VOCs, Toxic metals

200
What 2 pollutants are needed tocreate ground-level ozone?


VOCs and nitrogen oxides

300

Blue crabs in Chesapeake Bay Maryland are dying, partly because of oxygen depletion in the polluted waters. What air pollutant is responsible for this?


Nitrogen oxides (nitrogen dioxide)

300
Although VOCs are emitted frommany sources, what is the primarynatural source of VOC emissions?


Plants/trees/forests

300
Which pollutant is least likely tobe found in high concentrationsin urban areas?


Ammonia

300
A colorless gas that is present where there are a lot of cars on the road, this poisonous pollutant may reduce oxygen flow to vital organs. What is it?


Carbon monoxide

300
Name the 2 toxic metals discovered on top of Mount Everest.


Arsenic and cadmium

400

This air pollutant is created when fuels such as wood or coal are not completely burned.


Carbon monoxide

400

How is “good” ozone formed?


Through the chemical interaction of the sun’s ultraviolet rays and oxygen in the stratosphere

400

How do temperature inversions affect carbon monoxide pollution?

CO concentrations are higher during cold months, when temperature inversions are more frequent, trapping CO near the Earth’s surface

400

Going jogging on a hot summer day can put you at risk of exposure to what pollutant?


Ozone

400

Name 2 pollutants. Here's the clue: the first one is found at higher levels in the winter and the other is found at higher levels in the summer.

1. Carbon monoxide 2. Ozone

500
