摘要

In order to understand the migration and deposition patterns of pollutants from urban solid waste incineration in the atmosphere on the plateau, we measured the emissions of pollutants (acidic gases, heavy metals) from the waste incineration plant in Lhasa, Qinghai Tibet Plateau. Additionally, we analyzed heavy metal concentrations in the surrounding atmospheric, soil, and vegetation environment. Subsequently, the Gaussian plume model is used to simulate and analyze the pollutants. The survey revealed that pollutant concentrations during incineration is higher at locations closer to the effective source height (198.55 m). Without being affected by terrain during diffusion, pollutants mainly concentrate at distances from 1 km to 3 km, with migration distances extending up to 10 km. Under the influence of terrain conditions during pollutant diffusion, pollutants emitted from waste incineration into the atmosphere are mainly concentrated within a range of 1 to 2 km, and the main impact range of diffusion and migration is also reduced. Overall, pollutant deposit occurred primarily within approximately 2 km of the source and began to declined beyond this distance.
