• Welcome to Unit 4. 
  • In this unit we will continue to evaluate indoor air pollution and its subsequent health effects. However, we will also consider a select group of diverse populations, specifically considering health effects of indoor air quality. Such an evaluation provides us with a unique opportunity to apply lessons learned in this environment to other environments from an epidemiological and systems in the 21 st century.In this unit you will be completing the following:1.

      Consider that an employee within a company-sponsored (OSHA required) medical monitoring program for your industry has just had an annual work physical and now reports to have pulmonary stress, hearing damage, and elevated blood lead (Pb) concentrations that were not previously reported on the employee’s pre-employment exam. As a result, the human resources manager has asked you to help determine what work-related variables may have contributed to the employee’s impacted health. What variables would you need to consider from within the work system, and what questions would you need to ask the worker to consider from within the worker’s area of residence? How would you attempt to delineate the air quality impacts from the employee’s work system and home?Your journal entry must be at least 200 words. No references or citations are necessary.

      As a continuation of our course project due in Unit VII (A Permit by Rule (PBR) Evaluation for Painting Operation Facility), complete the next section—Operational Air Emission Rates—of your proposal by following the instructions carefully, and then submit your continued draft of your evaluation document into Blackboard for grading.
    1. Closely read the required reading assignment from the textbook as well as the unit lesson in the study guide.
    2. Open your proposal draft from Unit III, and make any improvements to your draft using your professor’s feedback from the Unit III Mini Project.
    3. Open the Unit IV Study Guide, read the Unit IV Lesson, and then review the calculations demonstrated and explained regarding the operational air emission rates, 5-hour average period, and potential to emit (PTE) statistical model calculations for our scenario. Be sure to use the scenario data instead of the data used in the study guide examples.
    4. Make your Unit IV work the third level 1 heading, titled “Operational Air Emission Rates.” Describe the environmental, health, and safety (EHS) implications of VOCs in the work system while pulling from the textbook as well as any other relevant sources that are presented in the unit lesson in the study guide. In your description of the EHS implications of the system, be sure to discuss the natural and anthropomorphic variables causally related to adverse health effects on humans. Perform and present (not hand-written, but neatly typed) the calculations for the following in this section of your project: (a) calculating maximum hourly and annual emission rates, (b) reporting the emission rate averaged over a five-hour average period compared to the DEQ permit limits, and (c) reporting the potential to emit compared to the DEQ permit limits.
    5. In your abstract section (page 2 of the document), write one or two sentences that reflect your work for this unit. Remember that we are adding one sentence per unit to reflect our work as we go, with the final abstract length being about 8 to 10 sentences long.
    6. Your narrative and calculations for operational air emission rates must be presented in at least 200 words (minimum). You are required to use at least one outside source, which may be your textbook. All sources used, including the textbook, must be referenced; paraphrased and quoted material must have accompanying APA citations.

UNIT IV STUDY GUIDE Engineering Air Quality for Human Health Course Learning Outcomes for Unit IV Upon completion of this unit, students should be able to: 3. Assess health effects of air pollution. 3.1 Discuss the natural air pollution variables causally related to adverse health effects on humans. 3.2 Discuss the anthropogenic air pollution variables causally related to adverse health effects on humans. 3.3 Calculate operational air emission rates for a selected scenario. Course/Unit Learning Outcomes 3.1 3.2 3.3 Learning Activity Unit Lesson Chapter 5, pp. 155-197 Chapter 12, pp. 437-459 Unit IV Mini Project Unit Lesson Chapter 5, pp. 155-197 Chapter 12, pp. 437-459 Unit IV Mini Project Unit Lesson Chapter 5, pp. 155-197 Chapter 12, pp. 437-459 Unit IV Mini Project Reading Assignment Chapter 5: Health Effects, pp. 155–197 Chapter 12: Environmental Noise, pp. 437–459 Unit Lesson To date, we have discussed air pollution as being sourced either from natural or anthropogenic forces. In our reading for this unit, Godish, Davis, and Fu (2014) thoroughly explain the health effects of air pollution as well as tie together air pollution and noise pollution in a rather unique manner. This strategy of tying together noise pollution and air pollution deems consideration, perhaps even further than what is presented in our reading. Health Effects One of the interesting points that you may note as you progress through this program is that much of what is considered a pollutant to humans is actually already present in nature rather than synthesized. This includes some of what is mentioned in our unit reading, such as aerosols (ocean spray), hydrocarbons (petroleum oils), oxides of nitrogen (tropical forests), ozone (elevated atmospheres), and heavy metals (e.g., lead, mercury, cadmium, chromium) (Godish et al., 2014; Phalen & Phalen, 2013). A question could then be posed as to why or how natural phenomena, energy sources, tropospheric nitrogen compounds, and naturally occurring elements are available as environmental pollutants when in the presence of other ecological or human life. This is an important consideration, given that most of the time we may be asked to only engineer ambient air quality back to levels found to be at a state of climax in nature. MEE 6501, Advanced
