Take kindergarten as an example. Under the trusteeship system, children spend more time in kindergarten than at home. If formaldehyde exceeds the standard, the harm to children's health can be imagined.
Recently, it was reported that more than 100 children were allergic to a kindergarten in Kunming, Yunnan due to renovation problems. Ms. Qin's child had a lot of red rashes all over her body just a few days after entering the park, accompanied by symptoms of fever and nosebleeds. Because the pre-Qin lady thought that the recent hot weather was caused by the child's own heat, she was informed to go to kindergarten, only to know that it was not only her own children who had this reaction.
Later, according to the air quality report issued by the environmental protection testing agency and the opinions given by relevant experts, the biggest reason why children have this problem is that the quality of decoration materials used in kindergartens is uneven, not all of them are environmentally friendly materials. As a result, a large number of harmful gases such as formaldehyde and benzene series were deposited in classrooms and dormitories in kindergartens, leading to formaldehyde poisoning in children.
Here, in order to attract the attention of parents, we have to emphasize how harmful formaldehyde is to children's health.
Children are young, with low resistance and immunity, and are the most vulnerable groups to formaldehyde. When does the formaldehyde concentration in indoor air reach 0. 10㎎/m? Children will have mild asthma and skin allergies, just like children in this kindergarten. At 0.2㎎/m? —0.3㎎/m？ Sometimes there will be obvious irritation, tears in eyes, foreign body sensation in throat and coughing all the time. Long-term contact will lead to memory loss, low immunity, easy to get sick, repeated fever and cough. It can even lead to leukemia. At present, more than half of the data of childhood leukemia published by medical institutions are related to excessive formaldehyde in indoor air.
In order to prevent similar incidents from happening again, in addition to formaldehyde reminds parents that when choosing a kindergarten, we can roughly judge whether the air quality of the kindergarten is up to standard from these points.
1.？ When choosing a kindergarten, you must ask the garden to issue an air quality test report with C MA logo, which contains specific indicators of harmful volatiles in indoor air. CMA report is an official endorsement, which has legal effect and is basically not fraudulent.
2.？ Take the children to kindergarten and feel for yourself. If there is obvious pungent smell in the classroom, it is basically that formaldehyde exceeds the standard.
Ask the children in the same class if they have similar skin allergies and often catch a cold and have a fever. If there is, please pay attention to it in time, because the harm of formaldehyde to human body is a slow process, which is directly related to human resistance.
