摘要： As the amount of reactive nitrogen (N) generated and emitted increases the amount of N deposition and its contribution to eutrophication or harmful algal blooms in the coastal zones are becoming issues of environmental concern. To quantify N deposition in coastal seas of China we selected six typical coastal sites from North to South in 2011. Concentrations of NH3, HNO3, NO2, particulate NH4+ (pNH(4)(+)) and pNO(3)(-) ranged from 1.97-4.88, 0.46-1.22, 3.03-7.09, 2.24-4.90 and 1.13-2.63 mu g Nm(-3) at Dalian (DL), Changdao (CD), Linshandao (LS), Fenghua (FH), Fuzhou (FZ), and Zhanjiang (ZJ) sites, respectively. Volume-weighted NO3--N and NH4+-N concentrations in precipitation varied from 0.46 to 1.67 and 0.47 to 1.31 mg N L-1 at the six sites. Dry, wet and total deposition rates of N were 7.8-23.1, 14.2-25.2 and 22.0-44.6 kg N ha(-1) yr(-1) across the six coastal sites. Average N dry deposition accounted for 45.4% of the total deposition and NH3 and pNH(4)(+) contributed to 76.6% of the dry deposition. If we extrapolate our total N deposition of 33.9 kg N ha(-1) yr(-1) to the whole Chinese coastal sea area (0.40 million km(2)), total N deposition amounts to 1.36 Tg N yr(-1), a large external N input to surrounding marine ecosystems.
