A comparative analysis of water quality assessment methods for heavy metal pollution in karasu stream, Turkey
(2013-04-05) Sönmez A.; Hisar O.; Yanik T.
Heavy metals are among the most persistent of pollutants in aquatic systems due to their resistance to decomposition in nature. Four assessment methods (two pollution indexes and two fuzzy mathematical models - single-factor deciding and weighted average models) were used to check the level and characteristics of heavy metal pollution in the Karasů stream water. Several heavy metals such as Copper (Cu), Zinc (Zn), Manganese (Mn), Lead (Pb), Nickel (Ni), Cadmium (Cd) and Iron (Fe) were tested with these methods. A data set (12 months, total 180 measurements) was collected from 5 sampling points (A-E) of the River. The used criteria were classes, I-IV represents from clear to polluted one. Water quality was assessed as class IV from all water samples collected from the each station with single-factor index method. It was identified to be class IV from the samples of A, B, C and D stations, and class III from the sample of E station with the comprehensive index model. By using the fuzzy mathematical methods, the water quality were determined as classes of IV, IV, IV, II and II from the water samples of A, B, C, D and E stations respectively. Introduction of membership degree and weight of each factor to fuzzy mathematical models made the methods more reasonable in the field of water quality assessment. Therefore, these fuzzy mathematical methods might be quite convenient in evaluation of water pollution and classification considering the results of the present study. © by PSP.
A short report regarding the physicochemical properties of surface water quality in Karaçomak stream, Turkey
(2016-04-18) Suţan N.; Mutlu E.; Yanik T.; Dobre R.
Within the scope of present study, the water quality of stream Karaçomak in Kastamonu-Turkey was investigated. Water samples were collected from 9 stations selected on Karaçomak stream, considering the pollution points and the points, where the entrance of water into stream is high. The samples taken were analyzed in terms of water temperature, pH, dissolved oxygen, saltiness, electrical conductivity, chemical composition and heavy metal content, and for their genotoxic and cytotoxic potential. Physicochemical evaluation indicated that all samples had heterogeneous intensity of environmental influence, but the considerable impact was noticed for the third and seventh stations. The present study highlights the need for continuous evaluation of water pollution level, and is intended to help in mitigating the environmental impacts and improve environmental performance.
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
