Pollution
The introduction of contaminates into the land, water or air that harm the environment
Point source pollution
Pollution that comes from a small, specific area or source
Non point source
Pollution that comes from many separate sources, not just one
Resource industry
Leaks from oil and gas drilling
Recreational
Oil spills from boats and cars
Marine transportation
Garbage form freighters, mills and power plants
Land development
Industrial spills, increased run off, increases sediments In water
Point source example
Marine transportation
Recreational
Industrial
Resource industry
Industrial
Waste water form factories, mills and power plants
Non point source examples
Land development Agricultural Storm water run off Sewage treatment Forestry Air pollution from automobiles and industry Water activities
Agricultural
Pesticides, fertilizers, animal waste
Storm run off
Oil, chemicals, and other contaminants from industrial, commercial, and residential sources
Sewage treatment
Sewage leakage, causing bacterial contamination
Forestry
Increase in run off, increased sediments in water, increased erosion
Air pollution from automobiles and industry
Air filled with particles and toxins that become deposited in water supplies
Water activities
Gas and oil spills from boats
What is one of the worst effects of non point pollution? How?
Ground water contamination
Pollutants on the ground can find there way into ground water, then work there way into aquifers
How long does it take for ground water to flow through the pores in rocks
A long time
How many varietys if bacteria decompose oils in the ocean
3
What happenes to the bacteria In a oil spill
The quantity of oil in the ocean overwhelms the bacteria
What things can the ocean not break down
Plastics
Heavy metals
Why is chemical pollutants dissolved in water a concern?
- chemical pollutants are absorbed by fish and other marine organisms
- those contaminated organisms r then consumers by other organisms, including humans
Where does most of the oil come into the ocean by
Comes from run off carrying oil off land from vehicle pollution
How does Acid precipitation form acids
Burning fossil fuels like gasoline and coal introduce nitrogen oxides and sulfur dioxide into the atmosphere
These chemicals react with water in the atmosphere to form acids
