Today we are increasingly talking about a healthy lifestyle and quality of life, but have you ever thought about the quality of air we breathe? According to research 90% of us spend most of our time indoors. If you count the time we spend at home, office, car, etc., then you will realize how close this reality is. The “sick building” syndrome These practices of building managers were without any sense of consequences. So, suddenly, “sick building syndrome” came up as a term. “Sick building syndrome” has been officially recognized by the World Health Organization since 1982. The first indications to identify the syndrome are high levels of dioxide of carbon (the most common bio-waste) emitted resulted in residents realizing that the air was “hot and fiery”. The second indicator was the increasing humidity inside the building which led to condensation especially in the building cavities. This concentration of moisture leads to mold formation.
Mold has a lot and a negative effect on our health. In particular, the mold began to cause irritation to the eyes, nose, throat and skin. In the end, “unhealthy building” syndrome began to be very evident from the smell of the emission of chemical gases. chemicals rather than biological origin. This lack of understanding led to a period of at least 40 years, persistence with VOCs and the emission of these chemicals into the air. This perception is partly due to the fact that at that time VOCs were very high on the agenda of environmental organizations. Except for very “aggressive” chemicals such as methanol or formaldehyde emitted from the resin of the alcise plate and nitrogen dioxide emitted by gas stoves. and stoves. Other than these two elements, no other volatile organic association is directly linked to adverse health effects. . So why wait for any direct effects on our health? Anyway, the headlines “Does Your Carpet Die?” They are more appealing to the public than “Please remember to open your windows where and where.” Semi-volatile organic compoundsIn the mid-2000s, public attention focused on semi-volatile organic compounds. This shift of attention was the result of endocrine disrupting chemicals. Before one had not made the connection about indoor air quality since no one could perceive that a compound with such low volatility could be absorbed in significant quantities. Now it has been shown that the powder remains in the materials that contain these elements (eg Vinyl flooring and the like) absorb all chemicals and then re-expel air. So they end up in our respiratory system.A study conducted by Bornehag et al. (2005) showed a link with phthalates (compounds widely used in plastics) and the occurrence of asthma. our home. Since there are not many homes that contain vinyl flooring or seat covers, this connection was initially treated with hesitation by scientists. However, interviews with different families showed a significant increase in specific products containing phthalates. Most likely, these products are mainly used to clean vinyl surfaces. And if it is worse to open the window? The traditional way to improve poor indoor air quality is to increase air ventilation to clean contaminants. Good ventilation works positively to clean volatile organic substances and bio-waste like CO 2 and odor.But what do we do if outside air is worse than indoor air? This is a very common problem in urban centers especially prior to the introduction of environmental regulations. Other sources of contamination arise from the burning of various materials, for example when waste is burned from the ground, especially in the regions of Southeast Asia. In addition, activities such as burning grass and pollen from plants can cause asthma. In the above cases, the pollution coming from outside our home goes against our efforts to maintain good interior quality and pollution outside our home. While technology, to minimize particulate pollution outside our home, is very expensive and not too widespread. Normally, we have to invest in housing at least technology for hospitals where asthma patients require shelter and treatment.We believe that the best solution for maintaining indoor air quality is fresh and clean air. While this is true, we also recognize that it has become even more difficult to find off-air quality.
