1.8. Ground Level Concentration

Try these first

1. 1.

   What is ground level concentration?

   Hint

   Think about the air quality measurements.

2. 2.

   Define emission factor.

   Hint

   Consider it a rate.

3. 3.

   What does ground level concentration refer to?

   • Quality of air at higher altitudes
   • Pollution levels at ground level
   • Measurement of greenhouse gases

   Hint

   Think about where people breathe.

4. 4.

   Emission factors are important for:

   • True
   • False

   Hint

   Why is consistency important in measuring emissions?

5. 5.

   Consider an industrial plant emits 100 kilograms of a pollutant per hour. If the emission factor for similar plants is noted as 2 kg pollutant/unit operation, how many operational units is the plant running?

   Hint

   Dividing total emissions by the emission factor will give you the number of units.

6. 6.

   How would the presence of an unexpected leak in a pipeline affect the ground level concentration calculations for nearby communities?

   Hint

   Consider what makes a measurement valid.
