Air Pollution worksheet MD

Suppose you have an 8-hour ozone value of 0.088 ppm, and a PM2.5 value of 35.7 ug/m3. The AQI value is Blank 1 and the responsible pollutant is Blank 2. According to the AQI scale, this falls under the category Blank 3. Note: for the pollutant, choose between ozone and PM2.5 These Breakpoints.. .equal this AQI .and this category Air Quality Index Levels of Health Concern Numerical Value O3 PM25 PM10 CO SO2 NO2 AQI (ppm) 1-hour (H8/m) (H8/m²) (ppm) 8-hour (ppm) (ppb) (ppb) 8-hour 24-hour 24-hour 1-hour 1-hour Good 0 to 50 0.0 - 4.4 0- 53 0- 50 0.000 - 0.054 0.0- 12.0 0- 54 0- 35 Good Moderate 51 to 100 55 - 154 54 - 100 0.055 - 0.070 12.1 - 4.5 - 9.4 36 - 75 51 - 100 Moderate 35.4 Unhealthy for Sensitive Groups 101 to 150 0.125 - 155 - 254 9.5 - 12.4 76 - 185 101 - 360 101 - 150 Unhealthy for Sensitive Groups 0.071 - 35.5 - 0.085 0.164 55.4 0.086 - 0.165 - 255 - 354 361 -649 151 - 200 Unhealthy 151 to 200 (55.5 - 150.4) (186 - 304)* 12.5 - Unhealthy 0.105 0.204 15.4 Very Unhealthy 201…

Without naturally occurring greenhouse gases, Earth's average global temperature would be near 0°F (or -18°C) instead of the actual value of 59°F (15°C). How do atmospheric greenhouse gases warm Earth? Do not use the word “trapped” in your answer

If gasoline produces only carbon dioxide and water when it burns completely, why is automobile exhaust a source of air pollution? List the pollutants formed and briefly describe their impact.

4. Photochemical smog is a type of air pollution in the troposphere of our planet produced when sunlight acts upon motor vehicle exhaust gases to form harmful substances such as ozone (O3). For example, nitrogen dioxide (NO2) reacts with atmospheric oxygen (O2) in the presence of light to produce ozone (O3) and nitrogen monoxide (NO).

Suppose you have an 8-hour ozone value of 0.078 ppm, a PM2.5 value of 35.9 ug/m3 , and a CO value of 8.4 ppm. The AQI value is Blank 1 and the responsible pollutant is Blank 2. According to the AQI scale, this falls under the category Blank 3

13 The air that we breathe is actually a mixture of mostly the following gases- 78% N2, 21% O2, and (<1.0%) CO2 and H₂O and constitute about 99% of the air mixture on a poor air quality day. That remaining, approximate 1% of the air is associated with trace amounts of air and particle pollutants that can affect air quality, especially on hot, summer days. Groups that can be affected by poor air quality include those who have asthma, heart disease, and chronic obstructive pulmonary disease (COPD). If the total air pressure is 1.0 atm, what would be the partial pressure (atm) of O2 on a poor air quality day? atm. 480 words IX English (United States) (5 points) Focus F E

#3, Answer is already there. Just need to learn how to do the work.

The following are Federal Air Quality Standards for the US CO: 35ppm (1-hour) NO2: 0.053ppm (Actually NOx but please use NO2 to calculate) 03: 0.075 ppm SO2: 75ppb (1-hour) a) Calculate the air concentrations in ug/m³ corresponding to the standards. Detail your calculations. b) What would be the mass concentrations on Mars if the little green men would apply the same standards in terms of mixing ratio. Explain your assumptions.

Some pollutants are difficult to break down and therefore accumulate in the environment. These are termed chronic pollutants. non-persistent pollutants. persistent pollutants. chemical indicators.

2.) It’s a bad day in the lab!  Two students are doing experiments.  Each is 20 feet away from the professor.  At the same time, each of them lets the same amount of a smelly gas into the room.  One of them releases ammonia, NH3, and the other releases SO2.  NH3 has a pungent odor, and SO2 smells like rotten eggs.  The professor has no idea that this has happened, until she smell the first gas.  Which chemical will the professor smell first?   (NH3 or SO2)                                .  If the professor starts to smell the first gas 42. seconds after the gas is released, how long will it take her to smell the second gas?       sec. * Note: It is unsafe practice to work with these chemicals in an open lab.

MULTIPLE CHOICE Question 18 Which scenario best describes the long-term health effect of air pollution exposure? A woman exposed to toxic chemicals in ground-level air pollution experiences a change in DNA, resulting in lung cancer. B. A man exposed to toxic chemicals in ground-level air pollution experiences extreme eye irritation that clouds his vision. A man exposed to toxic chemicals in ground-level air pollution experiences a cough. D. A woman exposed to toxic chemicals in ground-level air pollution experiences an ex- treme headache.

Octane, C8H18, can be used as a representative compound for gasoline.a. Is the combustion of octane a source or sink of a GHG? Explain.b. Write and balance the chemical equation for the combustion of octanec. Calculate the mass of carbon dioxide produced from the completecombustion of 1.0 gallon of gasoline, assuming the fuel is only octane.• Things to think about: How will you start this problem? Notice that youare not given grams initially, you are given 1.0 gallon. What conversionwill you use to get between gallons and grams? There are 3.785 litersin a gallon. Use 0.703 g/mL as the density of octane.
