Abundance of trace elements including toxic heavy metals in water along the Tobe River system are determined by inductively coupled plasma-mass spectrometry (ICP-MS) to identify the origin of high contents of arsenic and antimony in the water around the area. Based on our new data, the highest contents of arsenic and antimony come locally from any groundwater related to the abandoned Koboshi-mine, in which mines mainly stibnite (antimony). The high abundances of the elements are diluted with increase of water volume. As the results, arsenic content through the river system becomes below the 0.01mg/L considered to be environmental criteria. On the other hand, the antimony content in the water is still too high as compared to item to be monitored. This is consistent with results of the previously reported value. We need further monitoring of the antimony contents through the river system.
