what is the difference between point and nonpoint sources of air pollution?

Point-source pollution is easy to identify. As the name suggests, it comes from a single place. Nonpoint-source pollution is harder to identify and harder to address. It is pollution that comes from many places, all at once.

Non-ionizing radiation is longer wavelength/lower frequency lower energy. While ionizing radiation is short wavelength/high frequency higher energy. Ionizing Radiation has sufficient energy to produce ions in matter at the molecular level.

One of the most useful describes pollution in terms of its source and effects. Using this framework, the three main categories of water pollution are point-source, nonpoint-source and trans-boundary.

Radiation is classified as being either non-ionizing or ionizing. Non-ionizing radiation is longer wavelength/lower frequency lower energy. While ionizing radiation is short wavelength/high frequency higher energy. Ionizing Radiation has sufficient energy to produce ions in matter at the molecular level.

NOx pollution is emitted by automobiles, trucks and various non-road vehicles (e.g., construction equipment, boats, etc.) as well as industrial sources such as power plants, industrial boilers, cement kilns, and turbines. NOx often appears as a brownish gas.

Smog formation in general relies on both primary and secondary pollutants. Primary pollutants are emitted directly from a source, such as emissions of sulfur dioxide from coal combustion. Secondary pollutants, such as ozone, are formed when primary pollutants undergo chemical reactions in the atmosphere.

Air pollution Burning fossil fuels emits a number of air pollutants that are harmful to both the environment and public health. Sulfur dioxide (SO2) emissions, primarily the result of burning coal, contribute to acid rain and the formation of harmful particulate matter.

Campfires are indeed a source of air pollution. Burning wood releases a surprisingly large number of compounds, including nitrogen oxides, carbon monoxide, particulate matters, benzene, and many other potentially toxic volatile organic compounds (VOCs).

Contamination is simply the presence of a substance where it should not be or at concentrations above background. Pollution is contamination that results in or can result in adverse biological effects to resident communities. All pollutants are contaminants, but not all contaminants are pollutants.

Air pollution itself is an abiotic factor for a given ecosystem, but air pollution doesn't have abiotic/biotic factors attached to it. Abiotic and biotic factors are terms which refer to ecosystems.

The difference between the single point and multi point is: A single point heater serves only one location, i.e, a sink, a basin etc. A multi point is generally a boiler that serves more than one draw off point in your home (a draw off point is controlled by a Tap/Faucet).

Ground-level ozone is a colorless and highly irritating gas that forms just above the earth's surface. It is called a "secondary" pollutant because it is produced when two primary pollutants react in sunlight and stagnant air. These two primary pollutants are nitrogen oxides (NOx) and volatile organic compounds (VOCs).

Sulphur dioxide is the byproduct of these industrial processes and causes acid rain. Smog is a kind of heavy and dark photochemical haze formed when pollutants interacts with sunlight. ... All of the above sources produce Sulphur dioxide and Nitrogen oxides. Acid rain is produced when these particles react with rain water.
