Root and shoot samples of Prosopis juliflora were assessed for their heavy metal content to evaluate the species as a green solution to decontaminate soils contaminated with lead and cadmium. The highest uptake of both the metals was observed in plants from industrial sites. Sites with more anthropogenic disturbance exhibited reduced chlorophyll levels, stunted growth, delayed and shortened reproductive phase. The ratios of lead and cadmium in leaves to lead and cadmium in soil were in the range of 0.62-1.46 and 0.55-1.71, respectively. Strong correlation between the degree of contamination and concentrations of lead and cadmium in plant samples identifies P. juliflora as an effective heavy metal remediator coupled with environmental stress.
对刺槐的根和茎叶样本进行了重金属含量评估,以评估该物种作为一种绿色解决方案,用于净化受到铅和镉污染的土壤。在来自工业场地的植物中观察到对这两种金属的最高吸收。受到更多人为干扰的场地表现出叶绿素水平降低、生长受阻、繁殖期延迟和缩短。叶片中铅和镉与土壤中铅和镉的比值分别在 0.62-1.46 和 0.55-1.71 范围内。污染程度与植物样本中铅和镉浓度之间的强相关性表明,刺槐是一种有效的重金属修复剂,同时还能缓解环境压力。
