The suitability of various analytical and sampling methodologies for the determination of the environmental impact of a test scale MHD power generation facility is evaluated. Media which were sampled included airbourne particulates, soils, vegetation and natural waters. Analytical techniques examined include plasma emission and atomic absorption spectrometry and ion chromatography. Except in the case of the sampling of particulates with moss ball samplers, the analytical and sampling methodologies can be integrated in such a manner so as to maximize precision and thereby facilitate the statistical evaluation of impact effects.
