Wasit Governorate is characterized by industrials activities such as groups of asphalts and bricks factories, oil fields and thermal power plant, in addition to the agricultural activity that is widely separated, which leads to pollution of the surface soils with heavy metals. The main objective in this research is to assess heavy metals pollution and understand the distribution in the surface soils in the studied area. Twenty two surface soils samples were collected from 6 districts and 4 subdistricts within Wasit Governorate during April 2017. The results obtained showed that grain size analyzes are classified as sandy mud (sand 9.5%, silt 50.8 % and clays 39.8%). In the term of geochemical parameters, high level of soil salinity in Wasit Governorate was in Badrah station (8%). Organic matter records 3.7% as a relative maximum concentration in industrial soils at 7.2 pH. Heavy metals Mo, Cu, Pb, Zn, Ni, Co, Mn, As, Cd,V, Cr, Br, Ta, Zr, Ba and Sr were investigated in the soils samples in Wasit Governorate. Assessment of heavy metal pollution has calculated by using the index of geo-accumulation (I-geo), Contamination factor (CF), pollution load index (PLI) and I-geo has been commonly applied as a degree of pollution in soils samples. The pollution load index (PLI) characterizes the number of times in which the heavy metal concentrations of sediment exceeds the background concentration; it provides a cumulative indication of the overall level of heavy metal toxicity in a certain sample. By using these statistical indexes of soils, the results show that soils samples in the studied area are very polluted by the heavy metals of Titanium (72.7 ppm), Nickel (188.9) to considerable with Molybdenum (9.85 ppm), Chromium (226 ppm), Cadmium (2.2ppm), bromine (27.ppm) and Strontium (431.6 ppm), and with moderate pollution of the heavy metals of Copper (54.7) Cobalt (13.4 ppm), Manganese (781.8ppm), Vanadium (104.3ppm) and zinc (117.6ppm
A biological experiment was conducted in the field of Biology Department-College of Education (Ibn Al-Haitham) University of Baghdad for growing season of (2004-2005), to study the effect of two varieties of the fenugreek plant (Trigonella foenum – graeccum L.) and gibberellic acid concentration (0, 25, 50, 100, 125) part per million and duration of four spraying (15, 20, 25, 30) day determining concentration medicinal active saponine compounds like (Trigonelline, choline, Carpaine and Gentianine). The experiment was performed according to complete Randomize Complete Blocks Design (RBCD) by three replicate was adopted, means were compared by using the least significant difference at (0.05) probability level. Results showed t

These piles are suitable for many soils with problems such as softening clay, the variation of groundwater table, expansive soils, black cotton soil, and loose sand. The current study reviewed the behavior of belled piles in multi-layer soils subjected to axial compression and pullout loading. The review covered the experimental and theoretical works on belled piles in multi-layered soils. These piles were subjected to static and dynamic loadings in compression and pullout cases. Most theoretical results focused on software such as PLAXIS 3D. The axial load applied on the piles comes from the upper

Various methods have been used to minimise this effect, such as replacing the gypseous soil or using soil stabilisation (grouting or soil improvement). This study was carried out on four types of gypseous soils that have different properties and various gypsum contents. The testing was carried out on remoulded samples to evaluate the compressibility of gypseous soil under different conditions. The samples were grouted with acrylate liquid. The relationships between the injection pressure and the radius of flow, between time of injection and radius of flow, and between time and quantity of acrylate liquid are investigated on

With the aim of preserving the environment and reducing the damagse as aresult of the negative effects of the activities of these units.
The researh deal with two sides the first one identifies the theoretical framework of the concept of environmental audits, requirements, methods, types of procedures, and duties of the auditor in conducting environmental audits. It also deals with the concept of the enviro

Basra province is known for its logistic location for trading activity and oil industry. By geological point of view, Basra areas are believed to consist mainly of alternation of (clay, silty clay, clayey silt, silt and sand) type of soil. Any development of industry in this area should be affected by the occurrence of the clay soil. That is why the investigation to the soil is more than necessary. In this case, a vast testing program was carried out by the author to evaluate the various formations constituting the of some Basra soils. An attempt to characterize and discuss the nature, minerals, engineering behavior and field properties of soil samples extracted from more than one thousand and one

Show MoreThis paper presents the finite strain results from seven oriented samples data on Tertiary sandstone of Muqdadiya Formation and (400) samples of pebbles and conglomerate of Bai –Hassan Formation at the southwestern limb of Al-Tib Anticline in the Southeastern part of Iraq. Measurement and analysis of finite strain are carried out including these rocks at fluvio- lacustrine environment. The present study followed Fry method. The computed strain was, in the form of ellipses, within three prepared perpendicular planes in a single sample and Center to Center method was used to determine the strain ratio of the these samples. The strain in the studied area is low, this is mainly due to the sampled rocks underwent brittle deformation d

It is designed for two aims, the first is to demonstrate the seasonal variations in physicochemical parameters of Tharthar-Tigris Canal and Tigris River; the second is to explain the possible effects of canal on some environmental properties in the Tigris River. Water samples were being collected monthly. Six sampling sites were selected, two on Tharthar Canal and four along the Tigris River, one before the confluence as a control site and the others downstream the confluence with the canal. For a period from January to December 2020, nineteen physicochemical parameters were investigated including air and water temperature, turbidity, electrical cond

The difficulties of examining the roads whether they are appropriate or not for transporting wind turbine components. The selected site for establishing wind farm is located at Maysan province and has 262 km distance from Um – Qaser port. The results through applying remote sensing and GIS techniques on Landsat (30 m resolution) and QuckBird (0.6 m resolution) are summarized by (2 hard turn, 18 Bridges that crossing over, and 13 Bridges passing under).
