1.7. Accumulative Sampling Techniques

Try these first

1. 1.

   What does vapor phase sampling aim to isolate?

   Hint

   Think about the key components in air analysis.

2. 2.

   Name one reason why grab sampling may be ineffective.

   Hint

   Consider the sampling location.

3. 3.

   What is the purpose of using filter paper in vapor phase sampling?

   • To absorb vapors
   • To collect PM
   • To store samples

   Hint

   Consider the first step in the sampling process.

4. 4.

   True or False: Grab sampling is suitable when concentrations are low.

   • True
   • False

   Hint

   Think about the conditions required for grab sampling.

5. 5.

   Design a monitoring plan for a factory's emissions. What types of sampling methods would you choose and why?

   Hint

   Consider emission concentrations and the types of analysis to be performed.

6. 6.

   Analyze how environmental conditions can affect the choice between grab and accumulative sampling.

   Hint

   Think of how external factors can alter measurement reliability.
