[Annual daily intakes of Hg, PCB and arsenic from fish and shellfish and comparative survey of their residue levels in fish by body weight].
We have been surveying toxic substances in food and foodstuffs and carrying out a total diet study on the intakes of various substances since 1979 in cooperation with local public institutes in Japan. In this paper, we report the daily intakes of mercury, PCB and arsenic from foods, and the relation between the concentrations of these substance in fish and the fish body weight. The intakes of mercury and arsenic were 6.9-11.0 micrograms/ man/day and 120-230 micrograms/man/day, respectively. The intakes of these substances remained on a stable level from 1979 to 1994. On the other hand, the intake of PCB decreased from 3.1 micrograms/man/day in 1979 to 0.9 microgram/man/day in 1994. Most of the intakes of mercury, PCB and arsenic were derived from the diet group "fish and shellfish". The level of mercury in fish increased with increasing fish body weight. For PCB and arsenic, there was no correlation between these concentrations in fish and the fish body weight, except that mackerel and croaker show a higher concentration of PCB when they are small. Arsenic shows almost a constant level in each fish regardless of their body weight.
