南京猪肉铅含量超38%，吃了会变傻？ Nanjing pork lead over 38%,Ate a dull boy?

　　昨天上午7点半，新浪微博上一位名为“环保董良杰”的网友发布一则微博称：“南京农大动物学院研究员随机检测南京市场上猪肉，发现南京猪肉铅超标率达38%”，之后还加了一段短评：“铅超标可致暴力、降低智商。铅在食物链上传递，猪变更蠢无所谓，人吃多了会变得凶狠又愚蠢”。这位网友的实名认证为：“原美国夏威夷大学环境专家”，再加上微博内容关乎食品安全，短时间内这条微博就被疯狂转发。

Yesterday morning at half past seven,Sina blog a micro called"Environmental protection DongLiangJie"The net friend published a micro bo said:"Nanjing nongda animal college researcher random testing on nanjing pork,Find nanjing pork which lead up to 38%",Then he added a paragraph:"Lead paint can cause violence/Lower IQ.Lead in the food chain transfer,Pig change stupid doesn't matter,People eat much can become vicious and stupid".The net friend of authentication for rule:"The original American university of Hawaii environmental experts",Plus micro bo content for food safety,A short time this article micro bo was crazy forward.

　　该微博发布后，立即引起“南京发布”微博管理人员的注意，并迅速上报，引起市政府高度重视，多个部门立即介入调查。

The micro bo after release,Immediately set"Nanjing release"Micro bo management personnel's attention,And rapidly report,Cause the municipal government attaches great importance to,Many departments immediately intervention survey.

调查发现，这是一篇不规范且引用标准错误的论文 Survey found,This is a non-standard and reference standard error of the thesis

　　经与南农大动物科技学院领导和原论文指导老师及作者交流，这篇“论文”有诸多问题。

With the south nongda college of animal science and technology leadership and the original thesis guidance teachers and the author communication,This article"The paper"There are many problems.

　　论文是由南京农业大学动物科技学院某教授的研究生于2011年7月25日，在南京部分超市及农贸市场购买了13份鲜猪肉，每份约100克，经其实验室购买的微波消解炉消解后，用该学院的电感耦合等离子体质谱仪(ICP-MS)进行测定。分析数据表明铅含量最大值为每千克0.131毫克，参照农业部2009年3月9日颁布的“铅限量标准每千克0.1毫克”，得出了 “南京部分猪肉中存在一定的铅超标现象，超标率达38.46%” 的结论。

Thesis is from nanjing agricultural university college of animal science and technology MouJiaoShou research was born in July 25, 2011,Part of the supermarket in nanjing and farmer's market bought 13 a fresh pork,Each about 100 grams,With the laboratory purchase microwave digestion furnace after digestion,The college of inductively coupled plasma mass spectrometer(icp-ms)Were determined.Analyzed data show that the maximum levels for each kilogram 0.131 mg,With reference to the ministry of agriculture on March 9, 2009 promulgated"Lead the limited standards of 0.1 milligram per kg",obtained "Nanjing part in pork there are some lead paint phenomenon,Which reaches 38.46%" conclusion.

　　但是，该论文存在三大问题。

but,The paper there are three big problem.

　　一是研究论文的猪肉铅检测实验室不具权威性。该实验室是南京农业大学动物科技学院畜产品质量检测实验室，未通过国家质量机构认证，同时，本次采样时，也没有按照国家采样规范实施采样。

One is the research papers of pork lead detection laboratory not authoritative.The laboratory is nanjing agricultural university college of animal science and technology of animal product quality testing laboratory,Not through the national quality authentication institutions,At the same time,When the sampling,No according to the national sampling to standardize the implementation sampling.

　　二是研究论文结果判定依据引用不当。该研究采样13份，铅含量最高值每千克0.13毫克，作者判定结果是错误地引用了 绿色食品“肉及肉制品”标准，即猪肉铅含量低于每千克0.1毫克。而按照GB 2707-2005国家鲜畜肉卫生标准，猪肉铅含量不得超过每千克0.2毫克，应为合格。

The second is the decision basis for the research papers quote inappropriate.The study of sampling 13,High levels of 0.13 milligram per kg,The author decision results was wrong to reference the green food"Meat and meat products"standard,Namely pork with less than 0.1 milligrams per kilogram.And according to GB 2707-2005 national fresh livestock meat hygiene standards,Pork lead must not exceed 0.2 mg per kilogram,Should be qualified.

