Other claims from this paper (8)
- Intervention effect Prolonged cultivation (seven weeks) in sulfur-amended sediment increased chromium concentration in aboveground rapeseed biomass by 50% compared with six-week-old rapeseed.
- Intervention effect Sulfur amendment did not significantly affect Cu, Cd or Pb concentrations in aboveground rapeseed biomass.
- Intervention effect The addition of sulfur did not increase heavy metal concentration in the water-soluble fraction of the sediment.
- Intervention effect Prolonged sulfur exposure lowered the uptake of Cd, Cu and Pb by rapeseed.
- Mechanism The lower uptake of Cd, Cu and Pb is likely due to reduced bioavailability of these metals.
- Observation Proportions of bioavailable sediment fractions decreased after prolonged sulfur exposure.
- Intervention effect Heavy metal uptake efficiency by rapeseed did not differ significantly between 300 and 500 mg S/kg of sediment.
- Recommendation The authors recommend sulfur as a useful soil amendment for targeted phytoremediation of chromium-contaminated sediments.
