Which Substance Is An Indoor Air Pollution?

1. Biological Pollutants

Biological pollutants include dust, viruses, pollen, and other contaminants produced by living creatures. They’re also common in areas where there’s a lot of food or a lot of moisture. 

For instance, humidifiers or an unventilated bathroom provides the ideal habitat for mold, mildew, and bacteria to thrive, which is why these pollutants are commonly found in your buildings.

2. Asbestos

Asbestos is a mineral fiber that can pollute your home and is one of the most toxic indoor air pollutants examples. It has been used in various construction materials, including insulating, roof shingles, and as a flame retardant, due to its strength and heat resistance. 

Asbestos exposure can raise the risk of lung illness, mesothelioma, and asbestosis.

3. Wood Smoke

When wood and other plant debris are burned, smoke, a complex combustible gas, and minuscule microscopic particles are produced. Many individuals still use wood stoves for cooking and heating their houses. 

They supply essential warmth, but they can generate deadly smoke if not adequately ventilated. We should replace old wood stoves with modern, cleaner technologies to avoid health risks.

4. Environmental Tobacco Smoke

Secondhand smoke is a mixture of tobacco smoke from cigarettes and cigars. Passive smoking, or exposure to secondhand smoke, can cause heart attacks, lung cancer, asthma attacks, stroke, and other lung problems.

5. Pesticides

Pesticides are chemicals that kill or control insects and bacteria, and other microbes. Insecticides, termiticides, and antiseptics are examples of indoor pesticides.

This air polluted substance irritates the eyes, nose, throat, nervous system, and kidneys and raises cancer risk.

6. Carbon Monoxide

According to the indoor air quality standards chart,  CO comes with an extreme hazard level. It is a colorless, odorless, and very poisonous gas. Depending on the concentration, it may induce acute illness and death. You can find CO in the oven, gas appliance, and heating system exhaust gasses.

When humans inhale them, they will have headaches, dizziness, tiredness, vomiting and chest discomfort due to the poisoning.

However, because the following symptoms are frequently mistaken with other ailments, it can be difficult to identify if someone is suffering from CO poisoning.

7. Excess Moisture

Your health and the house you live in are both affected by humidity. Mold and dust mites grow when water gathers on surfaces. Asthma and allergy responses are caused by mold and dust mites.  

Through capillary action, basement leaks and rain will raise humidity levels in your home. Humidity is also increased by activities in the kitchen.

8. Radon

Although radon is invisible, odorless, and tasteless, it can be extremely dangerous to your house. The breakdown of uranium molecules in soil, gravel, and water produces radon.

Radon levels are often lower outside than inside. The substance can seep into homes and apartments through gaps in the flooring, walls, and other structural elements. Water, particularly freshwater, contains radon as well.

9. Volatile Organic Compounds

VOCs are gaseous byproducts of liquids or solids. Indoor VOC concentrations are higher than outdoors. They are mostly produced by paints, aerosols, disinfectants, and insecticides. 

You may experience nausea, eye and nose irritation, migraines, and kidney and liver damage after exposure to VOCs.

10. Lead

You can find lead in house dust, drinking water, ceramic glazes, and metal jewelry.

Breathing, drinking, eating foods contaminated with lead, and coming into contact with lead-based products can all have major health consequences.

Lead can induce infertility, neurological issues, musculoskeletal pain in adults, and elevate blood pressure. It also has an impact on memory and concentration.

Causes Of Indoor Air Problems

Where does indoor air pollution come from? Poor ventilation can cause indoor pollution by failing to bring in enough outside air to balance. High temperatures and humidity can exacerbate pollution levels.

Vehicles, construction sites, cleaning, maintenance, industrial facilities, production workshops, and other dust sources can all be found in the surrounding living environment. Daily household trash leads to the production of dust, which pollutes the air in your home.

Changes in humidity, temperature, etc., cause mold, dust mites, dangerous compounds, and hazardous emissions to arise in the air. More serious air pollution is the result of this transformation.

Effects Of Indoor Air Pollution 

Immediate Effects

Some health impacts may appear soon after a single or several pollution exposures. Itchiness of the eyes, nose, and throat, as well as headaches, dizziness, and fatigue, are among them. Don’t worry too much! These kinds of acute effects are usually temporary and curable.

However, don’t bet on it! This is because a variety of factors increase the chances of having an extreme reaction to indoor air pollution, including age and whether or not medical issues existed at the time. 

Symptoms like asthma may arise, worsen, or disappear quickly following exposure to certain indoor air pollutants.

Long-Term Effects

Other health problems may manifest years after exposure or only after prolonged or repeated exposure. Some lung disorders, heart disease, and cancer are among the impacts that can be very disabling or deadly.

Indoor air pollution also has the greatest impact on children, women, pregnant women, the elderly, and those with poor health.


Why Is Indoor Air Pollution More Dangerous Than Outdoor Air?

Because indoor air has less circulation, it is more susceptible to indoor emissions such as cigarette smoke, cooking, toilet odors, cleaning chemicals, mildew, or chemicals.

For enclosed rooms, indoor air is thicker and more difficult to circulate than outdoor air. It is quite easy to develop asthma, allergies, heart and lung disorders, and even cancer in an indoor environment that has accumulated for a long time. 

How To Reduce Indoor Air Pollution?

Let’s check the useful methods below to help you know how to improve indoor air quality.

1. Open the windows or doors 

Opening windows and doors to create a proper interchange of indoor and outdoor air is a simple technique to encourage healthy indoor air.

2. Cleaning the house regularly

The first step in improving indoor air quality is to keep it clean. Washing, sweeping, and cleaning furniture and floors should all be done on a regular basis. 

Doing this, you can prevent dust from building up and creating an ideal environment for bacteria to thrive.

3. Plants that can purify the air

Many individuals also utilize the plants to create stunning scenery in their homes. Plants are not only attractive, but they also have the potential to absorb CO and CO2 as well as a variety of other toxins, keeping your home fresh and clean.

4. Take off your shoes before entering home

The dirt is usually carried outside by the shoes. When you wear shoes inside your house, you expose your home and family to various toxins. Make it a habit to regularly remove your shoes before entering the house and clean your shoes’ soles.

5. Use an air purifier

The air purifier is a device that combines ion technology with a standard filter to help reduce dust particles, smells, allergies, mildew, and other contaminants. When combined with UV sterilization radiation, hazardous chemicals are eliminated and regenerated into harmless by-products.

How Does Outdoor Air Enter a Building?

Infiltration, air circulation equipment, and ventilators are all ways for outdoor air to enter and exit a building: 

  • Infiltration: Outdoor air enters buildings through holes, joints, and cracks in sidewalks, floors, ceilings, and around windows and doors.
  • Natural ventilation: Air flows combine toxic substances through opened windows and doors. 
  • Mechanical ventilation devices:  Range from open-air fans to air handling systems that use fans to occasionally remove air from a private room, such as restrooms and kitchens.
