Environmental Public Health: Indoor Air Quality

Elevated concentrations of indoor air pollutants can exacerbate asthma, allergies, sinusitis, and other health conditions. What are the most problematic pollutants in indoor air? What are effective ways to improve indoor air quality? Learn about these issues in this article.

Indoor air quality (IAQ) relates to the air quality within and around the buildings and structures of buildings, mainly about occupant health and comfort. Awareness and removing common indoor pollutants can help you lower the chance of creating indoor health problems.


Indoor Air Quality (IAQ) Causes;

Tobacco, for example, is a cause of indoor pollution. Smoke, carpet, mold, household items, appliances, radon, pet dander, and HEPA filters are the most common sources of poor indoor air quality in homes. By failing to bring in enough outside air to dilute emissions from interior sources and failing to move indoor air pollutants outside the house, inadequate ventilation can boost indoor pollutant levels. High temperatures and humidity can also provide an increase in pollution levels.

I) Immediate Effects

Some health effects may occur soon after single or multiple exposures to pollution. Some of the symptoms include irritation of the eyes, nose, and throat, as well as headaches, dizziness, and exhaustion. Symptoms like this are usually temporary and treatable.

Many factors, including age and pre-existing medical conditions, influence how quickly people react to indoor air pollution. In some cases, personal sensitivity, which varies greatly from person to person, might play a role in whether or not someone reacts to a pollutant.

It can be difficult to establish if the symptoms are caused by unexplained arthritis because some of the early effects are comparable to those of colds or other viral illnesses.

2) Longer Effects

Other health problems may arise years later or only after prolonged or repeated exposure. Some harmful effects, such as respiratory issues, heart disease, and cancer, can be extremely painful or fatal.

People respond in several ways when they are exposed to indoor air pollution. More research is needed to determine if health effects occur after exposure to average pollutant concentrations seen in homes vs those that happen after short-term exposure to higher attention.

When these items are used indoors, they can produce larger amounts of pollutants, which can be dangerous.

The most problematic pollutants in indoor air are:

  • Asbestos.
  • Biological Pollutants are pollutants that are produced by living organisms.
  • Carbon monoxide is a poisonous gas (CO).
  • Pressed Wood Products/Formaldehyde
  • Lead is a substance that is used to (Pb).
  • Nitrogen Dioxide) (NO2).
  • Pesticides.
  • Radon is a gas that can cause cancer (Rn).
  • Particulate Matter in the Home.
  • Environmental Tobacco/Secondhand Smoke
  • Smoke.
  • Heaters and stoves
  • Chimneys and fireplaces
  • Organic Compounds That Are Volatile (VOCs).

Ways to Improve Indoor Air Quality;

The data presented here is based on the most current scientific and technological understanding of the content of the topic.

1. Managing the source

In general, removing or reducing specific sources of pollution is the most effective way to enhance indoor air quality.

Some sources, such as asbestos-containing materials, can be sealed or contained, while others, such as gas stoves, can have their settings changed to limit emissions. Because increasing ventilation costs money, source management is a more cost-effective way to safeguard indoor air quality than increasing ventilation.

2. Ventilation

The most effective treatment for most indoor air quality concerns in the home is source control.

Ventilation Controlling pollution sources: Eliminating or reducing specific sources of pollution is usually the most effective way to improve indoor air quality. Increasing the quantity of fresh air given indoors helps to reduce pollution. Open windows and doors when the weather allows, or use an air conditioner with the vent control open when the weather allows.

3. Air Purifiers

Air purifiers are quite good at removing particles, The majority of air cleaners aren't designed at removing gaseous pollutants.

Air purifiers, particularly purifiers, can help detect some kind of irritants that may cause your symptoms if they are located in the most repeatedly utilized locations of the house. You won't be able to eliminate these allergies, but you can decrease their living, which may help you.

Consider installing a dehumidifier in wet areas, such as a basement, to help prevent mold development. Make sure toilets, which are also another possible conception of mold, are well circulated and scrub away any noticeable mold that collects in the shower, on fixtures, or the walls.

4. Health Humidity

Humidity, or the proportion of moisture in the air, affects your health. Humidity refers to the moisture in the air that flattens your hair even on the best of days, as well as the heaviness outside that makes you feel sticky and makes the air feel much hotter.

The humidity level in your home is anywhere between 30 and 50 percent. Humidity levels that are either very low or excessively high may cause issues. Low humidity can cause dry skin, inflamed nasal passages and throat, and itchy eyes.

5. House Plants

In this setting, house plants serve several advantages. These plants continue to improve the quality of the air we breathe. This may be accomplished by placing plants in various places throughout the house. They have also been shown in studies to help in the output of cleaner air.
