In this work, a new electrokinetic remediation technology was used to remove heavy metal and hydrocarbon from contaminated soil. The surfactant combined with PASP (Polyaspartic acid) enhance removing Electric current, soil pH, electroosmotic flow, water content variation, removal efficiency residual distribution, speciation, of TPH (total petroleum hydrocarbons), group composition oil, mechanis...
به منظور بررسی میزان هیدروکربن های آلیفاتیک در خوریات ماهشهر، پنج ایستگاه به نام های بندر امام خمینی، خور جعفری، خور احمدی، خور زنگی و خور غنام انتخاب گردید و نمونه برداری از آب و رسوبات در هر ایستگاه انجام شد.نمونه های آب در بطری های شیشه ای تیره و نمونه های رسوب درون فویل آلومینیوم جمع آوری وپس از انتقال به آزمایشگاه ، محتوای هیدروکربن های آلیفاتیک آن توسط حلال های آلی هضم و استخراج گردید. ن...
This study was carried out to assess the human health risk associated with a crude oil spill site in Emohua Local Government Area of Rivers State, Niger Delta. The Total Content and Fraction’s approaches were adopted risk. approach by comparing concentration various contaminants environmental media studied Intervention Values prescribed while Fractions using RBCA Toolkit for Chemical Releases v...
Genes that encode for enzymes that can degrade petroleum hydrocarbons (PHs) are critical for the ability of microorganisms to bioremediate soils contaminated with PHs. Distributions of two petroleum-degrading genes AlkB and Nah in soils collected from three zones of the Dagang Oilfield, Tianjin, China were investigated. Numbers of copies of AlkB ranged between 9.1 × 10(5) and 1.9 × 10(7) copies...
Barrier islands of Northwest Florida were heavily oiled during the Deepwater Horizon spill, but less is known about the impacts to the shorelines of the associated estuaries. Shoreline sediment oiling was investigated at 18 sites within the Pensacola Bay, Florida system prior to impact, during peak oiling, and post-wellhead capping. Only two locations closest to the Gulf of Mexico had elevated ...
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, ...
Were evaluated natural attenuation, biostimulation and bioaugmentation on the degradation of total petroleum hydrocarbons (TPH) in soils contaminated with diesel oil. Bioaugmentation showed the greatest degradation in the light (C12 C23) fractions (72.7%) and heavy (C23 C40) fractions of TPH (75.2%) and natural attenuation was more effective than biostimulation. The greatest dehydrogenase activ...
BACKGROUND Due to the high concentrations of total petroleum hydrocarbons (TPH) in oily sludge and their environmental hazards, the concern regarding their effects on health and the environment has increased. The main objective of this research was focused on evaluating the feasibility of using Fenton process in removing TPH in oily sludge from Shiraz oil refinery, Southern Iran. RESULTS To d...
Background and purpose: Toxicity, high levels and complex nature of petroleum hydrocarbons in drill cutting can endanger human health since many of these compounds are among carcinogenic hazardous waste components. This study aimed at comparing the effect of compost and vermincompost processes in removing petroleum hydrocarbons from drill cutting located in Ahvaz oil field with sewage sludge. ...
