英文摘要	Stable nitrogen isotope (delta 15N) technology has often been used as a powerful tool to separate nitrogen oxides (NOx) produced by residential combustion (i.e., biomass burning and coal combustion) from other sources. However, the insufficient measurement of delta 15N-NOx fingerprints of these emissions limits its application, especially in North China where residential emissions are significant. This study conducted combustion experiments to determine the delta 15N-NOx of typical residential fuels in North China, including ten biomass fuels and five types of coal. The results showed that the delta 15N of biomass varied between -6.9%o and 2.3%o, which was lower than the delta 15N of residential coal (- 0.2%o-4.6%o). After combustion, the delta 15N of biomass residues increased greatly, while that of coal residues showed no significant upward trend (p > 0.05). The delta 15N-NOx produced by biomass burning ranged from -5.6%o to 3.2%o (-0.4%o +/- 2.4%o), showing a significant linear relation with delta 15N-biomass. Comparatively, the delta 15N-NOx derived from residential coal combustion was much higher (16.1%o +/- 3.3%o), ranging from 11.7%o to 19.7%o. It was not well correlated with delta 15N-coal, and only slightly lower than the estimated delta 15N-NOx of industrial coal combustion (17.9%o, p > 0.05). These observations indicate that the delta 15NNOx of residential coal combustion is a result of the mixture of thermal- and fuel-released NOx. Based on the isotopic characteristics observed in this study, we analyzed the reported delta 15N-NOx, and provided more statistically robust delta 15N-NOx distributions for biomass burning (1.3%o +/- 4.3%o; n = 101) and coal combustion (17.9%o +/- 3.1%o; n = 26), which could provide guidance for scientific studies aiming to quantify the origin of NOx in North China and in other regions.
