Conclusions:Method allows for– Quantitative trapping of all 4 arsines down to a few ng(LOD=3.8ng),– Identification of all 4 species,– Sampling of environmental matrices (eg. Rice paddies,volcano fumes, hot springs etc…)– Determining key conditions for As volatilization.Method is simple, robust and can be easily deployedin the field where the real importance of Asvolatilization could be assessed.To be tested in the field…
