Measuring the direct and indirect effects of human actions is crucial to increasing awareness and prompting behavioral change. The carbon footprint is a widely used method of measurement in this regard. This study comprises three parts. The first part involved providing pre-training to students and teachers at Lokman Hekim Vocational and Technical Anatolian High School, which has 304 students and 29 teachers. A 15-question awareness questionnaire was then administered to determine their understanding of carbon footprints. The results showed that the students were knowledgeable about climate change and global warming but lacked sufficient understanding of carbon footprints. In the second part of the study, a face-to-face measurement study was conducted with 295 students to calculate the annual average amount of CO2 emitted by the students based on categories. The results showed that the studen...

In batch tests, the highest removals for CEH (Chlorination-Extraction-Hypochlorite) bleaching sequence [65% organic halides (AOX) 84% color] were obtained with 2 g/l acetate concentration in 10 days under non-shaking conditions. Experiments in shaking flasks containing Tween 80 produced 60% AOX, 79% color removals in 10 days. This removal efficiency was also in accord with gas chromatography analysis indicating drastic reductions at low molecular weight adsorbable organic halogen compounds.

The Dalyan Channel network connects lake to the Mediterranean Sea is one of the most important reproduction areas for Mediterranean Sea turtles. The objectives of the present study are to evaluate the nel by evaluating historical water quality data to perform trend analysis for; (i) concentration trends; (ii) load estimation (mass of pollutants delivered); (iii) TN:TP Ratio (trophic showed that TSI (trophic state index) values of both SD (secchi depth) and TP (total phosphate) remained within the range of o be P limited with a few exceptions. The lake has poor water quality index (POOR WQI) between 2007 and 2011. This is mainly due to land-Dalyan SEPA and drains directly into fish farming, TP concentration incidence also increased after fish farming from 2008 to 2011. This study also revealed that activities like touristic boat trips performed in Dalyan Channel didn't significantly affect the water quality class of channel in terms of NO2-N, TP concentrations and the number of total coliforms.

The batch experiments were conducted in shake flasks using PCP as co-substrate resulting in around 56% PCP removal by the fungus. Experiments in shake flasks not containing acetate but Tween 80, produced 86% of PCP and 53% of 2-chlorophenol removals in 21 days. PCP was also fed to a column reactor with an adsorbable organic halogens (AOX) concentration of 63.4 mg/l. On the fourth day of operation, AOX removal was 77%, but this steadily dropped to 18.8% on the 18th day.

Most of the organic halides (AOX) and colour from pulp bleaching units are discharged to the receiving basins without being fully treated. A fungus. which is able to affect over 50% AOX and colour removals from soft-wood bleachery effluents within two days contact time. have been Isolated in this laboratory. Optimum condition for dechlorination by this fungus in batch tests was detenmned as pH 5.5 and 25°C. The low agltallon speeds required by the fungus indicated its tendency towards immobilisation on a solid substrate. Glass wool was chosen as a suitable immobilising matrix to be used in the continuous expenments. An up-flow column was packed with glass wool and operated successfully for over one and half years with AOX removals around 70% in 7-8 hours contact time. Fungal dehalogenation required very low supplemental carbon and no DO. The fungal reactor was also effective in dechlorinating polychlorinated aromatics. e.g. PCP. though dehalogenation ability decreased considerably with the chlorinated aliphatics. High PCP concentrallons presumably toxified the fungus. even at short exposures, thereby irreversibly damaging the column reactor.

