利用电感耦合等离子发射光谱(ICP-AES)方法测定了汕头南澳海水养殖区溶解态的重金属在不同水层中的分布.在龙须菜、鱼类和贝类养殖水域检出Fe、Zn、Mn、Pb等重金属,其中微表层(SML)和底层(BW)是这些重金属的主要存在区域.这些重金属在微表层(SML)中的浓度(Fe 27.5-286.5 μg/L,Zn13.5-89.0μg/L,Mn 3.0-12.0μg/L,Pb 7.0-46.0μg/L)明显高于其在亚表层(SSW)中的浓度(Fe23.0-268.0μg/L,Zn 11.0-82.2μg/L,Mn1.5-11.0 μg/L,Pb 6.0-40.5μg/L),表明微表层发生富集现象,富集系数(EF)在1.07-1.39范围内属于轻微富集,其中Mn的平均富集系数最高(EF=1.30),其他金属相近.平均富集系数以贝类养殖水域最高(1.26),其次为鱼类养殖水域(1.19),龙须菜养殖水域最低(1.11),表明贝类养殖水域表面活性最大.龙须菜养殖水域重金属含量较其他养殖水域低.单因子污染评价显示,南澳养殖海域已经受到Zn低度污染,部分水域在一定时间内Pb的污染严重.
利用電感耦閤等離子髮射光譜(ICP-AES)方法測定瞭汕頭南澳海水養殖區溶解態的重金屬在不同水層中的分佈.在龍鬚菜、魚類和貝類養殖水域檢齣Fe、Zn、Mn、Pb等重金屬,其中微錶層(SML)和底層(BW)是這些重金屬的主要存在區域.這些重金屬在微錶層(SML)中的濃度(Fe 27.5-286.5 μg/L,Zn13.5-89.0μg/L,Mn 3.0-12.0μg/L,Pb 7.0-46.0μg/L)明顯高于其在亞錶層(SSW)中的濃度(Fe23.0-268.0μg/L,Zn 11.0-82.2μg/L,Mn1.5-11.0 μg/L,Pb 6.0-40.5μg/L),錶明微錶層髮生富集現象,富集繫數(EF)在1.07-1.39範圍內屬于輕微富集,其中Mn的平均富集繫數最高(EF=1.30),其他金屬相近.平均富集繫數以貝類養殖水域最高(1.26),其次為魚類養殖水域(1.19),龍鬚菜養殖水域最低(1.11),錶明貝類養殖水域錶麵活性最大.龍鬚菜養殖水域重金屬含量較其他養殖水域低.單因子汙染評價顯示,南澳養殖海域已經受到Zn低度汙染,部分水域在一定時間內Pb的汙染嚴重.

The Fe, Zn, Mn and Pb concentrations in the seawater dissolved phase were investigated in the sea-surface microlayer (SML), subsurface water (SSW) and bottom water (BW) samples collected at of three mariculture areas of the Nanao Island ocean zone. The results showed that the SML and the BW were important compartments for these heavy metals in the madculture areas and the concentrations varied from 23.0 μg/L to 268.0 μg/L(Fe), 11.0 μg/L to 82.2 μg/L(Zn), 1.5 μg/L to 11.0 μg/L(Mn) and 6.0 μg/L to 40.5 μg/L(Pb) in SSW, while a clear enrichment is observed in the SML, where these ranged from 27.5 μg/L to 286.5 μg/L(Fe), 13.5 μg/L to 89.0 μg/L(Zn), 3.0 μg/L to 12.0 μg/L(Mn) and 7.0 μg/L to 46.0 μg/L(Pb). The enrichment factors were in the range of 1.07 - 1.39 which showed a slight enrichment. The average enrichment factors of Fe, Zn, Pb and Mn were 1.18, 1.13, 1.12 and 1.30, respectively. The average enrichment factors in shellfish, fish and gracilada lemaneaformis farming areas were 1.26, 1.19 and 1.11, respectively, which showed that the surface activity was highest in the shellfish farming area. Furthermore, the heavy metals concentrations were lowest in the gracilaria lemaneaformis farming area. The results of single factor contamination index showed that the investigated areas were slightly contaminated with Zn, while the partial farming areas were seriously contaminated with Pd during a certain period of time.
