This data is the ammonia nitrogen value, Doc value, anion and cation value of the river water at the outlet of hulugou small watershed from June to August 2012. Data overview: the sampling time of this data is from June 21, 2012 to August 25, 2012. The sampling frequency is once a week. The sampling point is located at the outlet flow weir of hulugou small watershed in the upper reaches of Heihe River. The main monitoring indicators were: Sampling location, sampling time, ammonia nitrogen (mg / L), Doc (mg / L), bicarbonate, carbonate HPO4 -, F -, Cl - NO3 -, SO4 -, al3961 as1890, ba4554, ca3179, cd2288, co2286, cr2677 cu3247, fe2599, K_ 7664、Li6707、Mn2576 、Mo2020 Na5895、Ni2316、P_ 2136、Pb2203、S_ 1807、Se1960 Si2516、Sr4077、Zn2138。
This data set contains the values of ammonia nitrogen, Doc, cation and anion of the river water at the outlet of the watershed.
Data acquisition means: ammonia nitrogen value was determined by hash DR2800 ultraviolet spectrophotometer; doc value was determined by analytikjena multi n / C 3100 total nitrogen and carbon tester; anion value was determined by Swiss Wantong 761 / 813 ion chromatograph; cation value was determined by iris intrepid Ⅱ xspicp-aes.
Good data quality
