Heilongjiang: 90% of the newly decorated houses have unqualified air quality

recently, the reporter learned from Heilongjiang environmental monitoring center that more than 90% of the newly decorated houses have unqualified air quality. Insiders remind that the pollution concentration of formaldehyde in summer is significantly higher than that in other seasons. Citizens should always be ventilated after decoration and do not move in immediately

with the enhancement of people's awareness of environmental protection, Harbin citizens pay more and more attention to the detection of pollution after home decoration. According to the test results of the provincial environmental monitoring center station for many years, most of the pollution sources come from over standard ceramics, marbles, chemical materials, organic solvents, boards and furniture containing formaldehyde with radioactive pollution. Among them, indoor air pollution is mostly caused by toxic gases or radioactive materials

according to sun Jiang, director of Heilongjiang environmental monitoring center, formaldehyde usually exists in the interlayer of wood-based panels as a raw material of adhesives, which is not volatile and usually takes 8 to 15 years to volatilize. The pollution concentration of formaldehyde in summer is significantly higher than that in other seasons. A simple way to deal with formaldehyde is ventilation

director Sun reminded citizens to choose simple decoration as much as possible, choose high-quality healthy and environmental protection building materials that meet national standards, and avoid using decoration materials with low prices. It is not suitable to move in immediately after decoration. You should open the window every day for ventilation. Generally, you can only move in a few months after decoration. After moving in, you should also strengthen ventilation to minimize indoor pollution. If citizens outsource decoration, they should sign a contract with the decoration company to ensure air quality
