evaluation of phytoavailability of heavy metals to chinese cabbage (brassica chinensis l.) in rural soils.this study compared the extractability of cd, cu, ni, pb, and zn by 8 extraction protocols for 22 representative rural soils in taiwan and correlated the extractable amounts of the metals with their uptake by chinese cabbage for developing an empirical model to predict metal phytoavailability based on soil properties. chemical agents in these protocols included dilute acids, neutral salts, and chelating agents, in addition to water and the rhizon soil solution sampler. the highest concentrations ...201425295297
the dynamic growth exhibition and accumulation of cadmium of pak choi (brassica campestris l. ssp. chinensis) grown in contaminated soils.the accumulation of heavy metals, especially cadmium (cd), in leafy vegetables was compared with other vegetables. pak choi (brassica campestris l. ssp. chinensis) is a leafy vegetable consumed in taiwan and its safety for consumption after growing in contaminated soils is a public concern. a pot experiment (50 days) was conducted to understand the dynamic accumulation of cd by pak choi grown in artificially contaminated soils. the edible parts of pak choi were sampled and analyzed every 2-3 day ...201324284350
chemical stabilization of cadmium in acidic soil using alkaline agronomic and industrial by-products.in situ immobilization of heavy metals using reactive or stabilizing materials is a promising solution for soil remediation. therefore, four agronomic and industrial by-products [wood biochar (wb), crushed oyster shell (os), blast furnace slag (bfs), and fluidized-bed crystallized calcium (fbcc)] and caco3 were added to acidic soil (cd = 8.71 mg kg(-1)) at the rates of 1%, 2%, and 4% and incubated for 90 d. chinese cabbage (brassica chinensis l.) was then planted in the soil to test the cd uptak ...201323947715
extractability and bioavailability of zinc over time in three tropical soils incubated with biosolids.phytotoxicity of heavy metal is the primary concern in applying biosolids (sewage sludge) to agricultural land. this study evaluates the changes in chemical speciation of zn in three tropical soils of taiwan measured with sequential extraction over a one-year period. biosolids were applied to the soils at application rates of 10, 50 and 100 mg ha(-1), and correlated diethylene triamine pentaacetic acid (dtpa) and sequential extraction as extract for prediction of zn bioavailability to chinese ca ...200616213570
