Air Pollutants

  • Carbon Monoxide.
  • Lead.
  • Nitrogen Oxides.
  • Ozone.
  • Particulate Matter.
  • Sulfur Dioxide.
  • Other Air Pollutants.

What is a pollutant in chemistry?

any substance, as certain chemicals or waste products, that renders the air, soil, water, or other natural resource harmful or unsuitable for a specific purpose.

Is pollution part of chemistry?

Chemistry of air pollution Air is a mixture of gases and particles, some of which are reactive and undergo complex chemical reactions in the atmosphere to form air pollutants such as ozone. Other air pollutants are emitted directly – for example, sulfur dioxide.

How do chemicals pollute?

Examples of Chemical Pollutants These occur in industrial places and activities such as oil refineries, coal power plants, construction, mining & smelting, transportation, agricultural use of pesticides and insecticides, as well as household activities.

What are the 5 major pollutants?

The common air pollutants are:

  • Particulate matter (PM10 and PM2.
  • Ozone (O3)
  • Nitrogen dioxide (NO2)
  • Carbon monoxide (CO)
  • Sulphur dioxide (SO2)

How many chemicals are in the air?

five gases
Nearly all of the Earth’s atmosphere is made up of only five gases: nitrogen, oxygen, water vapor, argon, and carbon dioxide.

What are the 4 types of pollutants?

The major kinds of pollution, usually classified by environment, are air pollution, water pollution, and land pollution. Modern society is also concerned about specific types of pollutants, such as noise pollution, thermal pollution, light pollution, and plastic pollution.

What are pollutants called?

Under the Clean Air Act, the National Ambient Air Quality Standards (NAAQS) are developed by the Environmental Protection Agency (EPA) for six common air pollutants, also called “criteria pollutants”: particulates; smog and ground-level ozone; carbon monoxide; sulfur oxides; nitrogen oxides; and lead.

Does rain have acid?

Normal rain has a pH of about 5.6; it is slightly acidic because carbon dioxide (CO2) dissolves into it forming weak carbonic acid. Acid rain usually has a pH between 4.2 and 4.4.

What is 12th smog?

It is a mixture of smoke, fog and sulphur dioxide. This smog acts as a reducing agent in atmospheric pollution and hence it is also known as reducing smog.

What is toxic pollution?

1) What is toxic pollution? Richard Fuller (RF): Toxic pollution is contaminated water, soil, and air that is harmful or poisonous. It includes industrial wastes like toxic heavy metals from mining or chemicals from factories, and also sewage and particulates from power plants.

What are the 4 types of air pollution?

Types of air pollution

  • particulate matter.
  • nitrogen dioxide.
  • ozone.
  • sulphur dioxide.
