摘要:以我国11种具有代表性的土壤为研究对象，通过外源添加Cr（Ⅵ）进行大麦根伸长毒性测试，以了解土壤理化性质对Cr（Ⅵ）的大麦毒性阈值包括半数效应抑制浓度（EC50）和10%效应抑制浓度（EC10）的影响。结果表明，土壤理化性质对Cr（Ⅵ）的植物毒性有显著影响，通过对数-对数剂量效应模型和刺激效应模型预测EC50值和EC10值，其变化范围分别为8.27～241.34 mg·kg-1和2.87～124.65 mg·kg-1，其最大值和最小值相差分别达到了29.2倍和43.4倍。相关分析结果表明，铁、铝氧化物含量、pH值和有机碳含量与Cr（Ⅵ）对大麦根伸长的毒性阈值相关关系显著（P<0.05），其中，铝氧化物含量和铁氧化物含量分别为控制EC50和EC10最重要的单一因子（R2=0.448、R2=0.429），其次为pH值和有机碳含量。基于相关性因子和Cr（Ⅵ）对大麦的毒性阈值建立了一元和多元线性回归方程，最优方程可以分别解释70.1%的EC50和60.4%的EC10变异，表明利用土壤理化性质建立的模型可以较好地预测土壤外源Cr（Ⅵ）对大麦的毒性阈值。

Abstract:The influence of soil physicochemical properties on toxicity threshold (EC x, x =10,50, the effective concentration causing 10% and 50% inhibition) of added Cr(Ⅵ) to barley root elongation was investigated in 11 representative Chinese soils. The results indicated that the phytotoxicity of Cr(Ⅵ) was affected by soil physicochemical properties significantly. The toxicity thresholds (EC50, EC10), which were calculated by log-logistic curve and Hormetic dose-response model, ranged from 8.27 to 241.34 mg·kg-1 and from 2.87 to 124.65 mg·kg-1, respectively, representing 29.2- and 43.4-fold variation among soils. The results of correlation analysis showed that iron oxide content, aluminum oxide content, pH value and organic carbon content were related to the toxicity threshold of Cr(Ⅵ) to barley root elongation significantly (P<0.05). Aluminum oxide content and iron oxide content were the most important predictors of toxicity thresholds (R2=0.448、 R2=0.429). The unary and multiple regression equations between soil properties and toxicity threshold were developed. When incorporating iron oxide content, aluminum oxide content, pH value and organic carbon content into regression models, 70.1% variance of EC50 and 60.4% variance of EC10 can be explained respectively, which indicated that the toxicity thresholds of added Cr(Ⅵ) can be well predicted by the models based on the main soil physicochemical properties.
