It is recommended that there should be a reduction in the use of chemicals with high concentrations of heavy metals which is a significant source of pollution in the environment.ĪbouelFadi, K.Y., M.M.S. This suggests a dire need for intervention in controlling water pollution which is posed by anthropogenic activities in the state. It was revealed that the heavy metals concentration across the districts was higher when compared with recommended standards. The levels of Co, Cd and Pb which are disastrous to fish species were observed to be elevated while Zn and Cu were observed to accumulate in the fish tissues. After digestion of samples, Cadmium (Cd), Copper (Co), Chromium (Ch), Lead (Pb) and Zinc (Zn) were analyzed using Atomic Absorption Spectrometer (AAS). The water samples were collected using sterile bottles (2L) and labeled. Soil samples were collected using a soil auger, air-dried and stored in a sterile and well-labeled polythene bag. Fresh fish samples were collected and tissues from the dorsal area were used for analysis. Heavy metals were determined in samples of fish tissues, soil, and water from nine randomly selected fish farms based on production facility (earthen pond) in the Ekiti Central (EC), Ekiti North (EN) and Ekiti South (ES) senatorial districts of Ekiti state. ![]()
