Think about how we physically handle PM in the lab.
Name one optical technique used for measuring PM.
Recall the methods involving light measurement.
What method primarily uses filters to collect and weigh particulate matter?
Think about physical evidence you can see.
True or False: Optical measurements provide mass data for PM.
Consider what type of data each method focuses on.
You are studying the effect of a new traffic policy on PM concentrations. Design a monitoring plan using both gravimetric and optical methods. Discuss potential sources of error and how to mitigate them.
Consider how varying methodologies may provide complementary insights.
