AB  - OBJECTIVE: To establish a method for the detection of mercury species in aquatic 
      products by liquid chromatography online coupled with cold vapor atomic 
      fluorescence spectrometry(LC-CV-AFS) and to participate in the international 
      proficiency tests to verify the method. METHODS: Mercury species were extracted 
      from aquatic samples by using ultrasonication-assisted acid extraction, separated 
      by reversed phase liquid chromatography, decomposed into inorganic mercury ion 
      with on line UV digestion system, and then determined by cold vapor atomic 
      fluorescence spectrometry. RESULTS: Methylmercury, ethylmercury and inorganic 
      mercury were baseline separated within 20 minutes. The linear range was 1-20 
      microg/L for the three species and the correlation coefficient r > or = 0.999. 
      The detection limits for methylmercury, ethylmercury and inorganic mercury were 1 
      microg/kg, 2 microg/kg and 1 microg/kg respectively. The recovery of samples for 
      three spiked levels (10, 50 and 500 microg/kg) was in the range of 89%-106%. The 
      relative standard deviations (RSDs) were less than 10%. The determined 
      methylmercury contents of certified reference materials (CRMs) were agreed well 
      with the certified values. The results of determined methylmercury values were 
      satisfied (Z <2) in two international proficiency tests, i.e., Food Analysis 
      Performance Assessment Scheme (FAPAS, UK)-07115 test and International Atomic 
      Energy Agency (IAEA)-452 test. CONCLUSION: The LC-CV-AFS method is simple, 
      sensitive and accurate and could meet the demand for mercury speciation in 
      aquatic products.
