Atmospheric fine particle monitoring equipment and equipment have achieved initial results

[China Instrument Network Instrument R&D] Recently, the Beijing Municipal Natural Science Fund Committee Office and the Beijing Academy of Science and Technology jointly organized a joint funding project seminar. The seminar was chaired by the relevant leaders of the Research and Development Department of the Beijing Academy of Science and Technology.

The project exchange seminar focused on atmospheric fine particle monitoring and health risk assessment. A total of nearly 20 related scientific researchers from 11 organizations participated in the seminar. Five project leaders from Peking University, Beijing University of Aeronautics and Astronautics, China Center for Disease Control and Prevention, and other units respectively introduced the research progress and phased research results of the project. Among them, the air evaluation model for microscopic particulate matter exposure has been constructed. In the area of ​​fine particle monitoring, a particle measuring instrument with a self-regulating function of humidity and a prototype capable of distinguishing the number of nano-sized fine particles have been developed.

At the meeting, the participating researchers held a lively discussion around accurate monitoring of air fine particulate matter, exposure assessment and intervention mechanism for fine particles, fine particulate matter and human health model, etc. It is recommended that the follow-up work should focus on the following issues: (1 ) Characteristics of fine/ultra-fine particles from different sources and biological toxicological effects; (2) Study of characterization of fine/ultra-fine particles in vivo; (3) Study of biological effects of fine/ultra-fine particles on organisms and animal models (4) Research on the intrinsic mechanism of inhalation of fine/ultra fine particles causing respiratory and cardiovascular system damage; (5) Research and development of related instruments and equipment for the fine and fine particle size classification.
