On January 11-12, Shizhen and Gan went to Beibu Gulf University (北部湾大学）in Qinzhou (钦州) for the annual meeting of the Field Station of Pinglu Canal (平陆运河河口海湾生态系统野外科学观测研究站), amid which Zhizhen was able to see Xuelin（雪琳) and Hangyi(航毅) who were working in the lab of the university for pretreatment of our water samples collected from the coast of Beibu Bay. Both of them had been working very hard in the lab and Hanyi also on the sampling boat. We met as well Professors Wang Yinghui (王英辉) of Guangxi University and Tang Jianhui (唐朝辉)of Yantai Institute of Coastal Zone CAS, and jointly visited the Centaury Project of Pinglu Canal (平陆运河). It is very excited for us to meet occasionally there!
On January 2-4, Shizhen, Jibin, Chunling and Gan participated the 1st Conference on Environmental Earth Sciences for Young Scholars in Shenzhen. Gan gave a plenary speech on 14CO2 monitoring; and Shizhen introduced her research as a flash show. Jibin manned a poster which was awarded best poster presentation by the conference. We had good talks with many people attending the conference, some of them are of our ‘old’ friends. It is a fantastic meeting for meeting with outstanding young people in environmental geosciences.

On 19 December 2025, the 2025 Annual Academic Exchange Meeting of the National Natural Science Foundation of China (NSFC) Major Project “Geochemical Behavior and Effects of Black Carbon” (GeoBBC) was held in Guangzhou. The meeting was hosted by the Guangzhou Institute of Geochemistry (GIG), Chinese Academy of Sciences.
The meeting was structured into two sessions. The morning session featured an Outstanding Research Achievements Symposium, during which representative high-quality research outputs of the project were presented and discussed. The afternoon session comprised the 2025 Annual Progress Report Meeting followed by an expert review and consultation session, during which project progress was comprehensively evaluated and in-depth discussions were conducted with the advisory panel.
The afternoon session was attended by Zheng Yuanming, Director of Division II of the Department of Earth Sciences, and Xiao Jun, Program Officer, from the National Natural Science Foundation of China. Members of the project’s advisory panel also participated, including Academician Tao Shu (Peking University / Southern University of Science and Technology), Academician Peng Ping’an (GIG), Professors Zheng Mei and Zhu Dongqiang (Peking University), Professor Zheng Junyu (The Hong Kong University of Science and Technology (Guangzhou)), Professor Guo Qingjun (Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences), Professor Liu Xueyan (Institute of Geochemistry, Chinese Academy of Sciences), Professor Pan Bo (Kunming University of Science and Technology), Professor Chen Yingjun (Fudan University), and Professor Liu Chengshuai (South China Agricultural University).
Vice Director Zhu Jianxi of GIG, the leading institution of the project, attended the meeting together with principal investigators and more than 30 core project members from GIG, Fudan University, Southern University of Science and Technology, Nanjing University of Information Science and Technology, and the Institute of Earth Environment, Chinese Academy of Sciences.
Zhu Jianxi delivered the opening remarks on behalf of the host institution, introducing the outcomes of the recent reorganization of national key laboratories at GIG and expressing sincere appreciation to the NSFC and the project advisors for their continued support. Gan Zhang, on behalf of the project team, presented an overview of the project’s overall progress, highlighting major advances in the formation mechanisms of black carbon, its climate effects, evolutionary cycling, and cross-sphere behavior. Subsequently, principal investigators Song Jianzhong, Zhang Yanlin, Wang Junjian, and Zhong Guangcai reported on the annual progress of their respective subprojects and outlined research plans for the coming year.
The advisory experts unanimously agreed that the project has made solid progress and delivered substantial outcomes. They highlighted breakthrough achievements in key areas, including the operational definition of black carbon and its subsets, regional atmospheric black carbon and its light-absorbing properties, and methodological advances in source apportionment. The experts also provided constructive recommendations for the next phase of research. Zheng Yuanming and Xiao Jun fully affirmed the project’s overall performance, reiterated the strategic role of NSFC Major Projects, and expressed expectations for the project’s high-quality advancement and successful completion.
The NSFC Major Project “Geochemical Behavior and Effects of Black Carbon” is led by the Guangzhou Institute of Geochemistry, with joint participation from Southern University of Science and Technology, Nanjing University of Information Science and Technology, the Institute of Earth Environment of CAS, and Fudan University. The project aims to elucidate the formation mechanisms of black carbon; develop consistent quantitative characterization methods across environmental media; reveal its cross-sphere geochemical behavior and evolutionary pathways; clarify atmospheric aging processes and comprehensively assess radiative forcing effects; uncover the impacts of black carbon on surface organic carbon reservoirs and the environmental fate of toxic pollutants; overcome methodological barriers; and innovatively construct and refine relevant theoretical models, thereby enriching the discipline of geochemistry.
By the end of the fourth project year, a total of 143 academic papers had been published, including seven articles in PNAS and Nature family journals, with a first-affiliation rate exceeding 50%. In addition, several early-career researchers trained through the project have received national and provincial talent awards and academic honors.
