Shanghai quality and technical supervision Bureau: Super 60% mask filters is not optimal

Shanghai quality and technical supervision Bureau: Super 60% mask filtering ineffective mask | | | haze haze masks _ prevention news

Staff writer, Beijing, March 19 (reporters Wang Quan and Chen Xiao and and Li Lin)-anti-haze haze weather fire the mask. "PM2.5", "isolation of dust", "Anti-Haze" ... ... Nominal masks with various protection features a variety on the market, the effect of what has been a consumer of wrenching problems.


On March 17, the Shanghai Municipal Bureau of quality and technical supervision issued a market in Shanghai face mask product safety risk monitoring results. Results show that ultra-filter 60% product is not optimal. "Green Shield", "Itoh の yield" and other anti-haze masks selling brands are listed.


The monitoring standard is used in GB2626-2006 of the respiratory protective equipment vacuum filtering of particulate respirators, GB15979-2002 under the hygienic standard for disposable sanitary products, GB18401-2010 the State of basic safety technical norm for textile products, and other national standards. Identification of the masks, filter efficiency, microbiological indicators (total number of colonies of bacteria, coliform bacteria, pathogenic Pyogenic bacteria and fungi colony), textile technical requirements (formaldehyde carcinogenic aromatic amine dyes, pH value, and can be broken down) project was launched.


Among them, the filtration efficiency of greatest public concern. This indicator refers to the provisions of the conditions, the percentage masks for particulate matter in the air filter. It directly reflects a particulate mask effect.


But the results showed that samples of the 38 lots of masks, filtration efficiency measured value is lower than the standard 24 batches face masks (GB2626-2006) 90% set out minimum requirements, 1 mask filtration efficiency measured values below the requirements of express 95%; 21 batches of product identification without filtration rating; 6 batches without product performance standards.


Filter efficiency below 90% in 24 batches of products, including in online sales of "Green Shield PM2.5" mask. Test, produced by Shanghai nuokang aramid fiber green shield PM2.5 non-woven masks (adult), Green Shield PM2.5 antibacterium haze masks (thin and breathable), Green Shield antibacterial anti-haze mask filtration efficiency measured PM2.5, and 64.3%, and 10.3%, respectively.


In this regard, Shanghai XING nuo Kang aramid fiber Technology Marketing Manager Guan Lijun said the company's products are manufactured in strict accordance with the standards developed within an enterprise. Monitoring standards that are used in GB2626-2006, in her view, "which was enacted against dust masks for industrial use, and do not apply to civilian mask. "She stressed that XING nuo Hong LUN mask using the standard has been in the local quality and technical supervision Department for the record.


The China Youth daily reporter, there is currently no mask for civilian national and industry standards. Masks production enterprises in accordance with their respective internal standards.


Bede's hygiene products produced by the company, Xuzhou の yield of PM2.5TM protective masks named Ito (non-woven fabric), Ito の yield of PM2.5TM protective masks filter efficiency only measured values 17%, 10.7%, respectively.


Bede's in charge of marketing also contested the above monitoring results. In his view, different detection standards, displaying results are noticeable disparities. Bede is currently not received any notification concerning their products off the shelves or the relevant management.


In addition, the PH values exceeding the monitoring report also shows that many products exist, without filtration grade problems.


E-commerce website is one of the anti-haze masks sales main channels. "First, shop the online supermarket" staff told China Youth daily reporter, any irregularities, defects of products, they will be dealt with off the shelf. At present, the Shanghai Bureau of quality and technical supervision announced this monitoring report, "first, shop the online supermarket" related departments have begun to investigate and deal with.


Jingdong Mall also said that selling masks already on the platform verification, including its own sales channels and third party sales channels. Once discovered substandard quality products, will also be off the shelves. At the same time, Jing dong will also work closely with the relevant manufacturer, sectoral cooperation, strive to maximize the protection of consumer interests.

上海质监局:超6成口罩产品过滤效果不佳|口罩|防霾口罩|雾霾_新闻资讯

  本报北京3月19日电(实习生汪泉 陈骁 记者李林) 雾霾天气带火了防霾口罩。“PM2.5防护”、“隔离粉尘”、“防霾”……市面上标称具有各种防护功能的口罩五花八门,其效果到底如何,一直是消费者揪心的问题。


  3月17日,上海市质量技术监督局发布了一份在沪市场销售的口罩产品安全风险监测结果。结果显示,超6成产品过滤效果不佳。“绿盾”、“伊藤の良品”等国内热销防霾口罩品牌均榜上有名。


  该监测采用的标准是GB2626-2006《呼吸防护用品 自吸过滤式防颗粒物呼吸器》、GB15979-2002《一次性使用卫生用品卫生标准》、GB18401-2010《国家纺织产品基本安全技术规范》等国家标准。针对口罩的标识、过滤效率、微生物指标(细菌菌落总数、大肠菌群、致病性化脓菌和真菌菌落总数)、纺织品安全技术要求(甲醛含量、pH值和可分解致癌芳香胺染料)等项目展开。


  其中,过滤效率最受民众关注。这一指标是指在规定的条件下,口罩对空气中颗粒物滤除的百分数。它的高低直接反映了口罩防颗粒物的效果好坏。


  但结果显示,抽检的38个批次口罩产品中,24批次口罩的过滤效率实测值低于标准(GB2626-2006)中规定的90%最低要求;1批次口罩的过滤效率实测值低于明示95%的要求;21批次产品标识中未标注滤料等级;6批次未标注产品的执行标准。


  过滤效率低于90%的24批次产品中,就包括在各大网店销售火爆的“绿盾PM2.5”口罩。经测,上海兴诺康纶纤维科技有限公司生产的绿盾PM2.5无纺口罩(成人型)、绿盾PM2.5抗菌防霾口罩(轻薄透气型)、绿盾PM2.5抗菌防霾口罩过滤效率实测值分别为64.3%、86.3%、10.3%。


  对此,上海兴诺康纶纤维科技有限公司市场部经理管丽君表示,该公司产品均严格按照企业内部制定的标准生产。对监测中使用的标准GB2626-2006,她认为,“该标准是针对工业用防尘口罩制定,并不适用于民用口罩。”她同时强调,兴诺康纶生产口罩使用的标准已经在当地质监部门备案。


  经中国青年报记者了解,我国目前尚无民用口罩的国家、行业通行标准。口罩企业多按照各自内部标准进行生产。


  徐州贝德氏卫生用品有限公司生产的名为伊藤の良品PM2.5TM防护口罩(无纺布)、伊藤の良品PM2.5TM防护口罩过滤效率实测值仅分别为17%、10.7%。


  贝德氏市场部负责人也对上述监测结果提出异议。他认为,在不同的检测标准下,显示的产品结果差别十分明显。贝德氏目前没有接到任何关于其产品下架或相关处理的通知。


  另外,该监测报告还显示许多产品存在PH值超标、未标注滤料等级的问题。


  电子商务网站是防霾口罩销售的一个主要渠道。“一号店网上超市”工作人员告诉中国青年报记者,凡是违规、有质量缺陷的产品,他们会一律作下架处理。目前,针对上海质监局公布的这份监测报告,“一号店网上超市”相关部门已经开始着手调查、处理。


  京东商城也表示,对平台上在售的口罩产品已经开始核查,包括自有销售渠道和第三方销售渠道。一经发现质量不达标的产品,也将下架。同时,京东还将积极与相关厂家、部门配合,力争最大程度保障消费者的利益。
