The DC flowing post-discharge in nitrogen containing mercury traces of about 3.14 ppb was studied in Pyrex tube by emission spectroscopy. The relative populations of N_2 (B ^3 Pi_g), N_2 (C ^3 Pi_u) and N_2^+ (B ^2 Sigma_u^+) states were calculated in the dependence on the post-discharge time in the range of 3 - 40 ms. As the uncontrolled oxygen traces were recorded in the mercury flow the experiment with nitrogen-oxygen mixture was added. The results showed strong quenching of the nitrogen pink afterglow by mercury traces. The kinetic explanation should be done through strong depopulation of level N_2 (X ^1 Sigma_g^+,v = 20) (creation of mercury ^3 P_1 state) and levels N_2 (X ^1 Sigma_g^+, v = 28) or N_2 (A ^3 Sigma_u^+,v = 4) (creation of mercury ^1 S_0 state). Both mercury states are origins of UV light emission (254, resp. 185 nm) that could not be detected in our experimental set up.
