What are the causes of indoor air pollution?

Indoor pollution sources that release gases or particles into the air are the primary cause of indoor air quality problems. Inadequate ventilation can increase indoor pollutant levels by not bringing in enough outdoor air to dilute emissions from indoor sources and by not carrying indoor air pollutants out of the area.

What are the major sources of indoor air pollution?

Most of the information below is based on material provided by the Environmental Protection Agency (EPA) or the CPSC.

  • Radon. (Source:Wikipedia.
  • Environmental Tobacco Smoke (Secondhand Smoke) (Image Author: Tomasz Sienicki)
  • Biological Sources.
  • Carbon Monoxide.
  • Nitrogen Dioxide.
  • Organic Gases.
  • Respirable Particles.
  • Formaldehyde.
  • What are some of the causes of indoor air pollution?

    This is what is called outdoor air pollution but it is more dangerous when it becomes indoor air pollution. Indoor air pollution occurs when certain air pollutants from particles and gases contaminate the air of indoor areas. These air pollutants can cause respiratory diseases or even cancer.

    What are the 4 major indoor air pollutants?


  • Mold and pollen.
  • Tobacco smoke.
  • Household products and pesticides.
  • Gases such as radon and carbon monoxide.
  • Materials used in the building such as asbestos, formaldehyde and lead.
  • What are the most common indoor air pollutants?

    This article will help by covering 7 common indoor air pollutants.

  • (1) Pollutant: carbon monoxide (CO) Carbon monoxide is an odorless, invisible gas.
  • (2) Pollutant: radon.
  • (3) Pollutant: nitrogen dioxide (NO2)
  • (4) Pollutant: secondhand smoke.
  • (5) Pollutant: lead particles.
  • (6) Pollutant: asbestos.
  • (7) Pollutant: mold.
  • What are the main sources of air pollution in urban areas?

    Household products, power plants, and motor vehicles are sources of primary pollutants such as carbon monoxide, nitrogen oxide, sulfur dioxide, and chemicals called volatile organic compounds (VOCs). Vehicles and coal-burning power plants are the major sources of nitrogen oxide emissions.

    How can we reduce indoor air pollution?

    Here are some simple steps you can take:

  • Avoid smoking indoors (quitting smoking is the best answer for overall health)
  • Use craft supplies in well-ventilated areas.
  • Make sure your gas stove is well-ventilated.
  • Minimize clutter.
  • Remove carpeting if possible.
  • Use a dehumidifier and/or air conditioner to reduce moisture.
  • What are the causes of Sick Building Syndrome?

    It has been suggested that sick building syndrome could be caused by inadequate ventilation, deteriorating fiberglass duct liners, chemical contaminants from indoor or outdoor sources, and biological contaminants, air recycled using fan coils, traffic noise, poor lighting, and buildings located in a polluted urban area

    What is a natural indoor air pollution?

    Indoor Air Pollutants. Examples. Carbon monoxide – An odorless, colorless gas produced by appliances or heaters that burn natural gas, oil, wood, propane, or kerosene. A major component of car exhaust. Environmental tobacco smoke (ETS) is composed of more than 3,800 different chemical compounds.

    What are the health effects of indoor air pollution?

    The effects of indoor air pollutants range from short-term effects – eye and throat irritation – to long-term effects – respiratory disease and cancer. Exposure to high levels of some pollutants, such as carbon monoxide, can even result in immediate death.

    Why is indoor air more polluted than outdoor air?

    Indoor air pollution, the degradation of indoor air quality by harmful chemicals and other materials, can be up to 10 times worse than outdoor air pollution. This is because contained areas enable potential pollutants to build up more than open spaces do.

    How can I improve the air quality in my home?

    2. Keep a healthy level of humidity.

  • Use an exhaust fan or crack open a window when cooking, running the dishwasher, or bathing.
  • Don’t overwater houseplants.
  • Vent the clothes dryer to the outside.
  • Fix leaky plumbing to prevent moisture-loving mold.
  • Empty drip pans in your window air conditioner and dehumidifier.
  • Why is it so important to have indoor quality air?

    Breathing quality indoor air is critical for good health. Most Americans spend a significant amount of time indoors–either in the home, office or other types of buildings–where gas, chemical and other pollutants can cause headaches, eye irritation, allergies and fatigue.

    What is the process by which an Environmental Protection Act is created and enforced?

    Describe the process by which an environmental protection act is created and enforced. Before a protection act is created, the US Congress must first pass a law to allow its creation. From there, the Environmental Protection Agency creates appropriate regulations for enforcement by state and local authorities.

    What is the cause of sick building syndrome?

    Sick Building Syndrome Can Be Prevented. The term “sick building syndrome” (SBS) is used to describe situations in which building occupants experience acute health and comfort effects that appear to be linked to time spent in a building, but no specific illness or cause can be identified.

    How can we reduce air pollution?

    These steps, as well as many others, are things we all can do to help reduce air pollution. Conserve energy – remember to turn off lights, computers, and electric appliances when not in use. Participate in your local utility’s energy conservation programs.

    What do you mean by indoor air pollution?

    Definition: Indoor air pollution refers to chemical, biological and physical contamination of indoor air. It may result in adverse health effects.

    Why is air quality important to human health?

    Why Air Quality is important. It provides air quality standards and objectives for key air pollutants, which are designed to protect human health and the environment. Air pollution can cause both short term and long term effects on health and many people are concerned about pollution in the air that they breathe.

    What is indoor air?

    Indoor air quality (IAQ) is a term which refers to the air quality within and around buildings and structures, especially as it relates to the health and comfort of building occupants.

    What is urban air pollution?

    Most air pollution is man-made and derives from poor combustion of fossil or biomass fuels (e.g. exhaust fumes from cars, furnaces or wood stoves). Urban outdoor air pollution refers to the air pollution experienced by populations living in and around urban areas (i.e. cities).
