微塑料分析

從包裝、袋子和合成服裝到水瓶、化妝品和牙膏,塑料和微塑料無處不在——其中就包括我們的身體內部。微塑料正日益成為全球范圍內的環境和社會問題,全球河流和海洋中漂浮的塑料材料數量日益驚人。微塑料同時還帶來了另外一個問題,那就是這些聚合物碎片顆粒小得肉眼無法看到,它們正在進入我們的河流和海洋環境中——最終進入食物鏈。

微塑料污染的影響與日俱增。因此,全球范圍內很多組織機構正在表征和量化微塑料及其起源以及微塑料對環境和食物鏈的影響,從而找到針對這一重大問題的解決方案。

幫助推動微塑料研究向前發展

為了更好識別和量化微塑料以及微塑料中的有機污染物和細菌污染物,為了更好衡量微塑料對海洋和淡水生態系統以及食物鏈的生物影響,我們根據七十多年方法開發方面的經驗推出了全套創新解決方案,能夠幫助您獲得準確可靠的結果。

針對您的微塑料研究需求,其中包括對微塑料及相關污染物進行識別,對海洋生物有機體以及基因組和蛋白質組學效應進行生態毒理學研究,您現在可以選擇與一家值得信賴且知識淵博的供應商合作:珀金埃爾默。

僅供科學研究使用。不適用于臨床診斷。

聚合物識別

紅外(IR)光譜技術是聚合物識別所用的主要分析手段之一。我們可以提供一系列先進儀器,從Spotlight? 200i和Spotlight 400紅外成像系統,到便攜、快速和操作方便的Spectrum Two?紅外系統。所有這些系統均配備現成的方法、譜庫和獨有的Spectrum Touch?軟件。研究人員可使用這些儀器對合成聚合物塑膠微粒進行識別和定量,也可用于分析水中的其他化合物-從可見塑料到小于100 μm的微塑料。

微塑料作為棲息地

微塑料表面積聚的生物膜會聚集殺蟲劑等有機污染物。海洋生物攝入此類污染物后會受到傷害,進而將這種傷害通過食物鏈傳遞到我們的餐桌上。色譜法和質譜法有助于識別和測定這些污染物,自動化樣品制備,例如固相萃取則可以讓整個過程更加高效。此外,下一代測序等基因組學技術也可以用于表征附著在生物膜上的細菌。

對生物有機體的影響

人們逐漸開始擔心微塑料對海洋生態系統和淡水生態系統的影響,尤其是食物鏈的影響。除浸出有害添加劑外,微塑料能夠生成一層表面生物膜,而生物膜會聚集殺蟲劑等有機污染物并吸引潛在有害的細菌。這種生物區被海洋生物攝入之后會對生物體本身、食物鏈和人體健康造成潛在影響。微塑料如何影響生物有機體的生殖、生長和繁殖,以及免疫應答的變化,以及如何導致感染性提高等問題都是至關重要的,因為這些問題都會影響食物鏈。針對身體的傷害,有證據表明滲透到組織或大腦的微小顆粒會導致行為變化。該研究需要細胞成像和分析技術、基因測序和蛋白質組學工具。
