Abstract

Considering the importance of phytoremediation as an effective method in reducing environmental pollutants, especially heavy metals, an experiment using the split plot in time arrangement with three replications was conducted in this research to study the extent the two heavy metals lead and cadmium were absorbed by ash trees planted in the green space of our country. The experimental treatments included iron sulfate and iron chelate sprays and the control at three different sampling times (start of the growing season, end of the growing season, and the onset of leaf fall). According to the results, the highest lead concentration was observed in the iron sulfate treatment that, of course, was not significantly different from that of the iron chelate treatment. The maximum cadmium concentration belonged to the iron chelate treatment. The maximum cadmium concentration was observed in the treatment with iron chelate. In this treatment, the highest leaf chlorophyll a content was measured,
