“…Inhabitants of Minamata city and its surrounding areas have suffered from exposure to mercury by consuming contaminated seafood from the Minamata bay; 2,265 residents were certified as Minamata disease patients by 2003 (http://www7.ocn.ne.jp/*mimuseum/). A great number of pathological, clinical and epidemiological studies have been conducted so far to understand the etiology and the extent of damage (Harada 1995;Ninomiya et al 1995). In the late of 1950s, elevated concentrations of mercury were reported in fish, crustaceans, and shellfish from Minamata bay region (Kitamura et al 1960).…”

The concentrations and distribution of heavy metals, such as mercury, zinc, copper, lead, and iron in surface sediments from 234 stations of the Yatsushiro Sea including Minamata bay were investigated. High concentrations of mercury were found in sediments from Minamata bay and its vicinity, but the levels decreased gradually with distance from the bay. The concentrations of mercury in sediments decreased gradually from south to north of the Yatsushiro Sea. These imply the lack of movement of mercury from Minamata bay to the northern Yatsushiro Sea. The geographical profiles of zinc and copper were contrary to that found for mercury, indicating the presence of natural and anthropogenic sources of copper and zinc in the northern Yatsushiro Sea.

“…Such a type of case was liable to become chronic. For instance, neurological disorders such as a hypoesthesia at the distal parts of the extremities and around the lips, which were considered to be caused by a long-term dietary exposure to methylmercury compounds, were still detected among residents in a fishing village in Goshoura-jima island 10 years after the cessation of methylmercury dispersion from Minamata (Ninomiya et al 1995). On the other hand, delayed MPM is defined as the latent development of methylmercury poisoning after multiple years of cessation from a long exposure through contaminated food (Miura 2014).…”

This chapter outlines the methylmercury poisoning in Minamata (MPM): about the history, symptom pathogenesis, research on the causal agent, and responses of the national and local governments and the responsible company, i.e., Chisso, to the outbreak of MPM. A book written by Nishimura and Okamoto (2001) played an important role to clarify the mechanism of the MPM outbreak. Based on this book and the published data on mercury concentrations of aquatic organisms and newborns' umbilical cords, how methylmercury generated in the plant, flew into the sea, transferred to aquatic organisms, and was consumed by residents are explained. Victims of MPM, compensation and environmental restructure, and court ruling against this incident are described. Based on lecture notes from a university course, students' suggestions for avoiding a repeat of the tragedy are also introduced.
