Question

PART 1

(a) What is the major source of sulfur dioxide air pollution in the United Sates and offer three methods of reducing its emission
(b) List all air pollutants known to cause respiratory problems.

PART 2

In this part you will estimate your carbon footprint, or CO2 emissions, and test a series of conservation measures to reduce it by following the steps listed below:

Estimate your carbon footprint by going to the Environmental Protection Agency's website to use their household emission calculator (click here (Links to an external site.)Links to an external site. , if the calculator does not load after your click, then copy and paste the following link to your browser's address bar https://www.epa.gov/ghgemissions/household-carbon-footprint-calculator) to calculate your current emissions of carbon dioxide per year (this is Tab 1, "Current Emissions" of the calculator).

Then proceed to enter the following conservation measures to see what kind of reduction in your carbon footprint is possible (this is Tab 2, "Reduce Emissions" of the calculator):

Reduce your weekly driving miles by 20%
Replace your car with one having a 20% better gas mileage than your current car
Perform regular maintenance on your car
Lower heating thermostat by 2 degrees Fahrenheit on winter
Raise cooling thermostat by 2 degrees Fahrenheit in summer
Substitute 10% of your current electricity use with Green Power (i.e. power produced by wind, solar cells, etc.).
Replace 5 of your 75-watt incandescent light bulbs with 20-watt ENERGY STAR Links to an external site. lights
Replace old gas furnace or boiler with an ENERGY STAR Links to an external site. model

Once you finish step 2, the results will be displayed (this is Tab 3, "Estimated Savings" of the calculator). This includes your Current Emissions, and a list of your Actions and their Estimated Savings in both dollar and CO2 Emissions.

Copy and paste the entire results to a Microsoft Word (or your choice of word processor) document. This document should be submitted.

Study the results and submit a list of three conservation measures, that you have tested, that result in the top three highest reductions in your CO2 emissions.

Explanation / Answer

Problem.1

(a)

Sulfur dioxide is a gas. It is invisible and has a nasty, sharp smell. It reacts easily with other substances to form harmful compounds, such as sulfuric acid, sulfurous acid and sulfate particles.

About 99% of the sulfur dioxide in air comes from human sources. The main source of sulfur dioxide in the air is industrial activity that processes materials that contain sulfur, eg the generation of electricity from coal, oil or gas that contains sulfur. Some mineral ores also contain sulfur, and sulfur dioxide is released when they are processed. In addition, industrial activities that burn fossil fuels containing sulfur can be important sources of sulfur dioxide.

Sulfur dioxide is also present in motor vehicle emissions, as the result of fuel combustion. In the past, motor vehicle exhaust was an important, but not the main, source of sulfur dioxide in air. However, this is no longer the case.

In 2016, scientists published a global catalog of large sulfur dioxide sources as observed by OMI(Ozone monitoring Instrument.) Of the 92 major “hot spots” of sulfur dioxide in North America, 9 of them are volcanoes, 71 are power plants, 4 are smelters, and 8 are oil refineries. Note that some of the hot spots may represent multiple sources. The bulk of emissions in North America come from human activity; volcanoes represent about 30 percent of the total emissions.

What can be done to reduce it?

(b)

1) Particulate matter

2) Nitrogen Oxide

3) Ozone

4) Sulpher Dioxide
