獐子岛附近海域沉积物中氮和磷的分布来源及污染风险评价
Distribution,Source and Pollution Risk Assessment of Nitrogen and Phosphorus in Sediments of the Zhangzi Island,the North Yellow Sea
摘要
Abstract
Objective]To evaluate the source and pollution risks of nitrogen and phosphorus in the Zhangzi Island area,the North yellow sea,their speciation and distributions of nitrogen and phosphorus in surface sediments were analyzed.[Methods]The contents of total nitrogen (TN)and total phosphorus (TN)with their speciation in 13 surface sediments of the Zhang-zi Island were studied by K2 S2 O 8 oxidation and HCl extraction.[Results]Results suggested that TN and TP contents ranged from 0.1 92 to 1.357 mg/g and 0.302 to 0.489 mg/g,re-spectively.Organic nitrogen (ON)and inorganic phosphorus (IP)were the main forms,ac-dexes of total P (S p )were below 1 whereas single standard indexes of total N (S N )ranged from 0.35~2.47.[Conclusion]Nitrogen source in sediments of the Zhangzi Island was from the mixture of terrigenous and marine autogenic sources,whereas phosphorus was mainly from terrigenous sources.The sediments of Zhangzi Island was polluted by nitrogen.关键词
