Professor Wang Lei from Nankai University Delivers an Academic Talk

On January 5, Professor Wang Lei (汪磊) from Nankai University was invited to deliver an academic talk at SKLAET entitled ‘Initial Insights into Biological Exposure Behaviors of Environmental Microplastics’ (环境微塑料的生物暴露行为初探).The talk focused on recent advances in environmental microplastics research and systematically introduced analytical methods, major biological exposure pathways, as well as the associated environmental and health risks of microplastics.

During the talk, Professor Wang highlighted his team’s recent Nature publication, ‘Leaf absorption contributes to accumulation of microplastics in plants.’ This study elucidates the dominant pathways and underlying mechanisms of microplastic uptake by plants, providing new scientific evidence for understanding the transport and accumulation of microplastics in terrestrial ecosystems. In addition, Professor Wang shared insights from his own research experience, including the conceptual framing of the study, research strategies, and reflections on the experience of manuscript preparation and publication.

The talk attracted broad participation from researchers and graduate students at SKLAET and stimulated lively discussions on the impacts of environmental microplastic exposure on physiological functions, as well as on approaches for characterizing and assessing health risks associated with microplastic exposure.

GeoBBC Progress – Phase 3 Dry Season Sampling Completed

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.
