| Event Details:
Most recently, Mr. Zhang's new house in Jiangbei renovated, is happily move into a new plan, but by his colleagues to dissuade Ms. Lin: "A few months before put it, the smell dissipated and other decoration materials and then move in, health to put the first one ah. "Zhang finally listened to the staff suggestions on a regular basis to the new house to open doors and windows ventilation.
In recent years, home improvement environment gradually been public concern about interior decoration and household pollution complaints become a hot topic in environmental circles. Pediatrician pointed out that the pursuit of the surface decoration of the magnificent and decoration materials caused by improper use of indoor pollution is the main cause of health effects, especially in children suffering from leukemia and led to the increased risk of respiratory tract infection.
Old children suffer first home improvement pollution
Zhao aunt to take care of grandchildren, moved to the south bank of his son's new house to live, but to move in. Before long, Zhao aunt began to cough constantly. When daughter leave, she will return to the lower corner of the old house to live a few days. "In the new house, especially the throat discomfort, always coughing." Zhao aunt said, back to the old house, the symptoms basically disappeared.
But the task is urgent to take care of grandchildren, she was forced to live in his son's new house. Cough becoming increasingly obvious these days, she went to the doctor in. Dr. Zhao aunt's house that was renovated recently, the proposed multi-outdoor walk Zhao aunt, a breath of fresh air, conditions permitting, on the first move out of the house just renovated some time.
General Manager Yan Xiaobo Ji introduced as decoration, although the interior design company uses environmentally friendly materials, but are not environmentally friendly material does not contain any formaldehyde, but only low levels of formaldehyde. And young children, pregnant women, the elderly are particularly sensitive to formaldehyde, Zhao aunt live in newly renovated house will add to her respiratory condition.
According to pediatric doctors, birth defect rate continues to rise, in addition to family genetics, viral infections, but also, and interior decoration, the long-term exposure to equipment contaminated with radiation, has a lot of factors.
Latest statistics show that children aged 0 to 14 as high risk of leukemia, and environmental pollution, especially indoor pollution is an important incentive. China Indoor Environment Committee, 5 years 6000 statistics home indoor environment test results showed that married and mother-child family room exceeded the 70% test, a child health problem families exceeded 90% of the indoor environment. State Children's Health institutions in the history of research in child leukemia found: nearly 90% of children at home have been renovated recently, and many children at home or luxury decoration.
The health hazards of formaldehyde on how much it? Environmental experts, that when the indoor concentration of 0.1 mg / cubic meter (PPM) when there is smell; 0.5PPM tears can cause irritation of the eyes; 0.6PPM cause throat pain when; high concentrations can cause further nausea, vomiting, coughing, chest tightness, asthma or emphysema; When the air reaches 230PPM can immediately lead to death. Long-term inhalation of low doses of formaldehyde can cause chronic respiratory diseases, conjunctivitis and other chronic diseases.
Substandard building materials is the culprit
"Substandard building materials is the cause of pollution in the first fitting." Yan Xiaobo introduction, decoration pollution caused by many reasons, including substandard materials, improper indoor decoration methods and people's awareness of environmental testing has not yet formed, of which the substandard building materials on the human body most harmful.
Statistics show that modern indoor air than 300 kinds of volatile organic compounds, which easily cause injury or even alone, there are 20 kinds of cancer. Pediatrician, said the main building and decorative materials are potential sources of indoor air, and paint furniture, paint, synthetic fiber board is a major indoor pollutants.
Many owners will be able to avoid that the use of environmentally friendly building materials decoration pollution hazards, in fact, this is a big misunderstanding, because the extensive use of environmentally friendly building materials, the formation of formaldehyde accumulated pollution, green building materials can not avoid the zero-formaldehyde, heavy use of formaldehyde in building materials can be accumulated to excessive levels.
Yan Xiaobo said that even if environmental standards are adopted on the floor, the decoration plate will still be excessive, because the additive effect caused by the "several such environmentally friendly materials in the room, superimposed with the release of hazardous substances, formaldehyde, benzene and other harmful substances emissions have increased. so even if a single product standards, pollution will still be excessive interior decoration. "
In addition, the light taking into account the decorative material is standard, but ignores the glue used during the renovation, often these high levels of formaldehyde glue. Does not rule out some known environmental standards of products, and not done a real standard.
By smell the smell of pollution is not accurate to judge
A considerable part of the family is not the pollution in the decoration of children seriously, ignoring the environment, a lot of people buy cheap decoration materials. Yan Xiaobo, said all the renovation is finished, the environmental monitoring should be done, but this last part is often omitted, and some families approach will open the window "up taste," or sometimes just direct placement.
Pediatricians advise, smell the smell alone is not reliable to determine the pollution of the beam, does not mean no pollution, no odor, poisonous gas, pungent smell of formaldehyde, radon on the colorless and odorless. "It takes a professional environmental monitoring, and harmful is formaldehyde, benzene, ammonia and radon, etc. If the fitting is not well controlled, high concentrations of formaldehyde in inhalation, the respiratory tract irritation may be severe."
Yan Xiaobo said decorative materials containing formaldehyde and sometimes volatile period can be up to 7 years, moved into the new house proposed to do prior to environmental monitoring, looking for professional corporate governance in addition to formaldehyde, and formaldehyde at home, get rid of some of the items placed on "Increasing indoor ventilation is ventilation frequency to reduce indoor air pollution, the best air time for each day from 6 am to 11 pm, you can plant some flowers in the room raised to aloe, spider plants, cactus, ivy, chrysanthemum, rose, rhododendron as the best, it is best done recapture control of air plants.
