Trường hợp Tiểu Sử: Ngộ độc thủy ngân ở Nhật Bản và các địa điểm khác Chương này rộng rãi ý kiến tập tài liệu ngộ độc thủy ngân ở Minamata, Nhật Bản, và một thời gian ngắn đánh giá các sự cố nhiễm độc thủy ngân khác trong Niigita Prefecture (Nhật Bản), Tokuyama Bay (Nhật Bản), Quý Châu (Trung Quốc), quần đảo Faroe, Cộng hòa Seychelles, Ontario (Canada), và New Zealand. | Part 4 Case Histories 2006 by Taylor Francis Group LLC Chapter 10 Case Histories Mercury Poisoning in Japan and Other Locations This chapter extensively reviews the well-documented mercury poisoning episode at Minamata Japan and briefly reviews other mercury intoxication incidents in Niigita Prefecture Japan Tokuyama Bay Japan Guizhou China the Faroe Islands the Republic of Seychelles Ontario Canada and New Zealand. MINAMATA JAPAN One of the earliest and most extensively documented cases of mercury poisoning occurred in the 1950s at Minamata Bay in southwestern Kyushu Japan especially among fishermen and their families Irukayama et al. 1961 1962a 1962b Fujiki 1963 1980 Irukayama 1967 Tsubaki et al. 1967 Kitamura 1968 Matida and Kumada 1969 Matida et al. 1972 Takeuchi 1972 Kojima and Fujita 1973 D Itri and D Itri 1977 Smith and Smith 1975 USNAS 1978 Takizawa 1979a 1979b 1993 1994 Tamashiro et al. 1984 1985 Elhassani 1983 Nishimura and Kumagai 1983 Doi et al. 1984 Futatsuka and Eto 1989 Takeuchi et al. 1989 Davies 1991 Sakamoto et al. 1991 Eto etal. 1992 Matsumura etal. 1993 Silver etal. 1994 Eisler 2000 . Deaths and congenital birth defects in humans were attributed to long-term ingestion of marine fish and shellfish highly contaminated with methylmercury compounds. An abnormal mercury content of greater than mg kg FW was measured in fish and shellfish from the Bay Table . The source of the mercury was in waste discharged from an acetaldehyde plant that used inorganic mercury as a catalyst between 1932 and 1968 Minamata Bay received at least 260 tons of mercury and perhaps as much as 600 tons. A severe neurological disorder was recognized in late 1953 and had reached epidemic proportions by 1956. At that time the mercury level in sediments near the plant outfall was about mg kg FW this decreased sharply with increasing distance from the plant and sediments in the Bay contained between and mg Hg kg FW. Concentrations of mercury in fish .
