摘　　要：京杭运河(杭州段三堡船闸至塘栖大桥)有砷污染,污染源为杭州硫酸厂。该厂污水进入余杭塘河经勤丰桥汇入运河干流,底质砷污染自勒丰桥向两侧离散呈指数律递减。Arsenic pollutes the Jimghang Canal which comes from Hangzhou sulfuric acid factory. The sewage flows into Yuhangtang River and passes Qinfeng Bridge then to the main canal and the substrate arsenic pollution decreases progressively from Qinfeng Bridge to two sides at descretion.
