【摘要】:[目的]了解紹興市售海產(chǎn)品中常見必需微量元素和有毒重金屬的污染水平,為建立海產(chǎn)品中元素污染物數(shù)據(jù)庫提供依據(jù)。[方法]采用微波消解-電感耦合等離子體質(zhì)譜法抽樣檢測了市售海魚、海水甲殼和海水軟體三類共70份海產(chǎn)品中鉛(Pb)、鎘(Cd)、汞(Hg)、砷(As)、銅(Cu)、鋅(Zn)、鎳(Ni)、鉻(Cr)、鋁(Al)、錫(Sn)、銻(Sb)和16種稀土元素共27種元素的質(zhì)量分數(shù)(以下簡稱"含量"),依據(jù)相關(guān)國家標準評價部分元素的超標情況。[結(jié)果]魚類和甲殼類均以Zn的含量最高,中位值分別為4.84和19.3 mg/kg,軟體類以Al含量最高,中位值為21.0 mg/kg;甲殼類和軟體類均以Sn的含量最低,魚類中Sb的含量最低,中位值均為0.001 5 mg/kg;除錫和鉛外,魚類中另外9種非稀土元素含量均明顯低于甲殼類和軟體類;甲殼類和軟體類Cd的超標率分別為40.0%和5.0%。甲殼類和軟體類中16種稀土元素均以鈰(Ce)的含量最高,中位值分別為15.8和115.7μg/kg;魚類中稀土元素以鑭(La)的含量最高,中位值為1.15μg/kg。[結(jié)論]2015年紹興市售海產(chǎn)品中有害元素的總體污染水平較低,但甲殼類中Cd污染較嚴重,需繼續(xù)加強監(jiān)測并采取適當控制措施。
[Abstract]:[objective] to understand the pollution level of common essential trace elements and toxic heavy metals in seafood sold in Shaoxing City, [methods] the microwave digestion and inductively coupled plasma mass spectrometry (ICP-MS) were used to sample and detect marketable marine fish. A total of 70 samples of marine products from seawater crustaceans and sea water mollusks are composed of 70 parts of marine products, consisting of Pb PbPb, CD / CD, Hg HgN, as ~ (2 +), Cu ~ (2 +) (Cu), Zn ~ (2 +), Ni ~ (2 +), Ni ~ (2 +), Cr ~ (2 +), Al ~ (2 +) _ (AlN), Sn ~ (2 +) Sn ~ (2 +), SB ~ ((b)) and 16 rare earth elements ("content"), according to the correlation. [results] the contents of Zn in fish and crustaceans were the highest, The median values were 4.84 mg / kg and 19.3 mg / kg, respectively. The highest content of Al was found in mollusks (21.0 mg / kg), the lowest in crustaceans and mollusks, and the lowest in fish with a median value of 0.001 mg / kg, except for tin and lead. The contents of the other nine non-rare earth elements in fish were significantly lower than those in crustaceans and mollusks, and the exceeding rates of crustaceans and mollusks were 40.0% and 5.0 respectively. The contents of 16 rare earth elements in crustaceans and mollusks were the highest, and the contents of cerium and cerium were the highest in crustaceans and mollusks. The median values were 15.8 渭 g / kg and 115.7 渭 g / kg, respectively. The content of rare earth elements in fish was the highest, with a median value of 1.15 渭 g / kg. [conclusion] in 2015, the total pollution level of harmful elements in seafood sold in Shaoxing was lower, but CD pollution in crustaceans was more serious. There is a need to continue to strengthen monitoring and take appropriate control measures.
