双酚A是被获许添加使用的 Bisphenol A is obtained permission to add use

　　新华网记者：从医学专业角度看，网上流传的消息属实吗？为什么？

Xinhuanet reporter：From the point of medical professional perspective，The news spread online is true？why？

　　王志鹏：网上流传的并不属实，双酚A致癌性至今尚无明确定论，且通过皮肤接触是否致癌也无任何研究报道证实。

WangZhiPeng：Online spread is not true，Bisphenol A carcinogenicity so far there is no definite conclusion，And through the skin contact is carcinogenic nor any research reports confirm。

双酚A对生殖系统并致癌的实验性研究尚无定论 Bisphenol A on reproductive system and carcinogenic experimental research remains to be seen

　　新华网记者：“双酚A”具体是一种怎样的物质？

Xinhuanet reporter：“Bisphenol A”Concrete is a kind of what kind of material？

　　李鹏鸽：双酚A，也称BPA，下图是其结构简式。双酚A主要用于塑胶生产，使用史已达50多年，对塑料主要是增加透明度、起防碎防冲击性功能。因此广泛用于食品和饮料的包装、奶瓶、水瓶、牙齿填充物所用的密封胶、眼镜片以及其他数百种日用品的制造过程中。双酚A在生活中已广泛应用，成为人们经常能接触到的物质。因此，其安全性问题也成为了公众的关注的焦点，但其应用存在一定争议。

Li pigeon：Bisphenol A，Also called BPA，Below is the structure Jane type。Bisphenol A is mainly used for plastic production，Use history has amounted to more than 50 years，Plastic is mainly to increase transparency、The shatter-proof strike sexual function。It is widely used in food and beverage packaging、bottle、Aquarius、Teeth filler used sealant、Spectacle lens and other hundreds of daily necessities manufacturing process。Bisphenol A in the life has already been applied extensively，Become people can often come into contact with the material。therefore，The safety problems have become the focus of public attention，But its application has some disputes。

　　王志鹏：双酚A是一种弱内分泌干扰物，可以模仿雌激素，从理论角度上说其确实可能会导致对健康的负面影响。但其主要影响的人群确是胎儿及婴幼儿的早期发育阶段(目前仍对此存在争议)。美国食品和药物管理局(FDA)已确定了双酚A对人类的安全水平，但目前，这些安全水平受到质疑或正在审查。总体而言，根据目前的实验证据，不支持双酚A对健康的负面影响(包括致癌性)。目前欧盟的欧洲化学品管理局，欧洲食品安全局和美国食品和药物管理局(FDA)的科学委员会得出的结论是目前水平的双酚A，没有向一般人群传播癌症的风险。之前说到双酚A的真正可能的致病性是在胎儿及婴幼儿人群中，对此，在2012年4月，FDA已禁止使用含有双酚A的婴儿奶瓶。

WangZhiPeng：Bisphenol A is A kind of weak endocrine disruptors，Can imitate estrogen，From a theoretical perspective says it may lead to the negative influence of the health。But the main effect of the crowd was indeed the fetus and infant early developmental stage(This is still controversial)。The United States food and drug administration(FDA)Has identified A bisphenol A to the human safety level，But at present，These safety level questioned or under review。In general，According to the present experimental evidence，Does not support bisphenol A negative impact on health(Including carcinogenicity)。The European Union of the European chemicals administration，The European food safety agency and the United States food and drug administration(FDA)Scientific committee came to the conclusion that the current level of bisphenol A，The general population not to spread the risk of cancer。Said before to bisphenol A real likely pathogenicity is in the fetus and infants in the crowd，this，In April 2012，FDA has banned the use of contains bisphenol A baby bottles。

　　新华网记者：购物小票、打车票是否真的含有双酚A？双酚A平时主要应用在哪里？

Xinhuanet reporter：Shopping small、Play ticket is not really contains bisphenol A？Bisphenol A mainly applied in where？