However, in this study it has been shown that biological systems can adapt to Ni (II) and Cr (VI) when their concentration is below 10 and 20 mg/L, respectively. The aim of this study was to evaluate the effect of Ni (II) and Cr (VI) on the lab-scale rotating biological contactor process. It was found that, addition of Ni (II) up to 10 mg/L did not reduce the chemical oxygen demand removal efficiency and on the contrary concentrations below 10 mg/L improved the performance. The influent Ni (II) concentration of 1 mg/L was the concentration where the treatment efficiency produced a maximum COD removal of 86.5%. Moreover, Ni (II) concentration above 10 mg/L was relatively toxic to the system and produced lower treatment efficiencies than the baseline study without Ni (II). Turbidity and suspended solids removals were not stimulated to a great extent with nickel. Addition of Ni (II) did not seem to affect the pH of the system during treatment. The dissolved oxygen concentration did not drop below 4 mg/L at all concentrations of Ni (II) indicating aerobic conditions prevailed in the system. Experiments conducted with Cr (VI) revealed that addition of Cr (VI) up to 20 mg/L did not reduce the COD removal efficiency and on the contrary concentrations below 20 mg/L improved the performance. The influent Cr (VI) concentration of 1 mg/L was the concentration where the treatment efficiency produced a maximum COD removal of 88%. Turbidity and SS removals were more efficient at 5 mg/L Cr (VI) concentration, rather than 1 mg/L, which lead to the conclusion that 5 mg/L Cr (VI) concentration is the optimum concentration, in terms of COD, turbidity and SS removals. Similar with Ni (II) experiments, addition of Cr (VI) did not significantly affect the pH value of the effluent. The DO concentration remained above 5 mg/L.

The area between the Köyceğiz Lake and the Mediterranean Sea is covered with four small lakes and several canals. The surroundings of the lake, canals and forests have a great potential as a reproduction areas for Mediterranean Sea turtles (Caretta caretta) and sheltering place for various animals. In the vicinity of this system there are agricultural areas and small settlements. In this region the most important economic activities are tourism and fisheries. However, the lake is currently threatened by pollution because of (1) non-point source pollution (agriculture); (2) point sources (land-based fish farms); (3) inefficient sewerage systems; (4) uncontrolled soil erosion in its drainage basin; (5) inappropriate flood control measures; and (6) channel traffic. This study evaluates the influence of its influent creeks namely Namnam and Yuvarlakçay Creek on the water quality of Köyceğiz Lake, mainly because the creeks are believed to be responsible for the major pollutant load reaching the lake. Accordingly, this study demonstrates (1) change in the water quality of Köyceğiz Lake from 2006 to 2007; (2) the water quality classification of the major influent creeks feeding Köyceğiz Lake; and (3) how land-based fish farm influences Yuvarlakçay Creek water quality in a Köyceğiz-Dalyan Specially Protected Area.

In the first step of this concept, hydrogen will be produced from the low‐salinity seawater by electrolysis utilizing the onboard renewable energy. Part of the hydrogen produced will be used in the second step, which is the major production step, claiming the H2S gas, which is exceptionally rich in the seawater. The hydrogen and sulfur products will be shipped by hydrogen‐powered shuttle ships to the nearby city of Sinop to blend hydrogen with the natural gas (NG) to form a hydrogen city. Thus this project presents a novel coupling of the land‐side and the sea‐side operations with renewable energy and hydrogen in an exergy‐based minimum CO2 emissions responsibilities. This on‐board H2S exploration concept for hydrogen and sulfur production is compared with the current NG explorations in the Black Sea and the use of NG on the landside. A detailed comparison of the total carbon footprint shows that NG explorations in the Black Sea will be responsible for direct and indirect‐nearly avoidable (due to exergy destructions) CO2 emissions, while the ever‐increasing H2S threat faced by all Black Sea countries will remain at an increasing rate. A new exergy‐based optimum H2S claim depth calculation and control algorithm for onboard operations have also been developed and designed, which shows that economy‐based optimization—if ever exists—will be responsible for nearly avoidable CO2 emissions, while the on‐board hydrogen production and utilization on the land side have a minimal environmental footprint. None of the earlier studies available in the literature concerning the exact harmful effects of hydrocarbons address exergy rationality. Renewable energy systems like wind turbines and solar energy systems, along with other renewable and waste energy systems like geothermal and wave energy are mostly treated individually, which are not free from large exergy destructions. Therefore, future energy plans with environmental concerns must be carried out from the source to the very last point of demand sectors. This is the specific attribute of this research.

The European Green Deal has targets covering many different sectors, including construction, biodiversity, energy, transportation, and food, which include the enactment of new laws on green rainwater infrastructure. Green stormwater infrastructure not only controls stormwater volume and timing but also supports the benefits ecosystems bring to us. Stormwater is defined as rainwater or melted snow runoff from streets, lawns, and other areas. When rainstorm water is absorbed into the soil, it is filtered and eventually replenishes aquifers or flows into streams and rivers. Runoff carries sediments, nutrients, or other pollutants into water sources that degrade water quality, threaten drinking water supplies, and complicate water treatment processes. When drought concentrates...

