The TD-7 drainage channel has been exposed to wastewater discharges of different characteristics from multiple sources, due to industrial establishments and dense settlement in the vicinity. In this study, seasonal changes of the characterization of the water carried by the channel, ...

Landfills are still the most widely used solid waste disposal method used across the world. Leachate generated from landfill areas exerts environmental risks mostly on surface and groundwater, with its high pollutant content, most notably metals, which cause an unbearable lower water quality. During dumping or after the capacity of the landfill has been reached, a decontamination and remediation program should be taken for the area. This study was conducted to assess the capacity and efficiency of Pennisetum clandestinum, a prostrate perennial plant, to accumulate chromium (Cr), copper (Cu), iron (Fe), nickel (Ni), zinc (Zn) and lead (Pb). Leachate, taken from the Sofulu Landfill Site, was given to Pennisetum clandestinum for 180 days, in 3 dilution sets as 1/1, 1/2 and 1/4, in batch configuration. An additional control set was also installed for comparison. Results showed that, even though the metal content of soil had risen, plants accumulated 2 to 8.5 times higher concentrations ...

Since, landfill areas are still the most widely used solid waste disposal method across the world, leachate generated from landfills should be given importance. Leachate of landfills exerts environmental risks mostly on surface and groundwater with its high pollutant content, which may cause unbearable water quality. This leads to the obligation for decontamination and remediation program to be taken into progress for the landfill area. Among a number of alternatives to cope with leachate, one is to employ the technology of phytoremediation. The main objective of this study was to determine the N accumulation ratios and the effects of landfill leachate in diluted proportions of chosen ratios (as 1/1, 1/2, 1/4, 0), on the growth and development of Cynodon dactylon, Stenotaphrum secundatum, Paspalum notatum, Pennisetum clandestinum, Mentha piperita, Rosmarinus officinalis, Nerium oleander, Pelargonium peltatum and Kochia scoparia species. In order to simulate the actual conditions of ...

The aim of this study was to assess environmental attitudes and behaviour of students at Faculty of Agriculture in Çukurova University, Turkey. 240 undergraduate university students were surveyed. It was found out that majority of students (80.0%) used public media as a main source of information about environmental issues. Rural students were more concerned about environmental issues than urban ones

Rapidly growing population and industrialization brought about the enormous need for energy, alongside the environmental problems. Since biofuel energy is inexhaustible, it is becoming increasingly important to address the energy problem. Today, it is possible to classify biomass energy into two classes: classical and modern. Classical biofuel utilization is the simple burning of wood obtained from tree cutting and animal wastes, where modern biofuel application consists of a variety of fuels produced from various sources. Turkey’s potential for biofuels is estimated to be around 45 Mg. As a renewable energy, it’s been under the Renewable Support Scheme by regulation for more than a decade now. By the end of 2016, installed biofuel electricity generation capacity had reached 468 MW with 2 billion kWh realized (~0.7% of national demand). The aim for 2023 is reaching at least 1000 MW (which will be around 1.3% by then). Many analysts believe that the potential for development is highe...

(bzs. rnk.), tablo ; 29 cm.Anaerobik arıtma sistemlerinde bor içerikli atıksu etkisinin gözlenmesi amacı ile, mezofilik şartlarda (35ºC), anaerobik reaktörlerde farklı bor konsantrasyonları altında performans karakterleri gözlenmiştir. Çalışmada, bira fabrikası atıksu arıtmasından alınan çamurla aşılanan, kesikli ve sürekli olmak üzere iki farklı kurguda düzenekler kullanılmıştır. Bor kaynağı olarak borik asit reaktörlere beslenmiştir. Kesikli çalışmalarda, sabit organik yükleme ile artan bor konsantrasyonları (0,5, 1, 2, 5, 10, 25, 50 ve 100 mg B/L) test edilmiş, kontrol reaktörüyle kıyaslanarak, 2 mg bor konsantrasyonunda inhibisyon etkisi görülmeye başlanmıştır. Sürekli çalışmalarda ise, yukarı akışlı anaerobik çamur yataklı rektörler sabit hidrolik bekletme süresi (12 saat) şartlarında, üç farklı organik yüklemede (2, 4 ve 8 g KOİ/L?gün) artan konsantrasyonlarında bor (0,5, 2...
