To explore how anthropogenic activities affect HONO formation, we conducted comprehensive observations in Beijing. During clean periods with a 53 % drop in Traffic Performance Index, HONO, CO, and NO2 levels decreased by 2–3 times compared to polluted periods. Emission reduction simulations showed that a 50 % NOx reduction could lower HONO by up to 46.3 %, indicating that reducing anthropogenic activities significantly suppresses HONO formation and provides direct evidence for pollution control.
