New house moved in the new year to prevent home-installed pollution

As the Chinese New Year approaches, many families have chosen the lucky day and are anxious to decorate the house. Fortunately, in the new home, there is an auspicious New Year. There are no shortages of owners who have just finished their renovations and can't wait to live in. They do not know the potential killers in the new house.

A few days ago, Ms. Huang, who lives in downtown Jinhua, just renovated her house and wanted to move into a new house for the New Year. However, the door was just smoked. Later, she invited the indoor environmental monitoring department to carry out indoor air testing on the new home, only to find that the home is just like a "poison room." Formaldehyde, benzene series, and total volatile organic compounds (TVOCs) exceed the national indoor air quality standards, among which formaldehyde pollution is the most serious.

According to a person familiar with the Indoor Air Monitoring Center, formaldehyde is a colorless, easily soluble, irritating gas that is harmful to human health. Particleboards, density boards, plywood and other man-made boards and adhesives are the main sources of formaldehyde in the air. Benzene, toluene, xylene, and total volatile organics (TVOC) are mainly derived from paints and coatings. Formaldehyde can be absorbed through the respiratory tract. The harm to the human body is long-term, latent, and hidden. It can cause people with tears, pharyngeal discomfort, coughing, sneezing, and other symptoms of the respiratory system. It can also cause people with allergies. Some allergic reactions occur. It may feel itchy and some skin rashes may cause nasal and nasopharyngeal cancer.

According to reports, formaldehyde, benzene and other harmful substances in large-core boards, composite flooring, furniture, paints, and coatings are volatile, and some naturally volatilize for a period of 3 to 15 years. Ventilation is good, it is very easy to pollute indoor air, causing excessive concentration of harmful substances. Especially in winter, the doors and windows (doors and windows renovation renderings) are tight, the indoor air circulation is poor, and the room temperature is relatively high. The indoor pollutants will be released and accumulate at an accelerating rate. In addition, indoor pollution will damage the human immune system and nervous system. Older people and children with relatively weak constitution are more difficult to bear, and indoor pollution is much more harmful than other seasons. Experts reminded consumers that after the house is renovated, do not rush to stay. At least one or two months of vacant ventilation is required. It is advisable for qualified families to have an air quality test at the qualified indoor air testing center after the renovation is completed. If the hazardous substance is seriously exceeded, it must be targeted for rectification and rework after the cause has been identified until it reaches the standard to prevent hidden dangers.
