Detection and effects of heavy metals in fish blood, water, sediment, food, and plants of different three farms in EL-Fayoum Governorate, Egypt

Abstract

The heavy metal contamination of Nile tilapia that were gathered from three fish farms is the focus of this investigation. This led to an  investigation of the chemical and physical characteristics of farm water. Heavy metals (Zn, Cd, Pb, Fe, and Cu) were also measured in fish  blood, water, sediment, food, and plants that were taken from the farms that were the subject of the investigation. The three farms, EL- Galini, EL-Locanda, and EL-Bats, had pH values of 7.95, 8.03, and 8.06, respectively, and dissolved oxygen values of 5.9, 7.2, and 6.0 (mg/l). In all three farms, the relative variation of heavy metal values in water was Fe>Zn>Cu>Pb>Cd. EL Galini farm had the highest result for  sediment among all the heavy metals studied, followed by EL-Bats farm and Locanda farm; however, fordiet locanda farm recorded  highest value for all the examined heavy metals followed by El-Bats then El Gilani farm.
