Indoor Air pollution

Internal air pollution is a very dangerous thing because the internal air is more contaminated than the outdoor air pollution. It is estimated that 2.2 million deaths per year are due to domestic air pollution

Indoor Air pollution (Hidden Pollution In Our Homes )

When you think of  air pollution, it is possible that you think of things like smog, electricity plants and pollution from cars and trucks. These are all examples of external Air pollution, but the inner air is more polluted. There are many harmful contaminates  in the pollutant air; So domestic air pollution occurs when chemicals from pollutants such as gases and particles contaminate the indoor air.

Statistics About Indoor Air Pollution 

  • Living with mould increases the risk of asthma by 40%.
  • Indoor air pollution is responsible for 99,000 deaths in Europe every year.
  • Indoor air pollution is 3.5 times worse than outdoor air pollution
  • 600 000 deaths from respiratory infections and tuberculosis

Mold or Mould --  

                                  Molds are a form of fungus. Molds grow best in moist, warm and humid environments - easily created in the home during the winter.

Indoor Air Pollution Examples 

Internal air pollution is a very dangerous thing because the internal air is more contaminated than the outdoor air pollution. It is estimated that 2.2 million deaths per year are due to domestic air pollution (compared to 500,000 deaths from outdoor air pollution). There are many sources of indoor air pollution, but they are different for development and developing countries. We will first look at the developing countries to see how indoor air pollution in these places.

Indoor Air in Developing Countries

Indoor air pollution has a far greater impact on developing countries than it does on developed ones because fuel, such as wood, charcoal and animal dung, is mostly used to make food. There is Rarely proper ventilation to allow the pollutants to escape, so these contaminated pollutants are very dangerous to our Health.

These Indoor air pollutants from  burning of Solid fuel lead to serious human health problems, such as pneumonia, bronchitis, cancer, heart disease and asthma (respiratory problems).

{solid fuel}*
                - Solid Fuel refers to various forms of physical materials that can be burned to mix energy, heat and light can be provided through the combustion process. ... Common examples of solar fuel include timber, charcoal, peat, coal, wood summer, corn, wheat, mustard and other grains.

Indoor Air in Developed Countries

An average American spends about 90% of their lives indoors. You may think that even in developed nations, there may be indoor air pollution. It is a bit difficult to believe, but it is true that in developed countries like America, there is a large amount of indoor air pollution. The two most dangerous indoor air pollutants in Developed countries  are tobacco smoke and radon.

1. Tobacco Smoke is a major cause of Indoor air pollution.  Even if you are not a smoker, secondhand smoke can cause many of the same health problems as directly inhaling from cigarettes - things like lung cancer, emphysema, asthma and heart disease. Even if inhaling secondhand, you are still taking in over 4,000 chemicals, a large number of which are carcinogens, or cancer-causing chemicals.

 According to WHO's  new report -- 8 million people die each year because of tobacco.
60,000 children die every year because of second-hand smoking.

3.3 million tobacco-related deaths - more than 40 % of the total - come from lung diseases, such as cancer, chronic respiratory diseases and tuberculosis.
Out of that 3.3 (million), about half a million people are those who are exposed to second-hand smoke and die from it.

2. Radon Gas is the second major cause of lung cancer by indoor air pollution in America.  Radon gas is a radioactive gas which comes from the natural breakdown of uranium in rock,soil  and water. When the uranium breaks down, the radon gas seeps up and can get into buildings. Radon is mainly  dangerous because it is  colorless and odorless, which makes it impossible to detect without special testing equipment.

Apart From tobacco and radon, volatile organic compounds (VOCs) create a variety of pollutants in indoor air.Concentrations of  VOCs are consistently higher in  indoors (up to 10 times higher) than outdoors. VOCs are carbon-containing compounds that are released by common products which are used in everyday life - Such as  perfume, paint, plastic, household cleaners, adhesives, furniture, carpet etc. 

 Living things can also create indoor air pollution. Things like dust mites, pet dander, mildew and airborne bacteria are all living creatures that cause human health problems by polluting indoor air.