It demonstrates the potential climate change impact of a sequential batch reactor (SBR) and constructed wetland on treating domestic wastewater by giving methods for calculation of their greenhouse gas emissions in terms of N 2 O and CH 4. Are wastewater treatment plants sustainable? What aspects determine sustainability? Do tertiary wastewater treatment plants and constructed wetlands (CWs) have less global warming potential (CO 2 emissions) and less energy use than conventional treatment? In accordance with the literature, greenhouse gas calculations of this study showed that CWs and SBR WWTPs do not contribute to global warming negatively.

Je tiens pour une bizarrerie de notre époque qu'on puisse déformer cette simple intuition du fait esthétique pour y voir la preuve que l'art est dépourvu de signification, étranger à l'homme et sans intérêt pour lui. Admettre la différence entre la vie et l'art, le « fossé ontologique » qui sépare un produit de l'esprit, une structure de langage, des événements de la vie « réelle » que ce produit reflète, ne veut pas dire et ne peut vouloir dire que l'oeuvre d'art n'est rien qu'un jeu de formes creux, coupé de la réalité. Le rapport de l'art à la réalité n'est pas aussi simple que le supposent les anciennes théories naturalistes de 1' « imitation » ou de la reproduction, ou le « reflet » des marxistes. Le « réalisme » n'est pas la seule méthode artistique. Cela exclut les trois-quarts de la littérature mondiale et le rôle que jouent l'imagination et « l'édification » de la personnalité s'y trouve minimisé 1 .

The Turkish Government is aware of the importance of the preservation of natural ecology and thereby the environmental conservation of many species in their natural habitat. This paper provides critical assessments of the problems and possible solutions in the identification, implementation and management of the Specially Protected Areas (SPAs) system by giving basic information about stakeholders and their responsibilities that currently offer nature conservation in Turkey. The goals of the article are to analyze how the SPAs interface with the local people, especially the villagers who have dwelt there before SPA designation and how people-SPA conflicts resolved; to show how effective the SPA conservation objectives have been; to outline the significance of informing and empowering people in nature conservation for the protected area management and to show the importance of planning at all levels during protection of the natural, archeological and cultural values of the SPAs.

In the first step of this concept, hydrogen will be produced from the low‐salinity seawater by electrolysis utilizing the onboard renewable energy. Part of the hydrogen produced will be used in the second step, which is the major production step, claiming the H2S gas, which is exceptionally rich in the seawater. The hydrogen and sulfur products will be shipped by hydrogen‐powered shuttle ships to the nearby city of Sinop to blend hydrogen with the natural gas (NG) to form a hydrogen city. Thus this project presents a novel coupling of the land‐side and the sea‐side operations with renewable energy and hydrogen in an exergy‐based minimum CO2 emissions responsibilities. This on‐board H2S exploration concept for hydrogen and sulfur production is compared with the current NG explorations in the Black Sea and the use of NG on the landside. A detailed comparison of the total carbon footprint shows that NG explorations in the Black Sea will be responsible for direct and indirect‐nearly avoidable (due to exergy destructions) CO2 emissions, while the ever‐increasing H2S threat faced by all Black Sea countries will remain at an increasing rate. A new exergy‐based optimum H2S claim depth calculation and control algorithm for onboard operations have also been developed and designed, which shows that economy‐based optimization—if ever exists—will be responsible for nearly avoidable CO2 emissions, while the on‐board hydrogen production and utilization on the land side have a minimal environmental footprint. None of the earlier studies available in the literature concerning the exact harmful effects of hydrocarbons address exergy rationality. Renewable energy systems like wind turbines and solar energy systems, along with other renewable and waste energy systems like geothermal and wave energy are mostly treated individually, which are not free from large exergy destructions. Therefore, future energy plans with environmental concerns must be carried out from the source to the very last point of demand sectors. This is the specific attribute of this research.