　　王志鹏：作为热敏纸的首选介质，双酚A是被获许添加使用的。双酚A在19世纪末被发现 ， 在20世纪30年代开始应用，双酚A最初的两个用途： 第一是为刺激牛和家禽的增长速度；第二个用途是作为一些妇科疾病的雌激素替代疗法。 自20世纪50年代以来，双酚A被广泛商用化，婴儿奶瓶、瓶装水，运动器材、医疗设备， 牙科填充物和密封剂、CD和DVD光盘，家用电子产品、眼镜镜片、 几乎所有的包装食品和饮料罐的内衬，当然还有我们日常使用的热敏纸介质(购物小票)。

WangZhiPeng：As a thermal paper preferred medium，Bisphenol A is obtained permission to add use。Bisphenol A in the 19th century was found ， In the 1930 s application，Bisphenol A first two purposes： The first is to boost the rate of growth of beef and poultry；The second purpose is as a disease of a few department of gynaecology estrogen replacement therapy。 Since the 1950 s，Bisphenol A is widely commercial applications，Baby bottles、Bottled water，Sports equipment、Medical equipment， Dental filling material and sealants、CD and DVD，Household electronic products、Glasses lens、 Almost all of the packing food and drink cans of lining，And of course our daily use of thermal paper medium(Shopping small)。

　　可见我们目前的日常生活中根本离不开双酚A，双酚A的雌激素样作用的第一个证据来自对老鼠的实验在20世纪30年代进行的，但直到1997年的不良影响低剂量暴露对实验动物首次被提出( 毒物兴奋效应 )。至于通过皮肤接触双酚A而致癌的“谣言”则是被完全夸大了。从严谨角度来说，目前双酚A是否致癌的研究还在动物实验当中，结果还属于未知数，而通过皮肤传播癌症则更没有任何可信数据可言，也没有任何研究证实接触热媒纸介质(含双酚A)会直接导致癌症的报道。

Visible our present in daily life can't live without bisphenol A，Bisphenol A estrogen-like effects of the first evidence from the experiment in the mice in the 1930 s，But until 1997 the harmful effects of low dose exposure to experimental animals were put forward for the first time( hormesis )。As for through the skin contact bisphenol A and carcinogenic“rumors”Is be completely exaggerated。From the rigorous point of view，At present bisphenol A is carcinogenic research also in animal experiments，The results also belongs to the unknown，And through the skin cancer is spread more no credible data whatsoever，No any research confirmed contact heat medium paper medium(Including bisphenol A)Will directly cause cancer reports。

有关部门应制定相关使用标准 The relevant departments shall enact relevant use standard

　　新华网记者：如何避免双酚A的危害？

Xinhuanet reporter：How to avoid the dangers of bisphenol A？

　　李鹏鸽：目前国内外双酚A的毒性研究资料主要为动物调查和实验研究结果，关于双酚A毒性作用的人群流行病学调查和人体试验研究的报道相对较少。资料表明，双酚A属低毒性化学物。初步的实验表明它能导致内分泌失调，影响人的生殖系统，威胁着胎儿和儿童的健康。癌症和新陈代谢紊乱导致的肥胖也被认为与此有关，但“剂量大小决定危害”。因此，相关政府部门应该制订相关标准，来规范“双酚A”的使用。(记者 陶叶 姜春媛)

Li pigeon：At home and abroad and bisphenol A toxicity research material mainly for animal research and experimental results，About bisphenol A toxic effect crowd epidemiological survey and human test research reports relatively less。Data show that，Bisphenol A is low toxic chemicals。Preliminary experiments show that it can bring about endocrine disorders，Affect the person's reproductive system，Threatening fetuses and children's health。Cancer and metabolism disorder lead to obesity was also think about this，but“Dose size decided to harm”。therefore，The related government department should formulate relevant standards，To regulate“Bisphenol A”use。(Reporter ceramic blade JiangChunYuan)
