What are some examples of point sources of air pollution?
Examples include smokestacks, discharge pipes, and drainage ditches . Factories and power plants can be a source of point-source pollution, affecting both air and water. Smokestacks may spew carbon monoxide, heavy metal, sulfur dioxide, nitrogen dioxide, or “particulate matter” (small particles) into the air.

What are the point and non point sources?
Point Source Pollution
Point sources release pollutants from discrete conveyances , such as a discharge pipe, and are regulated by federal and state agencies. The main point source dischargers are factories and sewage treatment plants, which release treated wastewater.
What type of pollution that comes from multiple sources?
Nonpoint source pollution is difficult to control because it comes from many different sources and locations. Most nonpoint source pollution occurs as a result of runoff. When rain or melted snow moves over and through the ground, the water absorbs and assimilates any pollutants it comes into contact with.
What do you mean by point source?
