_____________________ pollution comes from multiple locations that are not easy to define.
The term nonpoint source i…s defined to mean any source of water pollution that does not meet the legal definition of point source in section 502(14) of the Clean Water Act. Indoor areas can become polluted by emissions from smoking and cooking. Some of these chemicals, when released into the air, contribute to smog and acid rain. Short term exposure to air pollution can irritate the eyes, nose and throat and cause upper respiratory infections, headaches, nausea and allergic reactions. To trace an epidemic back to its source, you should first find the  common denominator between the infected. Next, you work your way  backwards after finding each common fac…tor until you reach the  source. Nonpoint source pollution. Non-point source (NPS) pollution includes 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. Although these pollutants have originated from a point source, the long-range transport ability and multiple sources of the pollutant make it a non-point source of pollution. Air pollution means the presence of one or more unwanted substances in air. Air pollutants have a negative impacts on humans, animals and plants, and on air quality. The main sources of air pollution are the industries, agriculture and traffic, as well as energy generation. During combustion processes and other production processes air pollutants are emitted. What is the difference between point and nonpoint sources of pollution? 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 poin…t source pollution is pollution that comes from a known and specific location.

During energy generation chemicals such as methane are released into the air as a result of oil and natural gas extraction. The combustion of coal and natural gas for electricity production causes the release of sulphur dioxide, nitrogen oxides and carbon dioxide into the air. Rain can remove pollutants from air, causing soil and water pollution. Sunlight can aid the convertion of air pollutants to different substances. Chemicals can come from various sources, and are formed during different processes. Non point source water pollution is difficult to control because it comes from the everyday activities of many different people, such as fertilizing a lawn, using a pesticide, or constructing a road or building.
