Heavy metals and nutritional composition of some naturally growing aquatic macrophytes of Northern Egyptian Lakes
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2015, Vol 6, Issue 3
Abstract
Aquatic plants are unchangeable biological filters and they carry out purification of the water bodies therefore, the determination of element compositions in these plants is essential for understanding their nutritive importance. Aquatic macrophytes are known as good indicators of heavy metal contamination in aquatic ecosystems and they act as biological filters by accumulating heavy metals from the surrounding environments. Under the present investigation, five aquatic macrophytes namely:- (Lemna gibba, Pistia stratiotes are floating plants),(Ceratophyllum demersum, Potamogeton pectinatus and Myriophylum spicatum are submerged plants) were collected from different locations at Nile delta lagoons (Burullus and Manzala) to investigate the bioindicative value of them by determining their contents of heavy metals and their nutritional composition. The results of the present study indicated that, levels of some metals such as zinc and copper are higher in almost all the species, in addition to Lemna gibba and potamogeton pectinatus showed the higher capacity of heavy metals accumulation than the other aquatic plants, Accordingly they could be used as reliable way for bio-monitoring of heavy metals and in sustainable development, management and pollution assessment in the northern deltaic lakes of Egypt.
