Abstract

Toxicity of mercury has been known since ancient times, and it became clear that organic mercury (methyl mercury) is especially toxic to the central nervous system of human beings etc. through bioaccumulation due to Minamata disease in Japan during the 1950s - 1960s. As a result, the amount of mercury used in Japan have reduced, but the amount in the world have increased due to the economic growth in Asian countries and similar disease to Minamata disease has occurred. Then, in 2017 Mercury Convention on Mercury came into force from the perspective of environmental protection on a global scale and it is a trend to comprehensively regulate the use of mercury and the emissions of mercury into air,water and soil. Initiatives at universities to contribute to reducing environmental impact. Proper management and use of mercury-containing reagents and mercury-containing products are required, and proper disposal of unwanted mercurycontaining products and mercury wastes are required. Therefore, proper knowledge of characteristics, toxicity and handling for mercury, accurate mercury analysis, proper treatment of mercury wastes, and removal of mercury pollution are important. Here, changes of analytical techniques of mercury, two methods for the determination of trace mercury without the interference of iodide, and removal method in the case of mercury contamination has occurred at the University laboratory were explained.