Causes of Indoor Air Pollution 

1. SecondHand Tobacco smoke -  second hand tobacco contains  over 4,000 chemicals, a large number of which are carcinogens, or cancer-causing chemicals.

2. Dry cleaned clothes- which contains trichloroethylene {(TCE) is a volatile, colorless liquid organic chemical}. and perchloroethylene (PCE), which are highly toxic substances that are known to cause cancer.

3. Daily based Used Household cleaning chemicals, paints and solvents-- These products contain volatile organic compounds (VOCs) that cause sick building syndrome such as headaches, skin and throat irritation when people are regularly exposed to them.

4. Insecticides, herbicides and pesticides--  Vapors of agricultural chemicals contain toxic substances such as arsenic that are known to destroy the endocrine system and lead to cancerous growth.

5. Synthetic fragrances, perfumes----  Substances like perfumes and deodorizers are largely unregulated and are not monitored by the government. Some of the highly volatile and semi-volatile chemicals have been found to be toxic and are able to cause allergic reaction, cancer, birth defects, central nervous system disorders, and reproductive disorders.

6. Radon Gas --    Radon Gas is the second major cause of lung cancer by indoor air pollution in America.  Radon gas is a radioactive gas which comes from the natural breakdown of uranium in rock,soil  and water.   

Apart from these main causes Dust, Fumes from paraffin wax candles, volatile organic gases released by building, chlorine products are also responsible for air pollution.

How to Reduce Indoor Air Pollution

1. To avoid indoor pollution, it is important to avoid the disruption of air in your home. Install the ventilation system in your house in such a way that clean air coming and going home at all times. Especially you have better ventilation in your living and kitchen areas, you can avoid pollution. There are many solutions for this, which you can use. Chimneys, big windows, smoke hoods, etc. can be helpful.

2. We often use  plastic  plants to decorate our homes to give it a fresh look. There is dust clay on them, which can give us allergies. In this context,you should avoid using such items.

3. Pollution is present in mattresses, pillows, sheets, sofas, even carpets in our homes, which we do not see by naked eye. Keep washing them time to time. At least they should be kept dusting time to time.

4.  Many Things that are present inside the house, which emit carbon in environment. In most of the houses, lamps, incense, candles, camphor etc. are burnt, which causes smoke in the house. The climate of our home is polluted by this same smoke, which adversely affects our health. Therefore it would be good to keep these things out of the house or to use in limited quantities.

5. Use Alternative of Solid Fuel -- Indoor air pollution can be drastically reduced, if we use alternate fuels instead of solid fuel such as biomass, wood, coal etc. Nowadays there are many such options, such as LPG, biogas, solar energy and electricity etc.

6.  Plants not only make our homes beautiful, but also provide us fresh air. With fresh air we can overcome pollution in our home. For this, we should plant some plants in our home, which absorb polluting factors. Such as money plant, aloevera, green basil, boston fern, sensoria plant etc.

7. Reduce levels of moisture by, for example, drying clothes outside, ensuring extraction fans are switched on in the bathroom and kitchen, covering pans when cooking and shutting the bathroom door when showering

  1. I have had asthma my whole life but about 5 years ago my asthma got so bad and I was diagnosed with emphysema/COPD which was most likely due to the asthma. I was on double antibiotics and steroids, still didn't feel any better. I already used Advair, Spiriva, and albuterol in my nebulizer, they just didn't do much. It was awful for me due to the difficulty in breathing, nothing gave me better relief from the severe breathlessness and Wheezing till i started on this COPD Herbal from Organic Herbal Clinic ( w ww.organicherbalclinic.c om )Its been 4 months since i completed the Emphysema Herbal Formula, all my symptoms are gone including constant coughing, i breath very much easier and  can never be thankful enough to nature

  2. More than two billion people worldwide continue to depend on solid fuels, including biomass fuels (wood, dung, agricultural residues) and coal, for their energy needs. Cooking and heating with solid fuels on open fires or traditional stoves results in high levels of indoor air pollution. Indoor smoke contains a range of health-damaging pollutants, such as small particles and carbon monoxide, and particulate pollution levels may be 20 times higher than accepted guideline values. delhi pollution
