摘要: Abstract Chelate-assisted phytoextraction with biodegradable chelants has been demonstrated as an efficient method to enhance heavy metal remediation efficiency by plants, while there is little available information on phytostabilization. A pot experiment was conducted investigate the effects of [S,S]-ethylenediaminedisuccinic acid (EDDS) and nitrilotriacetic (NTA) plant growth Pb accumulation phytostabilizer Athyrium wardii (Hook.) grown in contaminated soils explore feasibility chelate-assisted Greater adverse biomass under high EDDS treatments were observed than NTA treatments. Significant increase shoot concentrations A. wardii noticed increasing dosages, induced higher NTA. Moreover, root 1.18–1.28-time treatments, a peak value at 2 mmol kg −1 Shoot accumulations significantly increased caused 1.44–1.6-time Root Maximum (155.5 mg ) found 14th day. Higher BCF values lower TF compared Available soil 7th day then gradually decreased Soil pH slightly dosages. Therefore, phytostabilization could be feasible way .
