Employees on the second floor of a multi-story office building have been complaining about indoor air quality. Employees are convinced that there's "something in the air" because several employees report they only have symptoms at work, and the symptoms disappear as soon as they leave the office. A consultant proposing to be an indoor air quality expert provided a report with the following information about air samples collected on the second floor: 1200-1300 ppm carbon dioxide62-78% relative humidity.05 ppm formaldehyde (direct reading colorimetric tube)278 – 372 counts/m3 total airborne mold spores inside8,390 – 11,150 counts/m3 total airborne mold spores outside That's all the information you have. What additional information do you need to be able to evaluate the situation? Begin your discussion with your initial impressions and interpretation of the "consultant's" information. What conclusions, if any, can you make from the test results provided? Then, provide at least two…
