インド南東部のパルク湾沿岸の5か所に生息する5種の海草について、Cd, Pb, Cu, Znなどの金属を分析した。カドミウムの最大濃度(2.83±0.08μgg)はMallipattinam海岸のSyringodium isoetifoliumで、銅の最大濃度(29.54±1.03μgg)はThondi海岸のEnhalus acoroidesで記録された。また、モンスーン期には、デヴィパッティナム海岸ではPb(3.12±0.14μgg)、カランガドゥ海岸ではZn(52.66±0.88μgg)の最大濃度が観測された。また、モンスーン期が重金属の蓄積に明確な影響を与えることはなかった。S. isoetifoliumは他の試験対象種に比べてCdとPbの蓄積能力が高いことが明らかになった。
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.
