Assessment of selected tree species as phytoremediation agents in polluted soils.
The study investigates the ability of selected tree species to absorb heavy metals (Pb, Ni, Zn) from polluted soils. Seedlings of Adansonia digitata (P1), Jatropha curcas (P2), and Hildegardia barteri (P3) were transplanted into polythene pots with soils from a dumpsite (T1), highway (T2), industrial area (T3), and farmland (T4), forming a 3x4 factorial experiment replicated five times in a Completely Randomized Block Design. Pre-sowing analysis showed T1 and T2 had the highest Pb and Zn concentrations, T3 had the highest Ni, and T4 had the lowest heavy metal concentrations. After 12 weeks, heavy metal concentrations decreased in all soils. P1 concentrated metals in the root, P2 in the shoot, and P3 in various plant parts, with significant differences between species. P2 was identified as an effective phytoextractor for Pb and Zn (TF > 1), and P3 for Ni. All species showed potential for phytostabilization. The study concludes that these species are viable options for phytoremediation of heavy metals in contaminated soils.
期刊介绍：
The International Journal of Phytoremediation (IJP) is the first journal devoted to the publication of laboratory and field research describing the use of plant systems to solve environmental problems by enabling the remediation of soil, water, and air quality and by restoring ecosystem services in managed landscapes. Traditional phytoremediation has largely focused on soil and groundwater clean-up of hazardous contaminants. Phytotechnology expands this umbrella to include many of the natural resource management challenges we face in cities, on farms, and other landscapes more integrated with daily public activities. Wetlands that treat wastewater, rain gardens that treat stormwater, poplar tree plantings that contain pollutants, urban tree canopies that treat air pollution, and specialized plants that treat decommissioned mine sites are just a few examples of phytotechnologies.
