Nitrogen dioxide , when prevalent in the air, appears as a reddish-brown haze. Nitrogen dioxide and other nitrogen oxides react with other chemicals in the air to form other pollutants, known as secondary pollutants. These secondary pollutants include ozone, particulate matter, acid rain, and other toxic chemicals.
Which of the following air pollutants causes a reddish-brown haze in the sky Brainly?
Nitrogen Oxides as Pollutants
Nitrogen dioxide lends its color to the reddish-brown haze we call smog. Photodissociation of nitrogen dioxide by sunlight produces nitric oxide and ozone in the troposphere, which is another component of smog.
Which of the following air pollutants causes a reddish-brown haze in the sky sulfur Dioxidecarbon Monoxidenitrogen Dioxidecarbon dioxide?
sulfur dioxide carbon monoxide nitrogen dioxide carbon dioxide. Nitrogen dioxide pollutants causes a reddish-brown haze in the sky.
Which of the following air pollutants causes a reddish-brown?
Nitrogen dioxide pollutants causes a reddish-brown haze in the sky.
Is nitrogen dioxide a primary pollutant?
Though nitrogen dioxide can be a primary pollutant , it’s mostly a concern as a secondary pollutant. As a primary pollutant, NO 2 is emitted in limited amounts through vehicles into the air. Nitrogen dioxide is also a secondary pollutant because it can be formed through oxidisation.
Are paint thinners and dry cleaning solvents are considered sources of air pollution?
t/f: Paint thinners and dry cleaning solvents are considered sources of air pollution . t/: Most cancer-causing air pollutants are found outdoors.
Which of the following is an example of point source pollution affecting the US surface water supply?
Point Source Pollution
Examples of point sources include: discharges from wastewater treatment plants ; operational wastes from industries; and. combined sewer outfalls.
Why is ground level ozone considered a pollutant?
Ground-level ozone is a colorless and highly irritating gas that forms just above the earth’s surface. It is called a “secondary” pollutant because it is produced when two primary pollutants react in sunlight and stagnant air . These two primary pollutants are nitrogen oxides (NOx) and volatile organic compounds (VOCs).
Is CO2 a secondary pollutant?
Most of the carbon monoxide pollution comes from burning fossil fuels in vehicles, factories, and power plants, but another major source is from burning wood or crop waste. ... Secondary pollutants like ozone and carbon dioxide (CO 2 ), a greenhouse gas, come from carbon monoxide.
How does nitrogen dioxide affect the body?
Elevated levels of nitrogen dioxide can cause damage to the human respiratory tract and increase a person’s vulnerability to, and the severity of, respiratory infections and asthma. Long-term exposure to high levels of nitrogen dioxide can cause chronic lung disease.
Is no2 a pollutant?
Nitrogen dioxide, or NO 2 , is a gaseous air pollutant composed of nitrogen and oxygen and is one of a group of related gases called nitrogen oxides, or NOx. ... It is one of six widespread air pollutants that have national air quality standards to limit them in the outdoor air.
Does the Clean Air Act regulate VOCs?
EPA does regulate VOCs in some household products under the Clean Air Act (CAA); however, the regulations that we have promulgated for VOCs in architectural coatings and consumer products are in place only because many VOCs photochemically react in the atmosphere to produce ozone, a component of smog.
What is the federal Clean Air Act?
The Clean Air Act is the law that defines EPA’s responsibilities for protecting and improving the nation’s air quality and the stratospheric ozone layer . The last major change in the law, the Clean Air Act Amendments of 1990, was enacted by Congress in 1990. Legislation passed since then has made several minor changes.
What is an example of point source pollution?
The United States Environmental Protection Agency (EPA) defines point source pollution as any contaminant that enters the environment from an easily identified and confined place. Examples include smokestacks, discharge pipes, and drainage ditches .
Which of the following examples is the best example of point source pollution?
Examples of point sources include sewage treatment plants ; oil refineries; paper and pulp mills; chemical, automobile, and electronics manufacturers; and factories. Regulated pollutants from point sources include wastes, soils, rocks, chemicals, bacteria, suspended solids, heavy metals, pesticides, and more.
What are the three main sources of pollution?
There are different types of pollution: water pollution, air pollution, solid waste pollution and noise pollution. All of these can be found in urban areas. The main sources of pollution are household activities, factories, agriculture and transport .