　　三是该文作者在采样方面存在不规范性，样本量过少，不足以代表南京市场猪肉质量状况。学校方面、作者和指导老师均承认，采样缺乏规范，引用标准错误，文字叙述不严谨。“即使抛开检测设备、采样等方面的问题，单单是引用标准，就产生谬以千里的错误。因为这名学生采集的猪肉是市场上的普通猪肉，标准完全符合国家无公害猪肉的标准，但作者却用‘绿色猪肉’的标准去判定，结论肯定是错误的。”专业人士解释道。

The third is the authors in sampling are not normative,Sample size too little,Not by the representative nanjing market pork quality status.schools/The author and the teacher are admitted,Sampling lack of standard,Reference standard error,Text narrative not rigorous."Even ignoring the testing equipment/Sampling, etc,Just the reference standard,Produce a mile mistakes.Because the student acquisition of pork is the market of ordinary pork,Standard completely accords with the standard of national pollution-free pork,But the author but with the‘Green pork’Standard to judge,Conclusion must be wrong."Professional personage explains.

论文作者承认标准引用不当，并表示检讨 The authors admit standard reference undeserved,And said review

　　对于南京市有关部门的调查，该论文作者及所在学院均承认论文结论错误。在南京农业大学动物科技学院就此事件的说明中，该论文作者承认，“由于本人对猪肉质量标准缺乏全面了解，从而得出这一错误结论。正确结论应为‘南京市此次抽检猪肉全部符合无公害猪肉的标准，61.54%符合绿色猪肉的标准’。”同时，当事人承认标准引用不当，并对科研中出现的不严谨表示检讨。

The relevant departments of the investigation for nanjing,The paper authors and the college all admit that the paper conclusion error.In nanjing agricultural university college of animal science and technology in this event descriptions,This paper the authors acknowledge that,"Because I am lack of a thorough knowledge of the pork quality standard,Thus draw the wrong conclusions.Correct conclusion should be‘Nanjing the check pork all accord with the standard of non-pollution pork,61.54% conform to the standard of green pork’."At the same time,The parties admitted improper reference,And the research appeared in not rigorous review said.

南京将立即再次组织专项监督检测 Nanjing will immediately once again organization special supervision and detection

　　这一未经证实的微博引起了市民对南京市猪肉安全的关心。昨天，市农委就此澄清，南京市场猪肉符合国家无公害猪肉标准。本着对市民食品安全高度负责的精神，南京市近期立即组织相关部门对市场销售猪肉开展专项监督检测。

The unproved micro bo caused the citizens in nanjing pork safety concern.yesterday,City agriculture commission on the clarification,Nanjing market pork accord with national pollution-free pork standard.In line with the citizens to food safety highly responsible spirit,Nanjing recently immediately organize the relevant departments to carry out marketing pork special supervision and detection.

少数“名微”未经求证转发，理性网民质疑 minority"Name micro"Forward without verification,Rational netizens question

　　南京市委宣传部相关人士表示，尽管这是一篇存在很多错误的论文，但下午4点，微博转发量已超过2000次，评论也超过500条，拥有近450万粉丝的网络名人薛蛮子也对此进行转发。但是，这一微博也引起不少理性网民特别是具备专业知识网民的质疑。国内著名科学论坛“科学松鼠会”成员“松树云无心”就在第一时间指出这篇文章中所使用的安全标准存在问题，并认为该论文引用标准错误，表述不当：“这篇论文中的含铅最大值是每公斤0.13毫克，按照国家规定的‘无公害猪肉’标准并不超标。文中认为超标是因为引用的标准是每公斤0.1毫克，我不清楚引用的是哪个标准。”

Nanjing municipal party committee propaganda department relevant personage says,Although this is an existence many wrong paper,But at four in the afternoon,Micro bo forward volume has more than 2000 times,Review article also more than 500,With nearly 4.5 million fans network celebrity xue barbarian also carries on the forward.but,The micro bo also causes many rational netizens especially possess professional knowledge of Internet users questioned.Domestic famous science BBS"Scientific squirrel will"members"Pine cloud centerless"In the first time pointed out that this article use safety standards existing problems,And that the paper quoted standard error,misrepresentation:"This paper lead the maximum is 0.13 mg per kilogram,According to the provisions of the state‘Pollution-free pork’Standards are not overweight.This paper think that overweight because reference standard is 0.1 mg per kilogram,I don't know what is the reference standard."
