6. Speciation Analysis and Source Apportionment

Try these first

1. 1.

   What is one method used to collect particulate matter?

   Hint

   Think about a common laboratory technique.

2. 2.

   Why do we need standard particles?

   Hint

   Remember how we compare sizes.

3. 3.

   What is gravimetric analysis primarily used for?

   • Measuring sound pollution
   • Measuring particulate matter
   • Measuring temperature

   Hint

   Think about what we collect and weigh in the lab.

4. 4.

   True or False: Aerodynamic diameter and optical diameter are always the same.

   • True
   • False

   Hint

   Consider how each diameter is defined.

5. 5.

   Design a study to analyze the impact of traffic on urban air quality. Define the measurements, sampling methods, and data analysis approach.

   Hint

   Consider where you would place samplers for accurate results.

6. 6.

   Discuss how advanced spectroscopic methods can improve the accuracy of source apportionment compared to traditional methods.

   Hint

   Think about the level of detail provided by different methods.
