  • 摘要: 依据2009—2014年河北平原浅层地下水硝态氮(NO3--N)监测数据,分析河北平原浅层地下水NO3--N污染状况,并利用氮氧双同位素的方法对地下水中硝态氮的来源进行了示踪。结果表明,2009—2014年河北平原浅层地下水硝态氮平均含量变化范围在0.00~121.50 mg/L之间,总平均值为(18.72±1.55)mg/L,超过美国饮用水标准(10 mg/L)的0.872倍;三个子平原区的SO42-/Cl-差异较大而NO3-/Cl-值相差不大,说明地下水中的氯化物、硝态氮以及硫酸盐有着不同的来源。东部滨海平原区NO3--N含量最大,为31.55 mg/L,已超出美国饮用水标准2.155倍;其次为山前平原区,为16.45 mg/L,超出美国饮用水标准0.645倍;中部平原区的含量最低,仅为4.19 mg/L,未超标。根据同位素的数值进行分析,揭示了东部滨海平原区以及中部平原区的硝态氮来源主要为化粪池废弃物,山前平原区的硝态氮主要来自化肥中的NH4+。
    Abstract: The nitrate-N(NO3--N) contamination of shallow groundwater in Hebei Plain was determined and traced,using nitrogen-oxygen dual isotopes to trace the sources of nitrate,monitoring data were from 2009 to 2014.The results showed that the average values of nitrate-N concentrations were 0.00—121.50 mg/L,the total average was (18.72±1.55) mg/L in the 6 years,it exceeded 0.87 times by the American Drinking Water Standard(10 mg/L).The ratio of SO42-/Cl- was different largely,but the ratio of NO3-/Cl- was little difference,it indicated that those ions had different sources.Every sub-plain had different concentrations of nitrate-N,the largest was 31.55 mg/L appeared in the Eastern Coastal Plain,exceeded 2.16 times by the American Drinking Water Standard;followed was 16.45 mg/L appeared in the Piedmont Plain,exceeded 0.65 times ;the minimum was 4.19 mg/L appeared in the Central Plains,not exceeded.According to the analysis of isotopes values,the nitrate-N was from septic waste in the Eastern Coastal Plain and the Central Plains,and in the Piedmont Plain,it was from NH4+ of fertilizers.
