Non-point source (NPS) pollution refers to both water and air pollution from diffuse sources. Non-point source water pollution affects a water body from sources such as polluted runoff from agricultural areas draining into a river, or wind-borne debris blowing out to sea. Non-point source air pollution affects air quality from sources such as smokestacks or car tailpipes.
Environmental pollution refers to the introduction of harmful pollutants into the environment. The major types of environmental pollution are air pollution, water pollution, noise pollution, thermal pollution, soil pollution and light pollution. Deforestation and hazardous gaseous emissions also leads to environmental pollution.
