- BildiriAçık Erişim2021Control of automatic fire extinguishing operation for 5 forest areas with SCADA
Ustundag, Aybike; Gencer, Cetin
The number of forest fires has increased significantly in recent years. Interventions to forest fires from air and land are very difficult and dangerous. In addition, since these interventions are time-consuming, forest fire can spread to a much wider area. In this study, an automatic fire extinguishing system was designed using SCADA for 5 forest regions up to 5 hectares. In the event of a fire in the system, the smoke sensor in the fire area becomes active and the IP camera image in this area is displayed on the screen. The pressurized water flushing tap, which automatically rotates 360 degrees, works in the area. If desired, automatic operation can be canceled and manually adjusted water flushing tap can be operated. The system gives a warning when the tank water drops below 1 ton. The aim of this study is to automatically intervene early in any fire that may occur in the forest and to control the fire before it spreads.

Topal, Murat
In this study, the bioaccumulation of some metals by Phragmites australis plants exposed to poultry slaughterhouse wastewater was investigated. For this aim, Mo, As, Cd, Se, Cu, Zn, Cr, Ba, Ti, Fe, Al, and Mn metals were determined in slaughterhouse wastewaters, P. australis plants, and sediment samples. The uptake of metals by P. australis was investigated. Also, BCF and TF values were calculated and compared with reference plant values. The maximum metal accumulation in P. australis plants exposed to poultry slaughterhouse wastewaters was 5900% for Al and 33.5% for Mn when compared with reference plant values. According to the BCF values, P. australis was bioaccumulative for Mo, Se, and Al. As a result, it was determined that P. australis plant can be used in the remediation of metals found in poultry slaughterhouse wastewaters and would be a good accumulator.

The lack of ethnoveterinary surveys in Turkey, results in losses in the veterinary phytopharmacology field. This is the first ethnoveterinary research in which statistical calculations about plants are done by informant consensus factor (ICF) method in the Blacksea Region of Turkey. To catalog, analyze, and disseminate the knowledge of plant use in ethnoveterinary practices in the province of Giresun (Turkey). Information was gathered through open and semi-structured interviews with local people, mainly elderly shepherds and farmers, in the Giresun province. The collected data was analyzed quantitatively using two indices, informant consensus factor (ICF). A total of 65 ethnoveterinary plants belonging to 38 families are used for the treatment of animal diseases. According to the local farmers, the most often mentioned species that used in the resarch area have high ethno-veterinary potential. Most of these plants are also used for some human conditions in the study area. There are large numbers of ethno-veterinary practices EVPs in southern Turkey with undocumented cumulative knowledge of the indigenous people. Unfortunately, some evidence of their slow disappearance has been found. The traditional knowledge in the treatment of livestock diseases of the Giresun districts needs further scientific evaluations by phytochemical and antimicrobial experimentation.

Drainage of peatlands increases the depth of the oxic peat layer and can turn them into a carbon (C) source to the atmosphere. Afforestation of drained peatlands could help to reverse this process since the trees may enhance C sequestration. We followed the C and water dynamics of an afforested drained peatland in S-Iceland during a 2 year period, during which the Black Cottonwood (Populus balsamifera ssp. trichocarpa) plantation was 23–25 year old. Net ecosystem exchange (NEE) of carbon dioxide (CO2) was measured with the eddy covariance method and C pools of trees and ground vegetation were measured using the stock change method. Lateral losses of dissolved and particulated organic C (DOC, POC) were estimated from weekly water-runoff samples. Unexpectedly, the afforested drained peatland was a strong sink of carbon during the two years, with an average NEE value of 714 g C m−2 yr−1. Only 0.5% of the total NEE was lost through lateral DOC and POC transport, leaving 710 g C m−2 yr−1 as the total net ecosystem production (NEP). Ca. 91% of the observed NEP could be explained by the annual biomass increment of the Black Cottonwood trees and 1.3% by the ground vegetation. This means that the remaining 7.5% of the total NEP most likely accumulated in peat soil and litter, contributing to the soil C stocks. The dormant-season CO2 emissions were unexpectedly low, which was explained by a high groundwater level at this drained site outside the ca. 5 months of the active growing season. On average, 66% of the annual measured precipitation was estimated to have evaporated back to the atmosphere. This left 416 mm for potential runoff, which was somewhat lower value than the measured runoff (662 mm). These results indicate that during the age span of ca. 20–25 years, afforestation was a valid method to reverse the expected negative C-balance of this drained grassland pasture in Iceland. Although the site is currently a soil C sink, simulation studies with process models are needed to test whether such sites could remain C sinks when managed for forestry over several tree-stand rotations.

