familiarity with Allergenic Chemical pollutants inside the house

There are many other chemicals inside the house that endanger human health from various aspects!

1. carbon monoxide (resulting from the combustion of fossil fuels)
2. Asbestos (used in some construction materials and household items)
3. Lead (found in many household items and building materials such as water pipes)
4. Building paints or radon gas (found in building materials)

According to the definition of the World Health Organization (WHO), volatile organic compounds include compounds that have at least one carbon molecule and one hydrogen molecule in their chemical structure and have a melting point lower than room temperature.
It is worth noting that these compounds are usually separated from the production source in the form of gas and people will be exposed to them indoors or in roofed environments.
Studies have shown that humans are exposed to volatile organic compounds in the indoor environment more than 2 to 5 times compared to the outdoor environment.
Sometimes, the concentration of fugitive chemical compounds immediately after some activities, such as building painting, reaches more than 1000 times the amount outside the house!

1. Organic compounds in insecticides
2. Chemical aerosol sprays (dispersion of solid or liquid particulates in a specific gas phase or in the air is called aerosol)
3. Materials used in copiers and printers, error-proof varnishes, compounds for the appearance of photos or all kinds of markers, especially markers used for marking in books.

1. Increase ventilation when products containing volatile chemical compounds are used.
2. Be sure to read the label on the container before using products containing volatile chemical compounds and take the precautions stated by the product manufacturer seriously!
3. Never store containers containing volatile chemical compounds (such as building paints) with the door open inside the house!
4. When using products containing volatile chemical compounds, make sure that the right amount of fresh air enters the house.
5. Never store or store containers containing volatile chemical compounds inside the house!
6. Never mix detergents, scale removers or disinfectants used indoors.

As a result of mixing them together, a harmful and dangerous chemical compound may be produced.

Among other chemical compounds that humans come into contact with and breathe inside the house or in closed and isolated spaces is the smoke from burning tobacco.
Studies have shown that tobacco smoke in cigarettes, hookahs or pipes contains about 7000 volatile chemical compounds!  

Insecticides are toxic compounds that are used to kill and destroy all kinds of insects inside and around the house.
Of course, the poisons used to kill rodents such as mice are also among these chemical compounds.
Insecticides are often available in the form of sprays, liquids, pens impregnated with insecticide compounds, powders, crystalline particles, or evaporable tablets.
Studies have shown that a high percentage of families in Iran and other countries in the world use at least one insecticide or pesticide indoors.
Normally contact with these insecticides is through direct inhalation of these compounds or inhalation of dust contaminated with these toxins and chemical compounds.

1. Use non-chemical methods to control insects and pests as much as possible.
2. Get insecticides and pesticides from reliable and standard manufacturing companies.
3. The amount of insecticides and pesticides used must be according to the instructions of the manufacturer! Never use insecticides in the house more than allowed!
4. Never store insecticides or pesticides indoors! Also, containers containing insecticides and pesticides must be kept completely closed.
5. If it is necessary to dilute solutions and liquids of insecticides and pesticides, the dilution process should be done outside the house.
6. Increase indoor ventilation when using insecticides.
7. Move plants and pets outside when using insecticides!

Nitrogen dioxide and nitrogen oxide are toxic gases that are produced and enter the indoor air due to the use of unauthorized and non-standard combustion devices (such as gas stoves or gas heaters) or as a result of improper and improper installation of combustion devices. .
These gases are also present in the smoke from burning tobacco or oil heaters.

1. Be sure to get heating devices and gas stoves from reliable and standard manufacturers!
2. Be sure to ensure the correct and standard installation of heating devices and gas stoves!
3. Use vents suitable for gas stoves to remove combustion gases!
4. Do not use the fireplace indoors as much as possible! Despite the installation of chimneys in fireplaces, the emission of combustion gases inside the house is inevitable!
5. Avoid leaving the car on in the parking lot next to the house.

Suspended particulate pollutants are complex combinations of solid (or) and liquid particles that are suspended in breathing air.
These particles are very diverse in terms of size, shape and chemical composition.
Particulate matter in the breathing air of the house often has a size of 10 micrometers or less.
These particles with this size can easily enter a person’s respiratory tract and lungs.
The origin of suspended particles in the breathing air of the house is sometimes the air outside the house, which is transported from the outside to the inside of the house due to the air flow.
In some cases, suspended particles in the indoor air have an internal origin.
Some of the internal sources of creating suspended particles in the air of the house are: 
using a gas stove while cooking, using a fireplace, lighting a candle, using non-standard gas heating devices or using oil heaters.

1. All heating devices and gas stoves and other combustion systems must be equipped with ventilation devices or chimneys!
2. When cooking, be sure to use a fan (suitable for the gas stove)!
3. It is better not to use the fireplace indoors! Despite the installation of chimneys in fireplaces, the release of suspended particulate pollutants inside the interior of the house is inevitable!
4. Regularly and regularly check the filters of the air conditioners and make sure that they are healthy and clean.
5. Avoid opening windows and doors related to the outside of the house as much as possible on polluted days!
