Closing the STS project on illicit drugs control

2024-01-28 Gan Zhang

On Jan the 26th afternoon, an expert committee came to the institute for the final assessment of our STS (Sci&Technol Service) project on key technologies in illicit drugs control. The committee was led by Professor Mo Cehui (莫测辉) of JNU, joining with professors Lai Senchao (赖森潮) of SCUT, Guo Pengran of Guangdong Institute of Analytical and Testing Technology (郭鹏然，广东省科学院分析测试技术研究所) and Liu Junwen of JNU. The STS project, with collaborators from SYSU, Damo Co Ltd （大陌科技）and Hexin Co Ltd （禾仪质谱）, developed key technologies spanning from wastewater based epidemiology (WBE), passive air sampling (PAS), online VOCs analysis, stable isotopes etc to remit the critical need of the local government/police on the effective control of illicit drugs. The committee members all gave high praise of the outcomes of the project. Liu Xin helped initiating and carrying-out the project, while in the meantime brought up herself as a police lady who works with illicit drug control. Buqing prepared the technical report, Shizhen arranged the event. Despite we have decided to stop dealing with illicit drugs, we would still continue with our endeavor on wastewater-based epidemiology (WBE)!

Soil sampling in Hainan Island

2024-01-16 Gan Zhang

On Jan 8-13, Buqing, Chuanghe and Gan went to the northern Hainan Island for soil sampling. The region contains a great chronosequence of red soil, with thickness up to tens of metres, developed on basalt rocks, of which the corresponding volcanic eruption time spanning from 4 Ma to 10 Ka before present (BP). We are to evaluate the lifetime of black carbon across the geological times. Two local workers joined us to help with digging and coring. In total we have collected 40 soil profiles, at 8 sites each with 5 profiles. It was warm, and there were mosquitos and unknow insects in the jungles. However, the tropical scenery is picturesque, and the flavor of local chicken is wonderful. It is a successful sampling trip, and we are waiting for the fruitful scientific outcomes!
