The atrazine and clomazone molecules have potential to contaminate environments, especially water resources. Phytoremediation decontamination can prevent or reduce the quantity of these products reaching watercourses. The objective was to evaluate the remedial potential and the physiological sensitivity of (DC.) Sch. Bip and Benth to atrazine and clomazone in soils contaminated with 0.0, 0.5, 1.0 and 2.0 times the recommended commercial dose of these herbicides. The photosynthesis, CO consumed stomatal conductance and transpiration of and , in soils contaminated with atrazine and clomazone, were evaluated. The herbicide residues were detected by ultra-high performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS) 30 days after the last herbicide application. The photosynthesis rate and CO consumed by and were lower in soils contaminated by atrazine and clomazone. had lower stomatal conductance and transpiration in soil contaminated with clomazone. and reduced the residues of these herbicides. The atrazine and clomazone reduced the physiological variables of and . These plants can be used to recover areas with residues of these herbicides, acting as filters that will decrease the amount of herbicides that would reach the watercourses.
莠去津和氯甲草醚分子有可能污染环境，特别是水资源。植物修复去污可以防止或减少这些产品进入水道的数量。本研究的目的是评估 （DC.） Sch. Bip 和 Benth 在受莠去津和氯甲草醚推荐商业剂量 0.0、0.5、1.0 和 2.0 倍污染的土壤中的修复潜力和生理敏感性。评估了在受莠去津和氯甲草醚污染的土壤中， 和 的光合作用、CO 消耗的气孔导度和蒸腾作用。在最后一次施药 30 天后，用超高效液相色谱串联质谱法（UHPLC-MS/MS）检测除草剂残留。莠去津和氯甲草醚污染的土壤中 和 的光合作用和 CO 消耗速率降低。氯甲草醚污染的土壤中 的气孔导度和蒸腾作用降低。 和 降低了这些除草剂的残留。莠去津和氯甲草醚降低了 和 的生理变量。这些植物可用于回收含有这些除草剂残留物的区域，作为过滤器，减少进入水道的除草剂数量。
