Yesterday, the smog continued to cover the capital, and many children wore masks for adults.

The National Standard for the Technical Specifications of Daily Protective Masks has been released recently and will be officially implemented on November 1. This is the first national standard for civil protective masks in China, but the standard is clearly labeled as “not suitable for children's masks”. . According to a survey conducted by the Beijing Youth Daily, children's masks have a large share in the Beijing market. There are many brands with different prices, but there is no production standard, and most of them are smaller versions of the population cover. Experts involved in drafting standards revealed that the standard for children's masks was not included in the new regulations, mainly because children's physical differences were relatively large, and data collection was difficult. The next step would be to consider.

New masks are divided into four levels

Child standards are not included

Every child's health is more susceptible to smog, and many parents will wear them even if they don't have the habit of wearing a mask. Ms. Wang’s daughter just entered the first grade of primary school this year, but the mask is no stranger to her and other small classmates. In the past few days, almost every student has worn a variety of masks. "Cotton, with a breathing valve is more common, and some parents wear a normal disposable non-woven mask for children."

Feng Guofang, director of the Department of Otorhinolaryngology, Beijing Eastern District Children's Hospital, said that from a clinical point of view, children's bronchitis, bronchitis, and allergic rhinitis have an upward trend in smog days. Feng Guofang introduced that in addition to the well-known PM2.5, there are even smaller particles than PM0.5, which can enter the trachea, bronchi, and alveoli with air. "Children are wearing skin masks, including airways, nasal mucosa, throat mucosa and tracheal intima, alveolar surface and other parts are more delicate, more vulnerable to injury, if you are wearing outdoor masks."

From November 1st, the national standard "Technical Specifications for Daily Protective Masks" will be officially implemented. This is the first national standard for civil protective masks in China. According to the "Technical Specifications for Daily Protective Masks", the protection levels are classified into D-class, C-class, B-class and A-class according to air pollution conditions, which are applicable to moderate and below pollution, severe and below pollution, serious and The following pollution and serious pollution, the corresponding protective effects of each level are not less than 65%, 75%, 85%, 90%.

However, as smog weather frequently occurs, the masks of children who are most affected by smog are not included in the newly revised standards. As a person who is more susceptible to haze, the standard is clearly “not applicable to children's masks”.

survey

Children's anti-mite masks are mostly for adults.

The simplest way to protect against smog is to wear a mask. Nowadays, children's masks also occupy the half mask market. Many supermarkets, drugstores, pharmacy mask counters, and children's masks are placed in conspicuous positions. Children's masks have various brands and different styles. The prices of common domestic brands range from a dozen yuan to tens of yuan, and the imported brand single masks cost hundreds of yuan.

Yesterday, the reporter of Beiqing Daily came to a large supermarket in Qingnian Road. The masks were displayed separately on a shelf. The children's masks were divided into two brands, Ito and Green Shield, which were protective masks for the filter and once. Sexual non-woven masks are written to protect PM2.5. Ito's mask is S, indicating "suitable for children aged 5-12", and Green Shield includes XS and S, which are suitable for children aged 3-6 and 7-12, and a green shield child. Non-woven masks are all-in-one. The reporter of Beiqing Daily found that the masks of the two brands all indicated the implementation standards, product types, basic safety technical specifications, shelf life and other information on the product packaging, but did not find the "protection effect level". Another S-type children's mask imported from Taiwan's imported drugstores is marked with the protection level "KN95". The masks of the three brands range in price from 15 yuan to 30 yuan. On the Internet, there are two imported brands of children's masks, totobobo and Vogmask, which are priced at one hundred yuan.

A salesman of a well-known domestic mask manufacturer told Beiqing Daily that the masks of children's masks and adults are exactly the same, but the "reduced version" of adults is to take care of children's faces in order to achieve better sealing. And fit. However, the reporter of Beiqing Daily unveiled a mask of several domestic brands. Although it is a mask for children, it is also possible for adults to wear it, and several masks for changing filters are worn on the faces of adults. Can't completely fit the face, there are still gaps in the cheeks.

Ms. Liu also bought children's masks for children who had just gone to kindergarten, but after trying three or four, they gave up because of the inappropriate size. "For a 5-year-old child, even a child's model is still too big. 3M has a minimum respiratory valve mask, which is a bit suffocating after the child tightens the elastic band." Ms. Liu told the reporters because Experts say that if the mask is not well sealed, the protective effect is not ideal, so it is no longer necessary to wear a mask for the child. If the haze is too serious, rest directly at home.

dialogue

Children are not included in the new rules for physical differences, big data collection is difficult

Dialogue: the lead drafter of the first national standard for civil masks, and Zhao Yuyu, senior engineer of China Industrial Textile Industry Association

Beiqing Daily: The Technical Specifications for Daily Protective Masks clearly states that the standard “does not apply to children's masks”. Why exclude "child masks" from the national standard?

Zhao Yuyu: This standard does not cover protective masks for children, mainly because the physical characteristics of children and adolescents in China are quite different at this stage. The accumulation of experimental data for this special group of children needs to be improved, such as analyzing the influence of respiratory resistance on children's growth. Medical data, etc.

Beiqing Daily: There are many nominal "children's masks" on the market. The material is the same as the population cover. It can be said to be a miniature version of the population cover. Is this production standard scientific?

Zhao Yuyu: The real children's masks should not be a miniature version of the population cover. At present, there is no uniform standard for children's masks in some countries. Some manufacturers have relatively simple internal standards, and there are few projects covered. Strictly speaking, children's masks cannot be used to replace children's masks. The next step is to consider the criteria for developing a mask for children. At present, relevant departments are conducting in-depth research and efforts to promote the standardization of daily protective masks suitable for children. The main difficulty is that some technical information is not perfect, and the monitoring data for the use of children's masks is not complete.

Beiqing Daily: According to the “Technical Specifications for Daily Protective Masks” to be implemented, which masks on the market will be eliminated?

Zhao Yuyu: Actually, in the "Technical Specifications for Daily Protective Masks", there is no singularity for the fabrics and filter materials of masks, and the key point is to clarify the standards for protective effectiveness. This is because if the material is too limited, it is not conducive to the innovative development of mask technology. That is to say, this standard does not target a certain product or a certain type on the basis of satisfying the needs of consumers, but provides a technical specification for the enterprise to more accurately select a suitable mask for the consumer. For example, there are no breathing valves, some masks plus breathing valves to reduce respiratory resistance, some are not, but with the advancement of technology, masks without breathing valves can also have a good protective effect based on low respiratory resistance. Therefore, no constraints or restrictions are imposed on this aspect.

enterprise

Some children's products

The material is not that thick

Yesterday, Zhao Danqing, the chairman of the domestic well-known mask brand “Green Shield”, and the chairman of Shanghai Xingnuo Kanglun Fiber Technology Co., Ltd., said in an interview with Beiqing Daily that the Green Shield children’s masks were implemented by the company’s “antibacterial”. The standard for flood control is that the material is not so thick and the respiratory resistance is relatively small compared to the same series of population cover. “The material is not thick, it does not mean that the filtration effect is poor, and the comprehensive mask shape can meet the filtration requirements.”

For the new standard to be implemented, Zhao Danqing said that some products of the Green Shield mask will implement the national standard, and some products will continue to implement the enterprise standard. “Because our enterprise product standards have increased the antibacterial and anti-influenza effects on the basis of the national standard, Fine results, so some of the company's standard products will be retained." In addition, all masks will not increase in price due to the implementation of the new standard.
