Environmental Science Essay

Gagandeep Rai Period 3/4 Criteria air pollutants assignment sixfold Choice 1. A pungent reddishbrown burn out a good deal associated with photochemical smog. (C) NO2 2. A corrosive gas from burning coal oft associated with industrial smog. (d) SO2 3. A dangerous indoor air pollutant. (A) CO 4. Emitted from diesel and burning fuel. (E) PM10 5. All of the following are examples of primary air pollutants except. (c) tropospheric ozone 6. The greatest emission of sulfur dioxide comes from (C) Industrial processes 7. The least amount 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) erratic organics 1. What are they? The six criteria air pollutants are sulfur dioxide, nitrogen oxides, coulomb oxides,lead,particulate matter and tropospheric ozone. These six pollutants signifi set uptly threaten human health, ecosystems and/or structures. 2. How is severally produce d? Sulfur dioxide is mostly produced from the burning of fossil fuels like coal and oil. It can also be released during volcanic eruptions. Nitrogen oxides are produced from vehicles as rise as stationary fossil fuel combustion. Some is also released with lightning and forest fires. carbon copy monoxide is formed by incomplete combustion of most matter. fomite 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 bear on movement of dust or sand. Lead is released from old paint, gasoline elongate and combustion of fossil fuels.
