This study addresses the issue of the danger of the high amount of Nitrates and Nitrites found in Cucumbers grown in greenhouses in the coastal region in Tartous - Syria, one hundred samples of greenhouse Cucumbers (in their green state) were collected at random from 50 Greenhouses in ten villages in Sahil Akkar in Tartous the villages are: (Arzona, Madihli, A. Zibdi, B. Shofan, Shas, Riyaf, Zahid, Dkaiki, Habroun and T. Sunoun) five Greenhouses were selected from each village, a special information card was prepared for each greenhouse which included the area of the greenhouse, the type of fertilizers used in it, and the source of water used to irrigate the house, the water was tested by a device known as Colorimeter, another device called Spectrophotometer was used to test the amount of Nitrates and Nitrites found in Cucumbers, the results show that the highest amount of Nitrates was in the samples taken from Riyaf 615.29 mg/kg, and the lowest amount in the samples from T.Sunoun 126.15 mg/kg, The Nitrites were at their highest also in Riyaf at 0.06 mg/kg and at their lowest in the samples of B, Shoufan at 0.023 mg/kg, the results also show variation in the Probability value (P=0.000) in the Cucumbers samples. When comparing the amounts reported by the World Health Organization (WHO) it was found that the amounts of Nitrates and Nitrites ranged between 100% in Riyaf, A. Zibdi and Madhli, followed by 90% in B.Shoufan, and 80% in Habroun and Dkaiki,and 60% in Arzona, Zahid, and Shas ,and 30% in T. Sunoun. The percentage of contamination in all the Greenhouses reached only 76%whole. the concentration of the Nitrites was within the standard level less than 1%mg/kg.

Research summary
تتناول هذه الدراسة خطورة زيادة تركيز النترات والنتريت في الخيار المنتج في البيوت البلاستيكية في محافظة طرطوس، سوريا. تم جمع 100 عينة خيار من 50 بيت بلاستيكي في عشر قرى مختلفة في منطقة سهل عكار. تم تحليل العينات باستخدام أجهزة Colorimeter وSpectrophotometer لتحديد تركيز النترات والنتريت. أظهرت النتائج أن أعلى تركيز للنترات كان في قرية الرياف (615.29 ملغ/كغ) وأقل تركيز في تل السنون (126.15 ملغ/كغ). بالنسبة للنتريت، كان أعلى تركيز في الرياف (0.06 ملغ/كغ) وأقل تركيز في بيت شوفان (0.023 ملغ/كغ). عند مقارنة النتائج مع الحد المسموح به حسب منظمة الصحة العالمية، كانت نسبة العينات الملوثة بالنترات في قرى الرياف والمدخلة وعين الزبدة 100%، بينما كانت نسبة التلوث العامة في كل العينات 76%. كانت تراكيز النتريت ضمن الحد المسموح به في جميع العينات. توصي الدراسة بضرورة مراقبة نوعية المنتجات الزراعية وتحديد استراتيجيات للحد من التلوث بالنترات والنتريت لضمان جودة المنتجات الزراعية وصحة الإنسان.
Critical review
دراسة نقدية: تعتبر هذه الدراسة مهمة جداً في تسليط الضوء على مشكلة التلوث بالنترات والنتريت في المنتجات الزراعية، خاصة في منطقة تعتمد بشكل كبير على الزراعة المحمية. ومع ذلك، كان من الممكن أن تكون الدراسة أكثر شمولية إذا تضمنت تحليلاً للآثار الصحية المباشرة على السكان المحليين، بالإضافة إلى دراسة تأثيرات التلوث على المدى الطويل. كما أن الدراسة لم تتناول بشكل كافٍ تأثيرات العوامل المناخية والموسمية على تراكيز النترات والنتريت. من الجيد أن الدراسة قدمت توصيات عملية، لكن كان من الممكن أن تكون أكثر تفصيلاً وتحديداً في كيفية تنفيذ هذه التوصيات على أرض الواقع.

