Gagandeep Rai Period 3/4 Criteria appearance pollutants assignment Multiple Choice 1. A pungent reddish cook gas often associated with photochemical smog. (C) NO2 2. A corrosive gas from anxious coal often associated with industrial smog. (d) SO2 3. A dangerous indoor billet pollutant. (A) CO 4. Emitted from diesel and burning give the axe. (E) PM10 5. All of the following atomic number 18 examples of elemental air pollutants except. (c) tropospheric ozone 6. The greatest emission of entropy dioxide comes from (C) Industrial growthes 7. The least come in of nitrogen oxide emissions comes from (A) on road vehicles 8. The accumulation of tropospheric ozone at night depends generally upon the atmospheric concentrations of (B) volatile organics 1. What are they? The six criteria air pollutants are sulfur dioxide, nitrogen oxides, carbon oxides,lead,particulate effect and tropospheric ozone. These six pollutants significantly threaten gentleman health, ecosystems and/or struct ures. 2. How is each produced? Sulfur dioxide is mostly produced from the burning of fossil fuels akin coal and oil. It can also be released during volcanic eruptions. Nitrogen oxides are produced from vehicles as well as stationary fossil fuel combustion. most is also released through lightning and forest fires.Carbon monoxide is formed by incomplete combustion of most matter. Vehicle exhaust and many other combustion process produce Carbon monoxide. It is also a indoor pollutant when exhaust systems on natural gas heaters misfunction. Carbon dioxide is produced from complete combustion of most matter such as biomass and fossil fuels. Particulate matter is released when fossil fuels and bio fuel is burned. Also it is released with activities that involve movement of dust or sand. Lead is released from grizzly paint, gasoline additive and combustion of fossil fuels.
