Abstract: A greenhouse study was conducted to investigate the uptake and translocation of lead and pyrene in ryegrass (Lolium multiflorum L), cultivated in spiked soil. After ageing, the pots were cultivated with ryegrass seedlings to investigate soil-to-plant transfer characteristics of lead and pyrene. In the spiked soils, the biomass of plants was not significantly lower in comparison with the control, while only lead-spiked soil showed significantly lower (P ≤ 0.05) biomass for plant tissues. Furthermore, the pyrene and lead concentrations in the root tissues were significantly higher (P < 0.01) in the lead/pyrene-spiked soil grown plants than in the control, lead and pyrene-spiked soils.
