The paper indroduce the course of emergency monitoring & treatment on the arsenic pollution accident in the Dasha river. In the early of the emergency,the pollution responds team took effective measures successfully to control the diffusion of pollution.. In the meantime stopping the current, screening monitoring and treatment have been done. The area and concentration degree of pollution were clear through multi-media monitoring and the data offered fundamental support to treatment work. The determination results showed that precipitator and oxidizer made large of arsenide deposit dropping down to the riverbed and the polluted water in river became achieving the quality standard. The deposition including As will be cleaned up from the river and be treatmented deeply later. The multi-media determination of As in water, sedment,underground and plants will be continued until latent harm dispear.