In this research, the natural pyrite ore found in Tartous Governorate was described by studying the two samples taken from Hosn Suleiman -Safita (A) and Al Qadmous (B) area, in addition to studying the optimum conditions for pyrite dissolution (pH - time - quantity) with aerobic conditions. The results of X-ray diffraction (XRD) showed that the sample (A) is mainly composed of pyrite mineral and does not contain impurities, while sample (B) is composed of pyrite mineral combined with a small amount of calcite mineral, and these results were confirmed by the result of (FTIR) infrared spectroscopy and Polarised light microscopy (PLM(. The iron percentage in the two samples (A,B) is ranged between (42.6 – 43 %) and the sulfur percentage is between (40 – 53.7 %). With regard to pyrite dissolution, the results showed that pyrite taken from Hosn Suleiman (A) begins to dissolve at pH values less than 4.5, and the contact time is about 6 hours. By Comparing the results of sample (A) with sample (B), we found that the dissolution of sample (A) was about three times less than the dissolution of sample (B), and this is due to the fact that sample (A) contains pure and well crystallized pyrite ore while sample (B) contains pyrite combind with calcite, which increases its solubility.
The problem of drinking water scarcity exacerbates in some villages in Tartous governorate making water conservation a priority. The aim of this study is to identify the patterns and practices of household water consumption of a sample of water su bscribers in Tartous governorate in order to determine the procedures through which to rationalize the consumption of drinking water. For this purpose, a survey of 150 household water subscribers was conducted. The answers were then subjected to a statistical analysis. The results indicated the presence of a high percentage of those who follow the procedures for rationalizing the consumption of water within the sample (95.3%), and a low percentage of those who have the techniques for reducing water consumption (4.7%). The majority of those surveyed (87.3%) objected to increasing the price of water as a measure to reducing water consumption. The study revealed that there is a good aqueous awareness in the governorate on which one can rely in rationalizing the consumption of drinking water through awareness campaigns.
Organizations face significant challenges affecting their performance, especially as they operate in an unstable environment. This study aims to investigate the effect of market orientation on organization‘s performance, through a survey covering Syriatel and MTN Centers in Tartous Governorate. This study's data have been collected through a questionnaire designed to measure market orientation and environmental variables. The SPSS program is used for obtaining results. This research shows a positive relationship between market orientation and environmental variables and the organization’s performance in general. The value of the correlation coefficient between the independent variables and the dependent variables is 73%, and the coefficient of determination is 53.2% when the degree of confidence is 95%. This study also shows that technological turbulence, as a component of environmental variables, has a negative effect on organization‘s performance, whereas both intelligence generation and market troubles have a positive effect on organization‘s performance.
The research was conducted in plastic green house for the 2013-2014, in Alqangerh village, about 5 Km from the city of latakia, in order to study the effect of spraying the leaves with some humic compounds and amino acids on growth and production o f hybrids of cucumber (Novo,Dorruk). Spraying leaves with three organic fertilizers are (Huzone, Mol mixs), and two boats Dbalin and Amino vega (an amino acid). The results showed that all treatments of leaves spraying with organic fertilizer geve better resultus with significant differences than the control treatment in all the studied traits of both hybrids: (stem length, number of branches/plant, number of leaves/plant, leave area cm2, the number of flowers on the stem, number of fruits on the stem, number of floral branches, number of fruits on the branches).The treatment of spraying achieved with mixture of humic compounds and amino acids increase with significant differences in both the number of leaves/plant, number of branches/plant, the plant's stem length and number of fruit on the stem in the hybrid Novo. while the treatment of spraying achieved of hiozon increase with significant differences the number of branches/plant, the number flowers on the branches and number of fruits on the branches was in the hybrid Dorok. As for the early production and total production, the treatment of spraying with mixture of humic compounds and amino acids with significant differences on other transaction when both hybrids Novo and Dorruk amounted, respectivety (5 ، 4,1 kg/m2 ; 16 ، 14,8 kg/m2 ).
A study of effectiveness of methyle bromide (MB) and two of its alternatives were carried out to evaluate their impact on soil sterilization, the density of nematode and on the growth and production of carnation crop. The experement was carried ou t in two plastic houses of 400m2 in Zabadani region during 1999-2000.The treatments were as follows; MB(28g/m2), metam sodium (75cm3/m2), soil steaming and control. The results showed significant-differences between the control and the treatments, where the effectiveness of reducing the density of nematodes were 55.6%, 53.4%, 69.9% and 0% respectively. The soil steaming treatment encouraged the plant vigour and harvest started earlier, but the average number of carnation flowers for the different treatments were 28.3, 23.9, 32.8 and 23.8 (flowers during each harvest day) respectively. Confirmed differences were found for yield, where the highest number of carnation flowers were found in the plots treated with metam sodium, and therefor we recommend using metam sodium as a part of integrated pest management program of nematodes in carnation cultivatar.
