Assignment
1. Perform a Web search of carbon monoxide detectors or monitors. Some detectors simply beep when a certain concentration is exceeded. Others (may be called monitors) indicate the current CO concentration, while some devices record the data over time.
a. Identify two models of carbon monoxide detectors or monitors. These can be the simple type that beeps upon detecting a hazardous concentration or can actually indicate and record the concentration. Include the Websites.
b. Select a device that indicates the actual CO concentration. Present the specifications of the CO monitor in your own words. For instance, what is concentration range does it detect? What is the accuracy of the instrument? Does it run off batteries or a power cord? Does it store data?
c. Explain the principles of how the device operates.
d. What is the cost of the instrument?
Your response must be at least 250 words in length. All sources used must be referenced; paraphrased and quoted material must have accompanying citations.
2. Perform a Web search of nitrogen dioxide detectors (or monitors).
a. Identify two models of NO2 detectors. Include the Websites.
b. Present the specifications of one of the monitors in your own words. For instance, what concentration range does it detect? What is the accuracy of the instrument? Does it run off batteries or a power cord? Does it only store the data in the instrument or can it transmit the data wirelessly to a remote computer or data storage device?
c. Explain the principles of how the device operates.
d. What is the cost of the instrument?
Your response must be at least 250 words in length. All sources used must be referenced; paraphrased and quoted material must have accompanying citations.
3. Explain the following aspects of particulate matter sampling:
a. What is the impact of humidity on particulate matter measurements?
b. Describe direct mass measurement techniques for particulate matter sampling.
c. What are the advantages and disadvantages of tapered element oscillating microbalances, beta gauges, and light-scattering instruments?
Please provide exact page citations in your references.
Your response must be at least 250 words in length. You are required to use at least your textbook as source material for your response. All sources used, including the textbook, must be referenced; paraphrased and quoted material must have accompanying citations.
4. Present a plan for monitoring carbon monoxide in a city such as St. Louis, Missouri. Include monitor locations and why you chose those sites. Include comments about the accuracy of the required monitoring equipment, and take into account the averaging periods in the NAAQS. Please provide exact page citations in your references.
Your response must be at least 250 words in length. You are required to use at least your textbook as source material for your response. All sources used, including the textbook, must be referenced; paraphrased and quoted material must have accompanying citations.
