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.

It had no mouth connecting it to the Mediterranean, being fed with Nile water via a number of canals.
Biographical, Historical, and Mythological: Moreover, the study indicated that the high concentrations of trace metals in algal tissues demonstrated the utility of using Cladophora herpestica as a biomonitor of heavy metal contamination and bioavailability. Bagster and Sons, The high bioaccumulation abilities of Cladophora algae for selected metals have been confirmed. The Cd and Pb mean values in fish flesh of the present study 0.
There are kake tombs located on the shores of the lake. When the British opened the lake to the sea in Napleon’s time it caused a salt-water flood that destroyed villages.
Pollution at Lake Mariut|INIS
Although it is not a human or aquatic health concern; but it can serve as an indicator of other water quality parameters. Algae are known to be good indicators of the extent of pollution in aquatic Ecosystems [ 34 ]. 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. This was reflected in higher concentrations of these metals in algal tissues collected from these two sites. The concentrations of trace metals exceeded the Egyptian Standards limits.
As far back as the early s, it was documented that salt was being refined from the western part of the lake. Although technically a Latin titular bishopric, it has had mqriut Eastern Catholic incumbents, notably those of Egypt’s native Coptic Catholic Church sui iuris Alexandrian Rite.

Cladophora herpestica abundantly growing on the surface of the Mariut Lake accumulates heavy metals from the aquatic environments. Rapid urbanization and industrialization have negative implications for water quality, where the industrial effluents directly discharge into the rivers without any consideration of the environment [ 2 ].
Retrieved 24 November These variations in bioaccumulation factors may be due to dilution of the lake towards the north [ 4 – 6 ]. Archived from the original on 24 November British Victory in Egypt: Int J Fish Aqu Sci 1: Algae Cladophora herpestica were collected in plastic bags containing seawater and transported immediately to the laboratory for analysis [ 3 ].
The Southern site 3 is located near the industrial zone and most of by sewage and other inputs are discharged there.
The levels of Fe obtained were very low compared to previous studies. This incineration causes air pollution and worsens the quality of the Ecosystem. Wikimedia Commons has media related to Lake Mariout.
Sampling of water and algae were carried out at four different sites throughout the period from July to Sept All chemicals used were of analytical reagent grade [ 4 ].
Settlements Alexandria Lake Mariout Arabic: Lake Abu Qir ceased to exist, and Lake Mariout became brackish instead of fresh. The current waste management in Egypt is based on independent, self- solid waste incineration, including combustion of the bankdischarged algae [ 2 ]. The water of the collected samples was mostly alkaline 7. Table 2 shows the concentrations of trace metals in water samples and algal tissues collected from the different sampling sites in the lake. A six point calibration procedure was applied with multi-element calibration solution Merck ICP multi-element standard solution IV [ 11 ].
It has had the following incumbents, so far of ebypt fitting episcopal lowest rank: The End of Napoleon’s Conquest. A map showing the sampling site from Lake Mariut.
