“…Burullus Lake environment, the secondlargest coastal lagoon in Egypt, has deteriorated as a result of its strategic location within the Nile Delta, where the lake receives the majority of the Nile Delta region's drainage water through several agricultural drains. The drainage water is primarily nutrient-rich freshwater contaminated by heavy metals and agricultural fertilizer (Hany et al 2022;Sheta, 2019). Burullus Lake is rich in phytoplankton and organic matter, whereas the lake is categorized as a hypereutrophic water body with poor and declining water quality based on the trophic state index (Elsayed et al 2019).…”

L ake Burullus is the second largest one that is located in the Nile Delta and is connected to the Mediterranean by a narrow outlet. This Lake faces various anthropogenic-induced implications that threat its ecosystem and biodiversity. The prime objective of this study is investigating the impacts of climate change and seasonal variation on water quality and Nile Tilapia fish (Oreochromis niloticus) of Lake Burullus, during 2022. Five stations: (1) El-Burullus drain; (2) Bougaz El-Burullus; (3) Drain ( 7); (4) El-Shakhloba and (5) Mastrou were studied. Surface water samples were collected for assessment water quality from these stations during Four seasons. Also, fish serum and muscles samples were collected for biochemical parameters. Results showed the physicochemical criteria of water quality were attributed with seasonal variation. Salinity % of Lake water was the highest during Winter and Spring seasons especially at Bougaz El-Burullus. Dissolved oxygen (DO) and ammonia (NH3) were significantly increased during Summer and Autumn. The study showed seasonal changes in the level of total protein, albumin, globulin, AST, ALT in serum of Tilapia fish. These biochemical markers were significantly increased during summer. Besides, Muscles total protein, total lipids and glycogen content were significantly decreased during Summer comparing with other seasons.In conclusion, Lake Burullus water quality, serum biochemical markers and muscles content of Nile Tilapia fish are affected by climatic changes during seasonal variation and environmental stress particularly at the discharge points which must be monitored and controlled.

“…Due to its importance, it has been declared a protectorate and has been registered as a RAMSAR site (a wetland site selected to be of international importance under the RAMSAR Convention) [30]. Additionally, the lake has been recognized as an Important Bird Area by Birdlife International [31,32].…”

This paper proposes a pragmatic approach for rapid assessment of the weighted contribution of the main waste streams contributing to pollution of surface water bodies. A case study was conducted on Lake Burullus in Egypt. The lake suffers from pollution due to many human-based activities around the lake, such as domestic, industrial, agriculture, fish farming, and solid wastes. The weighted contribution of these activities was assessed in terms of chemical oxygen demand (COD), total nitrogen (TN), and total phosphorus (TP). The results showed that the highest organic load is due to the domestic wastewater pollution component (63.2% of COD load), followed by fish aquaculture (35.4%). The highest TN (43.9%) and TP (58.3%) pollutant loads to Lake Burullus are due to the agricultural pollution component, followed by fish aquaculture with pollutant loads of 28.5% and 25.3%, respectively. The industrial wastewater pollution component has a very small effect on the pollution of Lake Burullus. The assessment of this study will help identify and magnify the key polluters and thus guide the decision-makers to prioritize investment planning for depollution intervention projects. For example, if the target is to reduce COD loads, investments must be directed toward the rehabilitation and expansion of wastewater treatment plants (WWTPs).

Burullus Lake, which is the second-largest coastal lagoon in Egypt, is deteriorating due to nutrient enrichment and pollutant loading. The study aims to assess the lake’s water quality using water quality indices and microbiological assessment. Surface water samples were collected from Burullus Lake in winter and summer, as well as samples from drains that discharge waste into the lake. Most lake stations are classified in the marginal category based on the water quality index (WQI). Dissolved oxygen, ammonia, copper, and cadmium have the greatest impact on WQI, reflecting pollution loads. Based on the contamination index, heavy metal classification results ranged from “lowly polluted” to “highly polluted.” According to the Nemerow Index, human activity has significantly impaired the ecology of the lake and surrounding drains through copper and cadmium pollution. The fecal coliform/fecal streptococci ratio was less than 0.6 in lake water samples, suggesting fecal contamination from domesticated animal wastes. Drain water contaminated with fecal streptococci indicated frequent contamination. Several drains allow a significant amount of effluent, including high amounts of pesticides and fertilizers, to enter the lake, causing serious metal and microbiological pollution Dredging and deepening the inlet link between the lake and Mediterranean Sea have had a positive impact on water quality. However, there are still other options for improving the lake’s health. Therefore, it is recommended to routinely check Burullus Lake’s water quality and its surrounding drains to keep track of its condition and assess any improvement efforts’ effectiveness.
