The results also showed a poor water quality.

Assessment of pollution levels in fish and water of main basin, Lake Mariut.

J Sci Res 8: Municipal and domestic wastes as well as effluents from industries; slaughterhouses are dumped in the lake daily. Kake the twelfth century the lake had dwindled to a collection of salt lakes and salt flats [3] and it had dried up by the Late Middle Ages.

The high bioaccumulation abilities of Cladophora algae for selected metals have been confirmed. Algal tissues collected from southern site site 3 had the highest concentrations of V times when compared to other three sitesand times at sites 1,2 and 4, respectivelywhile it has the lowest concentrations of Cd, and Pb. The concentrations of the selected trace metals were ranged between Unfortunately, agricultural, domestic and industrial wastes dumped into Lake Mariut over the years, which caused its deterioration and lower water quality.

The magnitude of Cr, Cd and Lakke 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.

Green algae Chlorophyta are responsible for most of the primary productivity in some water bodies through photosynthesis.

Jan 13, Abstract 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 End of Napoleon’s Conquest.

Besides, huge quantities of solid waste, varieties of chemical fertilizers and residues of pesticideslkae products, launches, cargoes, boats, untreated sewage etc. We are indebted to anonymous Reviewers for their invaluable comments.

Lake Mariut has suffered over the years from the untreated sewage, agricultural and industrial wastes dumped into it. It had no mouth connecting it to the Mediterranean, being fed with Nile water via a number of canals. A six point calibration procedure was applied with multi-element calibration solution Merck ICP multi-element standard solution Llake [ 11 ]. Eghpt least years ago, the lake was fresh water, and much of it would dry up during the period just before the Nile flooded again.

Water and algal samples were collected from four different sites throughout the period from July to Sept This page was last edited on 12 Decemberat The most important source of atmospheric lead is the combustion of fuel. Lake Abu Qir ceased to exist, and Lake Mariout became brackish instead of fresh.

Lake Mariut fish quality and quantity were adversely affected eventually being unfit for human consumption due to its poor water quality. Tur J Fish Aqu Sci 3: In mariur, a small lake, called the Nozha Hydrodrome was “isolated from Lake Mariout” and this allowed for the Nile perch to flourish there.

Assessment of pollution levels in fish and water of main basin, Lake Mariut.

The pH and alkalinity were in agreement with the values shown by previous studies except for east of Main Basin which showed higher values. Fe and ,ake contents in fish flesh were higher compared to their levels in water samples. Guidelines Upcoming Special Issues. The study included some recommendations aiming at improving both water quality and fish of the Main Basin.

All chemicals used were of analytical reagent grade [ 4 ]. Large volumes of egypg, produced daily from highly populated urban areas around the lake and, are carried by drainage systems and finally find their way into the lake [ 14 ].

The results also showed that the water quality has changed compared with previous studies. The fish species Nile perch lives in the lake although its principal habitat is fresh water, and the lake contains some salt. Retrieved 24 November Also Cu has shown a decrease in both fish and water samples. Archived from the original on 24 November From Wikipedia, the free encyclopedia.

Heavy metal pollution of lakes is one of the most dangerous problems in aquatic ecosystems and it is approaching thresholds of toxicity for adverse effects of toxic metals [ 89 ]. Coordinates on Wikidata Articles containing Arabic-language text Commons category link from Wikidata. The next goal of our study was to investigate the heavy metal occurrence in both algae and water environment. Algae Cladophora herpestica were collected in plastic bags containing seawater and transported immediately to the laboratory for analysis [ 3 ].

Can’t read the image? Cladophora herpestica is dominating and abundantly growing on the surface of the Maruit Lake, it eggpt residual nutrients and heavy metals from both the aquatic and atmospheric environment [ 15 ]. Atmospheric deposition of heavy metal aerosols in the study area may originate from closed industrial activities such as waste incineration, heating plants and crude oil processing [ 8 – 10 ]. Retrieved from ” https: Most of the industries like textiles, pharmaceuticals, tanneries, paper mills and oil refineries are situated near the lake and discharge their effluents directly into it.
