The phytoremediation potential of Brazilian trees species Calophyllum brasiliense, Eremanthus crotonoides, Hymenaea courbaril, Inga striata, and Protium heptaphyllum was investigated for contaminated soils containing ametryn and hexazinone. Visual injury, chlorophyll content, plant height, leaf temperature, leaf number, and water-efficient use were evaluated. Residual herbicides at soil substrates were analyzed by LC/MS. Among the species C. brasiliense and H. courbaril were tolerant to both herbicides. P. Heptaphyllum presented tolerance at ametryn treatment. E. crotonoides, I. striata, and P. heptaphyllum died in hexazinone treatment. A high content of residual ametryn was found for E. crotonoides. In ametryn treatment, residual herbicide has decreased for C. brasiliense and E. crotonoides species. C. brasiliense highlighted among others becoming a good agent for phytoremediation of soils contaminated with traces of ametryn and hexazinone.
巴西树种巴西Calophyllum 树、Eremanthus crotonoides、 Hymenaea courbaril、Inga striata 和 Protium heptaphyllum 的植物修复潜力研究了含有莠去津和环嗪酮的污染土壤。评估了目视损伤、叶绿素含量、株高、叶片温度、叶片数和水分高效利用。通过 LC/MS 分析了土壤基质中的残留除草剂。在这些物种中，巴西 Calophyllum 和 Hymenaea courbaril 对两种除草剂都具有耐受性。P. Heptaphyllum 对莠去津处理具有耐受性。E. crotonoides、I. striata 和 P. heptaphyllum 在环嗪酮处理中死亡。E. crotonoides 中发现了高含量的莠去津残留。在莠去津处理中，C. brasiliense 和 E. crotonoides 物种中的残留除草剂有所减少。巴西 Calophyllum 等植物在植物修复受莠去津和环嗪酮污染的土壤方面表现出色。
