The concentration of dissolved organic carbon (DOG) and the specific ultraviolet absorbance (SUVA) of peat, soil, and water samples collected from the Zoige wetlands on the eastern Tibetan Plateau in August 2008 were determined. The DOC concentration was 36.34 +/- 15.27 mg L-1, falling in the range of the DOC concentration in wetlands of other regions. However, the mean SUVA of the DOC was 0.55 +/- 0.33 L mg(-1) m(-1), showed a comparatively low aromaticity among wetlands. Significant variations of DOC concentration and their SUVA were both found under different spatial scales. The results showed that both the concentration and aromaticity of the DOC are influenced by the water table in the peatland. The significant difference of the DOC concentration among the three types of wetland showed the influence of plant growth on the DOC in the soils, and the SUVA indicated the different sources of the DOC in the different wetlands. The results also indicated that the DOC concentrations in stream water are consistent to the proportion of peatlands in the corresponding catchment.
测定了2008年8月在青藏高原东部若尔盖湿地采集的泥炭、土壤和水样的溶解有机碳(DOG)浓度和比紫外吸收(SUVA)。DOC浓度为36.34 +/- 15.27 mg L-1，落在其他地区湿地的DOC浓度范围内。而DOC的平均SUVA为0.55 +/- 0.33 L mg(-1) m(-1)，芳香性在湿地中相对较低。不同空间尺度下，DOC浓度及其SUVA均存在显著差异。结果表明，泥炭地土壤中DOC的浓度和芳香性均受地下水位的影响。三种湿地间DOC浓度的显著差异表明植物生长对土壤DOC的影响，SUVA表明不同湿地中DOC的来源不同。结果还表明，河流中DOC浓度与相应集水区泥炭地比例一致。

Imazamox, is a herbicide intensively used in the peanut field soils of Osmaniye, Turkey with Mediterranean climate conditions. In this study, two types of soils were selected, first not exposed (NE) to Imazamox previously and the second Imazamox treated peanut soil (P). The recommended field dose [(RFD), 40 g L -1 active ingredient], 2 × RFD, and 4 × RFD of this herbicide were added to the NE and P soil. The microbial activities of the soils were measured by carbon and nitrogen mineralization under two different humidity conditions [60% and 80% of field capacity (FC)]. Carbon mineralization was determined by the CO 2 respiration method at 30°C over 45 days. Mineralization ratios (%) of carbon in all herbicide doses of P humidified at 60% and 80% FC were significantly higher than all the other dose–humidity combinations of NE soils (P<0.001). Despite the NH4-N, there were significant differences between the NO3-N contents of these two soils (P≤0.05). These results showed that nitrate producing bacteria were still very sensitive to foreign compounds added to the soils. These results suggest that soil microorganisms consumed the Imazamox as C and/or N sources without being effected by different humidity conditions.
Imazamox是一种除草剂，主要用于地中海气候条件下土耳其Osmaniye花生田土壤。本研究选择未接触Imazamox的土壤(NE)和处理过Imazamox的花生土壤(P)两种类型的土壤，分别在NE和P土壤中添加该除草剂的推荐田间剂量[RFD]， 40 g L -1有效成分]，2倍RFD和4倍RFD。采用碳氮矿化法测定了两种不同湿度条件下(60%和80%田间容量条件下)土壤微生物活性。碳矿化用co2呼吸法测定，温度为30℃，时间为45天。60%和80% FC加湿的磷在所有除草剂剂量下的碳矿化率(%)显著高于其他所有东北土壤剂量湿度组合(P<0.001)。除NH4-N外，两种土壤NO3-N含量差异显著(P≤0.05)。这些结果表明，产生硝酸盐的细菌对添加到土壤中的外来化合物仍然非常敏感。这些结果表明，土壤微生物在不受不同湿度条件影响的情况下，作为C和/或N源消耗了Imazamox。

Litter is an important component of organic matter replenishment. Rhododendron ponticum L. is an important understory deciduous shrub species of Fagus orientalis Lipsky Forests in the Western Black Sea region. The goal of this study is to determine the effects of altitude and slope on deciduous litter traits. The relationships between litter and soil traits were also investigated with the help of numerical methods. We found that litter and soil traits were significantly changed along the elevational gradient. We also found that C (carbon) and N (nitrogen) concentrations and the C/N ratio of R. ponticum litter were lower than that of other Rhododendron species. The C/N ratios were lower at 400 m, while gradually increasing along the elevational

In this study, the possible oxidative stress that water pollution may cause to Asellus aquaticus is evaluated using the physico-chemical parameters, the heavy metal concentration in the water, and organism and biochemical responses in the living organisms being combined together. For this purpose, the A. aquaticus samples are collected by choosing three stations along the Saricay Creek, some of whose regions are exposed to domestic and industrial pollution. Sampling stations are chosen from regions that are interpreted as polluted or clean according to the heavy metal content and physico-chemical parameters where the A. aquaticus individuals live. After the determination of species is performed, the heavy metal (Cu, Fe, Cd, Pb, and Zn) and biomarker (Na+/K+-ATPase, Glutathione, and TBARS) analyzes were made. According to the water quality analysis, S3 was the most polluted station, S2 was a moderately polluted station, and S1 was determined as a clean station. A considerable increase in the amount of glutathione (GSH) was detected in the S2 and S3 stations in parallel with the increase of pollution. However, there were no statistical differences in the TBARS levels as an indicator of lipid peroxidation and Na + /K + -ATPase enzyme activity. The significant increase (three-fold) of the GSH levels in the polluted areas indicates that water pollution causes oxidative stress in the A. aquaticus species. These results show that ecological, physico-chemical, and biochemical parameters can be used together to identify and evaluate the water pollution in rivers that are

This study investigated the characteristics and dyeing fastness of chrome-tanned bovine leathers. Chitosan formate was applied to the leathers in four different proportions. The dye exhaustion and tensile strength of the leathers increased as the proportion of chitosan formate increased, and the highest levels of both dye exhaustion and tensile strength were obtained in an application at a proportion of 200% solution containing 2.5% chitosan on the basis of leather weight. In addition, chitosan formate was found to improve the pollution parameters of dyeing effluents such as chemical oxygen demand, total suspended solids, total dissolved solids, salinity, and electrical conductivity.

