GC-EI-MS was used to analyze several phthalates in aquatic products. The samples were extracted in ultrasonic bath and cleaned by column chromatography. The linear range of the method was extensive （20.0 - 800 μg/kg, and the correlation coefficients were lager than 0.9995）. The precision was better （RSD≤ 14% ）. The limit of detection was lower （LODDMP= 0.711μg/kg; LODDEHP = 5.67μg/kg）. The recoveries ranged from 74.8% to 119%. It was applied to analysis of hard clam, kelp and octopus, which contains DBP and DEHP. Still,...
