| effects of soil amendments on lead uptake by two vegetable crops from a lead-contaminated soil from anhui, china. | previous studies have documented that phosphate compounds of lead (pb) [e.g., pyromorphite pb5(po4)3-(x), where x=oh, f or cl] are comparatively insoluble, and their formation in pb-contaminated soil may be a means of reducing the bioavailability and chemical lability of pb in soil. in this study, the effect of phosphate compound amendments on the bioavailability of pb in a polluted alkaline soil was examined. a pb-contaminated soil was treated with hydroxyapatite (ha), phosphate rock (pr), wate ... | 2004 | 14987865 |
