Abstract The findings of the present study showed that the concentrations of the investigated heavy metals in water, sediments and the studied aquatic plants of three types of hydrophytes: floating, submerged and emergent. The aim of the present work is to determine the phytoremediation, phytochemical, biochemical studies in addition to molecular studies using two molecular markers RAPD and ISSR of nine hydrophytes; including three species floating (Eichhornia crassipes (C. Mart.) Solms, Nymphaea lotus L. and Pistia stratiotes L.) and three species submerged (Ceratophyllum demersum L., Myriophyllum spicatum L. and Potamogeton pectinatus L.) and three species emergent (Echinochloa stagnina (Retz.) P. Beauv., Ludwigia stolonifera (Guill & Perr.) P.H. Raven and Persicaria salicifolia (Brouss. Ex Willd.) Assenov). Phytoremediation studies through estimations of five types of heavy metals in sediments, water and in plant tissues of these studied hydrophytes. The highest mean value of heavy metals in water was detected in water and sediments locations of emergent hydrophytes. The maximum value of heavy metals from nine locations was in Ammar drainage, Gamasa, Dakahlia, where the lowest value of heavy metals was observed in Kafr-Al-Tawila (Talkha), Dakahlia. |
