胶州湾贝类体内有毒有害物质污染状况分析

摘要

通过近3年青岛胶州湾贝类中有毒有害物质的抽样调查,了解其食用安全性.从胶州湾34个养殖单位采集贝类,近300多个样品.检测菌落总数、大肠杆菌、麻痹性贝类毒素、腹泻性贝类毒素、铅、铜、镉.结果表明,麻痹性贝类毒素、腹泻性贝类毒素、铅、镉、菌落总数等项目均未检出,符合食用安全标准,但微生物指标大肠杆菌超出规定值范围.本研究根据对胶州湾水域贝类体内有毒有害物质残留的监控调查,采用贝类质量等级划分评价指数法(Sj)对养殖贝类质量进行评价和探讨,说明胶州湾贝类基本符合国家食用安全标准,但应随时注意胶州湾水域的污染状况与变化,确保水产品的食用安全.%To investigate the food safety risk, toxic and harmful substances in shellfish ofJiaozhou Bay,Qingdao, was determined and analyzed for three years. Nearly 300 shellfish samples in 34 culture zones in Jiaozhou Bay were collected,and the total number of bacterial colony, Escherichia coli, paralytic shellfish poisoning (PSP), diarrheic shellfish poisoning (DSP), lead, copper, and cadmium were determined. The total number of bacterial colony, PSP, DSP, lead and cadmium were not detected, indicating that these shellfish met the safe standard for edible seafood. However, the microbial indicator such as E. Coli exceeded the standard. According to the monitoring and the assessment results following the cultured shellfish quality index method (Sj) , the shellfish in Jiaozhou Bay meets the national food safety standard. However, more attention should be paid to the pollutants in seawater of Jiaozhou Bay,in order to ensure the sea food safety.
