摘要
利用原子吸收光谱仪和原子荧光分光光度计测定钦州茅尾海表层沉积物中7种重金属元素(Cu、Pb、Zn、Cd、Cr、Hg、As),并采用瑞典学者Hakanson沉积物重金属潜在生态危害指数评价该海域重金属污染程度和潜在生态危害。结果,7种重金属元素含量均小于一类国家标准值,7种重金属潜在生态危害系数和指数均远低于轻微污染上限值。该海域属于较清洁海域。
The contents of 7 heavy metal elements(Cu、Pb、Zn、Cd、Cr、Hg、As) in surface sediments in Maowei Sea were analyzed by atomic absortion spectrometry and atomic fluorescence spectrometry.The Hakanson's potential ecological risk factors and risk indices of heavy metals were used to assess the potential ecological risk of heavy metals marine ecosystem in water areas of Maowei Sea.The result showed that the potential ecological risk of heavy metals was low and Maowei Sea is clean water areas.
