Öğe ASSESSMENT OF HEAVY METAL CONTAMINATION IN SOIL AND WHEAT (Triticum Aestivum L.) PLANT AROUND THE CORLU-CERKEZKOY HIGHWAY IN THRACE REGION(Global Network Environmental Science & Technology, 2012) Ekmekyapar, F.; Sabudak, T.; Seren, G.Pollution caused by traffic activities is increasingly becoming a great threat to human health in the region of Thrace in north-west of Turkey. Thirty six soil and plant samples were collected from the vicinity of Corlu-Cerkezkoy Highway. The samples were taken at distances of, 1, 25, 50, 100, 250 and 500 m from the highway. The each plant sample was divided into two subsamples. One subsamples of each plant was washed with with distilled water, while other part was not washed and were analyzed without any washing. All samples were analyzed for their heavy metal concentrations (Pb, Zn, Cd, Cu, Ni, Mn, Cr and Fe). The results showed that the soils in the study area were polluted by Pb. The lead concentration in the soil showed values from 19 +/- 0.2 mg kg(-1) to 351 +/- 0.3 mg kg(-1) and found to be higher than the allowable maximum limits in soils. The manganese levels of soils were slightly high and varied from 182 +/- 0.1 mg kg(-1) to 806 +/- 0.1 mg kg(-1). In this study, metal concentrations of unwashed plant samples were higher than those of the washed ones. This study indicated that the heavy metal contents decreased with increasing distances from the highway in unwashed plants.Öğe COPPER AND CADMIUM CONTENTS IN GROUND AND SURFACE WATER IN CORLU, TURKEY(Scibulcom Ltd, 2008) Ongen, A.; Dokmeci, H.; Celik, S. O.; Sabudak, T.; Kaykioglu, G.; Dokmeci, I.Heavy metal Pollution is a quickly growing problem for water systems, Such as oceans, lakes, and rivers in the areas with intensive industry. There are several different ways that heavy metal pollution ends up in our oceans. lakes and bays. The four main ways are: burning heavy metal, heavy metal runoff, dumping or heavy metals, and tributary inflow. Roadways and automobiles are also considered to be one of the largest sources of heavy metals. Zinc, copper, and lead are three of the most common heavy metals released from road travel, accounting for at least 90 of the total metals in road runoff. Meanwhile. they are natural components of the Earth's crust. They can not be degraded or destroyed. To a small extent they enter Our bodies via food, drinking water and air. Heavy metals become dangerous when they tend to bioaccumulate. Since study area has been Under a heavy industrialisation period, alteration of natural water resources has been reported in the area. In order to evaluate the potential of this alteration heavy metal monitoring program was run in the area. In the region, drinking water is supplied by groundwater abstraction. Surface water has limited usage because of its low quality. Surface water has both organic and inorganic based Pollution related to uncontrolled agricultural and industrial activities. Both groundwater and Surface water samples were collected from over 30 sampling points. Cadmium and copper analyses were carried out via atomic absorption spectroscopy (AAS). Great variations in the results among the samples were recognised during analysis. Maximum concentrations for both cadmium and copper were determined in surface water samples as 202 ppb and 19 ppb, respectively. Analysis Of groundwater samples from municipal wells showed that copper and cadmium levels were under standards which Would harm people health.Öğe Determination of copper, zinc and lead contents in sunflower plants(Scibulcom Ltd, 2007) Sabudak, T.; Seren, G.; Kaykioglu, G.; Dincer, A. R.Trace elements are considered to be one of the main sources of pollution in the environment since they have a significant effect on its ecological quality. The determination of trace elements in plant samples is very important in monitoring environmental pollution. Recently, both international and the Turkish studies have drawn attention to the metal pollution of plant specimens. But, such a study has not been yet carried out in Corlu, Turkey. In this study the concentrations of trace elements (copper, zinc and lead) in the sunflower plants collected from Corlu, Turkey, were determined by flame atomic absorption spectrometry (FAAS). In the determinations by FAAS, a standard addition technique was used because of the influence of possible interference present in the sample tested. The area of the study included the textile factories in the vicinity of Corlu, which is a developing industrial center in the Trakya zone, Turkey. In addition, sunflower plants are the plants most grown in Corlu. The sunflower plants collected from the locations were broken into plants parts (root, stern, leaves, head, seed), washed with distilled water and dried at 110 degrees C for 24 h. Then plant parts were digested by wet ashing procedures. The concentrations of Cu, Zn and Ph elements in plant parts were determined by FAAS. The Cu concentrations were 3.25 +/- 0.09, 2.30 +/- 0.05, 7.80 +/- 0.20, 4.70 +/- 0,11 and 11.25 +/- 0.12 ing kg(-1), the Zn concentrations were 5.15 +/- 0.17, 18.8 +/- 0.69, 20.3 +/- 0.45, 2.35 +/- 0.06 and 40.4 +/- 0.33 mg kg(-1) in root, stern, leaf, head and seed, respectively. The lead concentrations were not detected by FAAS because of the very low analyte concentration. The obtained results were compared to those in literature.Öğe DETERMINATION OF NICKEL AND LEAD CONTENTS IN SOIL AND PLANT IN CORLU, TURKEY(Scibulcom Ltd, 2008) Sabudak, T.; Kaykioglu, G.; Ongen, A.; Dokmeci, H.; Celik, S. O.; Dokmeci, I.The extent of the environmental pollution derived from industrial activities has intensive adverse effects in Corlu, Turkey. In the study area industrialisation has been growing rapidly and uncontrolled since 1970's. Corlu has a great importance regarding its industrial improvement both for Thrace region and Turkey. This consequence has not yet been evaluated sufficiently in the view of environmental concerns. Due to environmental cycle, trace elements, emanating from atmospheric and industrial Pollution accumulate, in soil and affect the ecosystem nearby. These elements may accumulate in soil, collected in plant or infiltrated 10 ground water. If they accumulate in a plant the), may reach to food chain and become harmful for human life. Hence, the investigation of trace elements in soil and plant samples is very important in the point of environmental Pollution, especially for plants. In the present study, levels of Pb and Ni in soil and plant samples collected from Corlu, Turkey, were determined by flame atomic absorption spectrometry (FAAS). The maximum levels of trace elements were determined as 52.91 mg Pb kg(-1) and 40.68 mg Ni kg(-1) in soil and 80.90 mg Pb kg(-1) in plant parts. Phytotoxic Pb amount ill the some samples was observed. The nickel in plant samples was not in detectable limits for FAAS.
