龙湾涌铜污染的迁移转化研究

摘要

The transfer and transformation of copper (Cu) in Longwan River in Guangzhou Panyu were investigated.The results indicated that Cu content increased from 0. 0158mg/L in 1996 to 0.0732mg/L in 2000. Analysis demonstrated that the irrigation of the water from Longwan River to the vegetable might contribute to the increasement of Cu in the sediments,agricultural soil as well as vegetables. The industrial and agricultural factors for the Cu pollution were also discussed.%以龙湾涌为例研究了内河涌的铜污染的迁移转化，结果表明工业含铜度水的排放及农业含铜农药和化肥的使用，使得水体中的铜含量大大升高，其年均值由1996年的0.0158/mg·L-1增加到2000年的0.0732／mg·L-1。对河涌底泥、农田表层土和蔬菜等含铜量的研究表明，相当部分的铜迁移至河涌底质，并可能随灌溉向土壤和农作物转移。
