Gagandeep Rai Period 3/4 Criteria air pollutants assignment Multiple Choice 1. A pungent reddishbrown gas often associated with photochemical smog. (C) NO2 2. A corrosive gas from burning combust often associated with industrial smog. (d) SO2 3. A dangerous indoor air pollutant. (A) CO 4. Emitted from diesel and burning fuel. (E) PM10 5. every(prenominal) of the following ar examples of primary air pollutants except. (c) tropospheric ozone 6. The greatest emission of sulfur dioxide comes from (C) Industrial processes 7. The least measurement of nitrogen oxide emissions comes from (A) on road vehicles 8. The accumulation of tropospheric ozone at night depends mainly 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 subject field and tropospheric ozone. These six pollutants signifi give the axetly be human health, ecosystems and/or structures. 2. How i s each produced? Sulfur dioxide is closelyly produced from the burning of fogy fuels like coal and oil. It can also be released during volcanic eruptions. Nitrogen oxides are produced from vehicles as well as stationary fossil fuel combustion. Some 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 trend of dust or sand. Lead is released from old paint, gasoline additive and combustion of fossil fuels.
