The present study was undertaken as part of the first application and evaluation of the BREF (Best Available Techniques; BAT Reference Document) Textile Document within the context of the European Union's Integrated Pollution Prevention and Control (IPPC) Directive to a large scale textile mill in Turkey. The BAT requirements for the denim manufacturing textile mill were selected in cooperation with the factory management. Detailed mass balance calculations were conducted to evaluate the overall effect of the selected BAT options. The initial findings indicated that the adoption of the selected BAT options resulted in considerable savings in water and energy consumption in the mill. Besides the installation of flow meters and use of semi-counter current rinsing in the most water-intensive processes, minimization of wash waters in the water softening plant, reuse of the concentrate stream from the reverse osmosis plant and compressor cooling waters provided a 29.5% reduction in the total specific water consumption of the mill, reaching the lower limits suggested by the BREF Textile Document. In terms of energy consumption, use of waste heat from finishing wastewater streams in heating up the wash waters, heat insulation and maintenance applications in addition to BAT measures taken for water minimization reduced specific energy consumption by 9% achieving the limits set by the BREF Textile Document. 相似文献

Fifteen bottled mineral waters purchased at random all over Turkey were analyzed for their chemical composition by OPTIMA-2000
ICP-AES Perkin Elmer techniques. Results show a wide spread in the chemical specification of these mineral waters, with differences
in chemical composition observed in the regions being due to the geological environment and the majority of bottled mineral
waters exceeding the pH limit of Turkish drinking water standards. When the concentrations of elements are evaluated, it can
readily be seen that generally there are three types of mineral water in Turkey. The concentrations of Al, B, Ba, Cd, Cu,
Cr, Fe, Mn Pb and Zn in mineral water were compared with the limits established by the Turkish Standard for Natural Mineral
Waters (Turkish Official Gazette 2004); water standards prepared by World Health Organization (2006) and the United States of America Environmental Protection Agency (US EPA) drinking water standards (1993). Such a comparison shows that, except for Ba and Mn, the concentrations of the other heavy metals are lower than the limit
of the US.EPA in Turkey. Some parameters examined were found to comprise strong correlations pair-wise. 相似文献

Unauthorised development and seismic hazard vulnerability: a study of squatters and engineers in Istanbul, Turkey 总被引:2,自引:0,他引:2
Green RA 《Disasters》2008,32(3):358-376
Many cities in developing nations have experienced an influx of poor migrants in search of work. This population influx has often been accommodated through land squatting, irregular construction and unauthorised housing. For the urban poor, this has resulted in immediate affordable housing; however, this housing frequently has long-term vulnerability to natural hazards. This article examines the ways in which squatters in Istanbul, Turkey, understand the seismic vulnerability of their unauthorised housing. Distrust of professional engineers and contractors has led Istanbul squatters to believe that self-built housing will not only be less costly but also safer than commercially built housing. The impact of residents' risk perceptions on their vulnerability to natural hazards is examined through a comparison of social attitudes regarding safe housing and the quality of unauthorised construction. This comparison highlights how squatters' risk perceptions necessitate innovative means of reducing vulnerability in unauthorised neighbourhoods of developing cities. 相似文献

This case study examines the coastal zone problems focusing on the existing conflicts between tourism and commercial activities on the coasts of Edremit Bay, Turkey, and attempts to suggest solutions to these problems. Edremit Bay is a characteristic example of such a conflict in collective use of natural resources. The study area, with its 100-km-long sandy beach, naturally attracts different coastal user groups with different beneficial expectations: in terms of rest and recreation for one group and commercial gain offered in a variety of ways for another group. Significant coastal zone problems exist in the study area. Deterioration of shoreline due to tourism activities and illegal constructions, damage to the coastal ecosystem due to domestic/industrial wastewater discharges and some agricultural activities, and disordered urbanization are only a few of the many problems. The data presented here were partly derived from field study and partly collected from local state or private organizations. In this study, it is emphasized that there is a need for viable economic and environmental strategies to be designated in Edremit Bay, Turkey, in order to provide sustainable resource use. For this purpose, an integrated project together with a relevant planning chart including subprojects is also suggested. The success of a local environmental protection management project depends on active participation of all stakeholders including governmental organizations and nongovernmental organizations. 相似文献

In this study, the concentrations of Co, Ni, Fe, Cu, Mn, Pb, Cr, and Cd were determined in 15 cigarette brands from Turkey by flame atomic absorption spectrometry (FAAS). A wet digestion method was employed to cigarette samples. The mean values obtained for Co, Ni, Fe, Cu, Mn, Pb, Cr, and Cd were 1.2, 4.1, 134, 14, 66, 3.7, 5.0, and 1.1?µg?g?1, respectively, i.e., in the order of Fe?>?Mn?>?Cu?>?Cr?>?Ni?>?Pb?>?Co?>?Cd. The results were compared with the literature values for other international cigarette brands. 相似文献

Although environmental management in Turkey is evolving, its performance needs to be assessed in terms of the extent to which polluters and dischargers are complying with their legal obligations. In spite of this necessity, however, not a single study evaluating the effectiveness of command-and-control strategy of environmental management has been conducted. It is for this reason that it was decided to conduct an analysis of the impact of environmental legislation on a major industrial area in Turkey. Accordingly, Turkish environmental legislation was analyzed, and all relevant obligations and responsibilities of industry are identified. Based upon this appraisal, a questionnaire was prepared and used to conduct interviews in Tuzla, Istanbul. From the results, it can be concluded that environmental compliance performance of industry is low. The total of 92 parameters has been questioned. Fifty-three parameters have been found as satisfactory compliance, whereas 26 parameters have been classified as partial compliance and 13 as unsatisfactory compliance. The most important reason for inadequate performance is the lack of an effective national and local environmental compliance management system. The other leading reasons are found to be low-level environmental consciousness of the people, absence of environmental management system at the sites, inadequacies in environmental subsidies, and insufficiencies in public environmental infrastructure. Four recommendations are made to increase the effectiveness of compliance management: establishing an effective environmental compliance management system, accelerating public investment for environmental infrastructure, developing financial subsidies and incentive schemes for environmental investments, and encouraging voluntary initiatives. 相似文献

Needs assessment of the displaced population following the August 1999 earthquake in Turkey 总被引:1,自引:0,他引:1
In August 1999 a major earthquake struck north-western Turkey. An assessment followed to identify the immediate needs of the displaced population. A random cluster sample of displaced families living in temporary shelter outside of organised relief camps was designed. Representatives of 230 households from the four communities worse affected by the earthquake were interviewed. Most families lived in makeshift shelters (84 per cent), used bottled water (91 per cent), obtained food from relief organisations (61 per cent), had access to latrines (90 per cent), had a member on routine medication (53 per cent) and obtained information by word of mouth (81 per cent). Many respondents reported having family members who were over the age of 65 (32 per cent) or under age three (20 per cent), who were pregnant (6 per cent), or who had been ill since the earthquake (64 per cent). The greatest immediate need reported by most families was shelter requirements (37 per cent), followed by food (23 per cent) and hygiene requirements (19 per cent). Ten days after the earthquake, basic environmental health needs of food, shelter and hygiene still predominated in this displaced population. Significant portions may have special needs due to age or illness. 相似文献
