Delphinus delphis, which living in the southern East Sea of Korea was investigated for the study of methylmercury distribution in the big aquatic mammals. Methylmercury(MeHg) in 4 kinds of common dolphins(male, female, young and old) was determined with GC/ECD. Methylmercury was extracted with hydrochloric acid and toluene, and cleaned up with L-cystein solution. Limit of detection(LOD) and Limit of quantitation(LOQ) were 5.8μg/kg, and 17.7μg/kg, respectively. Calibration linearity was estimated by R² which was 0.99 and Relative Standard Deviation(RSD%) was 1.5%. These results could show us the understanding of bioaccumulation of methylmercury in the aquatic mammals from the food cycle of fish and the toxicological knowledge from this methylmercury concentration distribution. Keywords: common dolphin, methylmercury, concentration distribution
