Multispectral Control of Ecotoxicity of Waters Using Duckweed (Lemna Minor)

A study was made of the chemical composition of the sludge from electroplating and its environmental impact was evaluated. By X-ray fluorescence spectroscopy, it was established that the sample contains heavy metal oxides and hydroxides and falls under the 3rd hazard class. With the help of the developed tools, experimental studies of toxicity control in aqueous media were carried out by the multispectral method using the test object of the small duckweed (Lemna minor L.). The proposed methods and the developed tools for multispectral environmental monitoring have made it possible to evaluate the complex effect of hazardous waste components on the ecological state of water bodies. The result has been improved management efficiency of ecological safety of water bodies through the development of multispectral methods and technical means of controlling ecotoxicity.