This study was conducted to determine the concentration of boron in the waters of the Gediz River. According to the results, the boron concentrations ranged from 0.125 to 4.548 mg/L. The average boron value (2.428 mg/L) was compared with “Environmental Regulations, Water Pollution Control Regulations and Quality Criteria for Inland Water Resources by Class”. The Gediz River was determined as class IV (very polluted) in terms of the boron parameters. It was concluded that the reason for the high boron values were natural and/or industrial discharges at some stations.

The spatio-temporal variation of the phytoplankton community structure and the environmental factors that affect its distribution and the changes in Homa Lagoon were examined. Sampling took place monthly at four stations between December 2006 and December 2007. During the study period, a total of 58 taxa of which 52 were used as active taxa in the numerical analysis (relative abundance>1%) were from four algal classes, Cyanophyceae, Dinophyceae, Bacillariophyceae, and Euglenophyceae. In general, the most important groups were diatoms and dinoflagellates in terms of species numbers and abundance. The mean Shannon-Weaver’s diversity index (H') and Pielou evenness index (J') values were 2.35 and 0.83, respectively. An abundance of the bloom of certain phytoplankton species, especially Cylindrotheca closterium and Navicula sp., was thought to be the cause of the low diversity index and evenness values. Although nitrogen was thought to be limiting in temperate regions, phosphorus was a limiting factor on the phytoplankton growth in the Homa Lagoon because of the correlation between the abundance and N/P ratio. The relationship between the phytoplankton communities and 10 environmental variables were researched using a canonical correspondence analysis (CCA). According to the Monte Carlo unrestricted permutation test, the temperature and nitrate concentration were the most important variables in accounting for species distribution.

Noise pollution is among the most prominent environmental problems encountered in every aspect of daily life. The effect of noise pollution is the cause of a variety of serious health hazards. Special care should be taken to prevent noise pollution especially in areas which are sensitive to noise such as hospitals, parks, and educational institutions. One such area is the university campus; however, very little research has been conducted on this subject. In the present study, noise levels were measured on the Ataturk University campus in Erzurum, Turkey. Results of the study revealed that the average noise level was 62.70 dB(A) exceeding 55 dB(A), which is an average permitted value. A map was created to indicate the noise levels throughout the campus. This map is available for use as a reference in the planning phases of new universities. Noise mitigation should be considered in the planning phases of new university campuses.

This study was carried out under Ordu ecological conditions in an unheated plastic tunnel type greenhouse between 2008-2009 production seasons. In this study, the effect of growth medium of natural hazelnut husk compost enriched with organic fertilizer at different ratio on cultivation of garden cress was researched. Organic fertilizer was added to hazelnut husk compost (adjusted to by volume 5%, 10%, 15% and 20%) in the manner that nitrogen would be 1%, 2%, 3% and 4% by using the nitrogen content of growth medium as a base. Natural hazelnut husk was accepted as a control application. In the study which was coordinated as a pot trial, each pot was examined as a replication and the study was carried out according to randomized parcels base design with three replications. In the study, seed plantings (2 g/m2) were made in two different seasons; spring and autumn. Autumn planting was made in 10 September 2008 and spring planting was made in 28 April 2009. Plants were harvested two times for each two seasons. After harvest was finished, plant yield, leaf width, leaf length, vitamin C and leaf color (chroma, hue) values were determined. In the study, organic fertilizer applications statistically increased yield and leaf quality. In terms of yield value, 2% N application with 2052 g/m 2 gave the highest yield. Yield and leaf width values were higher in the first harvests. All fertilizer applications increased garden cress width and length. Amount of vitamin C increased 80% according to the control in 2% N application. Fertilizer addition created more green leaves on plants. Usage of organic fertilizer added natural hazelnut husk in the cultivation of garden cress is important in terms of both plant yield and quality improvement, and environmental sustainability.
{"title":"Lepidium sativum Cultivation in Organic Fertilizer Added Hazelnut Husk Compost","authors":"Gulnur Karaal, A.

In this study, the effect of growth medium of natural hazelnut husk compost enriched with organic fertilizer at different ratio on cultivation of garden cress was researched. Organic fertilizer was added to hazelnut husk compost (adjusted to by volume 5%, 10%, 15% and 20%) in the manner that nitrogen would be 1%, 2%, 3% and 4% by using the nitrogen content of growth medium as a base. Natural hazelnut husk was accepted as a control application. In the study which was coordinated as a pot trial, each pot was examined as a replication and the study was carried out according to randomized parcels base design with three replications. In the study, seed plantings (2 g/m2) were made in two different seasons; spring and autumn. Autumn planting was made in 10 September 2008 and spring planting was made in 28 April 2009. Plants were harvested two times for each two seasons. After harvest was finished, plant yield, leaf width, leaf length, vitamin C and leaf color (chroma, hue) values were determined. In the study, organic fertilizer applications statistically increased yield and leaf quality. In terms of yield value, 2% N application with 2052 g/m 2 gave the highest yield. Yield and leaf width values were higher in the first harvests. All fertilizer applications increased garden cress width and length.
