¡ ´˜^E—vŽ| To understand the effect of the NH3 emissions from vehicles, the NH4+ bulk deposition and concentrations of gaseous NH3 and particulate NH4+ were measured at two sites in Saitama prefecture, Japan, one at the roadside of an arterial road (Kounosu), and the other in an agricultural area (Kisai). We observed that the NH4+ bulk deposition and NH3 concentration were significantly increased in Kounosu; the effect of NH3 emissions from vehicles was confirmed. NOx was a primary pollutant mainly emitted by vehicle exhaust in the vicinity of arterial roads, and the relationship between NOx and sum of gaseous NH3 and particulate NH4+ (T- NH4+) was examined. The [T- NH4+/NOx] ratios in Kounosu ranged from 0.08 to 0.23 (average 0.15), and in Kisai they ranged from 0.16 to 0.67 (average 0.39).
