Mercury contents of samples of sea water and shellfish from Kagoshima Bay, volcanic ashes, rain water, sediments in rivers, and the surface soil from the area surrounding a waste incinerator in the city of Kagoshima were measured to search for the source of mercury in Magoshima Bay. The results obtained were as follows :I Mercury contents of sea water samples at 26 stations in Kagoshima Bay ranged from 6.3 to 19.7 ng/l. When the 26 stations were classified into four areas, the entrance, the middle and the interior of the Bay, and the water around the Sakurajima area, mercury contents of the samples from the last area were significantly higher than either at the entrance or in the interior of the Bay. Methylmercury contents of sea water samples at the coast around Sakurajima were lower than those at the Minamata-Hyakken port, but higher than those at the coast of Minamata-Yunoko.2 Mercury contents of fish from the shine coast station, the innermost part of the Bay, were significantly hi … More gher than those from the other collecting stations. Moreover, significant interactions between the species of fish and the sampling stations were detected.3 River sediments obtained 1 km from the mouth of each river contained from 4 to 96mug/kg of mercury. Mercury contents of the river sediments from the Wide river were higher than those from the other five rivers examined. Mercury contents obtained from the surface soils every 0.5 km in eight directions, with the waste incinerator as the central point, ranged from 6 to 128 mug/kg ; however, neither distance nor direction showed significant differences.Possible sources of mercury in Kagoshima Bay were mainly eruptive products of Mt. Sakurajima and partly man-made products such as mercury-containing pesticides. Mercury levels in the bay remain unchanged with a state of mercury balance between the eruptive products from the increasing activity of Mt. Sakurajima and the reduction of man-made ones by administrative control. Mercury in the environment of Kagoshima Bay should be monitored for the prevention of human disease caused by consuming mercury contaminated fish. Less

为了探索马儿岛湾汞的来源，测定了鹿儿岛湾海水、贝类、火山灰、雨水、河流沉积物、鹿儿岛市垃圾焚烧炉周围表层土壤中的汞含量。结果表明：鹿儿岛湾26个测站海水中汞含量为6.3 ~ 19.7ng/l。当26个站点被分为四个区域，入口，中间和内部的海湾，和周围的樱岛地区的水，从最后一个区域的样品的汞含量显着高于在入口或在海湾内部。樱岛沿岸海水样品中甲基汞含量低于水俣百剑港，但高于水俣汤子港。2樱岛沿岸鱼类样品中甲基汞含量显著高于水俣百剑港和汤子港，而樱岛沿岸鱼类样品中甲基汞含量显著高于水俣百剑港和汤子港。 ...更多信息 比其他收集站的要多。此外，还检测到鱼类种类与采样站之间存在显著的相互作用。3从每条河流河口1公里处采集的河流沉积物中含有4至96微克/千克的汞。从宽河的河流沉积物中的汞含量高于其他五条河流检查。以垃圾焚烧炉为中心点，沿8个方向每隔0.5km测得的表层土壤汞含量为6 ~ 128 μ g/kg，但距离和方向差异均不显著。樱岛和部分人造产品，如含汞农药。海湾中的汞水平保持不变，汞平衡状态之间的喷发产品从越来越多的活动山。樱岛和减少人为的行政控制。应监测鹿儿岛湾环境中的汞，以预防人类因食用受汞污染的鱼类而患病。少
