“…Meanwhile, Edku Lake gains input from diverse anthropogenic activities and Alexandria City wastewaters even though there is a minor intensity of industrial activities nearby (Mohamedein et al, 2018 ). Also, various sediment samples in Burullus Lake were devastated mainly by agricultural drainage water and little industrial and domestic waste discharges (El Baz, 2015 ).…”

The environmental pollution of lake systems due to anthropogenic factors is of growing concern worldwide. Manzala Lake is the largest northern coastal-deltaic lakes of Egypt and has socioeconomic impacts. In this study, the concentrations and origins of seven heavy metals (HMs) and the organic content in the Manzala Lake sediments were explored during the winter and summer. The concentration of the HMs and the organic content were quantified using inductively coupled plasma and loss-on-ignition techniques. Pearson’s correlation coefficient (PCC) and principal component analysis (PCA) were applied to evaluate the sources of the metals in the sediments. The HMs and organic matter were enriched during the winter season. The average concentrations of the HMs in the sediments conformed to the following sequence: Fe (14.13) > Mn (0.8) > Cu (0.11) > Zn (0.11) > Ni (0.06) > Pb (0.5) > Cd (0.002) (mg/kg). Sediment quality protocols showed that Mn, Cd, Cu, and Ni pose a significant threat to the aquatic environment in Manzala Lake. The geoaccumulation index (Igeo) values indicated pollution of the sediments with most metals, excluding Fe and Ni. The periodic mean Igeo pollution level followed the sequence Cd > Cu > Zn > Mn > Pb > Ni > Fe. The greatest pollution load index noted during the winter season was principally induced by Cd and Cu. The overall ecological risk index was moderate, with Cd being the most prominent HM. PCA combined with PCC showed that the HM enrichments in the southern (Bahr Al-Baqar Drain [S1], Bashteer [S3], Legan [S5], and Al-Ginka [S8]) and the extreme northeastern (El-Qapouti [S6]) parts of Manzala Lake sediments were mainly due to the discharge from different drains (industrial, agricultural, and municipal wastes) and the industrial region in Port Said, respectively. The lower HM concentrations from the extreme northern parts (Al-Boghaz [S2], Al-Temsah [S4], Al-Hamra [S7], and Al-Kowar [S9]) were due to their isolation from urban areas compared with the other localities. Extensive waste disposal was responsible for the HM pollution in the Manzala Lake sediments. Advanced treatment technologies and monitoring of the pollution in the water and sediments of Manzala Lake are required to decrease the accumulation of the heavy metals.

“…The lake is listed as a wetland site of international importance for migrating birds under the Ramsar Convention [36]. In recent decades, Lake Burullus has been subjected to severe human activities [27,35,37,38]. Permission to access Lake Burullus was granted by the Environmental Authority for the Burullus Protected Area, Egypt.…”

Loss of Coastal Wetlands in Lake Burullus, Egypt: A GIS and Remote-Sensing Study

Lake Burullus is the second largest lake at the northern edge of the Nile Delta, Egypt, and has been recognized as an internationally significant wetland that provides a habitat for migrating birds, fish, herpetofauna, and mammals. However, the lake is experiencing severe human impacts including drainage and conversion to agricultural lands and fish farms. The primary goal of this study was to use multispectral, moderate-spatial-resolution (30 m2) Landsat satellite imagery to assess marsh loss in Lake Burullus, Egypt, in the last 35 years (1985–2020). Iterative Self-Organizing Data Analyses (ISODATA) unsupervised techniques were applied to the Landsat 5 Thematic Mapper (TM) and Landsat 8 Operational Land Imager–Thermal Infrared Sensor (OLI–TIRS) satellite images for classification of the Lake Burullus area into four main land-use classes: water, marsh, unvegetated land surfaces (roads, paths, sand sheets and dunes), and agricultural lands and fish farms. The overall classification accuracy was estimated to be 96% and the Kappa index was 0.95. Our results indicated that there is a substantial loss (44.8% loss) in the marsh aerial coverage between 1985 and 2020. The drainage and conversion of wetlands into agricultural lands and/or fish farms is concentrated primarily in the western and southern part of the lake where the surface area of the agricultural lands and/or fish farms doubled (103.2% increase) between 2000 and 2020. We recommend that land-use-policy makers and environmental government agencies raise public awareness among the local communities of Lake Burullus of the economic and environmental consequences of the alarming loss of marshland, which will likely have adverse effects on water quality and cause a reduction in the invaluable wetland-ecosystem services.

“…In recent years, wastewaters are being directly released into the Lake via drains without treatment. Furthermore, the increase of petro-refineries and fertilizer industries are noted, representing sources of pollution (Ameen et al, 2013& El Baz, 2015. During winter NCPI was applied on the Lake stations to find that the highest scores (34, 32, 31 and 27) were calculated at stations 7 &11, 10 and 1 respectively indicating heavy polluted stations.…”

Lake Burullus is one of the most significant coastline lagoons in the Mediterranean basin. It is the second largest lake of the northern Egyptian lakes. It lies in the Nile Delta, between Longitude 30° 30-E and 31° 10-E and latitude 31° 21-N and 31° 35-N. The lake is separated from the Mediterranean Sea by a narrow sandbar. The area of Burullus Lake is about 420 km 2 of which 370 km 2 is open water (Younes, 2012). On the other side, the lake area was 588 km 2 in 1956 while it was 462 km 2 in 1974 and this reduction is owing to projects of reclamation along the eastern and southern sides of the lake and processes of fish farming (Younes, 2012). Lake Burullus is linked to the sea through the Burullus inlet (width 250 m and depth 5 m) at its northeastern edge. The lake is very shallow, with a depth ranged from 40 cm and 200 cm (El-Zeiny & El-Kafrawy, 2017). Eight drains (Burullus, El Gharbia, Nasser, Baltim, and drains 7, 8, 9, and 11) and only one canal (Brimbal Canal) discharge agricultural drainage water into the lake (El Baz, 2015). Domestic wastes, industrial and agricultural discharges have increased the pollutants in the lake. The increasing pollution of water resources in Lake Burullus makes the lake under severe ARTICLE INFO
