APHG: Chapter 11_KI#3
Transcript of APHG: Chapter 11_KI#3
Regional Scale: Water Supply and Vegetation..
U.S. = 4 lbs of waste daily
Sanitary Landfill: U.S. 1/2, but has been declining, due to incineration,, which can be used to generate electricity.
Heavy Metals: Zinc, Cadmium, Mercury, PCB oils, Cyanids, solvents, acids, and cuastics.
U.S. = 1,400 gals consumed per person per day.
APHG: Chapter 11_KI#3
Where Does Industry Cause Problems?
Industry is a major source of Global Pollution.
When more waste enters an environment, than it can absorb.
As economic developed occurs so do carbon emissions, but some regions (Europe) has experienced a decline.
Total domestic and foreign output claimed by residents of a country. GDP + Income from outside the country of origin.
Largest polluters: Power Plants & Cars
Global Scale: Global Warming & Ozone Depletion.
1880 - present = 2 degree temperature increase.
25% increase in carbon dioxide in the atmosphere.
Traps radiation, accelerating the "Greenhouse Effect."
Causes the melting of polar ice caps and a change in weather patterns.
This will cause major political problems due to massive migration.
Th ozone layer helps to protect the earth from the Sun's UV Radiation.
Chlorofluorocarbons break down ozone
Attempts have been made to reduce CFC's.
3 Areas: Northeastern U.S., Western Europe, and East Asia
Sulfer & Nitrogen Oxides + O2 & H20 = Sulfuric & Nitric Acid.
They return to the earth's surface as Acid Deposition, when combined with water vapor they form Acid Precipitation.
Lakes, Soil, Ground Water, Vegetation, and Aquatic Life, Buildings
Local Scale: Urban Photochemical Smog
High Concentration of Factories & Vehicles
Three Components: Carbon Monoxide, Hydrocarbons, & Particulates.
Create repository problems
Worsened by lack of wind, temperature inversion & clear skies.
U.S. = Southern California; Los Angeles
10 most polluted cities are in Developing Countries.
Mexico City's Improved Air Quality due to regulation of emissions .
60% from residences, the remainder from industry
Unwanted byproducts from manufacturing.
EPA: 3.93 billion lbs were released into the environment in 2010
Leaching can contaminate ground water
Easy to dump waste in river or ocean, it becomes someone else s problem.
Point-Source Pollution: Water pollution that originates at a specific source, usually smaller and easier to control
Water using Manufacturers
Steel, Chemicals, Paper producers, & Food Processors.
*All use and pollute large
amounts of water.
Wash pesticides off agricultural products and into water systems.
Industrial accidents: spills. ie Guld Coast spill, West Virginia Chemical Spill.
U.S. Clean Water Act: 1972
Sewage Treatment plant, then back into ocean, lake, or river.
*Developing Countries lack regulation and infrastructure.
Cholera, Typhoid, and Dysentery
Pollute in greater quantities and are harder to regulate.
Agriculture: Fertilizers & Pesticides.
The Salton Sea
Impact of Water Pollution
on Aquatic Life
(BOD) Biochemical Oxygen Demand
Decomposing organic matter compete for oxygen, killing aquatic life, by depriving them of oxygen.
Fertilizer nourishes algae "Pond Scum," increases competition for oxygen.
Industrial outputs may also raise the temperature of water, thus killing hot sensitive aquatic life
