摘 要: | 为监测渤海海域唐山贝类养殖区贝类毒素的污染情况,防止食用贝类中毒事件发生,于2019年10月—2020年9月间,每月持续在渤海海域唐山贝类养殖区采集四角蛤(Mactra veneriformis)、菲律宾蛤仔(Ruditapes philippinarum)、脉红螺(Rapana venosa)、牡蛎(Crassostrea gigas)、青蛤(Cyclina sinensis)、文蛤(Meretrix meretrix)和硬壳蛤(Mercenaria mercenaria) 7种经济贝类样品,采用高效液相色谱–串联质谱(HPLC-MS/MS)法测试了5种腹泻性贝类毒素(diarrhetic shellfish poisoning, DSP)和14种麻痹性贝类毒素(paralytic shellfish poisoning, PSP)。结果显示,在7种经济贝类样品中均未检出DSP。检出的PSP成分包括石房蛤毒素(Saxitoxin, STX)、膝沟藻毒素1 (Gonyautoxin 1, GTX 1)、膝沟藻毒素2 (Gonyautoxin 2, GTX 2)和脱氨甲酰基膝沟藻毒素3 (Ddecarbamoy l gonyautoxin 3, dcGTX 3),其中,GTX 1含量最高且最高值为537.95 μg/kg。不同季节贝类毒素蓄积含量有一定差异,PSP主要集中在4月检出。菲律宾蛤仔、牡蛎、文蛤和硬壳蛤中PSP的检出率分别为11.76%、47.06%、5.90%和8.82%,其他贝类均未检出。PSP总量均低于欧盟及中国的食用安全限量标准800 μg STXeq/kg。应用风险熵值法和点评估法进行食用安全风险评估,显示风险熵值和暴露风险指数均在安全范围内,结果表明,渤海海域唐山贝类养殖区7种经济贝类不存在食用安全风险。