Erguven, Gokhan Onder; Demirci, Ulas
To solve the environmental problems of the pesticides, bioremediation methods are commonly useful for their environment friendly properties. These methods are more cheap, useful and have more advantages for remediate receiving environments In this study, imidacloprid which is one of the selective insecticide in all over the world is chosenfor bioremediation studies with two soil bacteria. The imidacloprid used in the Mediterranean climate for cotton, pistachios, tomatoes, peppers and eggplant cultivation. The bioremediation of this insecticide was investigated via the performance of O.thiophenivorans and S. melonis in agitated culture media. The agricultural soil used for the isolation of these two bacteria was taken from the cotton cultivated agricultural area in Adana province in Turkey. For this purpose, the isolated and enriched bacteria were added to the recommended insecticide concentrations, and the Imidacloprid active material, Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD5), Total Organic Carbon (TOC), pH and dissolved oxygen (DO) parameters were determined for two weeks on each day of the study. O. thiophenivorens and S. melonis bioremediate the Imidacloprid insecticide with high efficiency (over 90%). According to these results, it is understood that these bacteria can be preferred in the bioremediation of receiving environments that are contaminated with such pesticides and can be useful for scientists to handle the opposite effects of such persistent organic pollutants and COD, BOD5 and TOC parameters can easily give opinions about decreasing of pesticides like the active materials

Kutlu, Banu; Özcan, Tahir; Özcan, Gülnaz
The ecological risk resulting from the accumulation of some heavy metals in the sediments of Iskenderun Bay was assessed using the following measures: enrichment and contamination factor, pollution load index (PLI), and potential ecological risk index (RI). The concentrations of the studied heavy metals were in the following order: Fe > Ni > Mn > Cr > Zn > Cu > As > Pb > Cd > Hg. Ni and As had the highest EF values. This situation is most likely due to the presence of iron, pesticide, and fertilizer plants in the region. According to the United States Environmental Protection Agency, Ni, As, Mn, and Cr may have harmful effects on faunal communities in sediments. According to the RI, Site 4 was more contaminated and toxic than the other seven study sites, with "moderate"ecological risk. Pearson's correlation coefficient was determined by multivariate methods - cluster and principal component analysis. As can be inferred from the RI values, the potential toxic effect of As and Ni in the sediments is moderate.

The authors regret that the total evapotranspiration shown in Fig. 7 (821 mm) was the measured H2O flux for the whole two year measurement period. The correct average value for the two years was 411 mm yr−1, or 33% of the measured annual average precipitation. This left 827 mm yr−1 as the “estimated runoff” (see corrected figure). The sign of the average NEE values in the Abstract and Conclusions should be negative. All other information is correct, including the equations and interpretations.

Yilmaz, Deniz; Bouarafa, Sofia; Peyneau, Pierre-Emmanuel; Angulo-Jaramillo, Rafael; Lassabatere, Laurent
The increasing global urban sprawl requires large amounts of materials, putting huge pressure on numerous natural resources. In particular, vast quantities of soils are used to create infrastructures or green spaces associated with new developments. Alternative solutions aimed at alleviating soil consumption are thus being encouraged. Creating urban soils by recycling waste from industrial and construction activities is feasible, but apart from their support function the resulting technosols should also be able to provide some ecosystem services such as the capacity to infiltrate water and filter contaminants. Various methods are routinely used for in situ characterization of the hydraulic behaviour of natural soils, but their ability to assess the hydraulic properties of technosols remains unclear. Indeed, technosols formed from recycled waste differ markedly from natural soil because they often contain a considerable proportion of coarse artefacts that affect their structure. In this study, results obtained by two distinct methods (ponding and tension infiltrometry), associated with two data processing methods (Beerkan estimation soil transfer (BEST) and numerical inversion), on a set of infiltration data measured on experimental plots made of technosols have been compared with each other. Both methods provided similar results and thus proved to be reliable when applied to technosols. Highlights: Reuse of by-products from anthropogenic activities is crucial to alleviate the consumption of natural soil. Hydraulic properties of technosols must be monitored to assess some of the ecosystem services they can provide. BEST and numerical inversion of multiple tension disc infiltration data gave consistent results. Reliability of the hydraulic characterization methods used for technosols deserves further inquiry.

