sara sharifi hoseini Ahmad Landi Saied Hojati Neemat JaafarzadehBackground and Objective: Soils and waters are frequently subject to contamination by inorganic elements including As, Cd, Cr, Cu, Hg, Mn, Ni, Pb, and Zn, mainly due to anthropogenic activities, such as mining, incineration of wastes, drilling of petroleum shaft and agr MoreBackground and Objective: Soils and waters are frequently subject to contamination by inorganic elements including As, Cd, Cr, Cu, Hg, Mn, Ni, Pb, and Zn, mainly due to anthropogenic activities, such as mining, incineration of wastes, drilling of petroleum shaft and agricultural practices (i.e., pesticides and sewage sludge application). Phytoremediation employs the use of plants to degrade, remediate and stabilize various environmental contaminants in soil, water and air. Biochar (BC) can be produced from a wide range of organic wastes via pyrolysis. It has great potential as an amendment for phytoremediation but its effects depend on the type of feedstock it derives from. This study was conducted to identify the effects of biochar addition and phytoremediation on As, Cr, and Pb concentrations in a soils polluted by oil drilling wastes.Material and Methodology: The current study was carried out to examine the heavy metal immobilizing effect of biochar produced from sugar cane waste and subsequent heavy metal uptake by Sorghum, Atriplex sp. and prosopis farcta. Sugar cane wastage biochar was incorporated into four application rates (0, 0.5, 1 and 2 % (w/w)) and soil biochar mixtures were examined for an incubation period of 2 months (so that the contaminated material could be distributed evenly in the soil particles). Then pot trials were provided for cultivation of Sorghum, Atriplex sp and Prosopis farcta so that for each plant, a row of 12 pots and a total of 36 pots for the three under-study plants.Findings: The results showed, average of Cr, As and pb concentration in contaminated soil is 56, 53.4 and 582 ppm. Average of Cr, As and pb concentration in contaminated soil is Amendment with BC is 30, 21.5 and 224. Average of Cr, As and pb concentration in contaminated soil is Amendment with Sorghum is 22, 7.2 and 43, Amendment with Atriplex sp is 16, 15.3 and 141, Amendment with prosopis farcta is 18, 19.9 and 192 ppm.Discussion and Conclusion: Effective treatment of Cr was prosopis farcta and 1 % (w/w) biochar, Sorghum and 2 % (w/w) biochar for As and pb. Although heavy metal-contaminated soils can be reclaimed effectively by application of biochar, further research is needed to explore its long-term environmental and economic aspect to gain maximum benefits from this novel material Manuscript profile -

Contamination has increased with the expansion of exploration and production activities, which has imposed enormous environmental challenges to the drilling industry. This study has been carried out to determine the concentration of nickel and cadmium in a drilling cutting dump site in Azadegan plain in Khuzestan province. Method: Soil samples were obtained from 13 sampling points in drill cutting dump site in Azadegan Plain, Khuzestan province to investigate soil pollution with nickel and cadmium. A-1 was selected as a background station. The rest of 12 stations were named as sample points (B2-M13) and 2 samples were obtained for each station in order to determine the concentrations of heavy metals in different depths. In this study, the Simple Random Cluster Sampling and Stratification Sampling methods were used in an area of 100*100 m2. After preparation, samples were analyzed by atomic absorption spectroscopy. Findings: The results showed that the concentration of cadmium in the soil varied from trace amount to 3.1 mg/kg, which was below the standard limit. Moreover, the concentration of nickel varied from 0.08 to 200 mg/kg. According to the results, the concentrations of heavy metals were lower than the toxicity limits for heavy metals in natural soil. Also there was no significant deviation from EPA, WHO standards and Europe action level for soil. Nickel concentration is negligible in all surface samples. Cadmium concentrations in all samples were below the standard limits. Nickel concentration was found to be over the threshold only in two sample points in depth of 40 cm. Nickel concentrations in K-11 and H-8 were 172 mg/kg and 200 mg/kg respectively. Although there is no sever environmental concerns related to these heavy metals in dumping site, land spreading was suggested as the best alternative for managing the area. Discussion and Conclusions: After performing the experiments, no significant environmental concerns associated with heavy metals was seen. However, land spreading method was chosen as the best method for environmental management in the area Manuscript profile -

Optimization of drilling fluid properties leads to reduce drilling time and costs. Water-based drilling mud is one type of drilling fluid that is mainly used in drilling wells due to its environmental compatibility. In this research, in order to increase the efficiency of this type of drilling fluid, graphene and silicon oxide nanoparticles in equal weight ratio in water-based drilling mud have been used. This study investigates the effect of different concentrations (0.25, 0.5, 0.75 and 1% volume fraction) of these nanoparticles on different properties of drilling fluid such as plastic viscosity, yield point, gel strength of 10 minutes and 10 seconds, circulation loss of the samples and the coefficient of thermal conductivity are discussed. All rheological properties tests are performed according to the standard (API RP 13B). The transient hot wire method has been used to determine the thermal conductivity of the fluid. The results show that the increase of nanoparticles has a significant effect on the rheological and thermo-physical properties of water-based drilling mud and reduces plastic viscosity (15%), decreases circulation loss of the samples (25%) and gel strength and also increases the thermal conductivity by 16% in the volume fraction of 1%.

The samples of the tunnel fresh excavated soils, of the accumulated soils, and of the natural soils in disposal area were taken, randomly. All the samples were sieved and to determine the percentage of drilling foam material, organic carbon percentage of some of them were analised. Elevation and geographic location of the sampling sites were also determined. the directions and speeds of strong winds that have blown in the east of Isfahan was obtained and ranked. Comparison of the granulometry analysis results of the mentioned soils showed that there are great differences between the mentioned criteria of the freshly excavated soils with natural soils and there are afew diffrences between the mentioned criteria of the accumulated soils with natural soils. These differences increase the permeability in the region and reduce the balance between the morphogenic-pedogenic processes.The topographic findings show that mainly accumulating soils in the region have somehow changed the topography of the area that will cause disruption the balance between the morphogenic and pedogenic processes and increase morphogenic processes. Also, the strong winds don't blow toward Isfahan, consequently the environmental hazards will not be created Manuscript profile -
