Unhealthy Indoor Air Quality (IAQ) impacts the health of those who live there. It could cause the nose, throat, and nasal irritation, headaches, and allergies. Long-term exposure can exacerbate respiratory conditions and can result in heart disease and cancer.
The vast majority of contaminants that decrease IAQ include paints, furniture and cleaning products. Making use of low-emission building products can help reduce these harmful pollutants.
Organic Volatile Compounds
VOCs are emitted into the air from many everyday products and construction materials. They are in many paints, perfumes, solvents and even some cleaning products. They can also be part of the kerosene or combustion by wood stoves. VOCs can build up inside the house due to cigarette smoking, the use of cleaning products and paint, as well being infiltrated from outside. Concentrations of indoor VOC that are too high can cause the’sick-building syndrome’.
VOCs from the outdoors are a major source of ground-level ozone that is the main ingredient in photochemical pollutant. VOCs are controlled by the EPA to ensure that they do not react with light and nitrogen oxides to create ozone.
Many new construction and building substances emit VOCs like insulation floors, paints, flooring as well as adhesives. To ensure that buildings are healthy and construction, it’s essential that architects specify low-VOC products. Choosing products that are recognized and certified by Declare Label Certification, Cradle to Cradle certification, Global Green Tag certification, Lens certification, Lens certification as well as BREEAM Hea 02-credit to improve indoor air quality will help reduce VOC levels.
Formaldehyde Emissions
The use of products made from wood which contain formaldehyde could cause excessive levels of formaldehyde get released into atmosphere during the construction. The offgassing can continue for months, and is worsened by high temperatures and high humidity levels.
It is known that formaldehyde may cause cancer as well as respiratory irritation. The skin, throat, nose and eyes can also become inflamed. Formaldehyde is a precursor to various VOCs as well, and can combine with other compounds within the air and create secondary pollutants such as Trichloroethylene, acetone.
Within homes, elevated levels of formaldehyde can be found in new or recently refurbished wooden and melamine furniture or wood-based products produced with resins containing formaldehyde (such as medium density fiberboard) as well as insulating material made with urea formaldehyde foam insulation; do-it-yourself projects including painting or varnishing as well as textiles. Utilizing pressed wood labeled as CARB, ULEF, or NAF compliant will help reduce the amount of formaldehyde released.
Particulate Matter
Some of the newer building materials for example, insulation and flooring, contain asbestos, that releases toxic air when it is disturbed. These fumes can pollute the air in a building and cause allergic reactions. Exposure to particulate matter can cause respiratory or heart conditions.
Diesel-powered construction equipment is a different cause of pollution to the air da 0x4. This equipment produces huge amounts of nitrogen oxides, hydrocarbons, and carbon monoxide.
It is also essential to choose low emitting construction materials and to ensure that ventilation is working effectively to prevent contaminants from getting out of the indoor environment. The indoor pollution that is excessively high could lead to lower health and worsening of the condition, for example more hospitalizations and deaths from cardiovascular and respiratory illness. This is especially true for particular groups such as those with a disability, elderly people, and people with preexisting medical conditions. It is crucial to reduce exposure to radiation during renovations using adequate ventilation and separating working zones from other areas.
Growing Mold
They are fungi which break down biodegradable materials within our surroundings and then produce spores which consume additional nutrients in the process of growing. This never-ending process is one of the main causes of contamination within our surroundings, especially regarding mycotoxins that are produced by certain mold species, that have a greater impact on health.
There are mold spores throughout the air as well as in soil and wood used for construction. The growth of mold is dependent upon oxygen, water, as well as nutrition. A majority of furniture and building materials provide suitable nutrients, while dirt found on surfaces is another source of water.
Exposure to airborne mold spores may cause irritation to the respiratory tract, and certain individuals might experience more severe signs like fatigue or headaches. There are ways to minimize the effect of microorganisms and after construction projects through the use of materials that emit low levels of emissions, as well as ventilation designs.
