4 cards from this section. Quick, good the night before a test.
What does PM stand for?
Think about what is in the air that could be measured.
Name one type of particulate matter measured by a cascade impactor.
These are classifications based on particle size.
What is a cascade impactor primarily used for?
Think about what we discussed regarding air pollution.
True or False: PM2.5 can have a diameter greater than PM10.
Recall how we categorized PM based on size.
A cascade impactor collects 500 micrograms of PM2.5 over a sampling period of 12 hours at a flow rate of 20 L/min. Calculate the concentration of PM2.5 in micrograms per cubic meter.
Convert hours to minutes and liters to cubic meters for accurate calculations.
Discuss the implications of using real-time monitoring technology in urban air quality management versus traditional sampling methods.
Consider how immediate data affects decision-making in pollution control.
