【摘要】：[目的]调查福建沿海市售海产贝类中微囊藻毒素[MCs(MC-RR、MC-YR、MC-LR)]的污染状况。[方法]于2015年夏季分别在福建省厦门、莆田、福州、宁德等四个沿海城市采集市售4种海产贝类(花蛤、紫贻贝、嚑蛏、牡蛎)共80份,采用高效液相色谱-二极管阵列法测定海产贝类中MC-RR、MC-YR、MC-LR含量,并对不同城市海产贝类污染状况进行比较。[结果]检测的80份海产贝类样品中,MCs的总体检出率分别为50%、69%、44%,4个地区MC-LR检出率差异有统计学意义(χ~2=20.064,P0.001)。4个地区的海产贝类全部检出MC-YR,4个地区的嚑蛏、牡蛎中均检出三种MCs。宁德地区嚑蛏平均总MCs污染水平最高,为0.312μg/g,莆田地区牡蛎平均总MCs污染水平最高,为0.316μg/g。[结论]福建沿海城市市售4种海产贝类存在不同程度的MCs污染。
[Abstract]:[microcystin [MCs shellfish in the sale to Fujian coastal city survey (MC-RR, MC-YR, MC-LR). The method of pollution]] in the summer of 2015 in Fujian province Xiamen, Putian, Fuzhou, Ningde and other four coastal city collected from 4 commercial shellfish (Zi Yibei, rest clam, razor clam, oyster a total of 80 copies) by high performance liquid chromatography diode array method for the determination of shellfish in MC-RR, MC-YR, MC-LR content, and the situation of shellfish contamination of different city. Compared the results of 80 shellfish samples] detection, MCs total detection rate was 50%, 69%, 44%, 4 MC-LR area detection rate difference was statistically significant (~2=20.064, P0.001).4 in the shellfish all detected MC-YR, 4 regions were found in the rest of oyster clam, three MCs. Ningde area average total MCs pollution level rest constricta is highest, 0.312 g/g, the average total area of Putian oyster MCs pollution The highest level is 0.316 mu g/g.[Conclusion] 4 kinds of marine shellfish sold in Fujian coastal cities have different degrees of MCs pollution.

【正文快照】： 蓝藻类广泛分布在自然界中,其中铜绿微囊藻所产生的具有肝毒性的微囊藻毒素(microcystins,MCs)已被确认为是引起肝癌的三大主要环境因素之一[1]。铜绿微囊藻是淡水种类生物[2],但自1995年首次报道铜绿微囊藻在广西廉州湾及北海银滩附近海域形成赤潮后,又于2004年在廉州湾海域
