Question

precipitators are examples ofa technologies used to treat sick-building syndrome.b technologies used to counteract the effects of acid precipitation on aquatic ecosystems.c technologies used to capture radon gas.d technologies used to control pollution emissions.2.which type of building would most likely have poor indoor air quality?a one that is tightly sealed and air-conditionedb one that has not been repainted or recarpeted in several yearsc one in a cool climate with a good ventilation systemd one in an urban area where windows are often open3. what does voc stand for relating to air pollution?a volatile organic compoundb vocationalc virtual operations centerd vehicle out of commission4.which of the following would be a potential cause of sick-building syndrome?a acid precipitationb smogc fungid all of the above

Explanation:

1. Precipitators (like electrostatic precipitators) are devices that remove particulate pollutants from exhaust streams, so they control pollution emissions.
2. Tightly sealed, air-conditioned buildings limit fresh air exchange, trapping indoor pollutants and leading to poor air quality.
3. In air pollution contexts, VOC is the standard acronym for Volatile Organic Compound, which are common indoor/outdoor air pollutants.
4. Sick-building syndrome can be caused by multiple factors: acid precipitation can seep in and affect air quality, smog can enter or form indoors, and fungi (mold) from moisture are a well-documented indoor air irritant linked to the syndrome.

Answer:

1. D. technologies used to control pollution emissions.
2. A. one that is tightly sealed and air-conditioned
3. A. Volatile organic compound
4. D. all of the above
