Accumulating capacity of different varieties of rapeseed under conditions of anthropogenic pollution of soils by heavy metals

The results of a study of the content of heavy metals in the soil, underground and elevated parts of three varieties of rapeseed grown on soil samples from reference and anthropogenically disturbed sites are presented. Under the conditions of increasing chemical pollution, a decrease in the level of accumulation and transition of heavy metals has been established, which indicates the presence of protective mechanisms that begin to work in the area with high content of toxicants in the soil. According to a set of indicators characterizing the phytoremediation potential (resistance to loads, accumulating abilities), the Highlight variety is preferable for phytostabilization of sites contaminated with heavy metals.
