Following the completion of the sampling of the first two stages, the GeoBBC sampling of the third stage in dry season has been completed. From February 11 to 16, 2023, Professor Zhang Gan, Professor Li Jun, Associate Professor Zhao Shizhen, Xiaofei, Bolong and Zhicheng collected 8 surface sediment samples, 11 large water samples (~ 60L/sample) and 26 small water samples (~ 1L/sample) from the Xinfengjiang Reservoir and the river inlet. The large water samples include 8 surface water samples (2m) and 3 deep water samples (20m or 40m). The small water samples include 19 surface water samples (2m) and 7 deep water samples (20m, 40m and 60m). In addition, We set up 15 passive air samplers (3 samplers*5 sampling sites) and 1 atmospheric deposition sampler.
