Аннотация:In this article, the efficiency of mercury absorption by Sinapis alba was studied when soil was contaminated with mercury at the level of 100 MPC (concentration of metallic mercury in the soil taken from the territory of the Usoliekhimprom enterprise) using chemicals. Monoethanolamine salt of bitioacetic acid, sodium salt with thiosulfuric acid and disodium salt of ethylenediaminetetraacetic acid were used as chemical preparations. Based on the results of the experiment, the coefficients of mercury bioaccumulation and translocation were calculated.
