Q

VOCs + health implications

A

Released from household products like paint, cleaning supplies, and furniture. It can cause headaches, nausea, and long-term nervous system damage.

Q

Lead + health implications

A

Previously found in gasoline and paint; still present in some older homes. Causes neurological damage, particularly in children.

Q

Carbon monoxide + health implications

A

Produced by incomplete combustion (e.g., car exhaust, faulty heaters).
Prevents oxygen transport in the blood, leading to dizziness, unconsciousness, or death.

Q

Stratospheric vs Tropospheric Ozone

A

The stratosphere is good, and it absorbs harmful UV radiation. Troposphere is bad, part of smog which leads to respiratory issues

Q

Catalytic converters

A

Found in cars, they convert harmful gases (CO, NOₓ, hydrocarbons) into less harmful gases like CO₂ and N₂.

16
Q

Dry Scrubbers

A

Use chemicals or filters to trap pollutants before they leave a smokestack.

17
Q

Electrostatic precipitators

A

Use an electric charge to remove particulate matter from emissions.

18
Q

Natural sources of Co2

A

Volcanic eruptions, animal respiration, decomposition.

19
Q

Human causes sources of Co2

A

Burning fossil fuels, deforestation, cement production.

20
Q

Carbon dioxide units

A

Parts per million (ppm) in the atmosphere.

21
Q

Indoor air pollution (developing countries)

A

Biomass burning (wood, charcoal, animal dung) for cooking leads to high exposure to soot and carbon monoxide.

22
Q

Indoor air pollution (developed countries)

A

VOCs from cleaning products, radon gas from soil, mold, and poor ventilation contribute to indoor air pollution.

23
Q

Noise pollution sources

A

Traffic, airplanes, construction, industrial activities.

24
Q

Noise pollution health implications

A

Hearing loss due to prolonged exposure.
Increased stress and high blood pressure. Disrupts sleep and concentration.

25
Photochemical smog
Formed when NOₓ and VOCs react with sunlight, creating ozone and other harmful chemicals.
26
Thermal inversion
In an inversion, a layer of warm air traps pollutants near the ground, worsening air quality.
27
Cities impacted by smog
Los Angeles, Mexico City, Beijing (due to high vehicle emissions and frequent inversions).
28
Point source pollution
Pollution from a single, identifiable source (e.g., factory smokestacks, sewage discharge pipes).
29
10 micron vs 2.5 micron PM
10 micron or less cause upper respiratory concern, while 2.5 micron or less cause lower respiratory concern.
30
Wind patterns
0°–30°: East to West (Trade Winds) 30°–60°: West to East (Westerlies) 60°–90°: East to West (Polar Easterlies)
