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 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.Öğe ENVIRONMENTAL TOXICITY OF CADMIUM AND HEALTH EFFECT(Scibulcom Ltd, 2009) Dokmeci, A. H.; Ongen, A.; Dagdeviren, S.Environmental toxicology examines the fate and effects of contaminants in the environment. Exposures to heavy metals can affect human health both directly or indirectly by disrupting ecological systems that exist in rivers, lake, oceans, streams, wetlands, estuaries and other ecosystems. It is known that cadmium input to the aquatic environment through discharge of industrial waste, surface run off and deposition of cadmium also strongly absorbed onto sediments and soils. On the other hand, non-ferrous metal mines and human activities such as using phosphate fertilisers, burning coal, iron alloys, steel and cement and disposing household waste, represent a major source of cadmium release to the aquatic ecosystems. Cadmium can easily entered into the body by food chain, drinking water, smoking a cigarette or even breathing the air. Acute and chronic exposure to cadmium in both human and animals results in health diseases. Cadmium was classified as a potential human carcinogen under the EPA (1996) cancer guidelines. The aim of this study was to review the effect of cadmium on human health and ecosystem. In this study, the effects of cadmium on vacating, digestion, and digestive system was reported. It was observed that cadmium has caused kidney disease, severely irritated the stomach, vomiting and diarrhea, sometimes even sudden deaths.Öğe MICROELEMENTS IN THE LANDS OF THE AZERBAIJAN REPUBLIC(Scibulcom Ltd, 2006) Sahmurova, A.; Ongen, A.Microelements are necessary to support life. However, in larger or lower amounts, they may become more important and critical. They may be accumulated in biological systems and become a significant health hazard. The main scope of this study was to determine the amount of microelements in soil in order to evaluate the relation between microelement content of soil and its health effect in some regions in the Republic of Azerbaijan. Endemic health problems are widespread in the region. For instance, endemic goitre, a type of goitre that is associated with dietary iodine deficiency, has been seen frequently in some regions of the Azerbaijan and many researhers have been working on the relation between microelement content of soil and endemic goitre. During the study, six main regions were determined to collect soil samples and those sites were devided into sub-regions. Totally, 161 soil samples were collected and microelements such as cobalt(Co), copper(Cu), fluorine(F), manganese(Mn), molybdenum(Mo), zinc(Zn) and iodine(I) were measured and the results were compared with the samples where no endemic goitre were noticed. Measurements were also compared with the standards in order to evaluate the magnitude of the problem. Results revealed that the amount of microelements in the Republic of Azerbaijan soil samples varied in a large range even in the different parts of the same region. Especially, the amount of iodine in soil sample was measured low (average, 1.18-7.43 mg/kg) where endemic goitre was freguently seen. It is also revealed that not only the deficiency of iodine was a reason for endemic diseases but also other microelements take role in the existence of such problems in the Republic of Azerbaijan.
