Step by step
Solved in 3 steps
- List any three important pollutant of air.According to the EPA, what are the three most dangerous indoor air pollutants? Tobacco smoke, formaldehyde, and methane Tobacco smoke, sulfur dioxide, and ultrafine particles Tobacco smoke, formaldehyde, and radon-222 Carbon dioxide, sulfur dioxide, and methane O Carbon monoxide, nitrogen dioxide, and radon-222What are ways to contribute to the lessening of atmospheric carbon dioxide pollution that can be done by oneself?
- The most abundant constituent of atmospheric air is ? Oxygen Hydrogen Carbon NitrogenAs a result of the Clean Air Act, Congress directed the EPA to establish standards for six pollutants. Which of these is not one of the six? Carbon monoxide Carbon dioxide Sulfur dioxide Nitrogen dioxide LeadUsing the information in the table above, evaluate the relative risk for poor outside air quality for the following pairs of locations in terms of the pollutant sources. Which one do you think would have better air quality? Why? i) small village vs. large city ii) cabin in a forest with a wood-burning stove vs. farmhouse in the middle of the prairies
- Describe the primary sources and some of the health problems associated with each of the following pollutants: carbon monoxide (CO) sulfur dioxide (SO2) volatile organic compounds (VOCs) nitrogen oxidesAir Pollution is a common contributor to health issues that is typically more abundant in urban environments. In this week's lab exercise you will examine levels of air pollution in the Phoenix Metropolitan area. The measurable levels of different pollutants indicate an overall air quality index (AQI). Anthropogenic sources of pollution (Carbon monoxide, Ozone) are a major contributor to higher AQI values but particulate matter (PM-10) is also important in determining an AQI score. Choose all listed sources that would contribute to increased particulate matter (PM-10) levels. and EXPLAIN WHY YOU CHOOSE IT. DEFEND YOUR ANSWER choices: a. Water vapor from Tempe town Lake and local water parks b.Bovine flatulence from Shamrock Farms c.Dust from empty construction lots or a recent HABOOB! d. Pollen from Brenton's ridiculously diverse garden e. Helium expended from the NMR machine in TempeDefine primary and secondary air pollutants?
- 1) Identify the air pollutant you have chosen. a) What is the chemical composition of that pollutant? b) Is this air pollutant a primary or secondary pollutant? 2) Describe what is the primary source/cause of this air pollutant. Where does this air pollutant typically occur, i.e. does it occur in a specific geographic area or part of the atmosphere, or is it widespread? 3) Describe what effects do (or potentially do) this air pollutant have on the environment? Distinguish between a) physical effects on the environment/ecosystems and b) effects on living organisms. 4) Describe (be specific for each) what is being done to control this pollutant from the standpoint of a) laws/provisions of the Clean Air Act (or other laws) b) actual efforts to control its emissions.During which time of year would carbon dioxide concentration be the lowest? winter fall spring summerWhich gas is not a pollutant?
