“…It is against this background that bio-indicators are preferred in environmental monitoring. Molluscs are effective biomonitors and have been widely used for heavy metal monitoring purposes worldwide (Obirikorang et al 2010, El-Sorogy and Attiah 2015, Abdel-Ghany 2017, Mohammad et al 2017, Heiba et al 2019, Usese et al 2019. They reflect traces of contamination better than finfishes because they are sediment dwelling and have pronounced ability to concentrate pollutants from sediments and water (McCaffrey et al 2017).…”

Concentration of mercury was investigated in the flesh and shell of two species of benthic mollusc, Crassostrea gasar and Tympanotonus fuscatus and in water and sediment from Makoko Creek, adjacent to the Lagos Lagoon between January to September 2019. Values obtained for physicochemical parameters in Makoko Creek (water temperature- 28.92±0.1°C; pH- 7.73±0.02; salinity- 14.23±0.05 ppt; dissolved oxygen- 5.34±0.02 mg/l; biological oxygen demand- 7.780±0.1 mg/l and chemical oxygen demand- 12.34±0.02 mg/l) were within the acceptable levels for survival, metabolism and physiology of aquatic organism. The concentration of mercury followed decreasing order as sediment >water >flesh >shell across locations for both species. For all the tested samples of C. gasar and T. fuscatus, biowater accumulation factor in flesh and shell were higher than those of bio-sediment accumulation factor. The coefficients of variance (CV %) in shells were lower than those of the flesh for both investigated mollusc species. It was shown that mercury contents of flesh or shells of C. gasar and T. fuscatu are directly affected by those of water and bottom sediment. J. Bio-Sci. 29(1): 143-151, 2021 (June)

Monitoring changes in accumulation of heavy metals in the Egyptian Delta region in 2010 and 2021, using the crayfish Procambarus clarkii (Girard, 1852) (Decapoda, Astacidea) as a bio-indicator

Accumulation of heavy metals in tissues of the crayfish Procambarus clarkii and in water were evaluated in areas located in the Egyptian Delta (Gharbiya, Kafr El-Shaikh, and Menofiya) in 2010 and 2021. Statistics showed that in 2010 the highest concentration of heavy metals in the digestive gland and in muscles was Zn, both in Gharbiya and Menofiya, while Fe was the highest accumulated in the digestive gland, and Pb was the highest in muscles of samples from Kafr El-Shaikh. The results showed that heavy metal loads decreased in Kafr El-Shaikh in 2021, whereas Fe increased significantly () in Gharbiya and Menofiya (41.44 ± 2.32, 47.25 ± 2.64 μg/g). Accumulation of Cd and Zn in gills and muscles decreased in all areas from 2010 to 2021, while a significant increase () was shown in Fe and Cu in 2021. All heavy metals significantly decreased () in waters of the studied areas from 2010 to 2021.
