Concentrations of metals were determined in the gills, liver, kidney, heart and muscle in Capoeta umbla caught from six stations from the Munzur River system. Metal concentrations in the tissues tended to vary significantly among stations (p < 0.05). Liver (Cu, 10.10 +/- A 0.23-23.03 +/- A 9.37 ppm; Zn, 14.67 +/- A 3.01-21.82 +/- A 2.39 ppm; Cd, 18.04 +/- A 4.56-52.69 +/- A 10.65 ppb and Fe, 28.87 +/- A 6.78-115.11 +/- A 34.87 ppm) and kidney (Cu, 1.80 +/- A 0.25-3.70 +/- A 0.62 ppm; Zn, 20.81 +/- A 0.37-29.36 +/- A 0.70 ppm; Cd, 132.06 +/- A 5.29-639.51 +/- A 20.14 ppb and Fe, 24.40 +/- A 1.98-59.39 +/- A 1.97 ppm) tissues showed higher metal concentrations than other tissues. It seems that metal contamination in the river is too high for the health of fish and the people who eat them. The geographical locations of catch, season, nature of diet, and the size of fish used for analyses might lead to different metal concentration in the same fish species.

İncele - MakaleAçık Erişim2011Assessment of Some Heavy Metals in Drinking Water Samples of Tunceli, Turkey
Kaplan, Olcay; Yildirim, Nuran Cikcikoglu; Yildirim, Numan; Tayhan, Nilgun
The drinking water quality is associated with the conditions of the water supply networks, the pollution and the contamination of groundwater with pollutants of both anthropogenic and natural origin. In this study, water samples were taken from four different waterworks in Tunceli, Turkey and heavy metals concentrations (As, Cu, Cd, Cr, Pb, Ni and Hg) were measured. Four sampling sites were pre-defined in different locations of the city. The obtained results showed that, the heavy metals concentrations in water samples did not exceed the values of WHO (World Health Organization), EC (Europe Community), EPA (Environment Protection Agency) and TSE-266 (Turkish Standard) guidelines.

Kaplan, Olcay; Ince, Muharrem; Yaman, Mehmet
Cd concentrations in mobile phases of soil are more representative than total Cd concentration for estimating Cd bioavailability, physicochemical reactivity and mobility. In this study, selective sequential extraction procedures were used to determine Cd in different soil phases. Soil samples and plants grown in these soils were collected from a serpentine and copper-mining area in Maden-Elazig-Turkey. The extracted fractions were exchangeable/carbonate, reducible-iron/manganese oxides, oxidizable-organic matter and sulfides, and residual phases except silicates. Concentrations of Cd in soils and plant samples were determined by flame atomic absorption spectrometry and inductively coupled plasma-mass spectrometry. We found that Cd concentrations in the EDTA and NH(2)OH center dot HCl extracts are higher in most soil samples compared to the other extracts. We conclude that Cd levels in mobile phases are unexpectedly high. The observed Cd concentrations are in ranges of 0.03-3.4 mg kg(-1) for soil and 0.02-2.5 mg kg(-1) for plant parts. The percentages of cadmium up to 56% in exchangeable and carbonates fractions were observed to be significantly higher than in those values less than 2% reported in literature. This study has shown that the modified extraction method can be usefully applied to determine Cd concentrations in potentially mobile phase of soil. Furthermore, it was concluded that Brassicasea and Rumex leaves can be used as hyperaccumulator plants because their translocation factor and/or enrichment coefficient values were found to be higher than 1.0.

Kaplan, Olcay; Kaya, Gokce; Yaman, Mehmet
Copper (Cu) is an essential trace element for all living organisms; however, excess amounts in soil, plants, and food have negative impacts on the environment and human health. The aim of this study was to determine Cu levels in different chemical phases of soils and the relationship between Cu levels in soil phases and concentrations in plants. Soils and plants grown in these soils from an industrialized area in Turkey were analyzed using a selective and four-stage sequential extraction procedure. Copper levels in exchangeable fractions were found up to 658 mg kg(-1) while total levels were in the range of 133-5609 mg kg(-1). Copper concentrations in plant parts (roots and stem) were in the range of 2.6-240 mg kg(-1). The exchangeable forms of Cu were in the range of 3-22% of total Cu concentrations. The relationships were observed between soil Cu and Rumex plant Cu, and soil Cu and root of Brassicasea plant Cu.

