| Abstract | ||
| The effect of water hyacinth "Eichhomia cerssipes" cultivation in earthen ponds on reducing the soluble heavy metals (Fe, Mn, Cu, Zn, B. Cd and Pb) contents in sewage waste water, soil surface and subsurface layer and in fish (tilapia, Oreochromis nitoticus) and (mullt, Mugit cephalus) was studied in an investigation for 150 days period. The investigation was carried out at Shader Azzam, Port Saied Govemorate. Results showed that, the average concentration of heavy metals in sewage wastewater significantly decreased with the increasing water hyacinth Cultivation in ponds. Also, the accumulations of heavy metals in soil layers were significantly decreased with increasing cultivation rate of water hyacinth cultivation. Cultivating water hyacinth in fish pond at 10 and15% resulted in higher reduction of heavy metals in water, soils layers and fish bodies with high production of fish. | ||
