Aim: To study the total oil and grease (TOGs) removal potential of three abundant herb species of crude oil contaminated sites, namely Xanthium strumarium (L.), Ageratum conyzoides (L.) and Polygonum hydropiper (L.) from oil contaminated soils. Methodology: The pot experiment was carried out by taking soil samples of crude oil contaminated agricultural field. For each experimental plant, three replicas were maintained and a similar control setup was maintained without plants for comparing the results. Another control set up was maintained in non-contaminated soils to compare the plant growth p

The ameliorative potential of maize husk on crude oil impacted soil had been documented. The aim of this study was to evaluate the effect of maize husk treatment of crude oil contaminated soil on morphological and biochemical indices of cowpea seedlings. Treatment of soil with maize husk significantly (p< 0.05) increased the morphological and biochemical indices comparable to control seedlings. On the other hand, exposure of cowpea seedlings to crude oil-contaminated soil caused significant (p< 0.05) decreases in both morphological and biochemical indices compare to values in control see

Abstract:

Phytoremediation is an economic and environmentally friendly method for the remediation of hazardous crude oil contaminated soils. In this study, phytoremediation of crude oil contaminated soils by elephant grass (pennisetum purpureum) was investigated over a 40-day period. Grass clumps were harvested and transplanted into plastic buckets filled with 1kg of soil contaminated with 30 ml and 40 ml of crude oil and an uncontaminated control sample. An additional control sample was contaminated with 30 ml of crude oil with no elephant grass. The samples were analyzed periodically for changes in pH

Atterberg limit tests were preformed on diesel oil contaminated soil and crude oil contaminated soil. The results show that Atterberg limits reduced with increasing of diesel oil content. When crude oil content changed from 0 to 8%, it has little effect on Atterberg limits. However, it rose from 8% to 16%, plastic limit slightly decreased, but liquid limit increased remarkably. A "pseudo-viscosity" caused by crude oil is the key factor for this phenomenon.

Abstract:

In recent years, one of the primary issues noted worldwide in the environment is the contamination of crude oil in soil. In comparison to traditional methods, bioremediation offers a potential alternative for removing hydrocarbon pollution from the environment. This review paper gives an overview of the benefits, mechanism, and operation of aerobic composting remediation of soil contaminated with crude oil. Within this study, it was demonstrated that with composting technology, one could successfully treat crude oil contaminated soil with a > 90% removal efficiency. Aerobic composting utili

This paper considered the toxicity assessment of some crude oil contaminated soils in Niger Delta areas. The soil samples were collected from different horizontal distances, vertical depths and contaminated soil of different ages. The heavy metals in the contaminated soils were digested and extracted using di-acid digested and DTPA extraction methods respectively. The physiochemical parameters (moisture content, pH, N, P and heavy metals (Ni, Pb and Cd) were analysed with APHA method. The heavy metals concentration was determined using atomic absorption spectrophotometer (AAS). The results sho

Abstract:

The contamination of crude oil in soil matrices is a persistent problem with negative repercussions because of the recalcitrant, hazardous, and mutagenic properties of its constituents. To mitigate the effect of crude oil contamination in soil, the use of microorganisms is a cheap and feasible option. In the current study, bacterial species from numerous polluted oil field surfaces were isolated and examined for their ability to degrade crude oil. Random soil samples polluted with hydrocarbons were collected and various bacterial isolates were isolated. Results revealed that 40% of total isola

When crude oil is spilled on the soil, an oil film is formed, which prevents air from penetrating into the soil. Oil pollution changes the physicochemical properties of the soil, and also affects its temperature, structure, nutrient content and pH, while soil pollution with various organic substances, metals and, in particular, heavy metals is typical. The paper substantiates the use of remediation procedures in the sense of complex optimization, which provides for parallel processing of various soil types.
