Part :
1. What is acid deposition, and what atmospheric constituents related to human activities are involved in acid deposition?
2. Define pH. What is the concentration of hydrogen ions in a solution with a pH of 5.6?
3. What observations led a large group of scientists in the 1950s and 1960s to become concerned about the problem of acid deposition?
4. What role do temperature inversions play in the development of photochemical smogs in urban areas?
5. What are the major natural and anthropogenic sources of VOCs and to the atmosphere?
6. Explain how the natural cycle of ozone in the troposphere is disrupted by anthropogenic emissions of VOCs and NOx.
7. What are some effects of tropospheric ozone accumulation on human health and ecosystems?
8. SO2 a major atmospheric pollutant in photochemical smog, has an average concentration of 0.2 ppbv (parts per billion by volume) in remote air. How many moles of SO2 are there in the background atmosphere?
