美國一項研究顯示,2024年初收集的人腦解剖樣本中,含有比8年前樣本中更多的塑膠微碎片。
Scientists report that brain samples taken from cadavers were an average of 0.48% microplastic by weight. Tissue from 2024 had significantly more plastic than brain samples from 2016. https://t.co/QUl0P8U4v1

研究:人腦內「呢一異物」比8年前多了50%
CNN新聞網報導,研究首席作者、阿布奎基(Albuquerque)新墨西哥大學(University of New Mexico)藥學系教授坎彭(Matthew Campen)表示,在平均年齡約45或50歲的一般人腦組織樣本中,塑膠濃度為每克4800微克,約佔重量的0.5%。坎彭說:「與2016年的解剖腦樣本相比,這數值高出約50%。這意味著如今我們的大腦99.5%是腦組織,其餘則是塑膠。」
The study describes the brain as one of the most plastic-polluted tissues yet sampled. “It’s pretty alarming, there’s much more #plastic in our brains than I ever would have imagined or been comfortable with.”https://t.co/4APm7fc0MC

藥理學和毒理學副教授:僅顯示腦組織暴露在塑膠微片下的狀況
然而,未參與研究的羅格斯大學皮斯卡特維分校(Rutgers University in Piscataway)藥理學和毒理學副教授絲泰普頓(Phoebe Stapleton)表示,這只顯示了腦組織暴露在塑膠微片下的狀況,並未提供有關腦損傷的資訊。

One study found that plastic made up 0.5% of the brain's weight.

需了解微粒是否會造成中毒
她指出,目前並不清楚,這些微粒實際上是流動的,進出大腦,還是聚集在神經組織中,並引發疾病。絲泰普頓說,需要進一步研究,以了解這些微粒如何與細胞互動,以及是否會造成中毒。
