Trace metals in zooplankton from the northern Persian Gulf

2018

This work is the first study on the spatial and temporal distribution of metals in zooplankton collected along the Persian Gulf. The rank order distribution of metals in terms of their overall average concentration in the zooplankton was observed to be Fe > Zn > Cu > Cd > Ni > Cr > Pb > Co > V. No clear pattern and no statistical differences were detected among the areas and the sampling stations. The highest concentrations of Cu, Zn, and Pb were observed in summer while the highest concentration levels of Fe and Ni were observed in winter. The highest mean zooplankton metal concentration level was found to be Fe with 10.42 μg/g (in winter) and the lowest levels were for V (in spring and summer) and Co (in winter), both of which had a level of 0.01 μg/g. The results can be used to establish base-line data for the trace metal content of zooplankton in the northern region of the Persian Gulf.
