Small particulate matter can accumulate as an indoor air pollutant, and when inhaled, it can damage the heart and lungs. Identify ways the danger from particulate matter can be reduced in the home.
Select all that apply.
a. Change filters on heating and cooling systems according to manufacturer's directions
b. Use exhaust vents to move air outside while cooking
c. Use unvented stoves and fireplaces to prevent outdoor particulate matter from entering the home
a. Change filters on heating and cooling systems according to manufacturer's directions - Filters are effective at capturing particulates and removing them from the air.
b. Use exhaust vents to move air outside while cooking - Exhaust vents capture and release particulates outside of the home. They should be used to remove particulates that can accumulate when cooking on a stove.
Why not c? Unvented stoves and fireplaces can capture indoor particulate matter within the home. They should never be used in enclosed spaces.

Thermal inversion occurs when a layer of warm air forms over a layer of cool air. Which of the following are characteristics of thermal inversion?
Choose 2 answers:
a. Low-speed winds blow through the region.
b. In high-altitude areas, the inversion lasts longer.
c. The region experiences dense ground fog.
d. There is very dry air and no dew.
a. Low-speed winds blow through the region. - During thermal inversion, ground heat is released into the air by radiation. As a result, air rises at a steady rate, leading to calm winds.
c. The region experiences dense ground fog - Thermal inversions occur when the normal heat gradient is inverted. This causes the air near the ground to cool and form dense fog.
Colder air is less able to hold water vapor than warm air. This forces water vapor in the air around cooling objects to condense.

Which of the following atmospheric pollutants are likely to react with water, oxygen, and other chemicals to form acid rain?

b. nitrogen oxide (NO)
c. sulfur dioxide (SO2)

b. high rates of skin cancer in urban areas with sewage treatment plants
c. high rates of genetic deformities from additives in food supplies
d. high rates of obesity from exposure to waste from meatpacking
a. high rates of respiratory disease from power plant emissions

Scrubbers use liquids or dry, absorptive materials to reduce pollution at the source in many industrial processes.
Which of the following are the best ways to promote the use of scrubbers?
Select all that apply.
a. Increase awareness of the cost savings that scrubbers have on labor and clean up, which can enhance revenue
b. Change the kinds of scrubbers that are allowed to meet requirements
c. Move away from fuels that cause pollution in industrial processes
d. Enforce and expand restrictions on the amount of pollutants that can be released into the atmosphere
a. Increase awareness of the cost savings that scrubbers have on labor and clean up, which can enhance revenue - While scrubbers have high costs upfront, they often lead to less labor in cleaning and upkeep as less pollutants collect in the factories
d. Enforce and expand restrictions on the amount of pollutants that can be released into the atmosphere - Enforcement of the restrictions on the level of pollutants released by industrial plants would force industrial plants to install and upkeep scrubbers in order to continue running
Why not b and c?
b - Changing scrubbers would not necessarily lead to increased use of scrubbers
c - While moving away from these fuels would decrease pollution at the source, this would not promote the use of scrubbers

Draw a simple diagram showing how radon gets into homes and causes lung cancer.
radon from the soil seeps into homes through cracks/ windows
when breathed in, radon can undergo alpha decay and the alpha particles penetrate lung tissue, damage the DNA, and cause lung cancer

You just found out that your home has high levels of asbestos. In a few sentences, describe what you should do to protect yourself from the high levels of asbestos and why. Discuss the dangers of living in a home with asbestos.
Hire trained professionals with PPE to remove asbestos.
If asbestos fibers are inhaled, this can scar lung tissue and lead to lung cancer.

Most new cars and trucks are fitted with catalytic converters. Catalytic converters change harmful substances in cars exhaust gases into less harmful substances. Which gas products are most likely released when catalytic converter inputs are C3H6 + NO?
a. CO + H2 + Ce2O3
b. Ce2O3 + N2
c. CO2 + H2O + NO2
d. CO2 + H2O + N2
d. CO2 + H2O + N2
Carbon, nitrogen, hydrogen, and oxygen are elements present as inputs, so they are released by the converter as outputs. In this case, they are released as CO2, H2O, and N2, which are less harmful than C3H6 + NO.
