pollutants that cause health concerns, such as the release of particulate matter on the respiratory system. Reflect on individuals you know with respiratory, immune, or hepatic system concerns. How can the environmental toxicants affect their health? Whose responsibility do you think it should be to see that the carbon footprint from our community is reduced to minimize adverse health effects?

Unit 5 discussion

The skin is one of the largest organs of the body. It is also the body's first line of defense for protection against foreign agents and toxicants. Recall a time that you encountered an acute or chronic skin reaction from an environmental toxicant from the region in which you reside. What were the main symptoms of exposure? If you have never had such an experience, then discuss an environmental or industrial toxicant that is present in the region where you reside that may cause toxicity to the skin and the symptoms that might be expected. What do you think are the most effective safeguards against exposure to this toxicant?

Unit 6 discussion

We have examined toxicants that affect various systems of the body. What are your thoughts on biological warfare agents? Why do you think this type of toxicant is used? Do you think they are needed? What are some of the effects of these chemicals? With respect for your peers thoughts, provide your perspective on biological warfare.

Please include the name of the person or question to which you are replying in the subject line. For example, "Tom's response to Susan's comment."

Unit 7 discussion

Household cleaning products are some common solvents that you may be in contact with on a regular basis. Based on what you have learned about solvents, discuss what you feel is the most dangerous solvent that you commonly use. Do you think the cleaning product label properly warns you of the toxic effects of the solvent? What are some of the side effects of toxicity of the solvent? Why do you think this product is more toxic than other cleaning products that you come in contact with?

Please include the name of the person or question to which you are replying in the subject line. For example, "Tom's response to Susan's comment."

Unit 8 discussion

Identify a task that you would need to perform in your current career or future career, and explain how you would apply the knowledge you have learned in this course to succeed at performing the task in a real-word scenario.
