4.1. OC and EC Analysis

Try these first

1. 1.

   What does OC stand for in PM analysis?

   Hint

   Think about carbon derived from plants or combustion.

2. 2.

   Name one measurement technique used for PM.

   Hint

   Consider methods that involve collecting particles.

3. 3.

   What does OC stand for?

   • Ozone Carbon
   • Organic Carbon
   • Optical Carbon

   Hint

   Think about carbon from living organisms.

4. 4.

   Elemental Carbon is primarily derived from what source?

   • True
   • False

   Hint

   Consider where smog and soot come from.

5. 5.

   Given the various techniques to measure PM, evaluate how you would design a study to compare the effectiveness of gravimetric vs. optical measurements in an urban environment.

   Hint

   Consider logistics in sampling and data analysis.

6. 6.

   Propose a method to standardize measurements for OC and EC across different laboratories. Discuss potential challenges in your approach.

   Hint

   Think about how differences in lab environments may impact accuracy.
