Photochemical oxidant formation. This noxious mixture of air pollutants may include the following: Aldehydes.Nitrogen oxides, particularly nitric oxide and nitrogen dioxide. When the photons present in sunlight combines with atmospheric pollutant molecules, photo chemical smog is formed due to harmful chemical reactions. Photochemical smog depends on primary … The term smog (not to be confused with photochemical smog) is commonly used to represent a near-ground haze made of a combination of smoke and fog rather than ozone, nitric acid, and organic compounds. Photo chemical smog consists of ozone, PAN (peroxyacytyl nitrate), (nitrogen oxides), and volatile organic compounds. Smog is a byproduct of modern industrialization.
Photochemical smog is a type of smog produced when ultraviolet light from the sun reacts with nitrogen oxides in the atmosphere.It is visible as a brown haze, and is most prominent during the morning and afternoon, especially in densely populated, warm cities. There are other sources of outdoor air pollution, such as volcanoes, wildfires, cars, industry, wind dust and fuel emissions. The main components of photochemical smog are nitrogen oxides, Volatile Organic Compounds (VOCs), tropospheric ozone, and PAN (peroxyacetyl nitrate).Hence, the correct option is D …photochemical oxidants, which make up photochemical smog. Explanation: Smog comprises of a mix of smoke and fog. Eran Sher, in Handbook of Air Pollution From Internal Combustion Engines, 1998.

Answers: 2 Get Other questions on the subject: Chemistry. Photochemical smog is a type of air pollution due to the reaction of solar radiation with airborne pollutant mixtures of nitrogen oxides (NOx) and volatile organic compounds (hydrocarbons). Photochemical smog, also known as summer smog, is a type of smog that is produced when UV light originating from the sun interacts with the oxides of nitrogen present in the atmosphere. Photochemical smog is a mixture of air pollutants which have been chemically altered into further noxious compounds by exposure to sunlight. State the formula for density in words and mathematical symbols. Photochemical Smog Reaction: Upon burning fossil fuels, nitrogen oxides NO and nitrogen dioxide NO2 are released. Photo chemical smog is caused mainly due to anthropological activities. Learn vocabulary, terms, and more with flashcards, games, and other study tools. The effects of smog on human health and the environment are serious and harmful. Photochemical smog is a type of air pollution due to the reaction of solar radiation with airborne pollutant mixtures of nitrogen oxides (NOx) and volatile organic compounds (hydrocarbons). Nitric oxide combines with water vapour in the atmosphere to form nitric acid, which is one of the components of acid rain. Smog is a byproduct of modern industrialization. Photochemical smog is formed by a complex series of chemical reactions involving sunlight, oxides of nitrogen, and volatile organic compounds, aldehydes, ketones, PAN and ozone that are present in the atmosphere as a result of air pollution. Photochemical smog consists of. Photochemical smog is a brownish-gray haze caused by the action of solar ultraviolet radiation on atmosphere polluted with hydrocarbons and oxides of nitrogen. Photochemical smog consists of a) coal dust b)water droplets and soot c) ozone d) acid rain.

Other Names: Urban smog Photochemical smog Volcanic smog Vog Photochemical air pollution.
Photochemical smog, often referred to as "summer smog", is the chemical reaction of sunlight, nitrogen oxides and volatile organic compounds in the atmosphere, which leaves airborne particles and ground-level ozone. Some of the toxins created by chemical reactions in the photochemical smog are carcinogenic. Breathing problems can become aggravated due to prolonged exposure to smog conditions.
