Scientists have for the first time identified nanoplastics in Antarctic soil, providing compelling evidence that microscopic particles of plastic pollution can traverse the atmosphere and contaminate even the most isolated regions on Earth.
科學家首次在南極土壤中發現了微塑料，這提供了令人信服的證據，證明微小的塑料污染顆粒可以穿越大氣層，甚至污染地球上最孤立的地區。
#2
The groundbreaking study, published in the journal Nanoplastics, revealed that soil samples collected from the McMurdo Dry Valleys contained debris from tire wear alongside five other commonly manufactured polymers.
這項發表於《微塑料》期刊的開創性研究顯示，從麥克默多乾燥谷採集的土壤樣本中，含有輪胎磨損產生的碎屑以及其他五種常見合成聚合物。
#3
Researchers emphasized that this discovery fundamentally challenges the assumption that remote, uninhabited environments remain untouched by industrial contamination.
研究人員強調，這一發現從根本上挑戰了偏遠、無人居住的環境仍未受到工業污染影響的假設。
#4
The McMurdo Dry Valleys, situated among the coldest and driest landscapes on Earth, had long been considered virtually pristine.
麥克默多乾燥谷坐落於地球上最寒冷且最乾燥的地貌之中，長期以來一直被認為幾乎是一塵不染的純淨之地。
#5
Yet the presence of synthetic polymers in this barren terrain suggests that atmospheric transport carries nanoplastics across vast distances, far beyond densely populated or industrialized zones.
然而，在這片荒涼的土地上，合成聚合物的存在表明，大氣傳輸將微塑料帶到了遙遠的地方，遠遠超出了人口稠密或工業化的地區。
#6
The researchers cautioned that both long-range atmospheric currents and localized human activity at nearby research stations may have contributed to the contamination.
研究人員警告，遠距離的大氣環流和附近研究站的局部人類活動，都可能加劇了這次的污染。
#7
Were it not for advanced detection techniques, these infinitesimally small particles might have gone entirely unnoticed.
若非有先進的檢測技術，這些微小至極的粒子可能就完全不被察覺了。
#8
While microplastics have dominated environmental discourse in recent years, experts argue that nanoplastics pose a substantially greater threat.
雖然微塑料在近年來主導了環境議題的討論，但專家指出，微塑料（奈米塑料）所帶來的威脅顯著更大。
#9
Measuring less than one micron in diameter, these microscopic particles can become suspended in the atmosphere with remarkable ease, penetrate biological cell membranes, and serve as carriers for additional toxic contaminants.
這些微小粒子的直徑小於一微米，極易懸浮在太空中，穿透生物細胞膜，並作為其他有毒污染物的載體。
#10
Not only have nanoplastics been detected in remote locations such as Greenland and the Alps, but they have now reached the Antarctic interior, a finding that underscores the truly global scale of plastic pollution.
奈米塑料不僅在格陵蘭和阿爾卑斯山等偏遠地區被檢測到，而且現在已經到達了南極內陸，這一發現強調了塑料污染真正具有全球性的規模。
