Challenges of High Time Resolution Direct Observation of Aerosol Metal Elements in the Field by Using Gas-Conversion ICP-MS

摘要

Direct mass spectrometric analysis for inorganic elements of atmospheric aerosols has become possible by using a gas converter coupled with inductively coupled plasma mass spectrometry (ICP-MS). This versatile and novel analysis technique would make us possible to assess more about source, transport, mixing and modification of the atmospheric aerosols. However, the opportunity of open field observation experiments has been so far limited. In this presentation trials using this novel approach at the open field for a week are briefly described. On the other hand, it is a current important task to reveal the environmental dynamics of the Fukushima radioactive aerosol resuspension. So, the application of the present technique to the field observation in the contaminated area of Fukushima prefecture has been challenged.
