1. ASSESSMENT OF ELECTROMAGNETIC FIELDS AROUND SELECTED ELECTRICAL SECONDARY TRANSFORMERS AND ITS EFFECT ON THE ATTACHED HOUSES IN KUWAIT

Authors: A. ELUMALAI , E. AL-BASSAM

Abstract: This paper presents a detailed description of the work performed on the assessment of electromagnetic fields (EMF) levels around three electrical secondary transformers (substations) installed in a residential area for one year. The EMF measurements were taken during fall, winter, spring, and summer seasons. In addition, the magnetic field measurements for houses that are attached to the substations were taken during summer in August between 10:30 am and 14:00 pm, using EMDEX II and SNAP meters. The results have shown that no electric field is generated in the vicinity of the substations (underground lines), which is considered an advantage compared to overhead lines, whereas, the magnetic field levels were detected. The measurements of the magnetic field were directly proportional to the electrical consumption, either daily or seasonally. Moreover, the magnetic field levels inside the attached houses were above the value of 0.4 μT due to cable lines, electrical panel, wiring circuits,

2. POLYCYCLIC AROMATIC HYDROCARBONS (PAHS) ON SIZE SEGREGATED PARTICLE PHASE IN URBAN ATMOSPHERE, ISTANBUL

Authors: AIGERIM KISTAUBAYEVA , ARSLAN SARAL , GULSUM SUMMAK, , HATICE COLTU , S. LEVENT KUZ

Abstract: Polycyclic aromatic hydrocarbons (PAHs) are semi-volatile organic compounds and present widely in ambient atmosphere. Due to the fact that PAHs are widely distributed in the environment and some species of them are carcinogenic, they are very important for human health and environment. High volume cascade impactor was used to collect the particulate matters according to particle size fractions between February 2013 and June 2014, in Istanbul. Particulate matters were collected according to size ranges >7.2 μm, 7.2 - 3 μm, 3 - 1.5 μm, 1.5 - 0.95 μm, 0.95 - 0.49 μm, <0.49 μm. 15 PAH species were analyzed in samples. Average of total PAH concentrations were found as 31.62 ng/m3. Total PAH size distribution was found between 0.95-1.5 μm. All investigated ring PAH species showed single modal distribution in size range of 0.95-1.5 μm. 4, 5 and 6-ring PAH species have high concentration in almost each size range. According to the obtained results, 4, 5, 6-ring PAHs are abundant on the particl

Authors: OMER FARUK ALGUR , SERKAN ORTUCU

Abstract: In this study, effects of various environmental factors on resistance and susceptibility to mass production against two isolates of Beauveria bassiana species (AT007 and AT076) which show entomopathogenic activity under low humidity levels and low spore concentrations are aimed to compare. In that purpose, growth and sporulation of isolates in different temperatures, and resistance against UV radiation are compared in terms of tendency to mass production. Effect of temperature on colony diameter and sporulation were analyzed under 20C, 25C and 30C. To compare the UV resistance, prepared spore suspensions were spray on SDA medium. Then, the suspensions were exposed to UV (Philips 35 W) for 15, 30 and 60 minutes open cover from 30 cm distance. Tendency to mass production were determined by growing on brazen material which is commonly used in spore production and the ability of spore growth were evaluated. AT007 and AT076 isolates showed much more diameter increase under 25C temperatu

4. ESTRONE-INDUCED BIOCHEMICAL AND MOLECULAR CHANGES CONFERS TOLERANCE TO BORON TOXICITY IN WHEAT SEEDLINGS

Authors: HULYA TURK , MUCIP GENISEL , SERKAN ERDAL

Abstract: To determine the effects of estrone on the ability of plants to tolerate boron toxicity, estrone (0.01 μM) and boron (5 mM H3BO3), singly or in combination, were exogenously applied to 11-d-wheat seedlings and 3 days later from treatments, they were harvested to determine many parameters. Boron toxicity caused to remarkable reductions on the root and shoot lengths. Besides, it led to a marked decrease in the activities of antioxidant enzymes, including superoxide dismutase (SOD), guaiacol peroxidase (GPX), catalase (CAT), ascorbate peroxidase (APX) and glutathione reductase (GR), as well as an decrease in the level of soluble protein and photosynthetic pigments including chlorophyll and carotene. Thus, boron toxicity bring about a significant oxidative injury by increasing levels of the superoxide anion (O2 -.), hydrogen peroxide (H2O2) and malondialdehyde (MDA). Whereas estrone was able to reduce the boron-induced oxidative damage and improved the antioxidant system. Moreover, the eff

