6.6. Particle Behavior and Respiratory Pathway

Try these first

1. 1.

   Define PM10 and PM2.5.

   Hint

   Focus on the size criteria for the two classifications.

2. 2.

   What is aerodynamic diameter?

   Hint

   Think about how particles move through a fluid like air.

3. 3.

   What size particles are included in PM10?

   • Less than 5 microns
   • Less than 10 microns
   • Less than 2.5 microns

   Hint

   Remember the size classification of PM.

4. 4.

   True or False: PM2.5 particles can reach deeper into the lungs than PM10.

   • True
   • False

   Hint

   Consider the health implications based on particle size.

5. 5.

   Analyze a case where a city experiences high PM2.5 levels. Discuss the potential health strategies to mitigate its effects on residents.

   Hint

   Consider how communities confront air quality challenges.

6. 6.

   Develop a research project proposal to study the effects of ultrafine particles on lung function. What factors would you include in your methodology?

   Hint

   Consider the measurements necessary for understanding smaller particles.
