全球暖化海洋更多毒菌

全球暖化海洋更多毒菌（2007年4月28日）More global warming marine toxin

【明報專訊】水生貝殼類動物如蠔、蜆、青口、帶子等是濾食性生物，容易攝取水中的毒藻，並會積聚在貝類的組織內，尤其內臟部分。貝類的毒素含量，則視乎其攝取的毒藻數量，另外，一些海洋細菌亦會生產毒素。而海水溫度也會增加這種毒素在海洋生物中存在的機會。

Report : shellfish aquatic animals such as oysters, clams, shellfish, such as scallops are filter-feeding organisms, easy uptake of poisonous algae in water, and accumulate in shellfish tissue, in particular visceral part. Shellfish toxin content, depending on its uptake in the number of poisonous algae, and some marine bacteria will produce toxins. And the sea water temperature will increase such toxins in marine organisms exist opportunities.

食物安全中心昨日說，麻痺性貝類毒素是天然存在；中大生化系副教授陳竟明補充，科學界相信全球暖化會增加這種天然毒素在海洋生物中存在的機會，因暖化令海水溫度上升，令海洋細菌生長得更多、更快、更早，包括會生產毒素的細菌，例如副霍亂弧菌，導致海中毒素增加。

Food safety center, said yesterday that PSP is the natural existence; Zhongshan University associate professor of the Department of Biochemistry, Chan King-ming added, the scientific community believe that global warming will increase such natural toxins in marine organisms exist, Order by warming sea temperatures rise, marine bacteria grow more, faster and earlier, including the production of the bacterial toxin. For example, Vibrio cholerae, leading to increased sea toxin.

陳竟明續稱，全球化加強各國貿易來往，海上交通頻繁亦會將毒素擴散，因細菌和藻類也可由船隻帶到另一地區，令各水域生態「大兜亂」。

Chan King-ming said that the globalization of trade between countries to strengthen sea traffic will be frequent toxins spread by bacteria and algae may also be taken to the vessel in another area, the waters "soliciting chaos."

除了貝殼類有麻痺性貝類毒素，雪卡毒素是另外一種來自海洋的毒素。有外國研究指出，全球暖化會增加珊瑚死亡率，導致含雪卡素的海藻大量生長，再透過珊瑚魚的食物鏈累積，傳給人類。

Apart from the shellfish are paralytic shellfish toxin, ciguatera is another kind from the marine toxins. Some overseas studies have indicated that global warming will increase coral mortality, lead to ciguatoxin - with the massive growth of algae, through coral reef fish food chain accumulated to humans.

港扇貝帶子多來自南中國海

香港仔漁業海鮮商會主席陳富明表示，港人食用的扇貝及帶子多來自南中國海，數量佔整體海鮮入口量一成。扇貝形似「蜆殼」，呈黃色，帶子呈深綠色長三角形狀，兩者都在深海底沙面出沒，而帶子較扇貝貴三成。
