What kinds of harm does photochemical smog cause?
It irritates your eyes, throat, and lungs. It can also harm plants and other living things. Photochemical smog is formed by the action of sunlight on pollutants such as hydrocarbons and nitrogen oxides. these chemicals react to form a brownish mixture of ozone and other pollutants.
Photochemical smog is formed when primary pollutants interact with?
Sunlight
A thick brownish haze formed when certain gases in the air react with sunlight called?
You Tell me
What forms photochemical smog?
Photochemical smog is formed by the action of sunlight on pollutants such as hydrocarbons and nitrogen oxides. It irritates your eyes, throat, and lungs and can also harm plants and other living things.
Is 'P A N' a secondary pollutant?
No, "PAN" (peroxyacetyl nitrate) is not a primary pollutant; it is a type of secondary pollutant formed through chemical reactions of primary pollutants like volatile organic compounds (VOCs) and nitrogen oxides (NOx) in the atmosphere. PAN is a photochemical smog component formed in the presence of sunlight.
Why is smog black?
Smog is not black. The original smog in London England was formed of sulfur dioxice from coal smoke and fog (hence the name) and was, at best greyer than ordinary fog. The present photochemical smog, formed from automobile exhaust and nitrogen oxides in the presence of sunlight, is brownish yellow when dense enough.
What is a secondary pollutant?
A secondary pollutant is not directly emitted, it is formed in the atmosphere when primary pollutants are mixed as through chemical and photochemical reaction. For example, a secondary pollution would be ozone which is formed when hydrocarbons and nitrogen oxides combine in sunlight
Why are nitrogen dioxide and acid rain called secondary pollutants?
Because they are only caused or formed by pollutants that existed before.
Why plant liberate oxygen in day and carbon dioxide in night time?
because in day in the presence of sunlight the formed their food in this process they inhale co2 snd exhale o2
What altitude is most ozone formed?
Technically ozone is formed at all altitudes by air pollutants such as hydrocarbons reacting by exposure to sunlight. The most concentrated altitude at which ozone is formed at (most commonly known as the ozone layer which is in the stratosphere) starts at about 10km above sea level and goes to about 50km above sea level (in imperial that's about 6 and 31 miles).
Type of smog formed from fossil fuel pollutants with the aid of light?
Photochemical smog
What is a major form of pollution that reduces visibility and is often caused automobile exhaust?
Smog is a major form of air pollution that describes a smoky fog. Smog is formed when vehicle and industrial emissions interact with sunlight. This interaction also creates secondary pollutants.
