Indoor decoration harmful substances such as formaldehyde, benzene, ammonia and other standard is an important cause of indoor air pollution, a serious threat to human health. Among them, formaldehyde, the highest indoor air pollution factors of the first.
What is formaldehyde?
Formaldehyde has no color, but has a pungent odor, highly volatile at room temperature, the spread of ability is good. Known for immersion of biological specimens of formalin, is Formaldehyde Solution.
Formaldehyde in the end how toxic?
In addition to the damage to liver and kidney function, the carcinogenic formaldehyde is also beyond doubt.
WHO (WHO) identified as carcinogenic and toxic substances, formaldehyde, formaldehyde in the list of priority control of toxic chemicals in our country, ranked second.
According to the U.S. Centers for Disease Control and prevention, although formaldehyde specific cause of malignant tumor dose is currently no clear scientific research data, but if long-term exposure to formaldehyde, even low doses, risk of cancer will also rose sharply.
Moreover, the formaldehyde for children, pregnant women and the elderly, the impact will be greater.
Formaldehyde lurking in our side?
Because the price is low, formaldehyde is widely used in industry, resulting in a lot of formaldehyde in our lives.
Bear the brunt of the decoration materials and furniture to become the main source of indoor formaldehyde pollution, especially the newly renovated house and buy new furniture, formaldehyde content is indeed relatively high. At the same time, we are usually more common in some industrial products such as preservatives, carpet, paint, cured products, etc., but also contain formaldehyde.
In fact, a lot of relevant industry practitioners will have exposure to the potential risk of formaldehyde, most likely exposed to formaldehyde with formaldehyde as raw material manufacturing industry, workers are not only living high concentrations of formaldehyde in the air, the skin is exposed to liquid formaldehyde.
In addition and some can be exposed to formaldehyde profession, such as departures, medical personnel, research room making specimens of teachers and students, clothing or furniture factory workers.
Formaldehyde how to enter our body?
1 inhalation of respiratory tract
When you breathe in the air containing formaldehyde, most of the formaldehyde will be dissolved in the airway cells and exhaled in vitro, however, when the formaldehyde concentration is high, it will enter the blood through the respiratory tract.
2 intake of digestive tract
Formaldehyde in food or water can quickly enter the body through the digestive tract.
3 skin contact
Exposure to liquid formaldehyde, a small amount of formaldehyde will penetrate the body through the skin.
Formaldehyde rampant, how can we hide?
1 no smoking
No matter what brand of tobacco, all contain formaldehyde. Only quit smoking, in order to prevent the damage of this part of formaldehyde. And the damage is not a simple for smokers, in the indoor smoking, also let a room of people suffering from formaldehyde pollution.
2 keep the room ventilation
Indoor building materials, furniture, the release of formaldehyde in the air, more ventilation can reduce the formaldehyde content. Home as little as possible to suppress the wood. When the formaldehyde content is high, more windows or exhaust fan to make the house air circulation, this is a very simple and effective way. However, ventilation is not a panacea, formaldehyde release cycle is longer, generally three years to 15 years, and therefore attempts to ventilation for several months to completely eliminate the indoor formaldehyde pollution is not realistic, and this requires us in the choice of decoration materials when Mo cheap, choose normal manufacturer, as far as possible to reduce the concentration of indoor formaldehyde, once measurement of indoor formaldehyde concentration below state of 0.08 mg / m3, you can be assured to stay.
3 new clothes to be over water
Some durable press fabrics, emit formaldehyde and formaldehyde, but easily solution in water, wear new clothes before washing it again can reduce the release of formaldehyde durable press fabric, to remove residual most of the formaldehyde in clothing, thereby reducing the risk of formaldehyde exposure.
The Green League Environmental Protection Technology Co., Ltd. was established in 2003, specializing in providing Foshan in addition to formaldehyde, photocatalyst in Foshan, Foshan in addition to smell, Foshan in addition to the paint fumes, Foshan houses in addition to taste, Foshan air purification, Foshan formaldehyde detection service is national the earliest in the photocatalyst, in addition to formaldehyde, decoration pollution control of large enterprises is the first master photocatalyst in addition to formaldehyde in addition to pollution of core technology and application of high-tech enterprises, environmental protection industry association member units.
