1.12. Gravimetry Measurements

Try these first

1. 1.

   List two classifications of particulate matter.

   Hint

   Think about the sizes of the particles based on micrometer measurements.

2. 2.

   What does gravimetry measure?

   Hint

   Consider the 'grav' part of gravimetry.

3. 3.

   What is PM10?

   • Particles larger than 10 micrometers
   • Particles less than 10 micrometers
   • Particles that do not exist

   Hint

   Think about the definition of PM in relation to size.

4. 4.

   Gravimetry is used in PM measurement to determine what?

   • True
   • False

   Hint

   Revisit the core function of gravimetry.

5. 5.

   Considering the limitations of gravimetric measurement, propose alternative methods for evaluating PM concentrations.

   Hint

   Think about technology advancements in environmental monitoring.

6. 6.

   Calculate the PM concentration in a sample if 10 mg of PM is collected over a volume of 1000 liters.

   Hint

   Ensure your units are consistent when calculating.
