PHE 540 Principle Environment Health ( WATER)
Answer the following questions in complete sentences using Water as your topic.
Human Health Risk Assessment—Part 2 You will continue to evaluate the health risk of this environmental hazard by examining its dose-response and exposure risks. A. Hazard Identification. Please continue using the Human Health Risk Assessment Template as you complete
“Part A:
Hazard Identification.” Hazard identification is the process of identifying and selecting environmental agent(s) and health effects(s) for assessment. In this step, the main question addressed is this: Does this agent have adverse effects? To answer this question, please review the literature for information on the following: Explain relevant toxicokinetics, including the absorption/uptake, distribution, metabolism, and elimination processes. Provide a summary (one to two sentences) for each process. Discuss relevant toxicodynamics. Summarize the following: The effects on the human body (one to three sentences); o The mechanisms that impact human health (one to three sentences); o The insights into the possible effects (if known) (one to two sentences). Depict the Mode of Action by creating a concept map and inserting this image into the template. Your concept map will serve as a testable model of environmental insult. You may find it helpful to review Systems Thinking in the Healthcare Professions: A Guide for Educators and Clinicians (reference this resource as necessary) while constructing the concept map. In your concept map, illustrate the sequence of key events and processes, as follows: o Start with the interaction of an agent and a cell, o Proceed through to the operational and anatomical changes, and o Conclude with the resulting adverse effects on human health. B. Dose-Response. Please continue using the Human Health Risk Assessment Template as you complete “
Part B:
Dose-Response.” When public health professionals assess the dose-response, the relationship between exposure and effects is examined, answering the question: What are the health problems at different exposures? In the field, this assessment would involve significant data collection and processing. However, for this assignment, you will summarize the dose-response given the readily available information. Using the Human Health Risk Assessment Template, address the following: ● Adverse Effects (these might include physical, mental, socioeconomic, psychosocial, or other effects). Summarize the adverse effects at different dose levels (dose-responses). Please refer to the EPA’s website for further explanation on these components. C. Exposure. Please continue using the Human Health Risk Assessment Template as you complete “
Part C:
Exposure.” When public health professionals assess the exposure, the estimation or measurement of the magnitude, duration, and timing of human exposure to the agent of concern is the main focus. In this field, the m ain questions addressed by this type of assessment include: (1) How much of the pollutant are people exposed to during a specific time period? or (2) How many people are exposed? In the field, this assessment would involve significant data collection and processing. However, for this assignment, you will summarize the exposure given readily available information. Using the Human Health Risk Assessment Template, address the following: ● Exposure pathway and exposure route. Identify the chemical’s exposure pathway and route. Please refer to the EPA’s website for further explanation on these components.
