a research project was designed to compare the level of accumulated mercury in common and silver carp muscle tissues from sanandaj gheshlagh dam. these fish were the most consumed fish in the region. during july to december 2009, forty eight samples of these species were randomly caught (24 samples each). total mercury in muscle tissues was measured by advanced mercury analyzer (model, leco 254...
Basaltic lavas have been reported at the base of the Shemshak Formation in some areas of the Alborz zone. However, detail observations of geological outcrops in different areas in eastern Alborz show that these rocks in most aereas around Shahrood (e.g. Gheshlagh in Khosh Yeilagh area) and Damghan (e.g. Tazare, Talo and Kalate Rodbar) are intrusive as sill, dike and small stocks and in few area...
Background and Objectives: Due to the importance of Sanandaj Gheshlagh Reservoir (SGR) in the region and proven mercury pollution in SGR water, a research project was carried out to determine the amount of mercury concentration and bioaccumulation and its behavior through a food route in SGR food chain (i.e., water, sediments, fish, and human).This was done, because it has been reported that me...
rangelands are among the natural resources which have a considerable effect on environment and man’s life. iranian rangelands mostly have poor condition and exhausted by intensive over grazing, should be utilized according to their ecological capability and land suitability. the main objective of this study is to evaluate ecological capability and land suitability of gheshlagh dam’s watershed a...
The Olang area is a part of Gheshlagh-Olang synclinal, which is a member of eastern Alborz coal basin and is situated at a distance of70 km northeast of Shahroud city. Coal-bearing strata of this region are part of the Shemshak group (Upper Triassic to Lower Jurassic).Samples from the 9 coal seams of the Olang coal deposits were collected and ashed. The aim of this study is to determine theoccu...

In natural resources, economic evaluation is poor in terms of study due to the uncertainty of non-consuming value of resources. In the present study, the evaluation of water, soil and plant resources in watershed management projects and expert questioning was done to enable the projects to be evaluated and prioritized economically. Three sub-watersheds were selected from the Parcel A ...
The current research was conducted in 2021 in 5 stations in order to investigate the quality of water before the operation of Javeh Dam in Kurdistan Province. Sampling of fish and Macrobenthos was done using an electrofishing device and Surber sampler, respectively. A total of 13 fish species were identified, which belonged to 3 families: Cyprinidae, Mastacembelidae and Nemachielidae. Out of th...
introduction several valuable calcite deposits are located in ghare-gheshlagh, south basin of urmia lake, nw iran. ghare-gheshlagh area is situated in the northern part of tectono-sedimentary unit, forming nw part of tertiary sanandaj-sirjan geological belt (stocklin and nabavi, 1972). the predominant rock types of the area include light color limestones (qom formation) and quaternary alluviums...
The levels of four different heavy metals [cadmium (Cd), lead (Pb), chromium (Cr) and copper (Cu)] were determined in various vegetables [leek (Allium ampeloprasum), sweet basil (Ocimum basilicum), parsley (Petroselinum crispum), garden cress (Lepidium sativum) and tarragon (Artemisia dracunculus)] cultivated around Sanandaj City. The contributions of the vegetables to the daily intake of heavy...
