通过对新安江（黄山段）浅层地下水17个采样点水样的采集，用碱性过硫酸钾消解紫外分光光度法测定水中总氮含量。结果表明，黄山市浅层地下水总氮含量严重超标的有1个，超标的有9个，符合标准的7个。其最主要的污染源是生活污水、养殖废水及工业污水不达标排放造成这部分水域总氮含量超标。另外一个原因是浅层地下水更新周期较长导致总氮积累的结果。
通過對新安江（黃山段）淺層地下水17箇採樣點水樣的採集，用堿性過硫痠鉀消解紫外分光光度法測定水中總氮含量。結果錶明，黃山市淺層地下水總氮含量嚴重超標的有1箇，超標的有9箇，符閤標準的7箇。其最主要的汙染源是生活汙水、養殖廢水及工業汙水不達標排放造成這部分水域總氮含量超標。另外一箇原因是淺層地下水更新週期較長導緻總氮積纍的結果。

Through collecting water samples from 17 sampling points of shallow groundwater in xin'an river ( huangshan section ) , total nitrogen content in water was detected with a basic potassium sulfate digestion ultraviolet spectrophotometry.The results showed that total nitrogen content of shallow groundwater in Huangshan city exceeded bid badly of 1, exceeded the levels of nine , and conformed to the standards of seven.The main sources of waste water and sewage and industrial sewage made total nitrogen content exceed mark waters.Another reason was shallow groundwater updated with a long cycle lead to total nitrogen accumulation results.
