Top 4 areas of concern: Water Pollution
SOC
IOC
Sediments
Dissolved Oxygen
Examples of SOC
Oil & pesticides
SOC pollutant can have long range effects like:
Bio-magnification
IOC
detergents
Phosphates
IOC salts
NaCl
IOC toxic metals
Arsenic
Lead
Mercury
Copper
IOC fertilizers
Nitrates
Nitric acid formula
NOX + N2 + H2O = HNO3
Sulfuric Acid
SO2 + H2O = H2SO4
The largest form of water pollution
Sediments
Natural rates of erosion lead to
Aquatic Succession
Increase Oxygen in water
Cold
High speed
Less pollutants
Rough surface
