Abstract

Background

An improper disposal of hazardous medical waste in soil cause severe soil pollution and is becoming challenging to handle by eco-friendly way. Fortunately, the selective plant based treatment on medical waste polluted soil can be a feasible approach. Thus, the metal removal competence of Jatropha integerrima was analyzed in this research on medical waste polluted soil.

Methods

The soil characteristics like pH, Ag, As, Cd, Cr, Hg, Pb, Zn, and Mg were analyzed by typical digital pH meter and acid digestion method. The greenhouse experiment was performed with J. integerrima on test soil sample. The plant pigments and peroxidises (POD) activity was recorded in these study respective standard methods.

Significant findings

Soil has alkaline pH and tested heavy metal contents were beyond the permissible limits. The J. integerrima based phytoremediation study revealed that the soil alkaline pH was considerably minimized as close to neutral. Metal quantities such as Ag: 3.0 ± 0.11, As: 4.46 ± 0.21, Cd: 38.41 ± 1.65, Cr: 36.02 ± 1.3, Hg: 3.25 ± 0.14, Pb: 38.34 ± 1.32, Zn: 45.91 ± 2.28, and Mg: 29.02 ± 1.52 mg Kg⁻¹ were reduced from 100 m soil and they accumulated in plant biomass. The real-field experiment will be performed to assess this plant potential and it will be the future perspective of this study.

在温室条件下用麻风树处理受有害医疗废物污染的土壤的可持续方法

危险医疗废物在土壤中的不当处置造成了严重的土壤污染，以生态友好的方式处理是一个挑战。幸运的是，植物选择性处理医疗废弃物污染土壤是一种可行的方法。因此，本研究分析了麻疯树对医疗废弃物污染土壤的金属去除能力。方法采用典型的数字pH仪和酸消化法分析土壤pH、Ag、As、Cd、Cr、Hg、Pb、Zn、Mg等特征。在大棚试验中，在试验土样上进行了灌浆试验。分别用标准方法测定植物色素和过氧化物（POD）活性。重要发现土壤pH值呈碱性，重金属含量超标。植物修复研究表明，土壤碱性pH值显著降低，接近中性。100 m土壤中重金属含量Ag: 3.0±0.11,as: 4.46±0.21,Cd: 38.41±1.65,Cr: 36.02±1.3,Hg: 3.25±0.14,Pb: 38.34±1.32,Zn: 45.91±2.28,Mg: 29.02±1.52 Mg Kg - 1。实地试验将对该植物的潜力进行评估，这将是本研究的未来前景。
