   1. Heavy metals

      Anmerkungen:

      • biomagnification- levels of a metal increasing as we go up the food chain
   2. Acidity

      Anmerkungen:

      • Want it to be close to neutral
   3. dissolved oxygens
   4. Nitrogen and Phosphorus
   5. Salts

      Anmerkungen:

      • acid and base reacting low levels of salt are needed
   6. Pesticides
2. Biological Indicators
   1. Plants
   2. Clearness of water
   3. Biomonitor
   4. Aquatic indicators

      Anmerkungen:

      • dragonflysmosquitosbutterflys fish frogs crustaceans
   5. Microbiological Indicators

      Anmerkungen:

      • bacteria viruses fungi algae lichens

1. Chemicals
   1. nitrogen oxides (NOx(g))

      Anmerkungen:

      • forms smog and rain can affect respiratory system and eyes Forms mainly from combustion in vehicles  
   2. sulfur dioxide (SO2(g))

      Anmerkungen:

      • forms smog and acid rain sulfur dioxide and other oxides of sulfur form when oxygen combines with sulfur Also formed by burning fuels such as coal, oil and natural gas
   3. carbon dioxide (CO2(g))

      Anmerkungen:

      • Formed by mainly by human activities
   4. ground level ozones (O3(g)

      Anmerkungen:

      • Formed mainly by fuel combustion in vehicle engines and industry

1. Green House Effect
   1. chemicals
      1. carbon dioxide
      2. Water vapor
      3. Enhanced Greenhouse Effect
2. Ozone Layer
   1. Chloroflourocarbons

      Anmerkungen:

      • The thinning of the ozone layer is caused by our use of chemicals called chloroflourocarbons. UV radition breaks them down and destroys the ozone

1. Release it at the source
2. Dispersion
3. Deposition

1. Water Table

   Anmerkungen:

   • How much water is under the surface
2. Permeable pores

1. Factors affect biodegradation

   Anmerkungen:

   • Bacteria/fungi/worms

Anmerkungen:

• NEEDS LOTS!!!!!!!!

1. Nitrogen

   Anmerkungen:

   • Grows and repairs tissue Makes protein Makes chlorophyll Makes Nucleic acids 
2. Phosphorus

   Anmerkungen:

   • Root and flower growth Cellular respiration Making DNA, bones teeth
3. Potassium

   Anmerkungen:

   • Muscle contractionNerve impulses Stimulates growth Fights diseases Makes chlorophyll  
4. Magnesium

   Anmerkungen:

   • Photosynthesis Makes bones/teeth absorbs calcium and potassium
5. Calcium

   Anmerkungen:

   • Cell walls Cell divison Bones & Teeth Blood clotting Muscles and nerve function
6. Sulfur

   Anmerkungen:

   • Produce fruits and grains Make protein Detoxification

Anmerkungen:

• NEED A LITTLE BIT!!!!
