[392-2] Dead Zones / 死區, 2016
Dead Zones, or hypoxic areas, are aquatic regions with low oxygen content, primarily due to nutrient pollution by humans. The oxygen zapping pollutants render the areas unlivable for much marine life. Hypoxia can be coastal, or it can occur in major lakes and rivers due to agricultural pollution, such as fertilizer run-off, and make its way outwards towards coastal ocean waters.
「死區」是指低氧水域，通常是因為人類所造成的優養化所引起的污染現象。造成水體溶解氧含量下降的汙染物使得這些區域變成不適宜許多水中生物所居住。這樣的缺氧現象可能會發生在海域，或是大型湖泊與河川中，汙染源來自農業生產，例如造成沿海水域的汙染的肥料徑流。
