According to reports, Nanjing's 2-year-old baby Shu Shu was taken by his parents to a newly renovated house of his relatives. He had a fever after living for 5 days, and his family didn't care about it after the cure. They lived together for 15 days. When the parents received the child, they found that the child was covered with bruises and sent to the hospital for examination. He even got acute lymphoblastic leukemia!
After inspection, the culprit turned out to be formaldehyde. When people were shocked, they would ask: How can formaldehyde cause leukemia quickly? In this regard, Director Chen of the Provincial Hospital Blood Center explained, "Formaldehyde has been identified by the World Health Organization as a carcinogen and teratogenic substance, and it is also one of the potential strong mutagens. Because children's bones and blood systems are not perfect, formaldehyde Waiting for the decoration pollution will be extremely fatal to them. "
Leukemia, lung cancer, nasopharyngeal cancer, infant malformations ... These cases are caused by decoration pollution, and we are all told that it is imperative to remove formaldehyde in new houses. Is there any way to remove formaldehyde quickly and safely? 吴教授 。 Recently, with these questions, the reporter specially interviewed Professor Wu , a technical consultant of the Building Environment Inspection Center of Tsinghua University in Beijing, and research on indoor air pollution control in China .
First, the plant's ability to remove formaldehyde is inadequate
The professor told us that the absorption of formaldehyde by plants is extremely small and limited. Even if hundreds of spider plants are placed in a 100 square meter living room, the amount of formaldehyde absorbed is less than 5%, that is, 95% of the formaldehyde is free in the air. Therefore, it is not possible to completely rely on plants to remove formaldehyde, and some white vinegar fumigation, grapefruit peel, onion slices and other methods are even more undesirable. These can only play a role in masking the odor, which is completely concealed.
2. Limited adsorption of activated carbon, easily causing secondary pollution
Based on extensive advertising in recent years, many people think that dozens or hundreds of packages of activated carbon can remove formaldehyde well. However, CCTV "News Live Room" also conducted investigations, confirming that the removal of formaldehyde from ordinary activated carbon is not reliable. Professor Wu told us that the effect of activated carbon in removing formaldehyde has been exaggerated, which has misled many consumers. "It is undeniable that activated carbon is a good adsorbent, but these activated carbons on the Internet have too large pores and have not been activated at high temperatures. In addition to limited formaldehyde and easy to saturate, they will release formaldehyde again and cause secondary pollution.
Photocatalyst is the most effective research
Photocatalyst, photocatalyst is a general term for a photo-semiconductor material with photocatalytic function represented by nano-sized titanium dioxide. It is coated on the surface of a substrate and produces a strong catalytic degradation function under the action of ultraviolet light: it can effectively degrade air Poisonous and harmful gases; can effectively kill a variety of bacteria, and can decompose and harmless toxins released by bacteria or fungi; meanwhile, it also has functions such as removing formaldehyde, deodorizing, antifouling, and purifying air.
For the health and safety of you and your family, please take a proper look at the pollution problem after the decoration of the house and avoid unnecessary injuries. ，刻不容缓。 Remove formaldehyde without delay.
