Land and water pollution

In order for something to be a potential pollutant, it has to be

• synthetic or manufactured by humans

• a form of waste or garbage

• Able to reach a concentration that interferes with ecosystem function

• None of the above

Which of the following could NOT be a potential pollutant?

• Light

• Sound

• Carbon Dioxide

• Heat

• All of these could become pollutants

Which is easier to fix, non-point or point source pollution.

• Point-source pollution

• Nonpoint Source pollution

True or False: Different Substances become toxic at different concentrations.

• True

• False

If a substance can biomagnify, concentrations of that substance would potentially increase toxic levels as it moves up the food chain.

• It should be able to be used because at low levels because it isn't toxic.

• It should NOT be able to be used because at low levels because it isn't toxic, but it biomagnifies.
