Question | Answer |
Air Pollution | Contamination of the atmosphere by introduction of pollutants from human and natural sources |
Primary pollutants | are put directly into the air |
Two types of primary pollutants | a. Natural- dust, salt, volcano ash, pollen
b. Human- carbon monoxide, smoke, chemicals |
Ozone | tiny particles or droplets that are mixed in with the air Example: smoke contains particulates (tiny part of burnt material) |
Smog | smoke and fog |
Point source pollution | pollution released from a single source
Example: smoke from factory agricultural waste |
Nonpoint source pollution | pollution from many different sources, hard to identify the origin
Example: smog, ozone |
Indoor pollution | common sources of indoor pollution include emissions from appliances, secondhand smoke, chloride and ammonia (from household cleaners), mold bacteria, carbon monoxide, radon, and formaldehyde (from carpet and furniture |
Acid Rain | rain that contains a high concentration of acids |
Acid Rain Continue | - Sulfur dioxide and Nitrogen oxide from burning fossil fuels combine with water in the temperature
- Can change the nutrient content of the soil, is absorbed by and kills plants
- Can cause acid buildup in rivers and lakes that kills aquatic life |
Effects of air pollution on human health | a. Short term- (temporary)coughing, burning eyes, and sneezing
b. Long term- (Many years, lifetime?) lung cancer |
Air Quality | Standard for air quality are set by the EPA for levels of pollutants such as lead, ozone, and carbon monoxide. The EPA sets standards for each state and regulates/enforces these standards. |
Air Quality Index | The Air Quality Index provides the public with daily information about the quality of the air where they live. Air Temperature greatly affects the quality of air. |
