Begin Q4: New seats; Homework Stamp; Continue Air Pollution

Hope you had a nice long weekend!

Today is the start of Quarter 4 - new seating chart...
I am allowing you the privilege of choosing your own seat for the remaining quarter. I trust you to wisely choose a seat where you will be productive. As always, as your teacher I reserve the right to choose a more appropriate seat for you if your selection is not in the best interest of our classroom community. ♡ Please limit each table to 4 students.

Announcements:
-AP Test Study Sessions:
 All tutorial A days leading up to test on 5/6: 2:23pm-4pm
-Fish tanks?
-Everyone will take a cumulative course final at the end of April/beginning of May (APES test-takers?)

Stamp for homework: 
34. Six Criteria Air Pollutants Chart

Continue Air Pollution notes in notebook...

To clarify: we are covering air pollutants according to where they are found in the atmosphere. The '6 Criteria Air Pollutants' are found in the first layer of the earth's atmosphere, the troposphere.

Distinguish primary vs. secondary pollutants from vocab list

NOx - nitrogen oxides, specifically nitric oxide & nitrogen dioxide

Additional known air pollutants:

VOC's 
- volatile organic compounds
-found in paints, aerosol sprays, dry-cleaning fluids, and industrial solvents
-examples: toluene (paint thinner)
                   xylene (paint, varnish, fingernail polish, adhesives)
                   formaldehyde (pressed-wood products, adhesives)                     benzene (natural and manufactured sources)
                   acetone (solvents, nail polish remover)
-concerns: causes respiratory irritation and damage; most are carcinogenic and cause liver, kidney, and central nervous system damage 
-levels of VOC's may be 1000 times higher indoors than outdoors


Ozone

Notes on ozone from EPA website

Ground-level (tropospheric) ozone is one of the major components of photochemical smog and a key health risk linked to breathing problems, asthma, reduced lung function and respiratory diseases. It is a secondary pollutant, meaning that it is not directly emitted. Instead, it is produced when carbon monoxide (CO), methane, or other volatile organic compounds (VOCs) are oxidized in the presence of nitrogen oxides (NOx) and sunlight.
