The invention discloses a monitoring method of persistent organic pollutants in atmospheric particulates based on a particulate continuous monitor. The monitoring method sequentially comprises the following steps: collection of atmospheric particulate samples with a specific particle size range, acquisition of a filter membrane, analysis of the persistent organic pollutants in the atmospheric particulate samples, and calculation of concentration. The monitoring method is rooted in established automatic air quality monitoring networks at home and abroad, creatively uses the particulate continuous monitor which is used for conventional atmospheric particulate monitoring in the monitoring of the persistent organic pollutants such as dioxins, polychlorinated biphenyls and polybrominated diphenyl ether in the atmospheric particulates, so that the accuracy, stability and continuity of monitoring results are ensured, zero additional sampling cost and zero additional energy consumption are realized, and a new way for the monitoring of the persistent organic pollutants in atmospheric fine particulates such as PM2.5 is opened up.
