摘要
水产品中硼元素本底值背景资料对于判断水产品中是否添加硼砂或硼酸至关重要。采用ICP–MS法测定了广东省南澳岛海水养殖的315份不同水产品中的硼含量,为水产品质量安全检测提供本底值判断依据。结果显示,硼含量(mg/kg)由高到低依次为龙须菜干制品(152.324)、干海带(78.628)、龙须菜盐渍样(31.146)、龙须菜鲜样(24.168)、海洋杂草(18.983)、昆布(16.541)、新鲜海带(6.164)、贝类(5.351)、紫菜(4.541)、养殖区海水(4.311)、牡蛎(3.820)、虾类(3.662)、非养殖区海水(3.532)、螃蟹(3.038)、鲍鱼(2.119)、鱼类(2.056)。海洋藻类利用同化作用富集硼元素,而动物性水产品可利用异化作用将硼元素排出体外。
Boron background values in aquatic product are important to judge borax or boric acid amount added. The boron of 315 aquatic products in Guangdong province Nan＇ ao city were determined by ICP-MS method. An accordance of background value was provided for aquatic products quality and safety testing. Results indicated that the descending order of boron content （rag / kg） was as the follows： asparagus dry products （152.324）, dry kelp （78.628）, asparagus in brine samples （31.146）, asparagus fresh sample （24.168）, sea weed （18.983）, sea-tent （16.541）, fresh kelp （6.164）, shellfish （5.351）, laver （4.541）, water sea within culture zones （4.311）, oyster （3.820）, shrimp （3.662）, sea water without culture zones （3.532）, crab （3.038）, abalone （2.119）, fish （2.056）. Marine algae enrich boron by assimilation, while animal aquatic products move the boron out of body by dissimilation.
