Recently, heavy metals pollution due to industrialization and urbanization, use of untreated wastewater and unreasonable use of pesticides and fertilizers is increasing rapidly, resulting in major threat to the environment and contaminate soils. Silicon (Si) is the second most abundant element in the earth crust after oxygen. Although it's higher accumulation in plants, yet Si has not been listed as essential nutrient however, considered as beneficial element for growth of plants particularly in stressed environment. Research to date has demonstrated that silicon helps the plants to alleviate the various biotic and abiotic stresses. This review article presents a comprehensive update about Si and heavy metals, minerals and salinity stresses, and contained the progress about Si so far done worldwide in the light of previous studies to evaluate the ecological importance of Si. Moreover, this review will also be helpful to understand the Si uptake ability and its benefits on plants grown under stressed environment. Further research needs for Si-mediated mitigation of heavy metals and mineral nutrients stresses are also discussed. (C) 2016 Elsevier Ltd. All rights reserved.

Nitrogen fertilizer leaching from cropped and irrigated sandy soil in Central Turkey Ünlü, Kahraman; Yurteri, C (Wiley, 1999-12-01) Pollution of ground water caused by excessive and uncontrolled use of nitrogen fertilizer is worrying. A recent example of such pollution has been observed in an agricultural basin in the province of Nevsehir, Turkey, where up to 900 kg ha(-1) nitrogen fertilizer is used for growing potatoes in sandy soils under irrigation. Using nitrogen fertilizer in amounts that guarantee large yields without polluting ground water is essential. We present results of field experiments and numerical simulations involving ...
Catalytic ozonation of synthetic wastewaters containing three different dyes in a fluidized bed reactor Balcı, Ayşe İrem; Özbelge, Ayşe Tülay; Department of Chemical Engineering (2011) Environmental regulations have imposed limitations on a wide variety of organic and inorganic pollutants in industrial textile wastewaters. There are several degradation methods used in literature studies. Among these methods ozonation is one of the most considered way to degrade refractory chemicals in textile wastewaters. In recent years, catalytic ozonation as being one of the advanced oxidation processes (AOPs), is applied to reduce the ozone consumption and to increase the Chemical Oxygen Demand (COD) ...
Inorganic Cadmium Detection Using a Fluorescent Whole-Cell Bacterial Bioreporter Elcin, Evrim; Öktem, Hüseyin Avni (Informa UK Limited, 2020-11-01) Cadmium pollution has become a serious environmental issue due to its toxicity and frequent entrance into environment components such as soil, water, and air via many anthropogenic sources. Over the last two decades, whole-cell bacterial bioreporters have been acknowledged as bio-sentinels for the determination of toxic heavy metals. Herein a sensitive and quite specific bacterial bioreporter was developed to cope with the need for the rapid and simple determination of cadmium. The construction and characte...
Modelling of nitrogen removal in Ankara wastewater treatment plant Kim, Eun-Ah; Gökçay, Celal F.; Department of Environmental Engineering (2002) Nowadays environmental legislations in many countries have all imposed strict effluent quality standards for carbon, nitrogen and phosphorous for wastewater treatment plants. This in turn caused complicated design, operation and control of biological treatment systems. As a result, computer programs based on complex mathematical models are now developed for the simulation of such complicated systems. The influent wastewater characterization based on COD and Nitrogen fractionation became very important in de...
Ambient VOC concentrations in the city of Balikesir and its environment Yalçın, Giyasettin Efdal; Tuncel, Süleyman Gürdal; Department of Environmental Engineering (2013) The assessment of volatile organic compounds (VOCs) has become an important field of interest in atmospheric pollution. This study quantifies and characterizes the ambient levels and spatial distribution of VOCs in urban and rural areas of Balıkesir. In addition, for the city drinking water dam excess flux from the traffic estimation was done. For these assessments passive sampling of VOCs performed at approximately 50 locations in and around the city of Balıkesir and analyzed with GC-FID system. Tenax TA w...
