| Abstract | ||||
| The present study provides quantitative assessment of the hydrosoil and overlying water characteristics in addition to vegetation analysis of five aquatic habitats and their wet shorelines dominated by Ceratophyllum demersum, Myriophyllum spicatum, Potamogton crispus, P. nodosus and P. pectinatus. Experimental study was conducted to evaluate rate of release of heavy metals from living and dead hydrophytes to the surrounding water. The bottom sediments and overlying water were different markedly in the five habitats. The sediments samples were sandy textured with predominance of fine sanarticles size=0.211 – 0.104 mm), whereas sites and clay fractions constitute small proportion. Organic carbon, total soluble salts, anions and cations were generally higher in summer months. The floristic components of the five communities comprised 51 species related to 27 families. Poaceae, Asteraceae, Cyeprceae, and Potomogetonaceae were the major families contributing 45% of the recorded species. Therophytes were the common life – froms. Rate of heavy metals release from living plant samples was higher than that from the dead samples. | ||||
