Method for determination of concentrations of heavy metals in soil relates to control of pollution of environment with heavy metals and can be used in agriculture, soil science, ecological investigations, for modeling pollution of medium due to man-caused load and evaluation of ecological safety of territory. The method is in fact that one performs sampling and analyzes the samples of soils with heavy metals, information obtained together with coordinates of points of sampling as fed to inlet block of generalized radial neuro-network with determination of values of concentrations of each metal by respective dependences. After that signal formed by inlet block comes to radial neuro-network where in process of teaching knowledge on main properties of each sample is collected. After that signal comes to output block of neuro-network that forms signals corresponding to values of real concentrations of heavy metals in earth of any point of locality being investigated that is covered with the trained neuro-network. The signals formed come to PC that forms ecological map of heavy metals in soils of locality being investigated. The method provides increase of reliability of objective information on ecological state of region being investigated and simplicity of its realization. |
