常见鱼类, 贝类的含汞量 (ZT)

(2006-12-27 14:53:34) 下一个

FDA 认为除孕妇，奶妈和儿童外，每周吃 14 ounces 含水银平均在 0.5 和低于 0.5 ppm 的鱼和贝类 (Fresh or frozen tuna, Orange roughy, Mahi mahi, Herring, Halibut, Grouper, Catfish, Cod, fresh or frozen Salmon, Canned tuna, Pollock, Flounder or sole etc) ，其中的水银对健康没有影响。

孕妇，奶妈和儿童每周可以吃 12 ounces (about 3 to 4 servings) 含水银远低于 1 ppm 的鱼和贝类。

"The Occurrence of Mercury in the Fishery Resources of the Gulf of Mexico " Report 2000

Mercury was measured as Total Mercury except for species (*) when only Methylmercury was analyzed.

ND - mercury concentration below detection level (Level of Detection (LOD)=0.01ppm)
N/A - data not available

† The following species have been removed from the tables:

  • Bass (freshwater) – not commercial
  • Pickerel – not commercial

‡ Standard deviation data generated for new data 2004 or later only.
