摘要
利用ICP/AES和冷原子吸收测汞仪等仪器对海南岛近岸海域表层沉积物中七种重金属元素进行测试,结果表明,样品中重金属元素均有不同程度的检出,该地区重金属元素分布较为分散,体现了不同海域重金属元素的输入输出差距;用Hakanson法评价表明,除受人类活动明显的较大港湾外,海南岛近岸海域表层沉积物中重金属元素富集系数较小,危害程度为轻微污染,总体表明海南岛近岸海域表层沉积物中重金属元素生态风险处于中低水平。
The seven kinds of heavy metals in surface sediments of Hainan Island＇s Inshore are analyzed by ICP/AES and cold atomic absorption mercury meter.The heavy metals have been detected with different extent,the dispersion distribution of heavy metals mean different input and output in different bay of this seas.Hakanson law appraisal shows that the coefficient of heavy metals enrichment is very small and the harm degree is the slight pollution in surface sediments of Hainan Island＇s Inshore except some large bays,where Human activity is frequent.The overall indicates that ecology risk of the heavy metals are in the lower level.
