In this paper, an air pollutant assessment and monitoring system based on arm series-embedded system S3C44BOX module is proposed. On this basis, this paper analyzes the annual data of PM2.5, PM10, CO, NO₂, SO₂, O₃, and other air pollutants of 17 monitoring stations in C City in the past year. The results show that the air pollutants have air permeability. At the same time, meteorological factors, temporal and spatial changes, and air pollution factors are discussed. At the same time, this paper uses literature and expert interviews to determine the performance factors of PPP projects. PPP mode realizes the participation of social capital in infrastructure construction. We identified 34 factors and used a structural equation model to analyze the path of 333 PPP project performance factors. One of the main performance factors is to apply the results of air pollution assessment based on an embedded system to the research of performance factors of PPP project, so that this paper could successfully promote the effective implementation of PPP project. Through the continuous research of embedded system and its application in air pollution evaluation and PPP project performance, it can effectively improve the air pollution evaluation and PPP project performance.

本文提出了一种基于arm串联嵌入式系统S3C44BOX模块的大气污染物评估监测系统。在此基础上，本文分析了PM2.5、PM10、CO、NO ₂、SO ₂、O ₃的年度数据C市17个监测站近一年大气污染物排放情况。结果表明，空气污染物具有透气性。同时讨论了气象因素、时空变化和空气污染因素。同时，本文通过文献资料和专家访谈来确定PPP项目的绩效因素。PPP模式实现社会资本参与基础设施建设。我们确定了 34 个因素，并使用结构方程模型分析了 333 个 PPP 项目绩效因素的路径。主要绩效因素之一是将基于嵌入式系统的大气污染评价结果应用于PPP项目绩效因素的研究，从而成功推动PPP项目的有效实施。
