Abstract
The present study was carried out on some plants of the junction canal (El-Qabouty) in Lake Manzala to investigate the state of water quality in the canal, which receives wastewater from the industrial and investment zones of Port Said with different industry of chemicals, paints, dyes, textiles and others. Also, the study aims to estimate the efficacy of Phragmites australis and Typha domingensis in heavy metals phytoremediation. The discharge of such untreated or partially treated industrial wastewater may affect the water quality, hydrosoil properties and macrophytic vegetation along the shores and banks of El-Qabouty Canal. The macrophyte Phragmites australis and Typha domingensis are the major component of reed stands along the shores of Lakes and wetlands in Egypt. They grow on soils with different pH, salinity, fertility, and texture. The network of their emergent stems emerge from a belowground network of rhizomes that play a role in clonal spread of the plant.
Two selected sites were chosen to represent spatially different degrees of pollution from the discharged outlet of the industrial area along the EL Qabouty junction canal. The first site was about 4 km far away from the outlet pipe at the Northern Site of El- Qabouty canal (NSQ), while the second one was nearby the discharge outlet Southern Site of El- Qabouty canal (SSQ).
The present study clearly shows that SSQ site near to the industrial drain output in Qabuoty canal is more polluted than NSQ that is relatively far from the source of industrial output that proves the industrial wastewater that flows into the canal is untreated, as the factories are called. There are seasonal differences in the physical and chemical properties of water and hydrosoil between the two studied sites. Chlorine was present in large quantities in water and hydrosoil which could be attribute to the presence of the Sinmar Chemicals Factory, where chlorine is the main product in its manufacture.
