우리나라 연안해역 생산 패류 중 다환방향족탄화수소 분석

Polycyclic Aromatic Hydrocarbons (PAHs) were analyzed and safety evaluation was carried out in Korean coastal area. The target congeners were benzo[a]pyrene, benzo[a]anthracene, benzo[b]fluoranthene, and chrysene. The method of analysis was significant. The highest PAHs 4 congener concentrations (12.2 μg/kg) was found in the mussel of Gangwon area. Comparison among the average concentration of PAHs for each congener showed that, benzo[a] anthracene was found in mussel (0.276 μg/kg), oyster (0.463 μg/kg), ark shell clam (1.92 μg/kg), and chrysene was found in mussel (0.848 μg/kg), oyster (1.36 μg/kg), scallop (0.489 μg/kg), sea squirt (3.07 μg/kg), and ark shell clam (0.449 μg/kg). In addition, benzo[b]fluoranthene was found in mussel (0.253 μg/kg), scallop (0.244 μg/kg), and sea squirt (1.64 μg/kg). The most hazardous benzo[a]pyrene was found in mussel (0.147 μg/kg), and scallop (0.244 μg/ kg), it was not detected in the other shellfishes. However, all the PAHs levels recorded in this study did not exceed international MRLs. There was no significant difference among the PAHs concentration in shellfish based on sampling area or species. Body exposure was calculated based on PAHs concentration and intake rate. The results of this study indicated that PAHs in shellfish were within acceptable safe levels.