Bu sanayiden ortaya çıkan atıksular BOİ ve KOİ parametreleri bakımından normalde bir miktar biyolojik olarak arıtılabilir olmakla birlikte biyolojik arıtım genellikle tam olarak gerçekleşemez. Bu atıksulara özgü olarak ortaya çıkan organik halidler (AOX) ve renk parametreleri biyolojik arıtıma girmeden doğrudan alıcı ortama verilirler. Organik halidler toksik, mutajenik ve kanserojenik özellikler göstermekte ve bunları metabolize edecek gerekli enzim sistemlerinin doğada yaygın bulunmaması nedeniyle kalıcı özellik gösterirler. Son yıllarda kloroligninleri parçalayabilen funguslar izole edilmiştir. Bu proje çerçevesinde yürütülen çalışmalar esnasında % 60 dan fazla renk ve A0X arıtabilen bir fungus izole edilmiş ve Penicillium sp. olarak tayin edilmiştir. Erelenlerde yapılan kesikli çalışmalar sonucunda bu fungusun optimum pH'sının 5, optimum sıcaklığının 25 °C olduğu bulunm...

The European Green Deal has targets covering many different sectors, including construction, biodiversity, energy, transportation, and food, which include the enactment of new laws on green rainwater infrastructure. Green stormwater infrastructure not only controls stormwater volume and timing but also supports the benefits ecosystems bring to us. Stormwater is defined as rainwater or melted snow runoff from streets, lawns, and other areas. When rainstorm water is absorbed into the soil, it is filtered and eventually replenishes aquifers or flows into streams and rivers. Runoff carries sediments, nutrients, or other pollutants into water sources that degrade water quality, threaten drinking water supplies, and complicate water treatment processes. When drought concentrates...

It demonstrates the potential climate change impact of a sequential batch reactor (SBR) and constructed wetland on treating domestic wastewater by giving methods for calculation of their greenhouse gas emissions in terms of N 2 O and CH 4. Are wastewater treatment plants sustainable? What aspects determine sustainability? Do tertiary wastewater treatment plants and constructed wetlands (CWs) have less global warming potential (CO 2 emissions) and less energy use than conventional treatment? In accordance with the literature, greenhouse gas calculations of this study showed that CWs and SBR WWTPs do not contribute to global warming negatively.

Je tiens pour une bizarrerie de notre époque qu'on puisse déformer cette simple intuition du fait esthétique pour y voir la preuve que l'art est dépourvu de signification, étranger à l'homme et sans intérêt pour lui. Admettre la différence entre la vie et l'art, le « fossé ontologique » qui sépare un produit de l'esprit, une structure de langage, des événements de la vie « réelle » que ce produit reflète, ne veut pas dire et ne peut vouloir dire que l'oeuvre d'art n'est rien qu'un jeu de formes creux, coupé de la réalité. Le rapport de l'art à la réalité n'est pas aussi simple que le supposent les anciennes théories naturalistes de 1' « imitation » ou de la reproduction, ou le « reflet » des marxistes. Le « réalisme » n'est pas la seule méthode artistique. Cela exclut les trois-quarts de la littérature mondiale et le rôle que jouent l'imagination et « l'édification » de la personnalité s'y trouve minimisé 1 .

The Turkish Government is aware of the importance of the preservation of natural ecology and thereby the environmental conservation of many species in their natural habitat. This paper provides critical assessments of the problems and possible solutions in the identification, implementation and management of the Specially Protected Areas (SPAs) system by giving basic information about stakeholders and their responsibilities that currently offer nature conservation in Turkey. The goals of the article are to analyze how the SPAs interface with the local people, especially the villagers who have dwelt there before SPA designation and how people-SPA conflicts resolved; to show how effective the SPA conservation objectives have been; to outline the significance of informing and empowering people in nature conservation for the protected area management and to show the importance of planning at all levels during protection of the natural, archeological and cultural values of the SPAs. Keywords Issues Á Local people Á Nature conservation Á Protected area Á Turkey The 2003 United Nations List of Protected Areas presents data on 102,102 protected areas covering 18.8 million km 2. Within this overall figure, there are 68,066 protected areas with IUCN Management Categories. In addition, there are 4,633 internationally designated sites like SPA's of Turkey (UNEP 2003).
