If the only source of the gasoline is that one gas station, then it is point pollution. Nonpoint pollution sources can include leaking vehicles, but a large spill is more than likely from the gasoline station. .
Sure ...
the difference is that a point source pollution comes from a specific site & the non-point source pollution comes from many sources rather than a single specific site. or point source pollution is pollution that comes from a known and specific location. Nonpoint source pollution is pollution that does not have a specific point of orign....................:-)Hisme John
What substance or material that causes pollution

biological indicator of air pollution is lichene. it is a best example of air pollution indicator.

Pollution is any unwanted substance being where it should not be, contaminating the substance. An example could be gasoline spilled on the concrete surface at a gas station. You wanted the gas to go into the fuel tank but some spilled. The spilled gas is a contaminant, not wanted on the concrete. It must be cleaned up before it spreads and gets into the soil or a storm drain and causes more problems.

Any type of chemical that is alien to a water environment in which it is introduced and produces harm to animal life,is a type of pollution. For example, Oil.
A good example is the way gasoline is used in a car.
In a physical change, the substance is still the same substance after the change. But in a chemical change, the substance became another substance with different properties from the original substance.Physical change is changing the appearance of something. Example - Rip a piece of paper - physical change. Burn gasoline - chemical change.
