The Red Sea is exposed to metals from a large variety of natural and anthropogenic sources. In this study, we analyzed 19 common element concentrations in 14 Red Sea zooplankton samples using inductively coupled plasma-optical emission spectrometry (ICP-OES). The average metal or metalloid concentrations of the Red Sea zooplankton were: Ca > Sr > Fe > Al > Zn > As > Cu > Mn > Cr > Mo > Ni > Pb > Cd. The As, Ca, and Cu concentrations significantly increased with increasing latitude, while Cd concentrations decreased (p < 0.01). Our study indicated that anthropogenic activities (i.e., cement factories and oil refining industries) might be the predominant sources of significantly high Cr (1718 mg/kg), Fe (11,274 mg/kg), Mn (57.3 mg/kg), Mo (286 mg/kg), Ni (226 mg/kg), Pb (332 mg/kg), and Zn (17,046 mg/kg) concentrations that recorded in the Central to North Red Sea zooplankton.
红海受到来自多种自然和人为来源的金属影响。在本研究中，我们使用电感耦合等离子体发射光谱法（ICP - OES）分析了14个红海浮游动物样本中的19种常见元素浓度。红海浮游动物中金属或类金属的平均浓度为：钙>锶>铁>铝>锌>砷>铜>锰>铬>钼>镍>铅>镉。砷、钙和铜的浓度随纬度增加而显著增加，而镉的浓度则下降（p < 0.01）。我们的研究表明，人为活动（即水泥厂和炼油厂）可能是红海中部至北部浮游动物中铬（1718毫克/千克）、铁（11274毫克/千克）、锰（57.3毫克/千克）、钼（286毫克/千克）、镍（226毫克/千克）、铅（332毫克/千克）和锌（17046毫克/千克）显著高浓度的主要来源。
