Phytoremediation is an environmentally friendly therapy to minimize soil pollution. Cypermethrin (CYP) is one of the most frequently used pyrethroid insecticides against a variety of pests. We aimed at evaluating the potential of using an economic plant like tomato (Solanum lycopersicum L.) as a control alone and together with Plantago major L. (PM) for the uptake of CYP residue from contaminated soil, also, investigating the antioxidant enzymes such as (SOD, POD, and CAT) in roots of PM and tomato. For the first time, we studied the intercropping between PM on tomato plants for the uptake of CYP residue from contaminated soil and phytoremediation of PM as a curative plant to save tomato plants from CYP residue. In a pot experiment, we have cultivated PM and tomato in soil polluted with CYP (10 μg g). Data showed that PM and tomato accumulated significant amounts of CYP in their tissues. However, PM is better than tomato in uptake CYP from the soil. The longest half-life value (t) of CYP was in PM + tomato together treatment (12.7 days), and the shortest was in the soil with tomato alone (6.81 days). Moreover, the activity of SOD, POD, and CAT in treated tomato and PM roots significantly (p > 0.05) exceeded control plants after 8 days from exposure. In this study, a good strategy was recommended to uptake CYP residue from soil by PM and protect tomato plants from CYP residue as well as safe for human and non-target organisms.
植物修复是一种环保疗法，可以最大限度地减少土壤污染。氯菊酯 (CYP) 是一种最常用于防治各种害虫的拟除虫菊酯类杀虫剂。我们旨在评估像番茄 (Solanum lycopersicum L.) 这样的经济作物单独使用和与车前草 (Plantago major L.) 一起使用来从受污染土壤中吸收 CYP 残留的潜力，同时研究 PM 和番茄根部的抗氧化酶，如 (SOD、POD 和 CAT)。我们首次研究了车前草与番茄间作对从受污染土壤中吸收 CYP 残留和车前草作为治疗植物修复 CYP 残留以保护番茄植物的作用。在盆栽实验中，我们在 CYP（10μg g）污染的土壤中种植了车前草和番茄。数据表明，PM 和番茄在其组织中积累了大量的 CYP。然而，PM 从土壤中吸收 CYP 的能力优于番茄。CYP 的最长半衰期 (t) 值出现在 PM+番茄共同处理中（12.7 天），最短的出现在单独种植番茄的土壤中（6.81 天）。此外，暴露 8 天后，处理过的番茄和 PM 根中的 SOD、POD 和 CAT 活性明显（p>0.05）超过对照植物。在这项研究中，推荐了一种从土壤中吸收 CYP 残留的良好策略，既能保护番茄植物免受 CYP 残留的侵害，又能保证人类和非目标生物的安全。
