1qr. What are some of the main sources of air pollution? Get solution
1qt. Would you expect a fumigation-type smoke plume on a warm, sunny afternoon? Explain. Get solution
2qr. How do primary air pollutants differ from secondary air pollutants? Get solution
2qt. Give a few reasons why, in industrial areas, nighttime pollution levels might be higher than daytime levels. Get solution
3qr. List a few of the substances that fall under the category of particulate matter. Get solution
3qt. Explain this apparent paradox: High levels of tropospheric (ground-level) ozone are “bad” and we try to reduce them, whereas high levels of stratospheric ozone are “good” and we try to maintain them. Get solution
4qr. How does PM-10 particulate matter differ from that called PM-2.5? Which poses the greatest risk to human health? Get solution
4qt. A large industrial smokestack located within an urban area emits vast quantities of sulfur dioxide and nitrogen dioxide. Following criticism from local residents that emissions from the stack are contributing to poor air quality in the area, the management raises the height of the stack from 10 m (33 ft) to 100 m (330 ft). Will this increase in stack height change any of the existing air quality problems? Will it create any new problems? Explain. Get solution
5qr. How is particulate matter removed from the atmosphere? Get solution
5qt. If the sulfuric acid and nitric acid in rainwater are capable of adversely affecting soil, trees, and fish, why doesn’t this same acid adversely affect people when they walk in the rain? Get solution
6qr. Describe the primary sources and some of the health problems associated with each of the following pollutants: (a) carbon monoxide (CO) (b) sulfur dioxide (SO2) (c) volatile organic compounds (VOCs) (d) nitrogen oxides Get solution
6qt. Which do you feel is likely to be more acidic: acid rain or acid fog? Explain your reasoning. Get solution
7qr. How does London-type smog differ from Los Angeles-type smog? Get solution
7qt. Keep a log of the daily AQI readings in your area and note the pollutants listed in the index. Also, keep a record of the daily weather conditions, such as cloud cover, high temperature for the day, average wind direction and speed, etc. See if there is any relationship between these weather conditions and high AQI readings for certain pollutants. Get solution
8qr. What is photochemical smog? How does it form? What is the main component of photochemical smog? Get solution
9qr. Why is photochemical smog more prevalent during the summer and early fall than during the middle of winter? Get solution
10qr. Why is stratospheric ozone beneficial to life on earth, whereas tropospheric (ground-level) ozone is not? Get solution
11qr. If most of the ozone in the stratosphere were destroyed, what possible effects might this have on the earth’s inhabitants? Get solution
12qr. Get solution
13qr. (a) On the AQI scale, when is a pollutant considered unhealthful? (b) On the AQI scale, how would air be described if it had an AQI value of 250 for ozone? (c) What would be the general health effects with an AQI value of 250 for ozone? What precautions should a person take with this value? Get solution
14qr. Why is a light wind, rather than a strong wind, more conducive to high concentrations of air pollution? Get solution
15qr. How does atmospheric stability influence the accumulation of air pollutants near the surface? Get solution
16qr. Why is it that polluted air and inversions seem to go hand in hand? Get solution
17qr. Major air pollution episodes are mainly associated with radiation inversions or subsidence inversions. Explain why. Get solution
18qr. Give several reasons why taller smokestacks are better than shorter ones at improving the air quality in their immediate area. Get solution
19qr. How does the mixing depth normally change during the course of a day? As the mixing depth changes, how does it affect the concentration of pollution near the surface? Get solution
20qr. For least-polluting conditions, what would be the best time of day for a farmer to burn agricultural debris? Explain your reasoning. Get solution
21qr. Explain why most severe episodes of air pollution are associated with slow moving or stagnant high pressure areas. Get solution
22qr. How does topography influence the concentration of pollutants in cities such as Los Angeles and Denver? In mountainous terrain? Get solution
23qr. List the factors that can lead to a major buildup of atmospheric pollution. Get solution
24qr. What is an urban heat island? Is it more strongly developed at night or during the day? Explain. Get solution
25qr. What causes the “country breeze”? Why is it usually more developed at night than during the day? Would it be more easily developed in summer or winter? Explain. Get solution
26qr. How can pollution play a role in influencing the precipitation downwind of certain large industrial complexes? Get solution
27qr. What is acid deposition? Why is acid deposition considered a serious problem in many regions of the world? How does precipitation become acidic? Get solution
