摘要:

海产品是人们喜爱的食品之一,然而随着工业的迅猛发展,排放到近海海域的有毒元素汞(Hg)、铅(Pb)和砷(As)已经威胁到海产品的食品安全。本文通过对2005—2015年欧洲(意大利、挪威等)、中东地区(土耳其、伊朗等)及中国近海海域海产品中Hg、Pb和As含量对比分析,结果得出:1)中东地区及中国近海海域海产品Hg含量有部分超标。2)中东近海海域海产品Pb含量远高于中国近海海域和欧洲近海海域并大部分超标,其中双壳贝类Pb含量普遍高于鱼类。3)欧洲(意大利、挪威等)近海海域海产品As含量显著高于其他地区并大部分超标。4)中国北方沿海地区的双壳贝体内Hg含量普遍大于东南沿海地区。

Abstract:

Seafood is one of people’s favorite foods. With the rapid development of industry, the industrial emission of the
toxic elements Hg, Pb and As has been a threat to the safety of seafood. In this paper, Hg, Pb and As contents in seafood
from Europe (Italy and Norway), the Middle East (Turkey and Iran) and some coastal areas of China collected during
2005–2015 are compared. The results show that: 1) Hg content in some seafood from the Middle East and China’s coastal
areas exceeds the maximum allowable limit; 2) Pb content in most seafood from the Middle East is much higher than in that
from coastal areas in China and Europe, and bivalves have higher levels of Pb content than fishes; 3) As content in most
seafood from European (Italy and Norway) coastal areas is significantly higher than in that from other coastal areas and
exceeded the maximum allowable limit; 4) Hg content in all investigated bivalves from coastal areas in northern China is
higher than in those from coastal areas in southeast China.

Key words: seafood, Hg, Pb, As
