Part I. Save Smog City from Ozone: Emissions
(1 pt.) Based on your results from Data Tables 1 and 2 which emission source (industry, energy sources, cars and trucks, or consumer products) appears to have the largest influence on the AQI?
Answer: Cars and trucks
Population Influence
(2 pts.) How does AQI differ as population size changes? Why does this occur? (Hint: Look at the box labeled “Information” in the center lower portion of the simulator when Population is selected.)
Delegate your assignment to our experts and they will do the rest.
Answer: The AQI increases in value as the population increases. As the population increases, emissions increase from additional use of energy, cars/trucks, consumer products and industrial sources.
Part II Save Smog City from Ozone: Weather
(2 pt.) What happens to the AQI as temperature increases?
Answer: The AQI increases in value as the air quality rates from unhealthy to very unhealthy.
(2 pts.) What happens to AQI and ozone levels when the cloud cover increases? Why does this occur? (Hint: Look at the box labeled “Information” in the lower center portion of the simulator when Clouds/Sky Cover is selected.)
Answer: The AQI value decreases because clouds reduce sunlight and slow ozone formation. Particle pollution may form more quickly when there is more moisture or cloud droplets in the air hence increase in cloud cover speeds up formation of particle pollution.
(2 pts.) If you were responsible for maintaining air quality in Smog City what steps would you recommend taking to reduce ozone levels on hot, bright sunny days?
Answer: Create strict limitations on the solvent usage in factories, promote e-mobility, greening the city, vehicle ban in city centers, more spaces for bicycles and public transport .
Part III. Save Smog City from Particulate Pollution: Emissions
(2 pts.) What would have to be done in the real world to achieve a similar outcome for vehicles (cars, trucks and off road) in terms of the number of vehicles, energy efficiency, emissions controls, and fuel costs?
Answer: use of stricter testing and controls on vehicles will help reduce Nitrogen oxide emission from diesel passenger cars, vehicle ban in city centers and more use of bicycles and public transport.
(2 pts.) What happens to the AQI when all emission sources are set to position 1? Would this AQI ever be achievable in large cities given the all of the emissions that present in urban environments?
Answer: The AQI value will be 31 posing little or no risk of air pollution. This AQI can be achievable in large cities only when the strategies of reducing air pollution are followed by both industries and people living in the city.
(2 pts.) Why does a change in Population have such a strong influence on particulate emissions?
Answer: when there is a change in population, the total emission sources increases and thus affect the volatile organic compounds, Nitrogen oxides, and sulfur dioxide. These compounds react to form ground level ozone and particle pollution.
Part IV. Save Smog City from Particulate Pollution: Weather
(2 pts.) If you look closely at the graph of particulate levels, there is a change when the temperature decreases below 80 o F. Why would particulates increase when this occurs?
Answer: Lower temperatures enable gas emission to convert into particles. In temperature inversion, cold air is trapped near the ground by a layer of warm air. The warm air acts as a lid these substances down.
(2 pts.) Why do particulate levels in the atmosphere increase when there is an inversion?
Answer: During a temperature inversion, cold air is trapped near the ground by a layer of warm air. The warm air acts as a lid these substances down. At this time is when smoke cannot rise and carbon monoxide reaches an unhealthy level.
(1 pt.) What affect does wind have on the AQI when there is an inversion?
Answer: when there is an inversion, wind causes the AQI to decrease in value i.e. when it gets breezy or windy.
