摘要
分析世博园区水体底泥中氮磷营养盐、硫化物和有机质含量,结果表明,硫化物为(4.51±0.12)mg/kg,有机质为(1.73±0.01)%,氨氮为(206.6±1.2)mg/kg,亚硝酸盐氮为(0.041±0.001)mg/kg,硝酸盐氮为(0.066±0.002)mg/kg,总氮为(0.228±0.002)%,速效磷为(192.3±0.5)mg/kg,总磷为(0.247±0.001)%。运用有机指数评价底泥污染,为0.299±0.005,说明污染较严重。
Nitrogen, phosphorus, sulphide and organic matter(OM) in sediments of the water body of Shanghai Expo Area are studied. Mean concentration of sulphide, OM, ammonia nitrogen, nitrite nitrogen, nitrate nitrogen, TN, AAP and TP are (4.51±0.12)mg/kg, (1.73±0.01)%, (206.6±1.2)mg/kg, (0.041±0.001)mg/kg, (0.066±0.002)mg/kg, (0.228±0.002)%, (192.3±0.5)mg/kg and (0.247±0.001)% respectively. The organic index, used to evaluate pollution in the sediments, is 0.299±0.005. Results showed that the pollution is serious relatively.
