A study was performed to determine why deep sea fish and shellfish contain a large percentage of mercury. The material selected for study consisted of sediments, corals, seaweeds, and seawater. Total mercury was determined by ultraviolet atomic absorption, and methylmercury was analyzed via gas chromatography. The sediments of the Japan Sea bed contained low (0.001-0.011 ppm) amounts of total mercury. Methylmercury was not detected in the sediments. In corals, total mercury varied according to age; there was a tendency for the accumulation to be larger in the modern living coral than in the old corals. Mercury concentrations in seaweeds varied from none to 0.032 ppm. Methylmercury was not detected in seaweeds. The concentrations detected in this study cannot explain the high levels found in fish and shellfish. The authors speculate that a food chain transfer is operating, its structure being phytoplankton-based. 3 tables.
