摘要
采用金属潜在生态危害系数和危害指数的评估方法，评价了大亚湾海域重金属对海洋生态系统的潜在危害。结果表明，大亚湾海域重金属潜在生态危害轻微，而养殖海区和近岸海区的重金属潜在生态危害则相对较重，大亚湾海域重金属的潜在生态危害较珠江口外浅海轻。
Potential ecological risk (PER) factors (Eri=Tri Cfi) and risk indicesof heavy metals were used for assessing the PER of metals to marineecosystem in the water area of the Daya Bay. The results showed that the PER ofheavy metals was low in the water area of the twa Bay but relahvely high in thecultural and coastal water areas. The PER of heavy metals in the water area of theDeya Bay was lower than in the shallow sea out of Zhujiang fuver estuary.
