primary pollution
When the atmosphere is contaminated by pollutants from human and natural sources, it is referred to as air pollution. This pollution can have harmful effects on human health, the environment, and the climate. Major sources of air pollution include vehicle emissions, industrial activities, and natural events like wildfires.
secondary pollutant. deals with oxygen in air
Nitrogen oxide is considered a primary pollutant because it is directly emitted into the atmosphere from sources such as vehicle exhaust and industrial activities.
Natural sources of pure water include springs, glaciers, and rainwater. These sources typically have not been contaminated by human activities and provide water that is free from pollutants and chemicals. It is important to note that even water from natural sources may require testing to ensure it is safe for consumption.
Water can become a water pollutant when it is contaminated by harmful substances such as chemicals, heavy metals, pesticides, or pathogens. These contaminants can come from various sources including industrial discharge, agricultural runoff, sewage discharge, and oil spills, leading to water pollution that can harm aquatic life, human health, and the environment.
Methane is naturally produced by sources like wetlands, oceans, and animals. These sources release methane into the atmosphere, where it acts as a greenhouse gas, trapping heat and contributing to global warming.

Brown haze from soot, soil erosion, volcanic ash.
Mostly HNO3 (Hydro nitrogen trioxide) this is the main one and also along with CO1/2/3 SO1/2/3 which are Carbon,Monoxide, Dioxide, Trioxide and Sulfur Monoxide, Dioxide, Trioxide.Hope this helped. Varian Wyrnn.

Natural sources of these gases include volcanic eruptions, wildfires, and decomposition of organic matter. Man-made sources include burning fossil fuels, industrial processes, and deforestation. Both natural and man-made sources contribute to the levels of these gases in the atmosphere.
Two natural sources of the greenhouse effect are water vapor and carbon dioxide. Water vapor is the most abundant greenhouse gas in the atmosphere, while carbon dioxide is released through natural processes such as respiration and volcanic eruptions.
