摘要: The geographical distribution and component characteristics in accumulation of 16 types of polycyclic aromatic hydrocarbons (PAHs) by the oysters from parts of chinese coastal waters was researched in this paper. In the summer and autumn of 2010, 175 sampling sites were set up in liaoning, shandong, zhejiang, fujian and guangdong provinces, and GC-MS was used to analyze the samples. The results indicated the average total content of 16 types of PAHs in the oysters over 175 sampling sites was 3.79 mu g/kg, and the lowest total content of PAHs was in zhejiang province while the highest was in liaoning province. The most component of PAHs in the analyzed samples was phenanthrene, however, two kinds of benzo fluoranthene and dibenzo (a, h) anthrace were not detected. The dominant components of PAHs in samples were Tricyclic structure, and the content of five and six ring PAHs were very low. As a result of our research, overall PAHs residue in oyster samples met the health standards for shellfish of our nation and some developed countries, and can guarantee the safety for consumers.
