Other claims from this paper (12)
- Intervention effect 0.5, 1 and 2 mmol/kg EDTA and DTPA increased biomass of ryegrass.
- Intervention effect 0.5, 1 and 2 mmol/kg EDTA and DTPA increased nutrient (N, P, K, Ca and Mg) content.
- Intervention effect 4 mmol/kg decreased biomass of ryegrass.
- Intervention effect 4 mmol/kg decreased nutrient (N, P, K, Ca and Mg) content.
- Intervention effect EDTA and DTPA significantly enhanced contents of Zn in ryegrass versus control.
- Intervention effect EDTA and DTPA significantly enhanced contents of Pb in ryegrass versus control.
- Observation Pb content in ryegrass root reached a maximum of 2730.54.
- Observation Pb content in ryegrass shoot reached a maximum of 2484.42 mg/kg.
- Observation Zn content in ryegrass root reached a maximum of 2428.37.
- Observation Zn content in ryegrass shoot reached a maximum of 2010.43 mg/kg.
- Intervention effect EDTA and DTPA enhanced ryegrass translocation ratio.
- Recommendation The authors see EDTA and DTPA as promising for ryegrass remediation of Pb and Zn contaminated soil, while urging caution about environmental risks.
