Chapter 10: Air Pollution Flashcards
What is the El Niño effects?
Caused heavy monsoons or serious droughts.
What are some reasonable effects of global climate change on California?
Drought and wildfire
What is primary air pollutant?
Chemicals released directly into the air in a harmful form.
What is secondary air pollutant?
Chemicals modified to a hazardous form after entering the air or that are formed by chemical reactions as components of the air mix and interact
What is point source emissions?
Specific locations of highly concentrated pollution discharge, such as factories, power plants, sewage treatment plants, underground coal mines, and oil wells.
What is non-point source emissions?
Scattered, diffuse sources of pollutants such as runoff from farm fields, golf courses, and construction sites.
When children and adults are in the same environment, provide 3 reasons why children will be more affected by air pollution?
Immune system is still immature, children breathe more rapidly than adults, children are outdoors more than adults.
Why can indoor air actually be more of a problem than outdoor air for human health? Which segments of the population are more at risk for indoor air pollution problems?
Because people generally spend more time inside than out, they are exposed to higher doses of these pollutants. Africa, Asia, Latin America.
What is ozone?
A highly reactive molecule containing three oxygen atoms; a dangerous pollutant in ambient air.
What is destroying stratosphere ozone, and where does this happen?
Chlorofluorocarbons (CFCs) and hydro chlorofluorocarbons (HCFCs).in the southern spring time
What is Montreal protocol? Has it been successful?
An international treaty to eliminate chlorofluorocarbons that destroy stratosphere ozone.
It has helped reduce climate change so yes.
What is acid precipitation? Name three major effects of acid precipitation.
Acidic rain, snow, or dry particles deposited from the air due to increased acids released by anthropogenic or national resources.
High-elevation forests, lakes in Scandinavia, and forests and crop lands.
What is El Niño?
A climate change marked by shifting of a large warm water pool from the western Pacific Ocean toward the east. Wind direction and precipitation patterns are changed over much of the pacific and perhaps around the world.
