Phytoremediation of lead (Pb) contaminated soils with Helianthus annuus hyperaccumulator

This dataset contains the results of the Helianthus annuus hyperaccumulator in lead (Pb)-contaminated soils. The experiment parameters were as follows: (1) Pb-contaminated soil + Helianthus annuus, (2) Pb-contaminated soil + biochar (50g/L) + Helianthus annuus, (3) Pb-contaminated soil + biochar (50g/L) + nanobiochar foliar spray (2%), and (4) control soil + Helianthus annuus. The experiment was conducted in a greenhouse on the Gdańsk University of Technology campus. The parameters measured include plant development and survival, photosynthesis parameters, and soil contamination status.
