“…The NH 3 for Tsukuba and Yurihonjo was taken from EANET data for Tokyo and Ijira, respectively . The NH 3 concentrations at Tokyo were compared with those at Tsukuba, which were almost the same. The NH 3 averaged concentrations at Tsukuba and Yurihonjo were 2.8 ± 0.6 μg/m 3 (1.8–4.4 μg/m 3 ) and 0.8 ± 0.4 μg/m 3 (0.1–1.7 μg/m 3 ), and the f value averaged 0.21 and 0.41, respectively.…”

Ammonia gas (NH 3 ) is an important alkaline air pollutant and a precursor to particulate matter, and its source has been thought to be agricultural, but in recent years, nonagricultural sources have been suspected. In this study, stable nitrogen isotope ratios of ammonium (δ 15 N−NH 4 + ) in fine particulate matter (PM 2.5 ) were measured at a suburban site and a rural site in Japan. Then, the long-term sources of NH 4 + were identified using the δ 15 N−NH 3 and an isotopic mixing model. The results showed that the averaged contribution from nonagricultural sources was 67% at the suburban site and 78% at the rural site. We also reanalyzed NH 3 data collected at the same location. The result showed that the averaged contribution of nonagricultural sources to NH 3 was 39%. This result is reasonable because bottom-up estimates are close to the contribution, and the NH 3 emissions are affected by warm season activities in the rural site. It was first found that the sources vary greatly, depending on the gas and particles. Back-trajectory results suggested that PM 2.5 measured at the rural site was derived from the Asian continent. We inferred that the NH 4 + had been formed on the continent and that these particles thus represent transboundary pollution.

Ammonia (NH3) plays an important role in air quality and atmospheric chemistry, yet studies on the characteristics and impacts of NH3 are limited. Herein, we revealed the spatial distribution of atmospheric NH3, as measured by passive samplers, at three different sites (R1, R2, and R3) in the rural area (livestock environment) of Jeongeup, South Korea, from September 2019 to August 2020. At site R1, the boundary of a large-scale pig farm, dramatically high daily mean concentrations of NH3 were observed (118.7 ppb), whereas sites R2 and R3, located ~1 km from R1, exhibited lower concentrations of 18.2 and 30.4 ppb, respectively. In the rural environment, the monthly NH3 variations showed a peak in June (34.2 ppb), which was significantly higher than in the urban and remote areas. To examine the impact of NH3 from the rural area on a nearby urban area in June 2020, simultaneous measurements were performed using a real-time instrument in Jeonju. When high NH3 events occurred in the urban area in June, the results for the NH3 concentrations and observed meteorological conditions in the rural and urban areas showed that the rural area influenced the NH3 levels in the adjacent urban area.
