The concentrations of five metals (Zn, Cd, Cu, Ni, and Pb) in Tokyo Bay water were determined using inductively coupled plasma atomic emission spectrometry (ICP-AES). Eighteen stations were selected for the survey from the environmental standard points, and water samples in the surface, middle and bottom layers were collected from each station for metal concentration determination. The metal concentrations (μg · <I>l</I><sup>-1</sup>) ranged from <2 to 73 for Zn, <0.1 to 1.8 for Cd, <2 to 20 for Cu, <20 to 44 for Ni, and <2 to 3.9 for Pb. Similarly to the PRTR data, Zn concentration was higher along the Tokyo and Kanagawa areas than along the Chiba area. Two water samples had a Zn concentration exceeding the water quality standard concentration for "aquatic life class A". Thirteen water samples had a Zn concentration exceeding the water quality standard concentration for "aquatic life class special A".
