   Hint

   Think about why we need to know where pollution comes from.

2. 2.

   What does PM10 stand for?

   Hint

   It refers to the size of the particles.

3. 3.

   What does PM2.5 refer to?

   • Particulate matter >= 2.5 micrometers
   • Particulate matter < 2.5 micrometers
   • Particulate matter = 2.5 micrometers

   Hint

   Focus on the '<' symbol when recalling sizes.

4. 4.

   Are nanoparticles often derived from vehicle emissions?

   • True
   • False

   Hint

   Think about where many small particles come from in a city.

   Hint

   Reflect on how voltage affects particle selection.

6. 6.

   Evaluate the impact of ultrafine particles on public health in urban areas. What data would you need to analyze?

   Hint

   Think about sources of data and health studies.
