Plant growth and pollutants uptake by ryegrass(Lolium perenne L.)grown in a Pb and B[a]P polluted acidic soil developed from red sandstone was studied in a pot experiment.Soil samples treated with Pb at the rates of 0,500,1 000 and 2 000 mg kg^-1 (on a basis of oven dried soil)and B[a]P at 0,12.5,25 and 50 mg kg^-1 were planted with or without ryegrass. The plants were harvested 61 days'after its growth.The contents of Pb and B[a]P in the soil and in the plant shoots and roots as well as plant height and dry mass of ryegrass were determined.Results show ryegrass biomass decreased substantially due to Pb toxicity.In the planted soil 4.7% of the Pb applied and 0.023% of the B[a]P applied was taken up by ryegrass,and about 42.6% of the B[a]P applied was left as residue,whereas in unplanted control soil,50.9% was.The findings suggest that cultivation of ryegrass may help remedy Pb 2B[a]P mixed polluted acidic sandy soil.
