九龙江河口区夏季反硝化作用初探

Denitrification is an important process mitigating nitrogen(N) pollution in aquatic systems.Water samples in 13 sites throughout the Jiulong River Estuary were collected in July,2010 in a preliminary investigation of the denitrification rate in this area.As end-products of denitrification,dissolved N2 was measured by determining N2:Ar ratios using MIMS(HPR-40),while the concentration of nitrous oxide(N2O) dissolved in water was determined by Purge and Trap-Gas Chromatography.The results showed significant s...
