Levels of dissolved ammonia, nitrite, nitrate, phosphate and silicate, as well as chlorosity, dissolved oxygen and hydrogen sulphide in the water of Lake Mariut. Lake Mariut has suffered over the years from the untreated sewage, after the enforcement of the Egyptian Law for Environmental Protection (Law 4/). Egypt. J. Soil Sci. 56, No. 2, pp. (). W.

High BOD levels indicate lower in maruit oxygen DObecause the oxygen that is available in the water is being consumed by the bacteria leading to the inability of fish and other aquatic organisms to survive in the water bodies [ 1213 ]. The lake shore is home to fisheries and saltworks.
However, they have not changed in fish flesh. As far back as the early s, it was documented that salt was being refined from the western part of the lake. Biographical, Historical, and Mythological: Zn and Cd contents in water samples have decreased compared with former studies.
Water is the most valuable and vital resource for sustenance of life. Sampling of water and algae were carried out at four different sites throughout the period from July to Sept mafiut Tur J Fish Aqu Sci 3: The fish species Nile perch lives in the lake although its principal habitat is fresh water, and the lake contains some salt.
This page dgypt last edited on 12 Decemberat Thus, aquatic diversity is now in threatened condition.
Lake Mariout Basin, Egypt
Most of this water comes from reservoirs, rivers, streams and lakes; and these sources are vulnerable to pollution [ 1 ]. The study included some recommendations aiming at improving both water quality and ecosystem of the lake. Trace metals; Lake Mariut; Bioaccumulation; Cladophora herpestica.
Table 1 shows the parameters of water quality in the lake. Two bishops are historically documented:. There was a bishopric of Mareotes, in the Roman province of Aegyptus Primuswhich was a suffragan of the Metropolitan Archbishop of the Patriarchate of Alexandria.
Lake Abu Qir ceased to exist, and Lake Mariiut became brackish instead of fresh. Although it is not egypy human or aquatic health concern; but it can serve as an indicator of other water quality parameters.
Route, Navigation, and Landscape in Islamic Egypt. Jan 13, Abstract The present study was carried out to evaluate the concentrations egupt some trace metals in the water of Lake Mariut and their accumulation in tissues of the green alga Cladophora herpestica.
Pollution at Lake Mariut|INIS
Pb content in both fish flesh and water samples has shown a great decrease compared to previous studies. In other projects Wikimedia Commons. A four part snail: This was reflected in higher concentrations of these metals in algal tissues collected from these two sites.
The present study was carried out to evaluate the concentrations of some trace metals in the water of Lake Mariut and their accumulation in tissues of the green alga Cladophora herpestica. The concentrations of the selected trace metals were ranged between Pol J Environ Stud The permissible limits of BOD 0.
We suggest composting, especially for sludge and amriut as an alternative waste management scenario; especially the algal biomass is recommended on the basis of the analyzed and acceptable toxic metal content for compost processing.
Retrieved 24 November The results showed that mercury was totally undetected in fish and water samples. The Cd and Pb mean maiut in fish flesh of the present study 0. There are ancient tombs located on the shores of the lake.
Ruins of an ancient temple and an ancient replica of the Lighthouse of Mafiut are to be seen there. The Southern site 3 is located near the industrial zone and most of by sewage and other laie are discharged there.
At least years ago, the lake was fresh water, and much of it would dry up during the period just before the Nile flooded again. The magnitude of Cr, Cd and Pb metal bioaccumulation was found to be higherand times, respectively in samples collected from northern site site 1 when compared with metals collected from algal tissues from different sites Table 3.
When the British opened the lake to the sea in Napleon’s time it caused a salt-water flood that destroyed villages.
