  • Bisphenol A is widely used in plastic and other industrial consumer products. Release of bisphenol A and its analogues into the aquatic environment during manufacture, use and disposal has been a great scientific and public concern due to their toxicity and endocrine disrupting effects on aquatic wildlife and even human beings. More recent studies have shown that these alkylphenols may affect the molting processes and survival of crustacean species such as American lobster, crab and shrimp. In this study, we have developed gas chromatography with flame ionization detection (GC-FID) and gas chromatography-mass spectrometric (GC-MS) methods for the determination of bisphenol A and its analogues in shrimp Macrobrachium rosenbergii, blue crab Callinectes sapidus and American lobster Homarus americanus samples. Bisphenol A, 2,4-bis-(dimethylbenzyl)phenol and 4-cumylphenol were found in shrimp in the concentration ranges of 0.67-5.51, 0.36-1.61, and < LOD (the limit of detection)-1.96 ng/g (wet weight), and in crab of 0.10-0.44, 0.13-0.62, and 0.26-0.58 ng/g (wet weight), respectively. In lobster tissue samples, bisphenol A, 2-t-butyl-4-(dimethylbenzyl)phenol, 2,6-bis-(t-butyl)-4-(dimethylbenzyl)phenol, 2,4-bis-(dimethybenzyl)phenol, 2,4-bis-(dimethylbenzyl)-6-t-butylphenol and 4-cumylphenol were determined at the concentration ranges of 4.48-7.01, 1.23-2.63, 2.71-9.10, 0.35-0.91, 0.64-3.25, and 0.44-1.00 ng/g (wet weight), respectively. At these concentration levels, BPA and its analogs may interfere the reproduction and development of crustaceans, such as larval survival, molting, metamorphosis and shell hardening.

  • The use of uncertain names for imported crustaceans causes considerable confusion for the establishment of government policies and the public market. Therefore, there have been demands for reestablishment of the domestic names of imported fish to correct the market order and to prevent damage caused by confusion among consumers. A total of 118 species of imported fisheries crustaceans were reviewed (47 crab spp., 36 shrimp spp., 27 lobster and crayfish spp., five mantis shrimp spp., and three horseshoe crab spp.). Although not belonging to the Subphylum Crustacea, three species of the Subphylum Chelicerata and five species of the Order Stomatopoda were included for review. Of these, 49 species that require Korean name assignment and reexamination of domestic names were selected and Korean names were assigned.

  • 기존에 생선 검출을 위한 ELISA 개발은 여러 편 보고된 바 있으나, 고등어만을 특이적으로 검출하는 방법에 관한 보고는 거의 없었다. 본 연구에서는 고등어 parvalbumin에 대한 토끼 항체를 이용하여 가공식품 중 고등어의 검출을 위한 ELISA를 개발 하였다. 암모늄침전법과 Sephadex G-50 column chromatography를 이용하여 열에 안정한 12 kDa의 고등어 parvalbumin을 분리, 정제하였다. 여기에서 얻어진 parvalbumin을 토끼에게 면역하여 생산한 항 parvalbumin 항체 및 특이항체-HRP 복합물을 이용하여 샌드위치 ELISA(sELISA)의 조건을 확립하였다. 이때 parvalbumin 의 검출한계는 3 ng/mL이고, 고등어(생살)의 검출범위는 5-5,000 ${mu}g/mL$이었다. 이어서. 광어, 우럭, 오징어, 꽃게, 꽁치, 대구, 새우, 연어, 바다가재, 고등어에 대한 교차반응을 조사한 결과 고등어에 대한 반응성은 월등히 높았으나 다른 수산식품에서는 반응성이 거의 없거나 매우 낮게 나타나 고등어에 대한 특이성이 매우 높은 항체임을 알 수 있었다. 또한 분석시 시료의 열 안정성은 $100^{\circ}C$까지 양호하였으며 크림스프, 이유식, 소시지, 소스에 대한 spike test(0.01-0.3%)에서 분석회수율은 각각 104, 101, 54, 0%로 나타났다. sELISA에 의하여 16점의 시판시료 중 고등어의 함유 유무를 조사한 결과, 정성적으로 표시와 일치하는 것은 75%이었다. 그러므로 본 연구에서 개발한 sELISA는 일부 한계가 있기는 하지만, 가공식품 중 고등어를 정성적으로 검출하는데는 효과적으로 활용할 수 있을 것이다.
