Primary air pollutants: Pollutants that are formed and emitted directly from particular sources. When hydrocarbons are emitted and they react with NO x in presence of sunlight, they form ozone. On the ground, acid rain damages plants and trees and increases the acidity levels of soils and bodies of water, causing damage to ecosystems. Primary pollutants include ammonia sulfur dioxide nitrogen dioxide and carbon monoxide. Air pollution is the term for the presence of pollutants in the air. Primary pollutants include ammonia, sulfur dioxide, nitrogen dioxide and carbon monoxide. automobiles and so forth). Nutrient enrichment compounds contain nitrogen and phosphorus. But real acid rain isnt as potent as that. Secondary pollutants are not emitted directly. A primary pollutant is emitted from a single source into the air, where it may contaminate natural habitats and concentrate exponentially over time. Primary air pollutants: Pollutants that are formed and emitted directly from particular sources. Pollutants that are emitted into the environment from a source are called primary pollutants. Explanation: Peroxy Acetyl Nitrateis a secondary air pollutant whereas, Suspended Particulate Matter, SO2and NO2are primary air pollutants. Nutrient enrichment compounds cause air and water pollution, which leads to the rapid growth of algae. The major primary pollutants are Oxides of Sulphur, Oxides of Nitrogen, Oxides of Carbon, Particulate Matter, Methane, Ammonia, Chlorofluorocarbons, Toxic metals etc. Smog is a smelly, toxic haze composed of ground-level ozone, particulate matter, and a variety of other chemicals.
