This study seeks to assess the reaction of the eggplant (Solanum melongena L.) to soil samples contaminated. Following, cultivation, growth, and harvest, the plant samples were prepared and maximum absorption rates of heavy metals were measured in both leaf and fruit. The estimated daily intake (EDI), the target hazard quotient (THQ), and the bio-concentration factor (BCF) were measured at various intervals during the growth period of the plant. Spectral analysis was also performed to assess the reaction of target crops to heavy metals. The results showed that in the second and third stages of plant growth, the THQ values were more than 1 for infected plants with Cd, Pb, and Zn. According to results from the BCF analysis, the absorption rate in Pb, during the growth stages was relatively high, in crops contaminated by Ni was around 1 in the second and third stages, and in plants contaminated by Cd was extremely high. All crops contaminated by heavy metals showed higher reflection rates in the 400-500 and 600-700 nm range. So, using electromagnetic waves during different stages of growth, the reaction of eggplant cultivated in soil samples contaminated by heavy metals is predictable.
本研究旨在评估茄子（Solanum melongena L.）对受污染土壤样本的反应。随后，在种植、生长和收获后，对植物样本进行准备，并测量叶片和果实中重金属的最大吸收速率。在植物生长期间的不同时间间隔测量了估计每日摄入量（EDI）、目标危害系数（THQ）和生物浓缩系数（BCF）。还进行了光谱分析，以评估目标作物对重金属的反应。结果表明，在植物生长的第二和第三阶段，受 Cd、Pb 和 Zn 感染的植物的 THQ 值大于 1。根据 BCF 分析的结果，在生长阶段，Pb 的吸收速率相对较高，在受 Ni 污染的作物中，第二和第三阶段约为 1，而在受 Cd 污染的植物中则极高。所有受重金属污染的作物在 400-500nm 和 600-700nm 范围内的反射率均较高。因此，在不同的生长阶段使用电磁波，可以预测茄子在受重金属污染的土壤样本中的生长反应。
