Organic mercury in organic tissue (squid) was analyzed by cold vapor atomic absorption spectrometry. For a reducing procedure, a newly designed simple reducing cell was used instead of conventional reaction vessel apparatus. To assess the simple reducing cell apparatus, recovery experiment was carried out. Certain amounts of organic mercury (such as CH_3HgCl) were added to squid tissue. Then it was analyzed. The recovery was 96-98% average, and coefficient of variation 2.1-3.3%. When organic mercury in squid was analyzed, by use of both present method and gas chromatography (ECD-GC) method, it was found that in the liver organic mercury concentration was the highest (0.0292 and 0.0289 ppm wet weight) among several tissue samples of squid. No variance in result was recognized between these two methods.
