Environmental Chemistry

1. Chemicals
   1. Heavy Metals

      Nota:

      • Biomagnification- levels of metals increasing as we go up food chain 
   2. Acidity

      Nota:

      • Want it to be close to neutral
   3. Dissolved Oxyogen

      Nota:

      • Essential for life
   4. Nitrogen and Phosphorus

      Nota:

      • Don't want too much or too little
   5. Salts

      Nota:

      • Acids and Bases reacting Low levels of salts are needed
   6. Pesticides

      Nota:

      • Used to kill unwanted pests
2. Biological Indicators
   1. Genetically Engineered Plants: Genetically Engineered Grass that Changes Color If There are Toxins in The Soil
   2. Bacteria

      Nota:

      • Bacteria , Mosses, Tree Bark, Bark Pockets, Tree Rings, Lichens, Leaves, Fungi 
   3. Aquatic Indicators

      Nota:

      • Dragon flys, Mosquitoes, Frogs,
   4. Species used to monitor the health of the ecosystem

1. Chemicals
   1. Carbon Dioxide

      Nota:

      • population increase and deforestation
   2. Carbon Monoxide

      Nota:

      • Pollution from vehicle emmisions
   3. Methane
   4. Sulfur dioxide

      Nota:

      • Burning coal and factory emissions
   5. Ozone

      Nota:

      • VOCs volatile organic compounds
2. Biological Idicators
   1. Lichen

1. Green House Affect
   1. Enhanced Green House Effect

      Nota:

      • How humans contribute to greenhouse effect
   2. Chemicals
      1. Water Vapor
      2. Carbon Dioxide
2. Ozone Layer

   Nota:

   • Protects us from most of the suns UV radiation
   1. Chlorofluorocarbons

      Nota:

      • Organic compound that contains only carbon, chlorine, and fluorine

1. Release at its Source
2. Dispersion

   Nota:

   • When Chemicals travel in all directions
3. Deposition

1. Water Table

   Nota:

   • How much water is at the surface of the earth
2. Permeable Pores

   Nota:

   • Everything can go through it.

Nota:

• Reducing the concentration of a chemical

Nota:

• Something Biological breaking something up. Yellow slime mold

1. Factors Affect Biodegradation

Nota:

• chemical process by which molecules are broken down into smaller units through the absorption of light.

Nota:

• The use of plants that mitigate the environmental problem without the need to excavate the contaminant material and dispose of it elsewhere.

Nota:

• Leachate is any liquid that in passing through matter, extracts solutes, suspended solids or any other component of the material through which it has passed.

Nota:

• The increase in concentration of a substance that occurs in a food chain.

Nota:

• Don't need Alot

1. Seleium

1. Carbohydrates

   Nota:

   • Need   Sugar Simple or complex molocules made of C,H,O
2. Lipids

   Nota:

   • Fats
3. Protiens

   Nota:

   • Meat, eggs, Dairy
4. Nucleic Acids

   Nota:

   • DNA RNA

Nota:

• Need Lots of

1. Nitrogen

   Nota:

   • Makes Proteins Makes Chloraphyl stems leaves Meat
2. Phosphorus

   Nota:

   • Root flower growth Cellular resperation Photosynthesis Making DNA, Bones, Teeth
3. Potassium

   Nota:

   • Stimulates growth Making Protein Fight Disease Making Chloraphyl Muscle contraction Nerve impulse
