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.
