目的:了解深圳市海域贝类腹泻性毒素的污染状况。方法:于2007年8月~2008年7月间,逐月采集深圳市大亚湾、大鹏湾海域的贝类,分别采用酶联免疫测定法和小鼠生物法对其腹泻性贝类毒素含量进行分析。结果:两种方法一致性较好,其中酶联免疫测定法灵敏度较高,所调查的168份样品共有25份超出限量标准;腹泻性毒素存在一定的分布特征,夏秋季含量高,消化腺的含量高于贝肉,但两海域分布差异不明显。结论:深圳市大亚湾、大鹏湾海域的贝类存在一定程度的腹泻毒素污染,应加强对水产品的监测和毒素危害的宣传,确保食用安全。
Objective: To understand the pollution status of shellfish diarrhea toxins in Shenzhen sea area. Methods: From August 2007 to July 2008, shellfish collected from Daya Bay and Dapeng Bay waters of Shenzhen were collected monthly. Enzyme-linked immunosorbent assay (ELISA) and mouse bioassay were used to detect the content of diarrheal molluscicides analysis. Results: The consistency of the two methods was better. The sensitivity of enzyme-linked immunoassay was higher. A total of 25 out of 168 samples investigated exceeded the limit. Diarrheal toxins had certain distribution characteristics, high content in summer and autumn, digestive gland Content is higher than shellfish meat, but the difference between the two sea areas is not obvious. Conclusion: Shellfish in the Daya Bay and Dapeng Bay waters of Shenzhen have some degree of diarrheal toxin contamination. Monitoring of aquatic products and promotion of toxin hazards should be strengthened to ensure food safety.
