北极下起“塑料雪”！人间最后一片净土也面临威胁……
<p>遥远的北极，洁白又神秘，一直被视为人类尚未“染指”的人间净土。然而，这片稀罕的美好如今也面临着塑料污染的威胁。</p><p>根据外媒报道，科学家在北极积雪中发现了大量微塑料。</p><p>"<span word="Substantial">Substantial</span>" <span word="amounts">amounts</span> <span word="of">of</span> <span word="plastic">plastic</span> <span word="fragments">fragments</span> <span word="and">and</span> <span word="fibers">fibers</span> <span word="are">are</span> <span word="landing">landing</span> <span word="atop">atop</span> <span word="ice">ice</span> <span word="floes">floes</span> <span word="in">in</span> <span word="the">the</span> <span word="Fram">Fram</span> <span word="Strait">Strait</span>—<span word="an">an</span> <span word="unpopulated">unpopulated</span> <span word="expanse">expanse</span> <span word="of">of</span> <span word="ocean">ocean</span> <span word="between">between</span> <span word="Greenland">Greenland</span> <span word="and">and</span> <span word="the">the</span> <span word="Norwegian">Norwegian</span> <span word="Arctic">Arctic</span> <span word="archipelago">archipelago</span> <span word="of">of</span> <span word="Svalbard">Svalbard</span>—<span word="reports">reports</span> <span word="the">the</span> <span word="study">study</span>, <span word="published">published</span> <span word="in">in</span> <span word="Science">Science</span> <span word="Advances">Advances</span>.</p><p>《科学进展》杂志发布的研究报告称，大量的塑料碎片和纤维落在弗拉姆海峡的浮冰上。弗拉姆海峡是格陵兰岛和挪威北极斯瓦尔巴特群岛之间的一片无人居住的广阔海域。</p><p>由德国和瑞士科研人员组成的研究队伍发现，在靠近弗拉姆海峡中央的某处，大约每964克雪样本中就含有14000个塑料颗粒，所有样本的平均值则为1800个。</p><p>虽然相比德国市区和阿尔卑斯山脉积雪来说，北极地区的微塑料含量相对较低，但仍然构成了污染。</p><p>但研究发现塑料污染不仅在表面，更渗透到了北极冰芯。</p><p>近期，美国研究团队在北极钻取的冰芯中，也发现了大量微塑料。</p><p><span word="Tiny">Tiny</span> <span word="pieces">pieces</span> <span word="of">of</span> <span word="plastic">plastic</span> <span word="have">have</span> <span word="been">been</span> <span word="found">found</span> <span word="in">in</span> <span word="ice">ice</span> <span word="cores">cores</span> <span word="drilled">drilled</span> <span word="in">in</span> <span word="the">the</span> <span word="Arctic">Arctic</span> <span word="by">by</span> <span word="a">a</span> <span word="US">US</span>-<span word="led">led</span> <span word="team">team</span> <span word="of">of</span> <span word="scientists">scientists</span>, <span word="underscoring">underscoring</span> <span word="the">the</span> <span word="threat">threat</span> <span word="the">the</span> <span word="growing">growing</span> <span word="form">form</span> <span word="of">of</span> <span word="pollution">pollution</span> <span word="poses">poses</span> <span word="to">to</span> <span word="marine">marine</span> <span word="life">life</span> <span word="in">in</span> <span word="even">even</span> <span word="the">the</span> <span word="remotest">remotest</span> <span word="waters">waters</span> <span word="on">on</span> <span word="the">the</span> <span word="planet">planet</span>.</p>
