美國地質測量局最新的一項研究表明,在對美國近 300 多條河流中的魚取樣測量後發現,所有的魚樣中都有汞。四分之一的魚樣超標(美國環保局的標準是 0.29 ppm 。 1 ppm= 百萬分之一) .
汞汙染主要來自燒煤,煤中的汞隨煙進入大氣,後又通過大氣降水和地表徑流到達河流。經過微生物的作用,成為有毒的甲基汞,進入食物鏈。因為汙染物在食物鏈中一環一環地富集,處於水生食物鏈頂端的凶猛捕食魚類一般含汞量最高。汞對神經係統有害。
(釣魚的人要注意了:是不是越笨的魚越好釣?笨魚的神經係統受汞毒害較多。)
那什麽樣的海鮮河鮮含汞較低呢?食物鏈底端的和年幼的生物一般含汞量較低。如沙丁魚是較安全的,因為它們吃藻類生長。小魚,小蝦,河蚌,扇貝也可安全食用。美國環保局建議每星期食用低汞水產品不超過 12 盎司(七兩),汞含量較高的水產品不超過 6 盎司 (三兩)。
兒童,懷孕婦女,或哺乳的母親不應該吃任何含汞量高的魚,如鯊魚 (shark) ,旗魚 (swordfish) ,鯖魚 (king mackerel), 或方頭魚 (tilefish) 汞含量較高。
人類真是太作孽了,大自然的魚都被汙染成毒魚了!

• 請問帶魚怎樣?我媽在國內愛吃。 -黃桷樹- ♀ (0 bytes) (21 reads) 8/22/09 |
• 根據聯合國的報告 -北美老農- ♂ (598 bytes) (137 reads) 8/23/09 “Large predatory fish, such as king mackeral, pike, shark, swordfish, walleye, barracuda, scabbard and marlin, as well as seals and toothed whales, contain the highest average concentrations. While large tuna typically have levels of mercury that are similar to other large predatory fish, data indicate that the levels usually seen in canned tuna are substantially lower. This results from the fact that the tuna currently used for canned tuna are those of smaller size.” 帶魚是一種肉食性魚類,但體型不大,它的汞含量相對其它海魚來說可能會是中等。日本幾年前的數據也表明帶魚汞含量是中等的。 |

• 兩細節 -jaydad- ♂ (1073 bytes) (83 reads) 8/23/09 1) 蛋白汙染不是脂肪汙染-unlike dioxins or PCBs, methylmercury (the main organic form as found in fish and other animals) does not accumulate in fat tissue, instead, through double sulfur bond it binds to protein (fish meat), therefore throwing away skin and fat does not help lower mercury content 2) 排毒很慢很難巰基是關鍵-elimination of methylmercury is so slow that usually kids end up accumulating mercury to toxic level. Now that you realize the problem, you can help shift the balance (a little tiny bit) toward elimination, through food selection. The removal of methlymercury in body requires glutathione. Unfortunately, we can't take glutathione pill or glutathione injection because it is quickly degraded. We can provide the body with plenty of precursors to synthesize glutathione, in the form of mercapto (-SH) containing amino acid, cysteine. Asparagus, avocado, and garlic are easy choices. For adults, milk thistle and alpha lipoic acid are two commonly available supplements that are known to boost body (liver)'s glutathione level. |
