Description
In this study, an urban soil was amended with some commonly used fertilisers and effects on the concentrations and bioavailabilities of potentially toxic metals (PTM) studied through plant uptake experiment. A suite of PTM (As, Cd, Cr, Cu, Fe, Mn, Ni, Pb, U, and Zn) was quantified in sample digests and extracts using inductively coupled plasma mass spectrometry. Uptake of PTM by bean plants grown in 2% chicken manure amended soil, and by radish grown in 2% chicken manure, 0.2% growmore fertiliser or 2% chicken manure + 0.2% growmore fertiliser amended soil were studied. The PTM concentrations in control bean plant exceeded those in bean plants grown in chicken manure amended soil, and a similar trend was observed for radish, suggesting that chicken manure addition can decrease PTM bioavailability to plants. Addition of growmore fertiliser resulted in plants with similar PTE burden to control plants. It was found that EDTA-extraction of soil generally overestimated actual plant uptake of PTM.Keywords: Metals, Bioavailability, Soil, Accumulation, PTM
