A primary pollutant that has undergone a transformation in the presence of sunlight, water, oxygen, or other compounds.
secondary pollutant
NO2, VOCs, O2, and sunlight create this phenomenon.
photochemical smog
This pollutant is released from fossil fuel / biomass combustion and volcanoes, plus is measured in micrometers.
Particulate Matter (PM)
This carcinogen has great insulating properties and can be found in old houses
Asbestos
Disrupted migration patterns and hunting abilities are an effect of this pollutant
Noise Pollution
Before the Clean Air Act, what was a common gasoline additive that was phased out by the EPA in 1974
Lead
In this layer of the atmosphere is Ozone (O3) harmful.
troposphere
A lightning strike can create these pollutants
***Sunny Days TRIPLE***

NO2 or O3
Vapor recovery fuel nozzles reduce this pollutant
VOCs
This type of pollution leads to acidification and degradation of building materials and both aquatic and terrestrial habitats.
acid rain
What is the Clean Air Act? What were the Pollutants it limited?
identified 6 criteria air pollutants that the EPA is required to set acceptable limits for, monitor, and enforce
SOx, NOx, CO, PM, O3 & Lead
What is Thermal Inversion?
a meteorological phenomenon that develops when cool air is trapped at the ground under a layer of warm air
Aerobic Decomposition of organic matter by bacteria & decomposers in the presence of oxygen releases what gas?
CO2
This system in cars reduces NOx, CO, and hydrocarbons using a honeycomb device.
catalytic converter
This natural base, often found in bedrock, can be added to soils or water to "buffer" or neutralize the effects of acid rain
Limestone (Calcium Carbonate)
What is an example of a Primary Air Pollutant that we learned?
**DAILY DOUBLE***

NOx, CO, VOCs, SO2, PM
This term explains why urban areas tend to have higher surface & air temperature than surrounding suburban and rural areas
Urban Heat Island Effect
Anaerobic Decomposition is the decomposition of organic matter by bacteria & decomposers in low or oxygen-free conditions releases what gas?
CH4 (methane)
These air pollution control devices use calcium-based solutions to knock SO2 and NO2 out of exhaust.
wet and dry scrubbers
These two primary pollutants are the main causes of most acid precipitation
Nitrogen Oxides (NOx) and Sulfur Dioxide (SO2)
What is an example of a Secondary Air Pollutant?
Tropospheric O3 (Ozone)
Sulfuric acid (H2SO4) & sulfate (SO42-)
Nitric acid (HNO3) & nitrate (NO3-)
What are THREE effects of Thermal Inversion?
- Respiratory irritation: asthma flare-ups leading to hospitalization, worsened COPD, emphysema
- Decreased tourism revenue
- Decreased photosynthetic rate
Air Pollutants impact the economy by:
What is increasing health care, infrastructure repairs etc
Coal power plants use this to ionize PMs and remove pollutants
electrostatic precipitator
When NOx and SO2 react with oxygen and water in the atmosphere, they form these two specific acids
Nitric Acid (HNO3) and Sulfuric Acid (H2SO4)
