The post-mining area of Dąbrowskie Coal Basin is highly contaminated with toxic metals such as Cd, Pb, and Zn. In our previous research Heuchera cv. 'Purple Petticoats' has shown the ability to Pb uptake and effective transport into leaves. The purpose of this experiment was to check whether the time of cultivation and use of nutrients would change the reaction of plants to Pb uptake in soil with low-level pollution (75 mg·kg-1). Pb content was analyzed in soil and plant tissues. Young plants (11 months old) absorb more Pb but stop it in their roots. Contrarily, plants grown for three consecutive seasons in one place were characterized by BAF~0.5 and TF~0.5. Pb amount in soil on plots where fertilizer was used was reduced by 9%, and without fertilizing by 20%.