Gültekin, Zuhal; Hellmann, Claudia; Aydin, Rahmi; Winkelmann, Carola
The aim of this study was to support the development of ecological stream quality assessment tools in order to provide a method for sustainable water management in Turkey. Therefore, we present two new or adapted indices based on benthic invertebrates. To develop and adapt the indices, 17 streams were studied and separated into three quality classes, which were supported by four community indices (EPT [%], EPTCBO [%], number of Individuals, evenness), and 23 taxa were identified as indicators for these three quality classes. As a first biological index, we adapted the Hindu Kush-Himalaya biotic score (HKHbios) to the Euphrates catchment by establishing a new and ecoregion-specific score list (Euph-Scores) by scoring 93 taxa depending on their distribution between the quality classes. Based on these scores, several average score per taxon values (ASPT value) were calculated. All ASPT values of the Euph-Scores separated the quality classes significantly. After a comparison of the different ASPT values we recommend to use the weighted ASPT, because the weighting enabled a sharper differentiation between the quality classes and named it Euphrates Biotic Score (EUPHbios). As a second biological index, we propose the proportion of habitat specialists. To calculate this index, a habitat score was developed by analysing the habitat preferences of several benthic invertebrates. Habitat score values were assigned to the 20 most common taxa from the streams in the best quality class (natural streams). The proportion of habitat specialists, identified using the new habitat score, differed significantly between the three quality classes, with higher values in natural streams than in polluted streams. In the light of the results, the presented methods appear to be suitable for developing a multi-metric index for assessment programs for the mountainous regions of the Middle East.

Erguven, Gokhan Onder; Yildirim, Numan
Imidacloprid (C9H10ClN5O2) is used as the most recommended type of insecticide in vegetable farming worldwide. Two types of bacteria (Methylobacterium radiotolerans and Microbacterium arthrosphaerae) were isolated from a corn farming field in the Thrace region of Turkey, and then consortia of these bacteria were prepared from equal volumes of 107 CFU/ml for each bacterium type. Imidacloprid remediation studies were carried out during 18 days in soil test units. The water filtered from these soil test units was determined for chemical oxygen demand (COD) and biochemical oxygen demand (BOD5) to determine the optimum concentration of microorganisms to ascertain the best removal efficiency of Imidacloprid. COD removal rates were 98.7%, 96.4% and 51.6% with 80, 40, and 20 ml volumes of the consortia of bacteria, respectively, at the end of 18 days. The BOD5 removal rates were 88.4%, 78.6% and 49.9% in the same volumes of bacteria, respectively. As a result of this study, we have found that this bacterial consortium is very effective for the bioremediation of this insecticide at the two volumes of 40 and 80 ml, both being better than 20 ml.

Çimen, Okay; Öztüfekçi Önal, Ayten; Akyol, Eylem Akarsu
The Hasangazi chromite pit is an abandoned mine located to the east of the town of Pülümür (Tunceli, Turkey). The surface water that circulates in the pit flows into the Pülümür stream via the Turnadere creek. The quality of the surface water and soil from the region is important regarding the ecosystem in the Tunceli area. The open pit operations in the chromite deposits may be the cause of toxic element enrichments. To understand the effects of such pits, samples from the sediments, soil, waste material, and surface water were collected from the Hasangazi pit and its surrounding area. Samples were mineralogically and geochemically analyzed by XRD, ICP-OES, and ICP-MS methods. Mineralogical analyses showed the presence of chrysotile and plagioclase in the sediment and soil samples. These samples are also enriched in toxic elements, e.g., Cr, Ni, and Co. In particular, the Cr and Ni concentrations exceed the limits of soil pollution regulation of Turkey and the US Environmental Protection Agency. Overall the Cr, Ni, and chrysotile contents demonstrate the impact of the abandoned pit and the ultramafic rocks. Moreover, the surface water samples in the dry season have Zn concentrations above the toxic levels that may have been derived from the volcanic rocks. Environmental remediation precautions should immediately be taken around this inactive pit.

The extensive use of pesticides for controlling insects has been widely used in agricultural activities. However, the indiscriminate use of the pesticides has inflicted serious harmful problems to humans in the ecosystem. Our study aims to evaluating the capacity of Armillaria tabescens to remove the chemical oxygen demand (COD) and biochemical oxygen demand (BOD5) at different concentration of malathion insecticide (50, 100 and 150 ppm) under agitated (130 rpm) submerged culture conditions at 27 °C after 8 and 15 days. According to our results, A. tabescens has achieved COD reduction as 52.39, 27.24, and 38.30% at concentration of 50, 100 and 150 ppm respectively on 15 days. The BOD5 reduction rates were found as 78.2, 74.76 and 81.26% at 50, 100 and 150 ppm concentration respectively at the end of the 15th days. At the end of this time period, the dried biomass of A. tabescens was weighted and we have suggested that malathion in medium reduced the biomass production compared the control group (Sabouraud dextrose broth + A. tabescens). Our experiments have focused that; A. tabescens could be an alternative and useful fungus for bioremediation of wastewater containing malathion insecticide.
