摘要
黄河水体砷主要来源于黄土高原地区的泥沙．人为污染造成的水体平均含砷量仅达ＰＰｍ级。鱼体残留砷在黄河干流普遍检出．下游鱼体残留砷高于中、上游。鱼体砷残留量与黄河原状水中含砷量呈密切正相关关系，与食物链、鱼体食性及黄河含沙量有密切关系。
The arsenic contain in the water body of the Yellow River mainly sources from the sedimentarising from the Loess Plateau. The arsenic content resulting from pollution caused by human activitiesis only at PPm level. Arsenic residue is commonly found in fish, especially in the dounstream fish. Witha proportional interrelation with the arsenic content in the untreated water of the Yellow River, thearsenic residue in fish directly relates to food chain. feeding habits of the fish and sediment content ofthe river.
