Background and Objective: Studying the extent of change and destruction in resources in previous can contribute to efficient planning and utilization of these resources and limiting similar adverse changes in the future. Since changes in resources occur over large expanses of land, remote sensing technology can serve as a essential and valuable tool for monitoring these changes. The purpose of this study was to monitor the land cover changes in Qaresu watershed in Ardabil province using the remote sensing technique. Methods: In this study land cover changes was consulted in 30 years from 1985 to 2015. Landsat images of the study area pertaining to July 1985, 2000 and 2015 were acquired. After geometric and elevation corrections, the images were classified by the supervised approach using the maximum likelihood method. The NDVI index, DEM, and slope layers were used to enhance the image classification accuracy. Classification accuracy was assessed with Kappa index and overall accuracy indexes. Findings: The results showed 20.43% change in the watershed’s land uses over the period from 1985 to 2000, 41.426% over the period from 2000 to 2015, and 27.99% over the period from 1985 to 2015. In all three periods, the greatest changes were in dry farming. Discussion and Conclusion: Results showed despite high capability of Landsat images in mapping land use, using additional layers like NDVI, elevation and slope percent can improve separation accuracy of land using.

Background and Objective: Due to high mobility and toxicity of mercury in environment and also high accumulation of mercury in food chain, it is important to understand and predict human exposure and ecological risk assessment of mercury. The purpose of this study was to investigate the total concentration of mercury and it's bioavailabilty in sediment of Petrochemical and Ja'fari creeks. Method: In the present study, 27 sediment samples were collected from the sampling sites. Digestion was employed in sample digestion followed by analysis using MOOPAM. samples were analyzed and determined for mercury concentrations by Mercury Analyzer model VM-3000 MERCURY VAPOR MONITOR. Sediments were further investigated for mercury fractions using a three step sequential extraction procedure of BCR. Findings: The concentrations of THg in sediment samples with a minimum of 2.19 and maximum of 45.71 and average of 23.9 milligram per liter show that area is contaminated with mercury according to the National Oceanographic and Atmospheric Administration standard. Discussion and Conclusion: The sequential extraction procedure showed that most Hg in the sediments was largely bound un exchanable phases. Therefore it can not be exchanged between water and sediment under the physicochemical conditions with alkaline pH. The mercury which bound to exchanagble phase can easily desorb and adsorb by sediments. High content of mercury was in station close to chloralkaline factory and with distance, Hg concentration was decreased.

Background and Objective: The present study was carried out in order to investigate the influence of citizenship education on social responsibility, social skills and environmental skills of Bojnord municipal employees. Method: This study is practical quasi-experimental pre-test post-test type with a control group. The statistical population includes all the 810 municipal employees of Bojnord, from which 60 employees were chosen using simple random sampling. The chosen employees were divided into two 30-member groups. One group was control and the other was considered the test group. The pre-test was administered for both groups. After holding 12 sessions of citizenship education for the test group, the post-test was administered for both groups. Matsun social skills questionnaires (1983), Emam Goli environmental behavior (2012), Five NEO personality traits of responsibility subscale (1985) were used for data collection. The validity of questionnaires was of face and content validity, which was approved by professors. The validity of Matsun social skills questionnaires (1983), Emam Goli environmental behavior (2012), Five NEO personality traits of responsibility subscale (1985) was 0.859, 0.899, and 0.821, respectively. Descriptive statistics (frequency distribution table, mean, standard deviation), inferential statistics (the investigation of data normality via Kolmogrov-Smirnov, covariance analysis, t-test), SPSS 22 and PLS 3 were used for data analysis. Findings: Factor analysis results revealed that citizenship education influences social responsibility, social skills and environmental skills 25%, 39% and 79%, respectively. Hence, it can be claimed that citizenship education has had a positive meaningful influence on social responsibility, social skills and environmental skills of Bojnord municipal employees. Discus s ion and Conclusion: According to the results of factor analysis in the post-test phase on the experimental group, citizenship education had the greatest impact on responsibility. Therefore, as citizenship education increases, employees' responsibility for the two components (social and environmental skills) is more affected and improved.

Background and objective: High concentration of elements (particularly heavy elements) have been always associated with environmental problems in terms of threats for local animals and plants, making it necessary to determine the concentration of heavy elements when assessing environmental quality. Geogenically high concentration of heavy elements and their spread across protected zones tend to impose irreparable damages to regional environment. Method: In the present research, remote sensing studies based on ETM and ASTER data were undertaken to determine regional alterations and structures, and geochemical studies were performed to determine how and why environmentally heavy elements are spread across Palang-Darreh region and Dali deposit located in Markazi province, with the results finally compiled into an environmental interpretation. Approximately, a total of 471 samples were processed، of which 62 samples were taken from Palang-Darreh area. The samples taken from Palang-Darreh area were analyzed via ICP and ICP-OES methods. Findings: Once finished with processing and statistically analyzing the chemical data، elemental anomaly diagrams and maps were prepared and, finally, statistical populations were investigated with respect to the international criteria set by WHO (World Health Organization). Discussion and Conclusion: It was indicated that, high concentration of some elements across the area was of geogenic nature. Since this location is a protected area and Dali mine is situated here, so survey of medical geology studies and proper solutions were presented to lower human and environmental of locations.
