Trace metals (TMs) that accumulated in different crops irrigated with untreated wastewater are public hazard problem. The present work aimed to evaluate the impact of utilizing untreated agricultural water in the irrigation system of the peas crop ( Pisum sativum L.) until seed production on soil and plant characteristics. It also aimed to assess the effect of the applied wastewater on nutrients and TM contents in both soil and different plant parts (root, shoot ,and seed), and it extended to study TMs’ bioaccumulation and translocation ability of pea plant. Three composite soil and water samples were collected from the agricultural field (30°32’N and 31° 0′E) and agricultural wastewater effluent (30°34.5’N and 31°00.42′E) in Shebin El-Kom city used in irrigation of different crops. A pot experiment (each pot of 15 × 20 cm) was carried out in the botanic garden of Faculty of Science, Menoufia University, Egypt. TMs and nutrients were investigated for soil and plant samples. There was a significant increase in trace metal contents: cadmium (Cd), copper (Cu), chromium (Cr), iron (Fe), manganese (Mn), nickel (Ni), lead (Pb), and zinc (Zn) for soil and pea plants as a result of irrigation with wastewater. Also, it caused a significant decrease in soil nitrogen (N), phosphorous (P), and Potassium (K) and plant (N, P, K, carbohydrates, and proteins) nutrients. A significant decline in pea growth parameters and the content of chlorophyll a and b and carotenoid in pea leaves were recorded. A high significant in TMs content for seeds (edible parts) was recorded (Cd = 75.6, Cu = 9.7, Cr = 29.8, Fe = 1123.6, Mn = 82.2, Ni = 26.8, Pb = 131.4 and Zn = 35.7 mg kg −1 ). The concentration of Cd, Cr, Fe, and Pb in seeds was in the phytotoxic range. Irrigation with wastewater shows a negative impact on the soil and plant characteristics. Also, it causes a significant decline in soil and plant nutrients. At the same time, it increases the concentration of TMs for soil and all plant organs. The concentration of Cd, Cr, Fe and Pb reached to the phytotoxic range in its seeds. Authors recommended that pea cultivated in soil and/or irrigated with untreated wastewater was not safe for human and animal consumption.

作为废水灌溉的结果，豌豆植物 (Pisum sativum L.) 中积累的痕量金属

用未经处理的废水灌溉的不同作物中积累的痕量金属 (TM) 是公共危害问题。目前的工作旨在评估在豌豆作物 (Pisum sativum L.) 的灌溉系统中使用未经处理的农业用水直至种子生产对土壤和植物特性的影响。它还旨在评估应用废水对土壤和植物不同部位（根、芽和种子）中养分和 TM 含量的影响，并将其扩展到研究 TM 对豌豆植物的生物积累和易位能力。从 Shebin El-Kom 市的农田（30°32'N 和 31°0'E）和农业废水流出物（30°34.5'N 和 31°00.42'E）收集了三个复合土壤和水样品，用于不同作物的灌溉。在埃及梅诺菲亚大学理学院植物园进行盆栽实验（每盆 15 × 20 cm）。研究了土壤和植物样品的 TM 和养分。微量金属含量显着增加：镉（Cd）、铜（Cu）、铬（Cr）、铁（Fe）、锰（Mn）、镍（Ni）、铅（Pb）和锌（Zn）由于废水灌溉而产生的土壤和豌豆植物。此外，它还导致土壤氮 (N)、磷 (P) 和钾 (K) 以及植物（N、P、K、碳水化合物和蛋白质）养分显着减少。豌豆生长参数和豌豆叶中叶绿素 a 和 b 以及类胡萝卜素的含量显着下降。记录到种子（可食用部分）的 TMs 含量很高（Cd = 75.6，Cu = 9.7，Cr = 29.8，Fe = 1123.6，Mn = 82.2，Ni = 26.8，Pb = 131.4 和 Zn = 35.7 mg kg -1 ）。种子中Cd、Cr、Fe和Pb的浓度在植物毒性范围内。用废水灌溉对土壤和植物特性有负面影响。此外，它还会导致土壤和植物养分显着下降。同时，它增加了土壤和所有植物器官的 TM 浓度。其种子中Cd、Cr、Fe和Pb的浓度达到了植物毒性范围。作者建议在土壤中种植和/或用未经处理的废水灌溉的豌豆对人类和动物食用是不安全的。同时，它增加了土壤和所有植物器官的 TM 浓度。其种子中Cd、Cr、Fe和Pb的浓度达到植物毒性范围。作者建议在土壤中种植和/或用未经处理的废水灌溉的豌豆对人类和动物食用是不安全的。同时，它增加了土壤和所有植物器官的 TM 浓度。其种子中Cd、Cr、Fe和Pb的浓度达到植物毒性范围。作者建议在土壤中种植和/或用未经处理的废水灌溉的豌豆对人类和动物食用是不安全的。
