      Scientists Find High Levels of Plastics in Arctic Snow

      科學家在北極雪中發現高含量的塑料

      Scientists say they have found high levels of small plastic particles in Arctic snow. Their findings provide more evidence that plastic is entering Earth's atmosphere and traveling great distances around the planet.

      科學家表示他們在北極雪中發現了高含量的小型塑料顆粒。他們的發現提供了更多的證據證明塑料正在進入地球大氣并且圍繞這地球行程了很遠的距離。

      A new report describing the discovery was published in Science Advances.

      描述這次發現的一個新報告被發表在了Science Advances上。

      A German-Swiss research team collected snow samples from the Arctic and other areas. They included northern Germany, the Bavarian and Swiss Alps, and the North Sea island of Heligoland.

      一個德國和瑞士的研究團隊從北極和其他地區搜集了雪樣。這些地區包括德國北部、巴伐利亞、瑞士阿爾卑斯山和黑爾戈蘭島的北海島。

      When the researchers examined the samples in a laboratory, they were surprised to find very high levels of microplastics.

      當研究人員在實驗室檢驗樣品時,他們驚奇地發現高含量的微型塑料。

      Microplastics are very small pieces of plastic. These plastic particles are generally smaller than 5 millimeters in length. Other studies have found microplastics in the environment. They come from the disposal and breakdown of man-made plastic products and industrial waste.

      微型塑料是小型塑料。這些塑料顆粒的長度通常小于5毫米。其他的研究發現了環境中的微型塑料。他們來自于人造塑料產品和工業廢物的處理和降解。

      Melanie Bergmann co-wrote the report on the new study. She told The Associated Press that while her team did expect to find some microplastics in the samples, they were surprised by the very large amounts.

      梅勒妮·伯格漫也參與寫作這項新研究的報告。她告訴美聯社當她的團隊確實期望在這些樣品中找到一些微型塑料,他們被非常高含量驚訝到了。

      Bergmann is a researcher at the Alfred-Wegener-Institute in the German city of Bremerhaven.

      伯格漫在德國城市不來海港的阿爾弗雷德-韋格納-研究所擔任研究員。

      The study found the highest levels of microplastics came from the Bavarian Alps. One snow sample from the area had 154,000 microplastic particles per liter. Samples collected from the Arctic had much lower levels. However, even samples from the Arctic contained up to 14,000 particles per liter, the study found.

      這項研究發現最高含量的微型塑料來自布伐利亞的阿爾卑斯山。來自該地區的雪樣每公升含15萬4000個微型塑料顆粒。從北極搜集來的樣品的含量要低很多。然而,研究發現來自北極的雪樣甚至每公升包涵1萬4000個顆粒。

      Earlier studies found signs of plastic in Arctic areas. Those microplastics were found in coastal areas, sea ice, the seafloor and the seawater's surface.

      更早的研究在北極地區發現了塑料存在的跡象。那些微型塑料在海洋地區、海冰里、海底和海水表面被發現。

      The new study attempted to explore how some of the material could have been carried in the atmosphere. A limited number of earlier studies did find microplastics in the air of some cities, including Paris, Tehran and Dongguan, China.

      這項新研究試圖探索一些這樣的材料是如何在大氣中被運輸的。有限數量的更早的研究確實在這些城市的空氣中發現了微型塑料。這些城市包括巴黎、德黑蘭和中國的廣東。

      Bergmann said in a statement she believes the new study clearly shows that "the majority of the microplastic in the snow comes from the air." She said this idea is supported by research that studied the atmospheric movement of pollen from plants. In those studies, scientists confirmed pollen had traveled great distances to reach the Arctic.

      伯格漫在一次聲明中表示她相信這項新研究清楚地顯示出雪中的微型塑料的大多數來自空氣。她表示這個看法由發現植物花粉在大氣中移動的研究作為支撐。在那些研究中,科學家們確定花粉行程了更遠的距離到達了北極。

      Other studies found that dust particles – which are similar to microplastics - traveled more than 3,500 kilometers from the Sahara Desert to the northeast Atlantic.

      其他的研究發現與微型塑料相似的微塵顆粒從撒哈拉沙漠行程3千500千米的距離到達大西洋的東北部。

      Bergmann said the new study suggests that much of the microplastic found in Europe and the Arctic comes from the atmosphere and snow. "This additional transport route could also explain the high amounts of microplastic that we've found in the Arctic sea ice and the deep sea in previous studies," she said.

      伯格漫表示這項新研究表明在歐洲和北極被發現微型塑料中很多都來自大氣和雪。她表示”“這種額外的運輸路徑也解釋了在先前的研究中在北極海洋冰和深海中發現的高含量的微型塑料”。

      The research team discovered many kinds of microplastics. Some were from paints commonly used to coat the surface of automobiles and ships. A rubber-like substance was also found that could have come from vehicle or boat parts or packaging materials, the report said.

      這個研究團隊發現了很多種類的微型塑料。一些來自通常用于覆蓋汽車和輪船表面的漆。報告稱研究發現的一種很像橡膠的物質可能來自車輛或者輪船的零件或者包裝材料。

      While there is growing concern about the effect of microplastics on the environment, scientists are still studying their possible harmful effects on humans and animals.

      當對環境中存在的微型塑料產生的影響擔憂越來越大時,科學家仍然在研究他們對人類和動物可能產生的有害影響。

      Bergmann said she hopes the new study will lead to more research on this issue. She also said she believes that microscopic plastic particles should be included in worldwide observations of air pollution levels.

      伯格漫表示她希望這項新研究將引導在這個問題上的更多的研究。她也表示她相信微型塑料顆粒應該被包含全球在空氣污染指數觀測中。

      "We really need to know what effects microplastics have on humans, especially if inhaled with the air that we breathe," Bergmann said.

      “我們真的需要了解微型塑料對人類有什么樣的影響,尤其是我們將其與空氣一起吸入時。”
