COMPARISON OF THE TOXICITY OF DETERGENTS IN INTERACTION ON LEGUMINOUS CROPS IN THE BIOTEST

The bioeffects of detergents under bioassay conditions were studied. The test objects were: Lepidium sativum L. (watercress), Lens culinaris M. (lentils), Phaseolus vulgaris L. (white beans), and Vigna radiata L. (mung bean). The experiment consisted of 19,200 seeds. The concentration of detergents used in the work were: 0 g/l control; 0.05 g/l; 0.3 g/l; 3.1 g / l. Observations were made on the 6th day. Incubation of organisms occurred at 19 ± 1°C. The plants showed different tolerance to contamination. The toxic effect affected all plants. The detergents suppressed plant seedlings in growth and development. The average length of seedlings was calculated and then the results were processed using statistical methods. Plants P. vulgaris, L. culinaris and L. sativum were suitable as organisms for assessing the toxicity of chemicals. The information about the high tolerance of V. radiata is of interest in connection with the development of technologies for bioremediation of polluted areas of the environment. Researches of the toxic effects of detergents provide new material for the study of environmental pollution. They increase attention to the problem of contamination with this class of substances.
