Formaldehyde removal in Jinan: The World Health Organization recently issued the Guidelines for Indoor Air Quality, which pointed out that indoor air pollution mainly comes from four aspects, namely, building materials, household appliances, heating equipment and smoke and dust generated during cooking. The main chemical pollutants in indoor air are benzene, carbon monoxide, formaldehyde and 2. Nitric oxide, radon and other nine substances. Among them, benzene ranks first, this substance widely exists in building materials, especially paint, can cause cancer; carbon monoxide ranks second, its safety standard is not more than 7 mg per cubic meter of air within 24 hours; formaldehyde ranks third, the safety standard is less than 0.1 per cubic meter of air. In milligrams, excess can damage lung function.
Comment: Although the content of these pollutants in building materials has certain standards, the indoor air will be affected by the concentration of pollutants released by these materials after home decoration. We still suggest that the newly decorated rooms should not be occupied immediately, try to stay in half a year later. Family decoration should try to choose products with environmental protection marks and furniture selection. In terms of choice, the formaldehyde content in wood-based panels is relatively high, it is better to choose furniture with high sealing degree of wood-based materials; newly bought furniture should be put for a period of time to reuse; when using the wardrobe of wood-based panels, try not to put underwear and children's clothes; in winter, windows should be opened not less than twice a day, no less than 30 minutes each time, in order to avoid aggravating pollution; Attention should be paid to regulating air humidity.http://www.jntkzl.com
