Multispectral Control of Ecotoxicity of Waters Using Duckweed

Abstract

With an improved method and means of control multispectral studied the combined effect of industrial waste on the ecological condition of water bodies. The proposed method consisted in examining the surface of a sample of the aquatic environment covered with floating macrophytes (small duckweed (Lemna minor L.).), which were used for biotesting. At the same time, by studying the array of multispectral images of the object, the object surface was segmented into zones corresponding to damaged and undamaged duckweed leaves. The paper gives an example of testing an aquatic environment contaminated with wastes of galvanic production and determined its composition using X-ray fluorescence spectroscopy. The proposed method and tool made it possible to assess the ecological state of water bodies, taking into account the synergistic interaction of chemicals.
