並非一無是處 霧霾或許可以延緩全球變暖

Chinese experts claimed that smog can delay global warming because the particles help oceans absorb carbon dioxide.

近日有中國專家表示，霧霾可以減緩全球變暖，因爲霧霾中的微小顆粒有助於海洋吸收二氧化碳。

The smog does nothing aside from damaging people's health and the terrestrial ecosystem, Li Weijun, a professor at Shandong University, and Shi Zongbo, a researcher at the University of Birmingham, told the Science and Technology Daily last Monday.

上週一，山東大學教授李衛軍、英國伯明翰大學研究員時宗波向《科技日報》透露，霧霾除了損害人類健康和破壞陸地生態系統外，沒有任何壞處。

Li said that scientists have believed for a long time that the acid produced by human activity and emissions can allow the insoluble iron oxide to convert into soluble iron, and if the particle settles on the surface of the ocean, it can allow the organisms on the surface of the ocean to effectively use iron and encourage the growth of marine microorganism.

據李衛軍表示，科學家們在很長一段時間裏一直認爲，由人類活動和自然排放形成的酸性物質，能夠促進不可溶解鐵氧化物向可溶解鐵轉變，如果這些顆粒物沉降於海洋表面，就能夠增加海洋表面生物可有效利用的鐵。

The process can store more carbon dioxide in the ocean and delay the global warming process, said Li, adding that previously there was no evidence to prove that the acid substance helps insoluble iron content convert into soluble.

李衛軍表示，這一過程會導致更多的二氧化碳儲存在海洋中，起到減緩全球變暖的作用，並指出之前沒有證據證明酸性物質有助於不溶性鐵轉化爲可溶性鐵。

However, scientists found particles produced by steel factories and coal factories in the Yellow Sea region contain iron substances and are surrounded by sulfate.

但是科學家們卻發現，黃海海域附近的鋼廠和煤廠產生的廢氣顆粒中含有鐵物質，並被硫酸鹽包裹。

The sulfate surface contains soluble iron, which provides "solid evidence" for the theory.

這些硫酸鹽表面含有可溶性鐵，從而爲上文的理論提供了“鐵證”。
