Terms | Definitions |
|---|---|
 Acid Rain (Acid Precipitation) | precipitation such as rain, sleet, or snow that contains a high concentration of acids |
| Air Pollution | when harmful substances build up in the air to unhealthy levels, air pollutants can be solids, liquids, or gases |
| Primary Pollutants | pollutants put directly into the air by human activity |
| Secondary Pollutants | form when a primary pollutant comes into contact with other primary pollutants or with naturally occurring substances and a chemical reaction takes place |
| Smog | results from chemical reactions that involve sunlight, air, auto exhaust, and ozone |
| Short term effects of air pollution | headache, nausea, irritation to the eyes, nose and throat, tightness in the chest, coughing, upper respiratory infections, may worsen asthma and emphysema |
| Long term effects of air pollution | Emphysema, lung cancer, heart disease, may damage lungs of children |
| Sick-building syndrome | condition when buildings have very poor air quality |
| Asbestos | includes several minerals that form in long, thin fibers and are valued for their strength & resistance to heat |
| Noise Pollution | -affects human health and quality of life -airplanes, city traffic, home appliances etc. -heath problems include loss of hearing, high blood pressure, stress, loss of sleep |
| Light Pollution | -Inefficient lighting leads to energy waste -fix:billboards lit from about shooting down |
| Why is smog so common in LA? | Warm and sunny= great environment for trapping and forming air pollutants. Built in a valley surrounded by mountains. Air is trapped off by this natural bowl. When the air higher up is warmer than the air closer to the ground, the warm air acts as a lid that keeps pollutants in. |
| Acid | pH 1-5 |
| Base | pH 8-14 |
| Acid Shock | acidic snow melts and rushes into lakes causing rapid change in pH |
| Canada-U.S. Air Quality Agreement | (pollutants released in US end up in Canada) -acid rain that falls in southeastern Canada often comes from pollution produced in US -both countries agreed to reduce acidic emissions that flowed across the Canada-US boundary |
| Acid Rain Effects | -Toxic metals (Al+Hg) released into environment (poison to humans) -lead to increase in respiratory problems in children -decrease in fish number -can dissolve calcium carbonate in building materials |
| Most polluted cities in the WORLD | Ahwaz, Iran Ulan Bator, Mongolia Sanagaj, India Ludhiana, India Queetta, Pakistan |
| What %s make up clean air | Nitrogen 78% Oxygen 21% (only important ones) |
| SO2 & NO come from | Fossil Fuels |
| Sources of pollution (man made & natural) | household products, power plants, motor vehicles (CO, NO, VOCs) coal burning power plants Particulate Matter-vehicles, incinerators, power plants, mining, wood-burning fireplaces natural pollution (volcano) |
| Causes Smog | Car exhaust |
| Asbestos, Radon, & Ozone- causes & effects | Radon gas- lung cancer Asbestos-damage lungs cause trouble breathing Ozone-skin cancer |
| ID as primary or secondary pollutant acid rain CO Ground level Ozone | acid rain- secondary CO- Primary Ground Level Ozone- secondary |
| How does acid rain form, where does it come from? Causes? (in a diagram) | http://www.epa.gov/bioiweb1/images/acid.jpg |
| Most Air polluted city in the world & country (top 3)? | world- Ahwaz, Iran US-1.) Bakersfield, Calif 2.) Fresno, Calif 3.) Riverside, Calif |
| pH | a value that indicated the acidity or alkalinity of a solution on a scale of 0-14, based on the proportion of H+ ions. |
