As a matter of fact, air pollutants prediction serves as a key issue for environment analysis in recent years. In consideration of the stochastic motion of the air particles, it is crucial to implement numerical simulation tools to analyze the random effects. With this in mind, random walk is utilized as a typical scheme to simulate the diffusion process incorporated with concepts of Monte Carlo simulations. On this basis, this paper will present a systematical analysis for simulation of pollution diffusion by means of random walk. To be specific, the calculation principle, formulae and process will be demonstrated. Subsequently, the simulation results will be given in the meantime. In addition, the application scenarios will be discussed and illustrate. At the same time, the evaluations of the results will also be presented and the current limitations will be estimated with suggestions for further research. Overall, these results shed light on guiding further exploration of air pollution.
