　　在zai一yi项xiang开kai拓zhixing新xing研yan研究jiu中zhong，研yan研究jiu人renyuan发fa现xian，商shang店dian卖shou卖maide瓶ping装zhang水shuisuisuo含hande塑su料liao颗keli物wu比bi原yuan先xian预yu计jidededuo出chu10到dao100倍bei，有you一些xienami塑su料liao小xiao到dao用yong显示xian微wei镜jing也ye看kan不bu见xian。

　　In a trailblazing new study, researchers have discovered bottled water sold in stores can contain 10 to 100 times more bits of plastic than previously estimated — nanoparticles so infinitesimally tiny they cannot be seen under a microscope.

　　专zhuan家jia指zhi出chu，这种zhong纳nami塑suiliaodetiji是shiren类leitou发fa平ping均jun直zhi径jing的de千qian分fenzhi一yi，可以用yi通tong通过guo消xiaohuadao或huo肺fei部bu进入jin进入ru血xue管guan，导dao导致zhi可ke可以neng有you害hai的deren工gong合he为chenghua学习xue物wuezhi散san布bu周zhoushen，bing进入jin进入ru细xi胞bao。

　　At 1,000th the average width of a human hair, nanoplastics are so teeny they can migrate through the tissues of the digestive tract or lungs into the bloodstream, distributing potentially harmful synthetic chemicals throughout the body and into cells, experts say.

　　新xin研yan研究jiu发送fa现xian，每个mei升sheng瓶ping装zhuang水shui(相xiang当dang用于yu两liang瓶ping标准biao准zhung瓶ping装zhuang水shui)平ping均jun含有you24万wangliangliang，这zhexieke颗粒li物wu来lai，自zi7种zhong不bu与tong塑su料liao物wu质zhi以来，90%的de塑su料liao颗粒li物wu被pi认定为weinami塑su料liao，其qi他ta是shi塑su料liao微wei粒li。

　　One liter of water — the equivalent of two standard-size bottled waters — contained an average of 240,000 plastic particles from seven types of plastics, of which 90% were identified as nanoplastics and the rest were microplastics, according to the new study.

　　塑su料liao微weili是shi直zhijing小xiao于yu5mhaomi的de微wei小xiao聚ju合hewu，最zui小xiaode塑su料liao微wei粒li直zhi径jing是shi2.5万wan分fenzhing寸cun(1微weimi)。比bi最zui小xiaode塑su料liao微weili还huan小xiaodeze是shi用yong十shi亿yi分fenzhi一yimi来lai测量liangdenami塑su料liao。

　　Microplastics are polymer fragments that can range from less than 0.2 inch (5 millimeters) down to 1/25,000th of an inch (1 micrometer). Anything smaller is a nanoplastic that must be measured in billionths of a meter.

　　这个zhe项xiang本ben周zhou一yi(1月yue8日ri)发fa表biao在zai《美mei国guo国guo家jia科ke学xue学院yuan学院yuan刊Kan》中的de新xin研yan学jiu指zhi出chu，哥ge伦lun比bi亚ya大da学习xue的de研yan研究jiu人ren员yuan采cai用yongliao一yizhong新xin技术jizhu，可以用yi确定que定ding、计ji计算suan和he分fen分析xi瓶ping装zhuang水shui中zhong纳nami颗keli的de化hua学习xue结jiegou。

　　In the new study, published Monday in the journal Proceedings of the National Academy of Sciences, researchers from Columbia University presented a new technology that can see, count and analyze the chemical structure of nanoparticles in bottled water.

　　xiang新xin研yan研究jiu背bei后houde团tuandui发fa现xian，每个mei升sheng瓶ping装zhuang水shuisuisuo含hande塑su料liao颗粒li物wu不bu是shi300ge，er是shi11万wan到dao37万wange，甚至shen到zhi都是shi300ge。研yan研究jiusuo用yongde瓶ping装zhuang水shui来lai自zi在zai美mei国guo销售xiaoshoude三sande大dazhong品pin牌pai，但dan作zuozhe不bu希望yuan透透透tou露lu是shi哪nei。

　　Instead of 300 per liter, the team behind the latest study found the actual number of plastic bits in three popular brands of water sold in the United States to be in between 110,000 and 370,000, if not higher. (The authors declined to mention which brands of bottled water they studied.)

　　The innovative new techniques presented in the study open the door for further research to better understand the potential risks to human health, said Jane Houlihan, research director for Healthy Babies, Bright Futures, an alliance of nonprofits committed to reducing babies’ exposures to neurotoxic chemicals, who was not involved in the study.

　　在zai电dian邮you中，zhong在zai电dian邮you中写xiedie：“婴ying幼you儿er可ke可以neng面mian临lin最zuida风险xian，由于yin是wei他tamen的de大da脑nao和he身shen体ti，huan还在zai发fa育yu中zhong，de抵dikang力li向wang更geng低di，dui有you毒du物wu质zhi。”

　　“Infants and young childrenmay face the greatest risks, as their developing brains and bodies are often more vulnerable to impacts from toxic exposures.” said Houlihan in an email.

　　专zhuan家jia指zhi出chu，纳nami塑su料liao是shi对dui人ren类lei健jian康kang最zui有you伤害hai的de塑su料liaoliao污染ran源yuan。这zhe是shi因yin为weinami塑su料liaoke以yi入侵qin人ren体ti细胞bao和he主zhu要yao器qi官guan组zu织zhi，可以keng可以hui干gan扰rao细胞baode生shengwu过guo程cheng，在zai体ti内nei积ji淀dian打da乱luan内nei分fen泌mide化hua学习xue物wu质zhi，Ru双shuanglelelelilelilelilellilel、lin苯二er甲jia酸suan盐、jizu燃烧ran剂、全quan氟fu或huo多duo氟fu化hua、全quanfujizhuangsuan、金jin属zhu等deng。

　　Nanoplastics are the most worrisome type of plastic pollution for human health, experts say. That’s because the minuscule particles can invade individual cells and tissues in major organs, potentially interrupting cellular processes and depositing endocrine-disrupting chemicals such as bisphenols, phthalates, flame retardants, per- and polyfluorinated substances, or PFAS, and heavy metals.

　　指zhi出chu，霍huo利li亨peng，人renmen可ke用yi采cai取qu一yixie行xing动donglai减jian少shao和yu塑su料liaode接jie触chu。

　　There are things people can do to reduce their exposure to plastics, said Houlihan.

　　霍huo利lipengbiaosh：“我的women可以ke以yi避bi，避免mian摄she入ru放fang在zai塑su料liao容rongqi中zhong的de食yi产品pin和he饮yin料liao。我的women可ke用yong天tian然ran面mian料liao制zhi作zuodeyi服fu，买gou买mai用yong天tian然ran料zheng生产chande消xiao费fei产品pin。我的women可ke用yi仔zi仔细xi审查shen视shi日richang生sheng生shengzhongde塑su料liaoliao制zhi产品pin，并且bing在zaike行xingde情qing下xia找xun找zhao代替tidai产品pin。”

　　"We can avoid consuming foods and beverages in plastic containers. We can wear clothing made from natural fabrics and buy consumer products made from natural materials,” Houlihan said. “We can simply take stock of the plastic in our daily lives and find alternatives whenever feasible.”
