A COMPARATIVE STUDY ON THE EFFECTS OF LEAD AND ZEOLITE ON SERUM BIOCHEMISTRY OF CARP FISH, Cyprinus Carpio Linnaeus, 1758 (Cyprinidae)

One of the pollutants leading to heavy metal pollution is the lead element. The studies on exposure of fish to lead have shown that this exposure leads to negative effects on body weight, and digestive enzymes and lipase. In humans, the symptoms of chronic lead toxicity are renal malfunction, anemia, brain and liver damage, cancer, hyperactivity, and general psychological impairment. For struggling with this heavy metal contamination, we have a useful tool named Zeolite. Zeolites are used in many fields such as agriculture, metal industry, energy sector, manufacturing industry, water treatment, animal husbandry, struggling with environmental pollution, and etc. In this study, we utilized the biochemical parameters of carp fish (Cyprinus carpio) in order to reveal the effects of zeolite on fish health and production. The experiments were performed within 100 L glass aquariums with 85x40x30 dimensions. The study was planned for 3 different durations as 35 days, 90 days, and 120 days. The subjects were divided into 4 groups for each of experiment durations. The groups were named Pb(NO3)(2) group, Pb(NO3)(2) + Zeolite group, Zeolite group, and control group. At the end of each of the experiment period (on 35(th), 90(th), and 120(th) days), the fish in groups were weighed, and the average growth rates of each of the groups were calculated. The parameters used in blood analyses are glucose (GLU), blood urea nitrogen (BUN), total protein (TP), albumin (ALB), globulin (GLB), creatinine (CR), total bilirubin (TBIL), uric acid ([JA), and direct bilirubin (DBlL).
