Whats the difference between industrial and photochemical smog?
Industrial smog occurs in foggy, cool weather typical of that experienced in the British Isles and the eastern seaboard of the United States. Photochemical smog, on the other hand, occurs in hot, dry climates, and particularly on sunny days.
What is industrial smog?
Industrial smog typically exists in urban areas where factories burn fossil fuels such as coal, which creates smoke and sulfur dioxide that mix with fog droplets to create a thick blanket of haze close to the ground.
What are the causes of photochemical and industrial smog?
Photochemical smog is produced when sunlight reacts with nitrogen oxides and at least one volatile organic compound (VOC) in the atmosphere. Nitrogen oxides come from car exhaust, coal power plants, and factory emissions. VOCs are released from gasoline, paints, and many cleaning solvents.
What is the difference between industrial smog and photochemical smog in terms of their chemical composition and formation?
industrial smog is an unhealthy mix of sulfur dioxide, suspended drop- lets of sulfuric acid, and a variety of suspended solid particles. Photochemical smog is a mixture of primary and secondary pollutants formed under the influence of UV radiation from the sun.
What is the difference between the two types of smog?
Photochemical smog (Los Angeles smog) It forms mainly in the summer months when temperatures reach high levels. Los Angeles smog consists mainly of carbon oxides, nitrogen oxides, and hydrocarbons. Contrary to sulfurous smog, photochemical smog originates from exhaust fumes and industrial emissions.
How does photochemical smog differ from industrial smog quizlet?
Photochemical smog is produced from reactions with light while industrial smog is produced from factories burning coal. Weather can move smog with wind and topography can trap smog between mountains or valleys.
What is meant by photochemical smog?
Photochemical smog is a mixture of pollutants that are formed when nitrogen oxides and volatile organic compounds (VOCs) react to sunlight, creating a brown haze above cities. It tends to occur more often in summer, because that is when we have the most sunlight. Primary pollutants.
What is the main cause of industrial smog?
Coal-burning power plants and factors are by far the leading source of the chemicals that cause industrial smog, according to the Union of Concerned Scientists. A single coal power plant produces more than 7,000 tons of sulfur dioxide per year, even with state-of-the-art pollution control.
What is the main source of industrial smog?
Apparently, this is a logically depiction given that the main source of industrial smog was from the burning of coal for heat and energy (Nebel and Wright 527). As a result, the main pollutant of industrial smog is sulfur dioxide-a compound largely responsible for acid precipitation.
What are the effects of industrial smog?
Those who don’t die during a smog event may develop a number of short- or long-term health effects, including inflammation of the lungs and permanent lung damage, reduced oxygen in the lungs due to a elevated levels of carbon monoxide and an increased risk of cancer. Children may become more susceptible to disease.
What are the types of photochemical smog?
At least two distinct types of smog are recognized: 1) Sulfurous smog (or ‘London-type’ smog); 2) Photochemical smog (‘Los Angeles-type’ smog). Sulfurous smog results from a high concentration of sulfur oxides in the air and is caused by the use of sulfur-bearing fossil fuels, particularly coal.
What is industrial smog quizlet?
industrial smog. Type of air pollution consisting mostly of a mixture of sulfur dioxide, suspended droplets of sulfuric acid formed from some of the sulfur dioxide, and a variety of suspended solid particles. Compare photochemical smog.
How photochemical smog is formed?
Photochemical smog is a mixture of pollutants that are formed when nitrogen oxides and volatile organic compounds (VOCs) react to sunlight, creating a brown haze above cities. It tends to occur more often in summer, because that is when we have the most sunlight.
What is photochemical smog explain?
What is in photochemical smog?
What is industrial smog and its effects in the environment?
Smog affects much more than just human lives; it also has a large impact on the surrounding physical environment. Ozone and PM in particular cause damaging effects: Ozone can damage plant cells and inhibit their growth, reducing the amount of carbon dioxide that they take in during photosynthesis.
What is photochemical smog give example?
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.
How does classical smog different from photochemical smog?
Q:- What will be the pressure of the gaseous mixture when 0.5 L of H 2 at 0.8 bar and 2.0 L of dioxygen at 0.7 bar are introduced in
What causes industrial smog?
Pulmonary health issues. Since smog is composed of many particles and elements that are quite harmful to our health,it can lead to many different pulmonary diseases.
What are problems caused by photochemical smog?
– In 2018, about 76 million tons of pollution were emitted into the atmosphere in the United States. – Burning fossil fuels is the leading cause of pollution in the States. – Texas ranks as one of the most heavily polluted states in the U.S.
What is the main component of industrial smog?
Industrial smog contains two primary components: sulfur dioxide and particulates, which include dust and soot from burning coal for heat and fuel. Which is not component of smog? Classic smog results from large amounts of coal burning in an area and is caused by a mixture of smoke and sulfur dioxide.