Authors: JAE-KYU YANG , JANARDHAN REDDY KODURU , LAKSHMI PRASANNA LINGMADINNE , YOON-YOUNG

Abstract: In order to develop water treatment performance, graphene oxide based inverse spinel nickel ferrites (GONF) and reduced graphene oxide based inverse spinel nickel ferrites (rGONF) nanocomposites were prepared using graphene oxide (GO) and inverse spinel nickel ferrite (NiFe2O4) by thermal precipitation method. The interface interactions of GO and NiFe2O4 were studied. The X-ray diffraction spectrometer (XRD), and Fourier-transform infrared spectroscopy (FT-IR) and BET studies showed that the formation GONF and rGONF. Scanning electron microscopy (SEM) studies observed porous surface morphology of GONF and rGONF. The magnetic studies revealed that the ferromagnetic property of GONF and rGONF, but the later one shows less Ferro magnetic intensity than GONF. It was well performed for the adsorption removal As(V) and subsequently easy magnetic separation from water. The sorption studies revealed that the sorption was rate-limiting pseudo -second-order kinetics with mono layer chimisorption

6. ACACIA CAVEN POLLEN FROM SOUTH AMERICA. AN USEFUL BIO-INDICATOR OF ENVIRONMENTAL POLLUTION. A HEALTHY FOOD SUPPLEMENT?

Authors: CRISTINA BARCIA , DANTE MARTINEZ , SOLEDAD CERUTTI , SONIA BARBERIS

Abstract: The aim of this work is to evaluate the mineral and heavy metal contents of Acacia caven (Mol.) Molina pollen, a South American plant which grows in the Northwest of Argentina, for studying its behavior as bio-indicator of environmental pollution and their consequences as dietary supplement. Mineral and heavy metal contents were determined by flame atomic absorption / emission spectrometry (FAAS and FAES, respectively), inductively coupled plasma optical emission spectrometry (ICP-OES) and hydride generation atomic absorption spectrometry (HG-AAS). The obtained results demonstrated that some mineral contents (K, Ca, P, Fe, Mg, Na, Zn and Se) of Acacia caven pollen met the requirements of both, the Food and Nutritional Board (FNB) and the Argentinean Alimentarius Codex (AAC) to be used as a dietary supplement. Nevertheless, some heavy metals analyzed such as Al, Cu, Ni, V, Cr and Cd, exceeded the upper levels (UL) established by FNB and AAC, probably due to environmental contamination.

7. YIELD CRITERIA IN FABA BEAN (VICIA FABA L.)

Authors: CENGIZ TOKER , NISA ERTOY INCI

Abstract: Most of yield criteria are redundant and breeder spends extra efforts, time and labor to record and evaluate them. Therefore, this study was aimed to elucidate fundamental and redundant yield criteria in faba bean (Vicia faba L.) using correlation, path coefficient and heritability. A total of 109 genotypes of faba bean were sown in autumn at highland of Mediterranean region of Turkey, and grown in two successive years under rainfed conditions. As qualitative traits, rosette-like growth habit and pigmentation during seedling stage were fundamental traits for cold tolerance. Biological yield and harvest index as quantitative traits were found to be the most fundamental traits. As the other fundamental trait, the seed weight could be considered for selection in early breeding generations because they had the highest heritability

8. A BIOSENSORED SPATIAL DATA INFRASTRUCTURE FOR THE DYNAMIC MONITORING OF THE PRESENCE AND THE ACTIVITY OF ENDOCRINE DISRUPTING CHEMICALS IN WATER

Authors: DOMENICO VITO

Abstract: Endocrine disrupting chemicals (EDCs) are a subset of environmental contaminants that can produce adverse developmental, reproductive, neurological, and immune effects in both humans and wildlife. EDCs have been reported to have a ubiquitous presence in the environment and in particular aquatic ecosystems. Many EDCs, in fact are not completely removed with conventional wastewater treatment systems. Due to their harmfulness and ubiquity, since the 1990’s a number of countries, multinational governments such as the European Union and inter-government organizations (Organization for Economic Cooperation and Development, OECD) have initiated or amended programs to integrate EDCs into current strategies to assess chemical safety. These programs has been mainly focused on regulate exposure to EDCs, neglecting the issues about monitoring. Conventional water monitoring processes involves the collection of water samples that only provide snapshots of the situation at the sampling site and time,

9. RESPIRABLE PARTICLE COUNTS AND CONCENTRATIONS IN PUBLIC TRANSPORTATION IN ISTANBUL, TURKEY.

Authors: BURCU ONAT , ULKU ALVER SAHIN

Abstract: This study aims to determine the in-vehicle and outdoor fine particle (PM2.5) concentration and particle number concentration (PNC) for six size ranges (0.3-0.5 μm, >0.5-1.0 μm, >1.0-3.0 μm, >3.0-5.0 μm, >5.0-10 μm, and >10 μm). The measurement campaign was conducted in the morning and evening onboard the Metrobus, red-bus and outdoors. PM2.5 concentration in the Metrobus and red bus were observed as 58.8±10.2 μg/m3 and 76.2±30.9 μg/m3 respectively, and the outdoor value was about 2 times more. For both types of public transportation, the ratio of the amount of internal environment PM and the amount of external environment PM displayed a high level of correlation (redbus/ outdoors, R=0.97; Metrobus/outdoors, R=0.88) with the PM size. The number of commuters, vehicle ventilation type and outdoor air entering the vehicles probably caused the differences in in-vehicle particle concentrations.

