Remediation in this study employs the use of green plants and their extracts enhancing remediation process polluted soils. GC-MS & FTIR techniques were employed determining constituents soil during investigation. 60 ml applied on 1 by 2 ft segments hydrocarbon site observed for two months. The results show that plant extract A significantly reduced TPHs PAHs to 5,450 126.2 mg/kg, respectively, ...
Total petroleum hydrocarbons (TPHs) is one of the most important environmental challenges. Phytoremediation of oil-polluted soil depends on microorganisms of the rhizosphere. This study attempts to evaluate the microbial impact of Zea mays rhizosphere during a 60 day period using three different treatments: control soil, oil-polluted soil and oil-polluted soil including fertilizer (NH4No3, K2HP...
مشکلات زیست محیطی متعددی در نتیجه توسعه بی رویه شهر تهران ایجاد شده است. از مهم ترین آن ها می توان به وجود تاسیسات نفتی در آبخوان جنوب تهران ، عدم رعایت معیارهای زیست محیطی از سوی شرکت های نفتی مربوطه و وضعیت نامناسب فاضلاب های شهری و صنعتی منطقه نام برد. هدف از این مطالعه بررسی آلودگی نفتی آبخوان زیر پالایشگاه نفت تهران می باشد. منطقه مورد مطالعه با مساحت 900 هکتار شامل بخشی از آبخوان اصلی دشت...
abstract petroleum pollution is one of the most common and dangerous pollutions that is due to petroleum industries such as refineries, and consequently of oil pipes and tanks leak causing environmental pollutions. one of the newest born technologies in this area is phytoremediation, in which plants are used for decreasing of petroleum pollution. this technology is used for remediation of soil,...
Biopiling is an ex situ bioremediation technology that has been extensively used for remediating a wide range of petrochemical contaminants in soils. Biopiling involves the assembling of contaminated soils into piles and stimulating the biodegrading activity of microbial populations by creating near optimum growth conditions. Phytoremediation is another very successful bioremediation technique ...
Ecklonia cava (EC) is a natural material commonly used to decrease swelling, allergy, cancer, and sleep issues. Using EC has been reported regulate hormones during ovarian failure in an aromatase inhibition rodent model. The aim of this study was investigate EC’s benefits on ovariectomized female mice. Hormone replacement therapy beneficial menopause, but the risk side effects increases. In pre...
Biogenic iron oxide nanoparticles synthesized from a locally sourced, readily available plant — Azadirachta indica, were used synergistically with sodium persulphate (PS) to degrade total petroleum hydrocarbons (TPHs) in contaminated soil. A chemometric approach optimizing the conditions for degradation of TPH was developed using central composite design (CCD). Characterization carried out X-ra...
هیدروکربن های نفتی (tphs) از جمله گازوئیل، جزء آلاینده های معمول خاک بوده که می توانند حاوی ترکیبات سمی باشند. زیست پالایی روشی پذیرفته شده برای پاکسازی خاک های آغشته به ترکیبات نفتی می باشد که یکی از انواع آن، گیاه پالایی است. نکته مهم برای موفقیت آمیز بودن پالایش خاک های آلوده به ترکیبات نفتی با روش گیاه پالایی، انتخاب گیاهان مناسب با قابلیت رشد و سازگار شدن با محیط آلوده است. جنس festuca، گی...
introductionpersian gulf is a water body at the margin of indian ocean which makes way to oman sea and indian oceanthrough the strait of hormuz with the minimum width of 56 km. specific condition of the persian gulf such ashigh evaporation, high salinity, aqueous species diversity, fisheries value and especially oil sources of the area,which have extra importance in the world, have made it a se...
