测定了孟加拉湾西北部Rushikulya河口附近海水和浮游动物中铁(Fe)、铜(Cu)、锌(Zn)、钴(Co)、镍(Ni)、锰(Mn)、铅(Pb)、镉(Cd)、铬(Cr)、砷(As)、钒(V)和硒(Se)等痕量金属的含量。在研究期间，海水和浮游动物中痕量金属的浓度呈现出显著的时空变化。海水中的铜和钴水平大多仍未被检测到。其他元素在较高浓度下被发现，并显示出显著的变化。海水中痕量金属平均含量的排序分布为：Fe；Ni；Cd；Cd。铁的生物积累系数最高，其次是锌，镍的生物积累系数最低。相关分析结果表明，海水和浮游动物中的大多数痕量金属之间存在着正的亲和力和良好的相关性，表明它们之间具有很强的亲和力和共存关系。
Concentrations of trace metals such as iron (Fe), copper (Cu), zinc (Zn), cobalt (Co), nickel (Ni), manganese (Mn), lead (Pb), cadmium (Cd), chromium (Cr), arsenic (As), vanadium (V), and selenium (Se) were determined in seawater and zooplankton from the surface waters off Rushikulya estuary, north-western Bay of Bengal. During the study period, the concentration of trace metals in seawater and zooplankton showed significant spatio-temporal variation. Cu and Co levels in seawater mostly remained non-detectable. Other elements were found at higher concentrations and exhibited marked variations. The rank order distribution of trace metals in terms of their average concentration in seawater was observed as Fe > Ni > Mn > Pb > As > Zn > Cr > V > Se > Cd while in zooplankton it was Fe > Mn > Cd > As > Pb > Ni > Cr > Zn > V > Se. The bioaccumulation factor (BAF) of Fe was highest followed by Zn and the lowest value was observed with Ni. Results of correlation analysis discerned positive affinity and good relationship among the majority of the trace metals, both in seawater and zooplankton suggesting their strong affinity and coexistence.
