Metals such as Cd, Pb, Cu and Zn were analysed in five seagrass species from five locations of the Palk Bay coast of south-eastern India. The maximum Cd concentration (2.83 ± 0.08 μg g) was recorded in Syringodium isoetifolium on the Mallipattinam coast in the post-monsoon season, and the Cu (29.54 ± 1.03 μg g) in Enhalus acoroides of the Thondi coast during monsoon season. The maximum concentrations of Pb (3.12 ± 0.14 μg g) and Zn (52.66 ± 0.88 μg g) were observed in S. isoetifolium and Cymodoceae rotundata on the Devipattinam and Karangadu coasts, respectively, during the monsoon season. The metal concentrations obtained in different seagrass species varied significantly among species, and no clear monsoon season had a clear effect on the accumulation of heavy metals in the investigated seagrass species. S. isoetifolium has higher capacity for Cd and Pb accumulation than other tested seagrass species.
在印度东南部帕尔克湾海岸的五个地点的五种海草中分析了 Cd、Pb、Cu 和 Zn 等金属。在季风后季节的马利帕坦姆海岸，在 Syringodium isoetifolium 中记录到 Cd 的最大浓度（2.83±0.08μg g），在季风季节的 Thondi 海岸的 Enhalus acoroides 中 Cu 的浓度最高（29.54±1.03μg g）。在季风季节，在 Devipattinam 和 Karangadu 海岸的 S. isoetifolium 和 Cymodoceae rotundata 中，Pb（3.12±0.14μg g）和 Zn（52.66±0.88μg g）的最大浓度最高。不同海草物种中的金属浓度在物种间差异显著，季风季节对所研究的海草物种中重金属的积累没有明显影响。S. isoetifolium 比其他测试的海草物种具有更高的 Cd 和 Pb 积累能力。
