Description

Question 1 (part 1)

Identify an environmental toxicant in your area. Provide your opinion on the impact of this environmental toxicant and how big of a problem it is in your area. Is there a possibility of this environmental toxicant eventually having a large toxic effect on the population? Who do you think holds the responsibility of bringing cleanup of the toxicant to the forefront? Is it law makers, environmental protection agencies, or the residents of the affected area? Explain your response.

Your journal entry must be at least 200 words in length. No references or citations are necessary.

Question 1 (part 2)

This unit covers various ways that chemicals or toxicants can impact an individual. The impact that chemical exposure can cause ranges from localized effects on various organs and developmental or reproductive effects to cancer.

Consider the types of places that a safety inspector would visit for an inspection such as a manufacturing or processing plant, a construction site, or a pharmaceutical company. You may even consider the environment that a firefighter may encounter for this assignment. Then identify one chemical or toxicant that an individual may be exposed to in this type of workplace. Research the chemical or toxicant and discuss the following aspects in your scholarly activity response:

  • Identify the chemical and discuss the chemical properties. What level of exposure of this chemical is considered toxic? What duration of exposure can produce a toxic effect?
  • Identify the type of workplace where this chemical may be found and the use of the chemical in this environment.
  • Discuss how exposure of the chemical to the worker could occur. Include the route of exposure and what organ(s) or systems of the body could be affected.
  • Discuss the toxic effects produced from exposure to this chemical. Consider if it is a localized or systemic effect. Are the effects acute or chronic? Explain the symptoms and effects of the toxic exposure including the organs damaged and the type of damage that occurs. Is the chemical a carcinogen, allergenic, or something else?
  • Discuss how to prevent toxic exposure to the chemical and any known treatments available for toxicity from this chemical.

Your scholarly activity response should be at least two pages in length and utilize at least three credible sources. Adhere to APA Style when creating citations and references for this assignment. APA formatting, however, is not necessary.

Question 2 (Part 1)

A Saharan dust cloud traveled across the Atlantic Ocean in June of 2020. It was the densest dust cloud from the Sahara to reach the United States in approximately 50 years. Explain the health concerns that this event caused. If you were a safety professional, how would you have addressed health concerns in relation to this environmental event?

Your journal entry must be at least 200 words in length. No references or citations are necessary.

Question 2 (Part 2)

Utilizing the CSU Online library, identify three peer-reviewed research articles that review the toxic effects of a chemical substance on a specific organ or organ system. Create an annotated bibliography using these resources. The annotated bibliography should include 150-word descriptive and evaluative summaries following the full APA-formatted reference of each article listed. The summary of each article should be in your own words and not a reiteration of the article’s published abstract.

The following resource may assist you in completing this assignment. The CSU Online Library video How to Find Peer-Reviewed Resources provides assistance when searching the library. Closed captioning is available once you access the video.

Question 3 (Part 1)

There are numerous models for assessing toxicity. Each model has pros and cons. The most common 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. Reflect on how toxicity has been evaluated in the past and speculate on the most promising toxicity assessment methods for the future.

Your journal entry must be at least 200 words in length. No references or citations are necessary.

Question 3 (Part 2)

Many chemicals or drugs can elicit toxic effects. Assessment methods of these effects can vary based on the type of toxicity as discussed in Chapter 9 of the textbook. Identify one chemical or drug that elicits at least one of the toxic effects listed below:

  • irritation to the skin and eyes,
  • acute toxicity,
  • dose toxicity,
  • carcinogenicity,
  • genetic toxicity,
  • reproductive or developmental effects, or
  • skin and/or respiratory sensitivity.

Create a PowerPoint presentation that includes the following information:

  • your chosen chemical or drug and background information on the chemical or drug;
  • the designated use of the chemical or drug;
  • the symptoms of toxicity caused by the chemical or drug;
  • at least two methods of toxicity testing that would be utilized for the chemical or drug, which may be supported by the assigned textbook reading for this unit; and
  • a current event that occurred within the last 2 years pertaining to toxic exposure to a chemical and how toxicity was determined. If the assessment methods were not discussed, discuss how toxicity could be determined.

You can use the information from your textbook as well as information from other reliable sources; however, information from unmonitored websites, such as Wikipedia, is not acceptable. Access the CSU Online Library for additional resources. Be creative, and add photos, images, or other supplemental graphics to support your presentation.

Your presentation should include speaker notes to expand on the content of the slides. The length of the presentation should be least seven slides, not counting the title slide or reference slides. Ensure that you use images from the public domain or Creative Commons. You must use at least two references, one of which can be your textbook and one should come from the CSU Online Library. Adhere to APA Style when creating citations and references for this assignment. APA formatting, however, is not necessary.
