Abstract:In order to effectively monitor the VOCs hazard status and prevent the development of hazards，a VOCs hazard assessment method based on system dynamics was proposed.According to the types of VOCs hazard objects， the system dynamics models of atmospheric environment subsystem， surface natural ecological environment subsystem and human health subsystem were established， and the economic losses of the three subsystems caused by VOCs were used to measure the degree of VOCs hazard.In the case study，the VOCs hazard degree of city A from 2013 to 2025 was evaluated and predicted，and it was found that the VOCs hazard of city A was relatively serious from 2013 to 2016，serious from 2017 to 2021，and very serious in 2022，and it would last until 2025 or even longer.The results showed that the model was suitable for quantitative calculation of VOCs hazard degree in a certain time series，and it was helpful to understand the harmful consequences of VOCs on the environment and human health.