This study explored the chemical and microbiological contamination of drinking water from eight towns in Tunceli, Turkey Polycyclic aromatic hydrocarbons and epichloridine were extracted by liquid solid extraction and analyzed by using HPLC, volatile organics were analyzed by GC-MS and acrylamide was analyzed by GC Escherichia coli and total conform detection followed a membrane filtration method Enterococci were detected and numerated by membrane filtration method Most commonly found chemical pollutants were benzene, benzo[a]pyrene (BaP), 1-2 dichloroethane, epichloridine, tetrachloroethane, trihalomethane and acrylamide E coli, total conform and enterococci were also found in the drinking water Our results indicate that generally chemical and microbiological contaminations were found below the guidelines for drinking waters given by the World Health Organization, because of the fact that in the sampling area there is not any contaminating source So, according to results these water samples are fit for drinking (C) 2010 Friends Science Publishers

Fishes are largly used for the assessment of aquatic environment quality and are accepted as bioindicators of environmental pollution. This study evaluated haematological and biochemical responses of Capoeta trutta captured in Munzur River, Tunceli, Turkey. Blood and biochemical parameters (Sodium (Na), Potassium (K), Calcium (Ca), Phosphorus (P), Chlorine (Cl) and Iron (Fe)) were determined. The values of Red Blood Cell (RBC) Haemoglobin (Hb), Haemotocrit (Ht), Haemoglobin Concentration (MCHC), Platelet Count (PLT), Mean Platelet Volume (MPV), Plateletcrit (PCT), Platelet Distribution Width (PDW) from examined haematological parameters were found as 0.67+/-0.09 10(12) L(-1), 13.5+/-0.90 g dL(-1), 14.78+/-0.19%, 218.40+/-4.29 fL, 194.75+/-15.36 pg 108.52+/-1.09 g dL(-1), 34.12+/-5.89 10(9)L(-1), 11.92+/-1.65 fL, 0.061+/-0.01% and 19.77+/-1.71 fL, respectively. The values of Fe, Cl, P, Ca, K and Na from examined biochemical parameters were determined as 91.75+/-28.27 g dL(-1), 92.00+/-4.02 mmol L(-1), 13.20+/-1.26mg dL(-1), 11.65+/-0.74 mmol L(-1), 1.30+/-0.21 mmol L(-1) and 132.5+/-3.90 mg dL(-1) respectively. Observation of blood parameters allows the most rapid detection of changes in fish after the exposure to xenobiotics. It can conclude that hematological and biochemical parameters could be ranked as possible biomarkers of pollution.

For over ten years, there has been a considerable interest in determination of acrylamide in foodstuffs. It was known that both protein-rich and carbohydrates-rich foods cooked at high-temperatures can cause acrylamide formation. However, carbohydrates-rich foods such as potato chips and biscuit samples have been the common studied foods compared with protein-rich foods such as meat samples. In this study, determination of acrylamide in these two group foods was examined using HPLC-MS. For this purpose, firstly, the parameters that are thought to affect the response in the HPLC-MS analysis were optimized. The optimized conditions were found to be 0.3 ml min(-1) for flow rate of mobile phase, 40 mu l for injection volume, 5 degrees C for column temperature and 70 V for fragmentor potential. The optimized method was applied for the determination of acrylamide levels in Turkish foodstuffs including grilled meat and chicken samples, potato chips, coffee and biscuit. The obtained concentrations for all studied foods were in the range of 20-250 mu g kg(-1). The results showed that acrylamide concentrations highly varied depending on the kind of food samples.
