Abstract: Microwave digestion technique and cold atomic absorption spectrometl7 was applied to detect the total mercury in shrimp meal samples. The microwave conditions effects recovery rate and the notices were ensured, and the establishment of detection total mercury was made with microw~ive digestion-cold atomic absorption spectrometry. The recovery rate attained 98.3 %-101%, and RSD %was 1.2%-2.1%.
