| 英文摘要 | Aerosol iodine isotopes are pivotal links in atmospheric circulation of iodine in both atmospheric and nuclear sciences, while their sources, temporal change and transport mechanism are still not well understood. This work presents the day-resolution temporal variation in iodine-129 (I-129) and iodine-127 (I-127) concentrations in aerosols from Xi'an, north-west China, during 2017/18. Both iodine isotopes have significant fluctuations with time, showing the highest levels in winter, approximately 2-3 times higher than in other seasons, but the correlation between I-129 and I-127 concentrations reflects that they have different sources. Aerosol I-127 concentrations are found to be noticeably positively correlated with air quality index and five air pollutants. Enhanced fossil fuel combustion and inverse weather conditions can explain the increased concentrations and peaks of I-127 in winter. The change in I-129 concentrations confirms that the source and level of I-129 in the monsoonal region were alternatively dominated by the I-129-enriched East Asian winter monsoon and the I-129-poor East Asian summer monsoon. The mean I-129/I-127 number ratio of (92.7 +/- 124) x 10(-10) provides an atmospheric background level for the purpose of nuclear environmental safety monitoring. This study suggests that locally discharged stable(127)I and externally input I-129 are likely involved in fine particles formation in urban air, which provides insights into the long-range transport of air pollutants and iodine's role in particulate formation in urban atmosphere. |
