In this study, a new method utilizing a sodium compound (either NaCl or Na2CO3) and acetonitrile (MeCN) was developed. The proposed method was validated by comparing the MeHg recoveries (%) of both of the certified reference materials and the market-purchased fish samples to the MeHg concentration obtained using AOAC Official Method 988.11 and the KFSC Method. The experimental results indicate that the newly proposed method in this work is a promising alternative, for its significantly simpler and faster sample pretreatment procedure with a MeHg recovery as high as those of AOAC Official Method 988.11 and the KFSC Method.