10. THE INFLUENCE OF THE AMORPHOUS SIO2 CONTENT ON THE CHARACTERISTICS OF RED-MUD BASED GEOPOLYMERS

Authors: IVANA BOSKOVI , MIRA VUKCEVIC , RADOMIR ZEJAK

Abstract: Curing conditions as well as type and content of silica in raw mixture seem to be very important in both producing quality as well as stability of red-mud-based geopolymers. The influence of amorphous SiO2 along with the other components of raw mixture was studied in this paper. The presence of amorphous silica turned to be a very important factor influencing the strength of red-mud-based geopolymers. The results confirm that the compressive strength of geopolymers increases (up to 41MPa) with the presence of amorphous silica in raw mixture up to the certain point (50 wt %). Excessive content of amorphous silica causes sharp decrease in strength. Microstructure analysis confirms the existence of homogenous structure. The presence of gluing geopolymer phase is also detectable by various techniques.

11. GENO- AND CYTOTOXICOLOGIC ASSESSMENT OF WASTEWATER EFFLUENTS WITH MUSSEL MICRONUCLEUS ASSAY AND WITH FLOW CYTOMETRIC SPERM TOXICITY ASSAY: A COMPARISON.

Authors: BETTINA ECK-VARANK , GABOR PAULOVITS , NORA KOVATS , BALAZS KAKASI , SZABOLCS TAMAS NAGY

Abstract: Several pharmaceutical drugs have potential harmful effect on wildlife such as aquatic toxicity, genotoxicity, or endocrine disruption effect. Removal rates of pharmaceuticals from municipal sewage during waste water treatment is questionable, several studied drugs are insufficiently or not removed while passing through the sewage treatment plants (STP).The analytical monitoring of potentially harmful drugs and especially drug residues in influent and effluent of STP are rather costly and not always possible on a day to day basis. Toxicity bioassays, on the other hand, are relatively cost-effective short-term tests, estimating the aggregate genotoxicity of the samples on different taxonomic levels. In our study the cyto- and genotoxicity of the pre-treated potentially pharmaceutical containing influent and the effluent sample of a Hungarian STP were estimated with mussel (Unio pictorum) micronucleus (MN) assay and flow cytometric boar spermatozoa assay. The influent induced in the flow

12. ASSESSMENT OF MUNICIPAL WASTEWATER GENOTOXICITY USING THE AMES FLUCTUATION TEST, THE SOS CHROMOTEST AND THE MUSSEL MICRONUCLEUS TEST: A COMPARISON

Authors: BETTINA ECK-VARANK , ESZTER HORVATH , GABOR PAULOVITS , NORA KOVATS

Abstract: Municipal wastewaters may contain a variety of genotoxic compounds, including drugs or their metabolites, PAHs, etc. Bacterial genotoxicity assays use DNA impairment as end point while micronucleus tests, conducted on eucaryotes, assess chromosome aberrations. As relatively few comparative studies exist, in this study results of the micronucleus test using the painter’s mussel (Unio pictorum) are compared to those of two bacterial assays, the Ames test and the SOS Chromotest. Both the Ames test and the micronucleus test showed clear concentration-response pattern, however, the Ames test proved more sensitive. Of the two bacterial assays, the SOS Chromotest gave positive result only for the most concentrated sample.

Abstract: The synthesized rGONF was characterized using X-ray diffraction (XRD), Fourier transform-infrared resonance (FT–IR), and X-ray photoelectron (XPS) spectroscopes. The morphology, the surface area and pore volume of GONF was evaluated by scanning electron microscopy (SEM) and BET analysis, respectively. rGONF was successfully used for the removal of U(VI) by batch adsorption techniques. Batch kinetics studies revealed the sorption of U(VI) onto rGONF was well described by pseudo-second-order equation. The sorption equilibrium data of U(VI) was well tune to the Langmuir isotherm model than the Freundlich and Temkin’s isotherm models. Hence, the sorption of U(VI) onto rGONF occurred through monolayer chemisorptions on homogeneous surface of rGONF. The maximum adsorption capacities (Qmax) of the rGONF for U(VI) is 200 mg/g. Thermodynamic studies reveal that the sorption was increased as increase temperature from 298 to 328 K, indicates the chemisorptions. The overall obtained results demons

Abstract: Breast cancer is a worldwide health disquiet and is the second leading cause of cancer death among women. In Oman, it is the most well-known malignancy in women, with an incidence rate of 15.6 per 100,000 of the Omani females. Several anticancer remedies have been found from natural products in the past and the search is continuing to add more examples. Cytotoxic from natural compounds may have a considerable aspect in cancer therapy either in potentiating the impact of chemotherapy or curtailment its harmful effects. As of late, a couple studies have reported the benefit of utilizing crude camel milk as a part of treating a few types of cancer. In any case, no sufficient data are at present accessible on the potential of lyophilised camel's milk for the triggering of apoptosis and oxidative stress linked with human breast cancer.
