Assessment of mercury contents of tuna in East Indonesian seas

Abstract

Samples of meat were taken from tuna landed at Ambon, Biak, Bitung and Denpasar between August 1989 and February 1990 at two month intervals. They were flown to Jakarta for assessment of their mercury content. It was found that the mercury content did not increase with size of tuna. The mercury content of tuna was generally well below 0.5 ppm, although samples from Ambon were higher than those from other three landing places.
