Sample
People who lived in Taipei and Tainan finish a dietary questionnaire (N=277) and We determined the concentrations of mercury in 529 aquatic products which were buy from Taipei and Tainan.
Methods
We administered a questionnaire to each one and collected the aquatic products. Mercury concentrations in seafood were measured using mercury analyzer (Hiranuma HG-310, Hitachi). A dietitian calculated the quantity of fish consumed and understand the K.A.P. from the questionnaire.
Results
The average levels of total mercury in fish from Taipei and Tainan are 0.113?b0.145 ug/g（0.0037~0.7732 ug/g） and 0.202?b0.403ug/g（0.018~3.106 ug/g）(wet weight), respectively. Estimated the mercury intake of participants in Taipei and Tainan have 7.1% and 35.2% over the recommend value (0.4ug/kg/day) in U.S.EPA and U.S.FDA. In questionnaire analysis, we can find that most interviewers think aquatic products of Taiwan has possible to polluted (76.0%), and the degree of pollute is serious or very serious (31.3%), consider that aquatic products who ate is safe or very safe only accounting for 28.2%.
