摘要
实验采用高效液相色谱-串联质谱法(HPLC-MS/MS)检测2017—2018年福建中部海域养殖贝类麻痹性贝类毒素(PSTs)。结果表明:2018年采集的贝类样本均未检出麻痹性贝类毒素,2017年采集的贝类样本有17批次检出麻痹性贝类毒素,主要检出成分为脱氨甲酰基石房蛤毒素(dcSTX)、膝沟藻毒素(GTX1、GTX2、GTX3、GTX4、GTX5),脱氨甲酰基膝沟藻毒素(dcGTX2、dcGTX3)也占有一定比例,未发现石房蛤毒素(STX)。2017年福建中部海域链状裸甲藻(Gymnodinium catenatum)暴发事件对该海域养殖贝类的麻痹性贝类毒素有一定影响,其中有毒赤潮对贻贝的影响大于牡蛎,而对缢蛏和蛤类则无影响。
The paralytic shellfish toxins was investigated in farming shellfish samples collected from the middle of Fujian sea-area from the year of 2017 to 2018 by high performance liquid chromatography-tandem mass spectrometry.The results showed that:PST was not detected in the shellfish samples collected in 2018;PST was detected in the 17 batch of shellfish samples collected in 2017,with dcSTX as the most predominant components.Besides,GTX1-5 and dcGTX2-3 could also be detected in the samples.STX was not detected in the samples.The outbreak of Gymnodinium catenatum in the middle of Fujian sea-area had a certain impact on the detection of PST in the shellfish samples from the same area,including a greater impact on the mussels than oysters;but there was no impact on Sinonovacula constricta and Ruditapes philippinarum.
