We investigated the phytoremediation potential ofSenna occidentalisL., a pantropical plant that has been associated with tolerance to heavy metal-contaminated soils around mining sites. Seedlings ofS. occidentaliswere exposed to cadmium chloride (CdCl2) and sodium arsenate (Na3AsO4) at concentrations of 200, 300, and 400 mg L-1under greenhouse conditions. Heavy metal tolerance was assessed by comparing biomass and stress indicators such as chlorophyll, proline, and hydrogen peroxide content. Arsenic treatment had more toxic effects than cadmium onSennaphysiology. Regardless of concentration of arsenic applied, the biomass decreased by 50% as compared to control and cadmium-treated plants. Chlorophyll content decreased with exposure to both heavy metals. Higher concentration of Cd and As (400 mg L-1) resulted in 50% reduction in chlorophyll content. Proline and hydrogen peroxide levels were higher in arsenic-treated plants compared to controls and cadmium-treated plants, indicating an enhanced stress response when exposed to arsenic. When heavy metal content was measured, there was a significant accumulation of arsenic in the leaves, stems, and roots, indicating that arsenic in these tissues was responsible for the profound changes in biomass, proline, and hydrogen peroxide content. In contrast, although significant, there was less cadmium uptake bySennaand tolerance can be seen, which was reflected by normal biomass, proline, and hydrogen peroxide levels. High translocation of metals from soil into roots and low translocation from root to shoot tissues suggests the potential forS. occidentalisto be used for phytostabilization of arsenic- and cadmium-contaminated soils.

“…Bioaccumulation coefficient (BAF) was calculated as reported by (Chandra and Hoduck, 2018) and as in the following equation: BAC = HM Shoot / HM soil Where, HM shoot = concentration of heavy metals in Stem and Leaves, HM soil= Concentration of heavy metals in Soil. Bioconcentration Factor (BCF) was calculated as reported by (Chandra and Hoduck, 2018) in the following equation: BCF = HM Root / HM soil Where HM Root = the concentration of heavy metals in the roots. HM soil = the concentration of heavy metals in the soil.…”

إن الهدف من هذه الدراسة هو تقييم التحمل والكفاءة شتلات السبحبح (Melia azedarach L.) في استخلاص الكادميوم (Cd) والرصاص (Pb) من التربة الملوثة ، مع معرفة سلوكها في امتصاص وتراكم هذه المعادن في أجزاء المختلفة للنبات، بالاعتماد على بعض مقاييس تقنية المعالج النباتي (Phytoremediation) لتقييم مدى ملائمة هذه الشجرة في تقنية المعالجة النباتية. أجريت التجربة من بداية شهر اذار حتى نهاية شهر حزيران لعام 2022 باستخدام شتلات M. azedarach بعمر عام واحد والتي تم تربيتها في الاصص البلاستيكية تحتوي على 10 كغم خليط تربة جافة يتكون من (1 تربة طينية رملية: 1 تربة حقلية) والتي عوملت بتراكيز Cd (0، 25، 50، 75، 100) ملغم.كغم-1 تربة جافة على هيئة CdCl2.2,5 H2O، و تركيزات Pb (0، 200، 400، 600، 800) ملغم.كغم-1 تربة جافة على هيئة PbCl2، مع العلم أن تربة الكنترول تحتوي على 0.149 و 4.395 ملغم.كغم-1 تربة جافة منCd وPb ملغم.كغم-1 على التوالي، صممت التجربة حسب تصميم القطاعات العشوائية الكاملة. أظهرت النتائج أن التربة الملوثة بمستويات مختلفة من CdوPb كان لها تأثير بارز على معظم صفات المدروسة لشتلات M. azedarach وكذلك تراكم هذه المعادن في أجزاء المختلفة للنبات. تزداد هذه التأثيرات مع زيادة تركيز هذه المعادن الثقيلة في التربة. تأثير Pb على الكتلة الحيوية لمجموع الخضري و محتوى الكلي للكلوروفيل كان أكثر مقارنةً مع Cd، و أيضاً تأثرت الكتلة الحيوية للجذر بالكادميوم أكثر من الرصاص. كان المحتوى المتراكم لهذين المعدنين في نظام الجذري أكثر من نظام الخضري دون ترك أي أعراض سامة، مما يشير إلى أن هذه الشجرة تعتبر معالج نباتي مقاوم وملائم للتربة الملوثة بـ Cd و Pb.

A field experiment was conducted in the lath house of the Agricultural Research and Experiment Station of the College of Agriculture in the governorate of Kirkuk-Iraq for the period from 1/3/2022 to 1/9/2002, to evaluate the efficiency of N.Oleander L.Album Plenum in the phytoremediation of lead (Pb) contaminated soil by adding Humic acid with three levels (0,5,10) ml..pot−1 of soil directly, the design of the experiment used is R.C.B.D. The results of the mechanisms and indicators of the efficiency of the nerium oleander in the extraction of heavy metals showed that the oleander plant with the assistance of humic acid has a high ability to absorb and accumulate the lead element very effectively, and the concentration of 10 ml.pot−1 of humic increasing the concentration of the Pb in the shoot and root system (30.71, 16.83 PPM) respectively, however the concentration of lead in the control plants was (25.32 and 14.36 PPM) respectively. Translocation factor TF>1 for all humic concentrations (1.82, 1.88, 1.77), respectively, and this indicates the high ability of the oleander to absorb and accumulate heavy elements. The concentration of 10 ml.pot−1 of humic acid gave the highest value of the bioaccumulation factor (BAF) 0.85, however it was 0.64 in the control plant. The concentration of 10 ml.pot−1 of humic was also superior in giving the highest value of the concentration index (CI), which ranged 1.27, and 1.06 in the control plant.
