Open Access Policy refers to a set of principles and guidelines aimed at providing unrestricted access to scholarly research and literature. It promotes the free availability and unrestricted use of research outputs, enabling researchers, students, and the general public to access, read, download, and distribute scholarly articles without financial or legal barriers. In this response, I will provide you with an overview of the history and latest resolutions related to Open Access Policy.
This research used the calculating method of dry deposition to estimate ammonia (NH3) dry deposition value and evaluate its trend in 5 recent years. The results indicate that NH3 concentration is from 1.5 to 11ppb and sites in Southern Vietnam have higher NH3 gas concentration than Northern Vietnam. The high emitted concentration in September is at the Can Tho site in 2019 and in March at the Ha Noi site in 2023. The 2021 year has the highest NH3 dry deposition with 35.59 kg/ha/ year and the 2023 year has the lowest NH3 dry deposition with 24.4... kg/ha/year. Hoa Binh site has the highest NH3 dry deposition and a strong increase in December 2021. The Can Tho site has high NH3 dry deposition in most of the years from 2019 to 2023. The rural site reveals higher NH3 dry deposition than other sites due to agricultural activities. Medium NH3 dry deposition in 2021 is higher than other years with the biggest gap between years of NH3 dry deposition. The decreasing trend of NH3 dry deposition occurred from 1999 to 2023 and there is a strong increase in 2021, then it is sharp decrease to 2023. The decreasing trend reveals a perfect signal for improving environmental quality in good monitoring with NH3 dry deposition.

This research used the calculating method of dry deposition to estimate SO2 dry deposition value and evaluate its trend in 5 recent years. The results indicate that SO2 emission at Northern sites is more changing than Southern ones in months by affecting meteorology and weather. Summer and autumn seasons have SO2 emitted concentrations higher than other seasons in 2019, 2020, and 2022 year at Yen Bai, Hoa Binh, and Ha Noi stations. The 2021 year has the highest SO2 dry deposition and the 2019 year has the lowest SO2 dry deposition in 5 recent y...ears. The Hanoi site has the highest SO2 dry deposition value from 2019 to 2022 year. Hoa Binh site has the highest SO2 dry deposition at 2.45 kg/ha/year in 2023. High SO2 dry deposition occurs normally in the summer and autumn (from April to August). Southern sites have lower SO2 dry deposition amounts with not much change than the Northern sites of Vietnam. The increasing trend of SO2 dry deposition happened from 1999 to 2023 year and it increases sharply from 1999 to 2021. Therefore, SO2 dry deposition will have a light-increasing trend in the future.
