The ability of indoor plants to purify benzene pollution is the basic basis for the selection of plants for ecological remediation of indoor benzene pollution. In this study, the purification rate and the purification amount per unit leaf area of 13 test plants at three benzene concentrations were determined by indoor fumigation experiments, and the benzene absorption and purification abilityability of indoor plants were comprehensively evaluated. The results showed that (1) there was a significant correlation between benzene concentration and purification rate and purification amount per unit leaf area. (2) At the three concentrations, Spathiphyllum floribundum showed the highest purification rate and Sansevieria trifasciata var. laurentii showed the highest purification per unit leaf area. (3) The combined results showed that Sansevieria trifasciata var. laurentii, Spathiphyllum floribundum and Aloe arborescens were the strongest absorbers and purifiers, while Podocarpus nagi and Anthurium andraeanum 'Pink champin' had the weakest absorption and purification capacity. The results of this study provide a theoretical basis and reference for the selection of plants with strong capacities to adsorb and purify benzene pollution in indoor air.
室内植物净化苯污染的能力是选择用于室内苯污染生态修复的植物的基本依据。本研究通过室内熏气实验，测定了 13 种测试植物在三种苯浓度下的净化率和单位叶面积的净化量，综合评价了室内植物对苯的吸收和净化能力。结果表明：（1）苯浓度与净化率和单位叶面积净化量之间存在显著相关性。（2）在三种浓度下，蔓绿绒表现出最高的净化率，而绿宝石虎皮兰表现出最高的单位叶面积净化量。（3）综合结果表明，绿宝石虎皮兰、蔓绿绒和芦荟是最强的吸收和净化剂，而罗汉松和安祖花‘粉红冠军’的吸收和净化能力最弱。本研究结果为选择具有较强吸收和净化室内空气中苯污染能力的植物提供了理论依据和参考。
