Evaluation of Potential Health Risk, Heavy Metal Pollution Indices and Water Quality of Edku Lagoon- Egypt

Abstract

Contamination of aquatic environment by heavy metals (HMs) is a critical concern due to their potential toxicity and accumulation in aquatic habitats (Jordan et al., 2014; Tscheikner-Gratl et al., 2019). Under certain environmental conditions, HMs could accumulate to a toxic concentration level and then cause significant ecological impacts and problems for human health (Jaishankar et al., 2014; Wongsasuluk et al.,

Assessment of some heavy metals contamination and thier pollution indices in water and fish organs of (Oreochromis niloticus and Clarias gariepinus) in Burullus and Edku lakes, (A comparative study)

“…The above results revealed that concentrations of the investigated heavy metals in the two Lakes significantly increase at sites nearest to the drains due to the highly content of these metals in these drains. Similar finding obtained by many researchers (Koussa, 2000;Moussa, 2004;Saeed and Shaker, 2008;Farouk, 2009;Darwish, 2016;El Morshedy, 2017;El-Batrawy et al, 2018;Shetaia et al, 2020).…”

“…Barseek Drain transports mainly agricultural drainage water to the lake (Okbah and El-Gohary, 2002; Badr and Hussein 2010). These drains responsible for increasing the contamination in the Lake and Increasing contamination associated with increasing levels of heavy metals which adversely affected the fishery (Shetaia et al, 2020).…”

Effects of COVID-19 lockdown and unlock on health of Bhutan-India-Bangladesh trans-boundary rivers

“…As per Wilcox and USSL diagram, all the stations denote ‘excellent to good’ category for irrigation suitability of water with ‘high to medium’ permeable soil category in three phases. An important ecological factor salinity has a significant role inthe survival of organisms ( Shetaia et al, 2020 ). However, Potential Salinity is more dynamic in nature near coastal areas than inland water ( Shil et al, 2019 ).…”

Estimation of tilapia fish quality in Lake Edku through physiological analyses regarding trace element accumulation, antioxidant enzymes, proximate composition, and human health risk assessment as the ultimate consumer

“…Many fish species are collected from Edku Lake. These fish species included tilapia species (Farouk et al 2020;Shetaia et al, 2020). Tilapia species such as Oreochromis niloticus, Tilapia zillii, Sarotherodon galilaeus, and Oreochromis aureus, were ranked first followed by Clarias gariepinus in the total fish production of the Egyptian Lakes (Zahran et al 2015;Helal et al 2020).…”
