1.2. Impactor and Filter Design

Try these first

1. 1.

   What is the primary function of a PM sampler?

   Hint

   Think about what 'PM' stands for.

2. 2.

   What does PM10 refer to?

   Hint

   Consider size comparison to hair.

3. 3.

   What does PM2.5 signify?

   • Particles larger than 2.5 micrometers
   • Particles 2.5 micrometers or smaller
   • Particles 10 micrometers or larger

   Hint

   Consider the size in relation to PM10.

4. 4.

   True or False: PM10 measurements can potentially include PM2.5 measurements.

   • True
   • False

   Hint

   Remember the relationship between the two particle sizes.

5. 5.

   Evaluate how real-time monitoring technologies affect public policy decisions related to air quality improvement.

   Hint

   Think about how data might change perceptions and urgency in policymaking.

6. 6.

   Design a study using both a high-volume sampler and a cascade impactor. Discuss potential outcomes.

   Hint

   Consider what each tool provides and how they complement each other.
