Preliminary Results of PIXE Analysis of Mosses for Air Pollution Monitoring in Hanoi Using Pelletron Accelerator

Abstract: Air pollutionis a major problem in many cities in Vietnam. The existence of heavy metalsin dust particles in the air impacts negatively on human health. There are many different methods to collect dust in the air and analyse the heavy metalsconcentration. The method using mossesas a biological indicator for monitoring air pollutionhas been using widely around the world. This paper presents the preliminary results of using mossfor analysis of heavy metalsin the air in Hanoi by PIXE technique on Pelletronelectrostatic accelerator of the VNU, University of Science (HUS).
