micro plastics positive in 进入你 体 inner
plastics tube/pipe =隐形杀手?
今 year, 包括星巴克 in inner less enterprise positive in 尝试停 use plastics tube/pipe, use 直饮杯 cover/cap and 纸质吸 tube/pipe. tube/pipe new cover/cap and 纸质吸 tube/pipe use 不便遭 to 一 网友 吐槽, as is front research field/area 科学仪 device company editor, also is non 常肯定 this enterprise method, 也号召 more more enterprise and add decrease/reduce plastics use action in.
因 is, positive is this 一看似不起眼 small small plastics tube/pipe, positive in bad 球生态 system, formed is 威胁人 type 健康 “隐形杀手”.
据《福布斯》杂志 statistics, 2017 year, full separation 钟卖出约100万 plastics water bottle, however, has 9% by recycling utilizing. its in plastics tube/pipe this category of products, 因体积 very small, usually can 躲 自动化 recycling by 填埋, has versus 当一部 separation by 冲入河流湖泊 and 海洋, by material especially is 海洋生 material 摄入, *终进入人 type inner. world forum 警告说, to 2050 year,海洋 in plastics will ratio also need more.
this small small plastics tube/pipe how to can 够威胁我们 生命呢?
事实 upper, this by recycling utilizing large small plastics in cationic light, gas and 海洋 共同 function lower, *终都会碎裂 or degradation is relatively small sheet/slice, its dimensions small 于5 mm 时, is “ micro plastics ”. and “ white 污染” can plastics versus ratio, this micro plastics difficult separation 辨, more add is, it can through 层层食 material 链进入人体.
无处不 in “ micro plastics ”
very more 人会问: “ if 我不吃鱼, 不吃任何海鲜, is is micro plastics effect/influence to 我?”答案依然 is 否定. upper, currently research 发现, micro plastics already 经渗透 to type ring 境 各 食 material strip/profile in.
according to 《国家 理》2018 year report, research for full world more Brand salt 进行 抽样 testing, its in 90%都发现 micro plastics, 亚洲食 salt in micro plastics density is high, therefore by 该杂志列 is plastics focus/key point 区.
not only is salt and other material, in 人们看不见甚至 difficult 以想象 方, micro plastics in. 据《时代》杂志报道, has research for 9 国家购买 11 Brand 259例 bottle water testing, its in 90% above water in has micro plastics. is micro plastics very small, scope/range in micron to mm, has can in micro lower can to, therefore can light through use water 杂质 滤 device.
“ micro plastics ”危害 has how much
事实 upper very more plastics 本身都 tool has property, environmental protection material in high temperature high pressure and other conditions lower also 会释放出 has material 质, to type belt/tape 二次伤害. in addition, plastics as is types polymer/macromolecule polymer, in different degree upper poly 集污染 material, fine 菌, 病毒, chemical material and has type and other, formed is has material 质 “载体”.
阿肖克•德什潘德博士 is USA 东北渔业科学 in chemical 家, for micro plastics in and other field/area effect/influence has in-depth research, for micro plastics effect/influence table/sheet 示忧虑, “ plastics is type and fine 菌殖民 运输 pipeline, 我们每 人都无 method micro plastics effect/influence “.
显然, in 健康隐患令人胆战心惊, already very difficult overlook micro plastics belt/tape effect/influence, it positive in through various 看 见看不见 methods 进入人体 inner.
拉曼 light force, anti already formed 效
无处不 in micro plastics already to 我们 生存敲响警钟, anti as in 眉睫. is, currently micro plastics already formed is day 益受关注 话题, research already in full large and research machine 构开启.
need for this 看不见 micro plastics, is its type type, 进而确定 ring 境污染 material 源, in 此基础 upper, can has for property for 污染源进行监测 and control.
currently already has multiple technology by used for 帮助科学家 table/sheet micro plastics 进而确认 its 污染源. 德什潘德博士 through research 发现, inner micro plastics can use gas versus color 谱(GC) hot understanding, 质谱, outer light or light and other multiple technology table/sheet 征. its in, micro light due to formed light and optical micro 镜,既 can obtain sample micro 形貌, also can to sample specific 位置 拉曼 light 谱, therefore formed is polymer high 效, has technology 手段之一.
utilizing micro light can 够进行 micro analysis, table/sheet micron grade material this advantages, 德什潘德博士团队 will to micro plastics light and already polymer light 谱库进行 ratio for, from light 松识别出 micro plastics types type, is its provide can based on.
made good micro plastics sample and other 待进行 analysis
而 add large more more large 学生态 and 进化生 material 学系切尔西•罗奇曼博士 and its in 团队, will research focus/key point in utilizing light 谱仪获取 micro plastics type type, dimensions and amount and other upper. utilizing XploRA™PLUS拉曼 light 谱仪进行 research, development sleeve/set fast speed 简便且准确 micro plastics sample table/sheet methods, from improve/increase table/sheet efficiency.
她指出“因 is has more different type type plastics, is table/sheet this material, 进而衡 amount it for material effect/influence, 像拉曼显 micro this analysis tool is can less. ”
milli 无疑问, this 科学家 research is ring 境污染 material 源, 进而监测 control 污染源找 to high methods.
HORIBAXploRA™PLUS智 can type full 自动拉曼 light 谱仪
注: understanding research in HORIBA拉曼 light detailed introduction and use issues, 欢迎点击 left lower 角“ reading 原文”留言, technology expert fast 联系您进行答疑 understanding 惑.
micro plastics “循 ring ” in research
currently, is 科学家 already can table/sheet separation micro plastics. 德什潘德博士 table/sheet 示, lower is 识别出贝 type and other small material in small fiber, from understanding micro plastics is how to through material 链层层富集进入人体. is material is 层层递进, type micro plastics, again lower type and other 浮游生 material, type relatively large 海洋生 material also 会吃掉 relatively small 鱼, this process in micro plastics in 一层层富集. can 想象, has how much strip/profile 鱼摄入 micro plastics, 处于食 material 链顶端 我们遭受 micro plastics 污染就 has more heavy.
decrease/reduce plastics, from 我做起
for micro plastics 追本溯源 is 科学家们 in 做 事, as is 普通人 我们 can what 呢?*近进行 如火如荼 waste classification is important methods, through recycling utilizing dispersion in large small plastics, its 流入湖泊海洋进入人体;抑 or is more use environmental protection bag plastics bag; less outer is methods, outer box/case use more for 健康无益. its 实我们 can 做 事情 also more.
