Ch. 15 Air Pol Pt. 2
Environmental Ecology- Air Pollution
Term | Definition |
---|---|
Nitrogen Oxide (NO) | N2+O2---(combustion in cars)---> NO Very reactive |
Nitrogen Dioxide (NO2) | NO+O2---->NO2 NO2 reacts with water vapor in air to produce Nitric acid (HNO3)= Acid Rain |
NOX | Variable- cause respiratory problems like irritants to eyes & nose |
Nitrous Oxide (N20) | Greenhouse gas Natural source- animal waste Human source- Fertilizers, burning of fossil fuels |
Sulfur Dioxide (SO2) | Primary source- coal burning, oil refineries SO2+H2O-->H2SO4 (Sulfuric acid)= Acid Rain Highly Reactive |
Particulates | Suspended particulate matter (SPM) <10 Micromiters in size = 1/10,000 M 60% natural sources (Dust, Forest Fires) 40% human sources (Ag, Construction, Tobacco Smoke, exhaust) |
Results of SPM | Irrations of eyes, nose, throat, responsible for genetic mutations (cancer), nervous system damage |
Photochemical Ozone | O3(Chemicals)- smog Respiratory Problems, Lung and Heart Disease, Irritations |
VOC'S | Volatile Organic Compounds Fumes/Ignitable 1/3 Natural Sources- Swamp gas-methine CH4 2/3 Human Sources- Oil/gas wells, gasoline, crude oil "Flaring" |
Radon Gas | Natural radioactive gas (RN) Has the ability to seep into cracks in houses Known producer of lung cancer |
Smog | (Photochemical Response) Chemicals suspended in the air that hits sun light and produces haze like Human Sources- Cars |
Industry Smog | Gray like appearance called gray air smog, induced by industry |
Brown Air Smog | VOC's from cars+NO2+UV+photochemical ozone+heat--->SMOG |
Acid Deposition | 1. Sulfuric Acid (H2SO4) 2. Nitric Acid (HNO3) Comes down as acid rain/snow/dust PH Range <5.6 |
Harmful Effects of Acid Deposition | 1. Respiratory Problems 2. Leaching 3. Damage to Physical Structures 4. Wildlife Damage- direct impact of food chain |
Leaching | Chemical removal process that leaches out toxic metals out of the ground like lead and mercury, and can leach out plant nutrients |
Pollution from Air Pollution | 1. Nasal Hairs (filters pollutants) 2. Upper Respiratory Track- lining coated with mucous and cilia-small hairs. (sneezing & coughing) |
