Point source pollution = source of pollution is factories and sewage treatment plants.
Fire discharge pipes, drainage ditches, and smokestacks are a few examples. Manufacturing facilities and power plants have the potential to cause point-source pollution that harms both the air and the water. Carbon monoxide, heavy metals, Sulphur dioxide, nitrogen dioxide, and "particulate matter" (small particles) are just a few of the gases that smokestacks can release into the atmosphere.
When thermal energy from a point source, like a gas source or a nuclear power plant, is produced and escapes the earth as a heat flux, this is referred to as thermal pollution. As a result, it is a single point of pollution.
