Concept:
中國消息:大陸媒體日前曝光廣東近海珠江污染的嚴重情況,重金屬及有機性污染物含量超標,這些污染會累積在魚類等動物體內,人類若大量食用,會危害健康。尤其是生蠔銅元素、鎘元素分別超標740倍和90倍,屬於「重度污染」。
“現有大量的研究表明,珠江口水體和沉積物中很多重金屬和持久性有機污染物含量超標。這些污染物會在水體生物,如魚類、浮游動物等體內積累富集,並且對它們產生毒性危害風險,更為嚴重的是通過食物鏈將毒性放大,危害人體健康。”廣東省化學危害應急檢測技術重點實驗室副研究員郭鵬然博士說。
2010年廣東海洋公報顯示,廣東近海四成入海排污口排放污水超標,16%的近海海域正在遭受污染。2010年珠江八大入海口和榕江、深圳河、東江等主要入海河流攜帶入海的石油烴、砷、重金屬等污染物108萬噸。其中珠江排入海的污染物占總量七成。
