On Jan.9,2023, the Air-Omics Squad(“爱米小分队”) had a wonderful party after postgraduate students’ work retrospect meeting to celebrate the great progress of this year’s study and hard work of the teachers and students. We also had Dengxin with us who is a junior student from South China Normal University. We had special Yunnan cuisine at a lovely restaurant. New Year’s greetings to all who read this news. Happy new year to everyone! Wish our group thriving and prosperous!
GeoBBC Sampling in Dry Season mainly includes four stages, and the first two stages have been completed. In the first stage (from 14 Nov. to 26 Nov.), Xiaofei, Bolong and Zhicheng collected the surface water and sediment samples from the main stream of the Dongjiang River (12 sampling sites) and Qiuxiangjiang River (2 sampling sites). In the second stage (from 12 Dec. 2022 to 8 Jan. 2023), the same sampling team collected surface water and sediment samples from Xinfeng River (3 sampling sites), Daxi River (5 sampling sites), Lianping River (6 sampling sites) and Zhongxin River (8 sampling sites). In total, 36 water samples and 25 sediment samples were collected. Among which, basic water quality parameters such as pH, conductivity and ammonia-nitrogen concentrations have been determined. In addition, 28 water samples have been filtered and enriched to obtain particulate matter (PM) and dissolved organic matter (DOM), respectively. Pro. Zhang, Pro. Li and associated Pro. Zhao also participated in this campaign with strategic significance.
In the second stage, Tang Jiao and the GeoBBC sampling team set up 30 passive samplers in the Dongjiang River Basin, mainly distributed in Xinfeng County (4 sampling sites), Lianping County (5 sampling sites) and Dongyuan County (1 sampling site). Three samplers were installed at each sampling site to obtain parallel samples.

From Nov.15 to Dec.21,2022, Yuwei, Yingjian and Chuxin conducted simultaneous sample collection and observation of POPs and POM every day and night at three sampling sites in GIG, Boluo and Heshan Atmospheric Supersite, respectively. Pingyang and Weiru were in charge of CO2 collection and dry and wet deposition in GIG. A total of 737 air samples and 30 deposition samples were successfully collected during this meaningful campaign. This beautiful project logo was designed independently by Weiru and Pro.Zhang also inscribed this logo. (Images 1 below) Let’s enjoy the fascinating scenery captured by our colleagues while sampling!
