| 英文摘要 | Identifying the inflection points and main influencing factors for arsenic (As) accumulation in Pteris vittata L. under field conditions is important to improve the phytoremediation efficiency. In this study, data on the entire growth cycle (270 days) of P. vittata over a year were recorded through a field trial. The results showed that the As accumulation characteristics of P. vittata were obviously different from those observed in greenhouse experiments. The aboveground biomass of P. vittata began to stabilize on day 180; the As concentration increased to a peak on day 90 and subsequently declined until day 180. The As accumulation was 318.11 g/hm(2) after 120 days, reaching 96.7% of the highest value predicted by the logistic model. The results indicated that soil humidity is the key influencing factor for As accumulation by P. vittata. Increasing the soil humidity can substantially improve the As extraction efficiency. Based on the results of As accumulation in P. vittata, it could be suggested that the effect of As efflux on P. vittata was not significant. According to theoretical calculations, the total As loss caused by rainfall leaching accounted for less than 2.2% of the total As accumulation. The parameters obtained herein are significant for guiding the remediation of As-contaminated soils under similar climatic conditions. (C) 2021 Elsevier B.V. All rights reserved. |
