氮污染

从减轻区域酸化风险的角度，大气中碱性颗粒的逐步控制和区域氮污染的恶化对未来SO2排放削减提出了更高的要求。

In the future , the control of alkaline particles and exacerbation of regional nitrogen pollution could raise pressure to limit acidification through further SO2 abatement .

C类工程硝化强度弱于A、B两类，但反硝化强度却更强，说明C类工程沉积环境更有利于氮污染的去除。

Nitrification intensity in sediment of the type C was weaker than that of type A and B , while denitrification intensity was stronger , this phenomenon indicated that sediment environment of the type C is more conducive to remove the nitrogen pollution .

随着经济、社会的发展，河流氮污染的问题日益严重，其中的非点源N污染要占相当大的比例。

Along with the economic and social developments , river N-pollution becomes more and more serious . In which , non-point N pollution is occupied sizeable share .

氮污染源不同，氮同位素值（δ15N值）也就不同。

Different nitrate sources have the different δ 15N values .
