加拿大地质学家最近发现,一些海底热液泉会向海洋中释放出汞元素。这一新发现显示,海底热液泉有可能是鱼类等生物体内汞污染的来源。 加拿大地质勘探局专家对取自新西兰普伦蒂湾一带海底热液泉的样本进行分析后发现,海底热液泉会将海底沉积物中所含的纯汞和硫化汞释放到海水中,每个海底热液泉每年释放 Canadian geologists have recently discovered that some seafloor hydrothermal springs release mercury into the oceans. This new finding shows that hydrothermal springs on the seabed may be sources of mercury contamination in organisms such as fish. An analysis by Canadian Geological Survey experts of samples taken from the seabed hydrothermal springs in the Bay of Plenty area in New Zealand found that the hydrothermal seabed releases pure mercury and mercury sulphide contained in seabed sediments into seawater, each of which Seabed hydrothermal springs are released each year
