近期网上“修正液3分钟毒死小白鼠”的实验视频引发热议。修正液里究竟有哪些危害？近日，记者随机购买四种修正液、两种修正带，跟随专业人员检测显示，4种修正液均检出三氯乙烷，且苯含量都超标严重，连“无苯配方”的修正液也超标近4倍。而修正带中也检出甲醛，具有潜在放射性的锆和铌物质也让6种样品更添些许隐患。

Recent online"Correction fluid 3 minutes poisoned mice"Experimental video trigger hot debate.Correction fluid exactly what harm?recently,Reporter random buy four kind of correction fluid/Two kinds of tape,With professional testing shows,Four kinds of correction fluid are detected trichloroethane,And benzene content are overweight serious,even"No benzene formula"The correction fluid also overweight nearly four times.And correction tape in the detection of formaldehyde,Potential radioactive zirconium and niobium material also let 6 kinds of sample more add some hidden trouble.

修正液多有刺鼻气味 There are many correction fluid pungent smell

　　12月13日、15日，在丰台的路通市场、六里桥亿客隆两家小商品市场的多家文具摊位，记者注意到很多摊主销售的修正液以“晨光”牌为主，每瓶售价3元左右。打开这些修正液，均有少许刺鼻味。

On December 13/15,In the fengtai leads the market/LiuLiQiao hundred million guest long two small commodity market several stationery booth,Reporter noticed that many vendors selling correction fluid to"The morning"Brand is given priority to,The price is 3 yuan.Open the correction fluid,All have a little pungent taste.

　　路通市场一位女摊主称，她更推荐孩子们用修正带，因为修正液涂到纸上效果不如修正带，又有味儿，容易沾到手上。

Leads the market a female stand the Lord says,Her children more recommended with tape,Because the correction fluid coating to paper not as effective as correction tape,And the smell of,Easy to stick to a hand.

　　记者购买了常见的4种品牌修正液，以及2种品牌的修正带，送到北京服装学院材料科学与工程学院的实验室，由专业检测人员对重金属、有机溶剂、甲醛进行测试。

Reporter bought 4 kinds of common brand correction fluid,And 2 kinds of brand of tape,To Beijing institute of clothing technology materials science and engineering college laboratory,By professional testing personnel to heavy metal/Organic solvent/Formaldehyde testing.

　　其中，4种修正液的外包装上，除了1种没有标出成分组成外，其余3种标示的主要成分都包含有甲基环乙烷、钛白粉，并提醒在使用中不可吞食，不可近火，一款修正液还醒目地写明“安全无毒”、“无苯配方”等字样。而2种修正带外包装上标明的主要成分完全一样，写着：钛白粉、耐热性树脂、聚苯乙烯、自粘胶、光滑脱离纸。

the,Four kinds of correction fluid on the outer packing,Except for one kind of not mark the composition,The rest of the three main components of the labeled contains methyl cyclohexane/Titanium pigment,And remind in use do not swallow,Not near fire,One correction fluid was seen clearly"non-toxic"/"No benzene formula"Words such as.And two kinds of tape on the outer package marked the main component of exactly the same,written:Titanium pigment/Heat resistant resin/polystyrene/Since the viscose/Smooth from paper.

“无苯配方”仍超标数倍 "No benzene formula"Still overweight several times

　　记者查询国家标准《学生用品的安全通用要求》规定，修正液等涂改制品中的有机溶剂苯含量应不超过10mg/kg，不应含有氯代烃。但实验显示，4种修正液都含有超标的苯，而且有2种品牌的苯含量最高超标6.7倍。标称“无苯配方”的修正液，苯含量也达到49mg/kg，超标3.9倍。同时还含甲苯、对二甲苯物质。

Reporter inquires the national standard[Student supplies general requirements for safety]provisions,Correction fluid and alter products of organic solvent benzene content should be not more than 10 mg/kg,Should not contain chlorinated hydrocarbon.But experiments show that,Four kinds of correction fluid containing exceeds the benzene,And there are two kinds of brand of benzene content exceed the highest 6.7 times.nominal"No benzene formula"Of correction fluid,Benzene content also reached 49 mg/kg,Overweight 3.9 times.At the same time also contain toluene/Paraxylene material.

　　最值得注意的是，4种修正液都检出了属于氯代烃类化合物中的三氯乙烷，最高含量为69mg/kg。

The most notable is,Four kinds of correction fluid are detected a belongs to the chlorinated hydrocarbon compounds of trichloroethane,The highest content is 69 mg/kg.

　　事实上，中消协多年前就对修正液进行过比较试验，当时19种样品全含有毒物质。市工商局此前在对市场上文具的质量监督监测中，也发现修正液苯超标和氯代烃的问题。

In fact,Many years ago annual to correction fluid a comparison test,When all the samples of 19 species contain toxic substances.City industrial and commercial bureau in the market after the quality supervision and monitoring of stationery,Also found that correction fluid benzene exceed bid and chlorinated hydrocarbon problem.

实验1 Experiment 1

　　样品均检出潜在放射性物质 Samples are detection potential radioactive substances

　　实验目的：检测修正样品中是否含有害重金属。

The purpose:Test whether correction sample containing harmful heavy metals.

　　实验过程：检测人员将B、C、J、L四种修正液各取2ml挤到样品池，放到X射线荧光能谱仪的样品固定台里。启动仪器检测，约10分钟后可观测到结果。

Experimental process:Testing personnel will B/C/J/L four correction fluid from each 2 ml crowded to sample pool,In X-ray fluorescence spectrometer samples in fixed bed.Start instrument detection,About ten minutes can be observed results.

　　随后，把修正带涂到一张白纸样本上，将纸样放进X射线荧光能谱仪的探测口约50秒，即可显示结果。

then,The tape with a white paper on the sample,The pattern in the X-ray fluorescence spectrometric detection mouth about fifty seconds,Can show the results.

　　实验结果：4种修正液中都没有检出铅、镉、铬、汞、砷、钡、锑等有害重金属。但发现了重金属锆和铌。实验人员分析，锆和铌都是一些放射性元素的终产物，具有潜在放射性，可能在生产中没有分离干净而带入。

The experimental results:Four kinds of correction fluid is no detection lead/cadmium/chrome/mercury/arsenic/barium/Antimony and other harmful heavy metals.But found heavy metal zirconium and niobium.The researchers analyzed,Zirconium and niobium are radioactive elements of the end product,Potential radioactive,May in the production of clean and no separate into.

　　另外，C、Y两品牌修正带同样也未检出铅、镉等有害重金属。但Y修正带检出锆和铌，C修正带含有少量锆。

In addition,C/Y two brand tape also was not detected lead/Cadmium and other harmful heavy metals.But Y correction tape detection zirconium and niobium,C correction tape contains a small amount of zirconium.

　　【提示】锆、铌均具有潜在放射性，在一些特定环境下可能引发基因突变、癌变，不过修正液、修正带的锆和铌含量极其微小，一般情况下不用刻意回避。

[tip]zirconium/Niobium are potentially radioactive,In some specific environment could cause gene mutation/canceration,But correction fluid/Correction tape zirconium and niobium content is very small,Usually don't deliberately avoided.
