近日，有媒体报道，长期用嘴撕牛奶袋易造成重金属铅中毒，昨天，记者从超市购买7种袋装牛奶，通过北京服装学院材料检测中心和民间环保组织“自然大学”检测发现同一结果：包装中不含重金属铅、铬、汞。

recently,Media reports,Long-term use mouth ripped milk bag easy cause heavy metal lead poisoning,yesterday,Reporters from the supermarket to buy milk seven kinds of bags,Through the Beijing institute of clothing technology material testing center and folk environmental protection organization"Natural university"Testing found the same result:Package does not contain heavy metal lead/chrome/mercury.

媒体报道引网友担忧 Media reports lead users worries

　　近日有媒体报道，袋装奶携带方便，开袋即食，嘴撕牛奶袋也成了市民的习惯，有专家表示，牛奶袋的外表是用染料来印刷的字，长期用嘴咬牛奶袋的话，就容易造成重金属铅中毒。因为外包装袋的油墨里含有铅，长期口撕袋装食用影响到血液系统、肠胃系统。

Recently had the media reports,Bagged milk easy to carry,Open the bag ready,Mouth ripped milk bag has become the habit of citizens,Experts say,Milk bag appearance is to use dye to printing words,Long-term use mouth bite milk bag words,There would be a heavy metal lead poisoning.Because the bags ink contains lead,Long-term mouth ripped bagged edible affect the blood system/Gastrointestinal system.

　　还有媒体援引医生的说法，称长期口撕袋装奶确实有铅中毒的可能性，因为牛奶袋的外表是用染料来印刷的，而染料里面有铬、汞、铅等重金属，会影响到生殖系统、造血系统，以及神经系统。

There are media quoted the doctor's statement,Says long-term mouth ripped bagged milk does have the possibility of lead poisoning,Because milk bag appearance is to use dye to printing,And dye there are chrome/mercury/Heavy metals such as lead,Will affect reproductive system/Hematopoietic system,And nervous system.

　　该新闻在微博上经过加“V”用户发布和转发后，引发担忧。网友“海宁梅泽”说，儿子他们幼儿园订的牛奶没提供管子啊，都是袋装的。

The news in micro blog after add"V"After the user releases and forwarding,Cause worry.Net friend"Haining MeiZe"said,Son they kindergarten order of milk didn't provide pipe ah,Are sacked.

实验未发现包装含铅 The experiment has not found packaging lead

　　为了验证牛奶袋是否真的含重金属铅、铬、汞，记者在超市购买了7种不同品牌和包装的牛奶，包括伊利、三元、蒙牛等品牌。这7袋牛奶中，既有软塑料包装，又有硬壳包装。

In order to validate the milk bag really containing heavy metal lead/chrome/mercury,Reporter in the supermarket bought 7 different brand and packing of milk,Including Erie/Three yuan/Mengniu brand such as.This 7 bags of milk,Both soft plastic packing,And encrustation packaging.

　　随后，记者联系了北京服装学院材料检测中心和民间环保组织——自然大学。这两家机构都有专门检测材料中重金属含量的实验设备X荧光能谱仪。

then,Reporter contacted the Beijing institute of clothing technology material testing center and folk environmental protection organization, the natural university.The two agencies have special testing materials in heavy metal content of experimental equipment X fluorescence spectrometer.

　　实验人员分别用手持式X荧光能谱仪和台式X荧光能谱仪对这7袋牛奶检测，均未发现铅、铬、汞。

Experimental personnel respectively with hand-held X fluorescence spectrometer and desktop X fluorescence spectrometer to this 7 bags of milk detection,Were not found that lead/chrome/mercury.

数字打标机几乎不含铅 Digital marking machine almost contains no lead

　　对于实验结果，中国环保标准专业委员会理事、北京服装学院材料科学与工程学院副教授龚?表示，传统油墨一般会含铅，如果牛奶袋上有铅的话，很有可能在牛奶袋上的黑色日期标记上，这些标记是用油墨打上去的。不排除有的厂家使用最原始的油墨手工打标方式给牛奶袋打标的，但目前使用的数字打标机都使用的是环保油墨，几乎不含铅。

For the experimental results,China's environmental standard professional committee director/Beijing institute of clothing technology materials science and engineering college associate professor kung?said,Traditional ink will generally lead,If milk bags have lead words,Very likely in milk bag of black mark on the date,The markings are ink to play up.Don't exclude some manufacturer use the most original ink manual marking way to milk bag hit mark,But at present the use of digital marking machine use is environmental printing ink,Almost contains no lead.

　　龚?建议消费者购买正规品牌的牛奶，此外，消费者在饮用袋装奶时，不要用嘴在颜色鲜艳的地方撕。虽然牛奶袋不含铅，但不排除含有其他有害物质。建议消费者使用剪刀剪开包装，将牛奶倒入杯中，或者用吸管。

kung?Suggest that consumers buy regular brand of milk,In addition,Consumer is when drinking milk bags,Don't use mouth in color bright place tore.Although milk bag contains no lead,But not eliminate contains other harmful substances.Suggest that consumers use the scissors packaging,The milk into a cup,Or use a straw.

　　7袋样品包装不含铅、铬、汞 7 bag samples package contains no lead/chrome/mercury

　　实验目的：测试牛奶袋是否真的含重金属铅、铬、汞

The experiment purpose:Test milk bag really containing heavy metal lead/chrome/mercury

　　实验过程：记者从超市购买7种不同品牌和包装的牛奶，包括伊利纯牛奶、三元核桃花生牛奶、伊利谷粒多、蒙牛纯牛奶、三元铁锌牛奶、三元高钙奶、伊利高钙奶。再送给实验人员用X荧光能谱仪检测，X荧光能谱仪可对样品中的镉、铅、汞、铬总量、溴总量及其他构成元素进行定量分析，快速判定检测结果。实验人员首先用手持式X荧光能谱仪对7袋牛奶的包装逐袋检测，在检测时，还在每袋牛奶包装的多个不同部位检测。接着，实验人员又使用更先进的台式X荧光能谱仪对这7袋牛奶检测。

The experiment process:Reporters from the supermarket to buy 7 different brand and packing of milk,Including Erie pure milk/Three yuan walnut peanut milk/Erie grain more/Hoodwinks the cow pure milk/Three yuan zinc iron milk/Three yuan high calcium milk/Erie high calcium milk.Then send them to experiment personnel with X fluorescence spectrometer detection,X fluorescence spectrometer to sample the cadmium/lead/mercury/Total chromium/Total bromide and other composition elements to quantitative analysis,Rapid determination test results.The first experiment personnel with hand-held X fluorescence spectrometer to 7 bags of milk packaging by bag detection,In the testing,Also in each bag milk packaging different position detection.then,Experimental personnel and use more advanced desktop X fluorescence spectrometer to this 7 bags of milk detection.

　　实验结果：7袋牛奶样品的包装上都不含重金属铅、铬、汞。 (记者刘春瑞）
