Details | To investigate the distribution of Mg in the Hiroshima Regional Urban Area, concentrations of Mg in the elements were examined. Concentrations of Mg in the eaweeds (n=3) and plants (n=4), which were representative of aquatic and terrestrial elements, respectively, were determined by the inductively coupled plasma atomic emission spectrometry. Ulva pertusa contained Mg the highest among the organisms examined. Concentrations of Mg as well as Ca in the extracts of soils (n=9), sediments (n=4), seaweeds (n=3), and plants (n=12) were measured and determined by a colorimetric method. Concentrations of Mg in the sediment extracts were as high as those of seaweeds in aquatic area, whereas, the concentrations of Mg in the extracts of plants were higher than those of soils in terrestrial area. These two ways of measurement could make a part of the environment, in which humans live, visible and contribute for the evaluation of ecosystem in the Area. |
