| 内容記述 | The relationship between dissolved Cd and phosphate in the euphotic zone in the East China Sea from March (winter) to May (spring) in 1993 was investigated. The concentrations of phosphate decreased during winter-spring due to the uptake by phytoplankton. Cd also decreased at inner shelf station (50 m depth), whereas little change in the concentration was observed at the station on the central shelf (90 m depth). Plotting [Cd] vs. [phosphate] results in a convex curve about a straight line through the origin. By assuming that the uptake rates are first-order, the following relationship were obtained: [Cd]=exp (0.190 In [phosphate]-1.28) and [Cd] =exp (0.0324 In [phosphate]-2.03) for the inner shelf and central shelf stations, respectively, where 0.190 and 0.0324 in those equations represent the ratios of the rate constants for the uptake of Cd and phosphate by phytoplankton. The obtained ratio at the station in the central part of the continental shelf was smaller than that of inner shelf station, which suggested higher growth rare of the phytoplankton in the central part, consequently higher productivity in that area. | |||||
