摘要：

长期的人类活动导致砷（As）在土壤中大量积累，对生态环境和人体健康构成严重威胁，迫切需要修复。通过将谷氨酸二乙酸四钠（GLDA，10%）、蜈蚣草水提取物（10%）和茶皂素（4%）以不同比例混合形成复合型植物源活化剂作为试验材料，以As污染的尾矿区土壤作为研究对象，根据土壤模拟和盆栽试验，研究不同配比方案的复合型植物源活化剂对土壤中As的生物有效态含量、供试植物蜈蚣草（Pteris vittata）生物量和提取As的影响，筛选出复合型植物源活化剂最佳的配比方案。研究结果表明，在土壤模拟试验中，复合型植物源活化剂处理土壤中残渣态As的质量分数显著降低，而生物有效态As质量分数显著升高，将残渣态转化为生物有效态，在GST7（7:12:1）处理条件下，生物有效态As的质量分数达到最大，较对照组（CK）提高了40.80%。盆栽试验中，复合型植物源活化剂处理蜈蚣草生物量随GLDA比例升高和茶皂素比例降低，呈现先升高后降低的趋势，在GST6（6:12:2）处理时达到最大，为3.58 g·plant^-1，较CK提高了45.21%。蜈蚣草中As的质量分数显著升高，且随GLDA比例升高和茶皂素比例降低逐渐升高，在GST7处理时蜈蚣草地上部和根部As的质量分数达到最大，为738.30 mg·kg^-1和281.20 mg·kg^-1，较CK提高了40.17%和22.63%。蜈蚣草对As的提取量和去除率变化趋势与其生物量变化一致，呈现先升高后降低的趋势，在GST6处理时达到最大，其值为1795.10 μg·plant^-1和0.59%，是CK的1.85倍和1.90倍。综合表明复合型植物源活化剂的配比方案为GST6（6:12:2）时蜈蚣草的修复效果最佳，可作为一种新的As污染土壤的植物修复策略。

Abstract:

Long-term human activities have led to a large accumulation of arsenic (As) in soils, which poses a serious threat to the ecological environment and human health. Contaminated soil urgently needs to be repaired. In this study, the compound plant derived activator formed by mixing L-Glutamic acid, N, N-bis(carboxymethyl)-, sodium salt (GLDA, 10%), water extract of Pteris vittata (10%) and tea saponin (4%) in different proportions was used as the test material, and the tailings soil polluted by As was used as the research object. According to the soil simulation and pot experiment, the effects of complex plant derived activator with different proportions on the bioavailable content of As in soil, the biomass of Pteris vittata and the extraction of As were studied. Subsequently, the best proportion of complex plant derived activator was selected. The research results indicated that in the soil simulation test, the mass fraction of residual As in soil treated with plant-based activators decreased significantly, while the mass fraction of bioavailable As increased significantly, transforming the residual state into a bioavailable state. Under the treatment condition of GST7 (7:12:1), the mass fraction of bioavailable As reached the maximum, which was 40.80% higher than the control group (CK). In the pot experiment, the biomass of Pteris vittata increased primarily and then decreased with the increase of GLDA ratio and the decrease of tea saponin ratio. When treated with GST6 (6:12:2), the biomass of Pteris vittata reached the maximum value, 3.58 g·plant^-1, which was 45.21% higher than CK. The mass fraction of As in Pteris vittata increased significantly, and gradually increased with the increase of GLDA ratio and the decrease of tea saponin ratio. When treated with GST7, the mass fraction of As in the above-ground part and root of Pteris vittata reached the maximum values, 738.30 mg·kg^-1 and 281.20 mg·kg^-1, respectively, which were 40.17% and 22.63% higher than those of CK. The tendency of As uptake and removal rate in Pteris vittata were consistent with the change of its biomass, showing an increasing and then decreasing trend. When treated with GST6, the uptake and removal rate of As of Pteris vittata reached the maximum values, 1795.10 μg·plant^-1 and 0.59%, respectively, which were 1.85 and 1.90 times those of CK. The comprehensive results indicated that the best remediation effect of Pteris vittata was obtained when the proportion of complex plant derived activator was GST6 (6:12:2), which could be used as a new phytoremediation strategy for As contaminated soil.
