A comparative study on the effects of lead and zeolite on serum biochemistry of carp fish, Cyprinus carpio Linnaeus, 1758 (Cyprinidae)
(2015-01-01) Mutlu E.; Demir T.; Kutlu B.
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 85×40×30 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(NC)3)2 group, Pb(NO3)2 + Zeolite group, Zeolite group, and control group. At the end of each of the experiment period (on 35th, 90th, and 120th 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 (UA), and direct bilirubin (DBIL).
Determination of environmentally relevant water quality parameters in Serefiye Dam-Turkey
(2016-01-01) Mutlu E.; Demir T.; Yanik T.; Sutan N.A.
The objectives of this study were to observe the monthly and annual changes in water samples through physicochemical methods, to determine the water quality properties, to investigate the pollution problems, to determine the suitability level in terms of aquatic life, and to classify the water quality in accordance with the SWQMR criteria. This study was carried out through monthly sampling between April 2011 and March 2014 in 3 stations at Serefiye Dam, which is a "Class B" dam according to the RAMSAR criteria. The samples were immediately taken to the laboratories for analyses. Station 1 is at the entrance point of Egridere into the dam, 2nd point is at western side of the dam (Serefiye town), and the Station 3 is located at the center of the dam. The water quality in Serefiye dam, which is under protection within the scope of RAMSAR convention, was determined to be Class II according to SWQMR. In order to protect the water quality and to ensure the sustainability of aquatic life in this dam, it is required to make regular observations and to monitor the parameters affecting the water quality and aquatic life.
Effect of zeolite and copper sulfate, administered alone and in combination on the biochemical components of blood serum of common carp, Cyprinus Carpio
(2016-01-01) Mutlu E.; Aydin S.; Demir T.; Yanik T.
Effects of zeolite have been described on the biochemical parameters of blood of Cyprinus carpio exposed to copper sulphate. The control fish showed 57.67% increase in body weight over a period of 90 days. This increase was 26.45% after exposure to copper sulphate (2mg/L) and 32.01% after Zeolite treatment (60 mg/L). When Zeolite was administered along with copper sulfate the fish showed 46.24% increase in body weight. Blood sampling were made for the determination of hematological values (glucose (GLU), blood urea nitrogen (BUN), total protein (TP), albumin (ALB), globulin (GLB), creatinine (CR), total bilirubin (TBIL), uric acid (UA), and direct bilirubin (DBIL)) at 30, 60, 90 days. Fish weight increased 26.45%, 46.29%, 32.01% and 57.67% respectively in groups and differences between groups were significant (p
Physicochemical water quality of Karabel, Çaltı, and Tohma brooks and blood biochemical parameters of Barbus plebejus fish: assessment of heavy metal concentrations for potential health risks
(2021-11-01) Demir T.; Mutlu E.; Aydın S.; Gültepe N.
The present study aims to comparatively examine the physical quality parameters of water samples taken from Karabel, Çaltı, and Tohma brooks in Sivas province and the blood biochemical parameters of blood samples of Barbus plebejus fish obtained from these waters. In periods when chemical pollution in water increased and decreased, it was determined that GLU and UA among blood biochemical parameters were significantly affected. Moreover, the potential risk levels of lead (Pb), copper (Cu), cadmium (Cd), and ferrous (Fe) for human health were compared to the international standards. Metal (Fe, Pb, Cu, and Cd) concentrations in the water were determined using atomic absorption spectrophotometer. The highest HQingestion values of Cd were found in Brook Çaltı, which were 0.0018 for adults and 0.1980 for children. THQ upper limit set by the United States Environment Protection Agency (USEPA) is < 1. It was determined that HQingestion, HQdermal, and THQ values of all the heavy metals were much lower than this limit. It was concluded that water quality parameters of samples taken from Karabel, Çaltı, and Tohma brooks on monthly basis for 12 months were not higher than the limits and the water qualities of brooks were determined to be “good”.
