Select one of the six criteria air pollutants and describe how you would prevent human exposure. This can take a variety of methods including source control, exposure control, engineered capture systems.
Solution
Six criteria air pollutants are ground level ozone, particulate matter, sulphur dioxide, carbon monoxide, nitrogen dioxide and lead.
We can control the source of SO2 by using low sulphur fuels such as natural gases.
Fluid bed combustion decreases air emissions of SO2. A line or dolomite bed in the combustion chamber absorb the SO2 generated.
Sorbent injection method uses addition of alkali to the coal combustion gas to react with SO2. Lime and variants of lime are used. It reduces 30-60% SO2 emissions.
