“…Thorough biological methods treat soil contamination through bioremediation mechanism, which is a rapidly-developing way for restoration of natural processes in the environment (5). Common biological soil treatment methods are phytoremediation (12,15), land farming (16,17), SVE (18), bioventing (19), natural attenuation (20,21), biopile (22), and bioreactor (13,23). The cheapest method is natural attenuation, but mostly requires the longest time for the treatment process and is not effective on most of the PAHs.…”

Background: Crude oil contamination is one of the major concerns for the human health and environment. Objectives: The aim of this study was to find the optimal biological methods to remove crude oil contaminants, especially polycyclic aromatic hydrocarbons (PAHs), from the soil of the lands around the Tehran Refinery site. Materials and Methods: In this study, soil sampling was conducted from five points of the west side of the refinery area through a zigzag sampling method. The soil characteristics were identified in the soil laboratory where PAH contamination was also examined. Advantages and disadvantages of biological, physical, and thermochemical methods of soil treatment were retrieved from the literature. The biological methods were confirmed as the optimum treatment methods which had been more extensively evaluated according to the soil texture, remediated compounds, cost, and timing. Results: The soil was largely composed of silt and clay (silt:41-42%, clay: 40-43%, sand: 15-18%). The average moisture content of the saturated soil was 12.96%,; average electricity conductivity was 18.64 DSm-1 ; average pH of the paste was 8.36; and average percentage of organic carbon was 0.19%. Result of the laboratory analysis reported the average content of total nitrogen as 0.026%, phosphorus as 14.3 mg/kg-1 and potassium content as 3.4 mg/kg-1. Content of the crude oil derivatives was less than 0.5 %. Conclusions: An efficient method for treating the current low level soil contamination around the Tehran Refinery site is phytoremediation, a cost effective method that helps to create beautiful landscapes around the refinery site. Soil vapor extraction (SVE) should be used in large PAH levels (higher than the current rate). Soil washing is the most time-effective method, which is suitable for cases of emergency soil contamination with petroleum.

“…Similarly, in a field trial, Paudyn et al ( 2008 ) reported >80 % contaminant (diesel) removal by aeration using rototilling approach at remote Canadian Arctic location over a 3-year study period; this further demonstrates that in land farming technique, aeration plays crucial role in pollutant removal especially at cold regions. Land farming is usually used for remediation of hydrocarbon-polluted sites including polyaromatic hydrocarbons (Silva-Castro et al 2012 ; Cerqueira et al 2014 ); as a result, biodegradation and volatilization (weathering) are the two remediation mechanisms involved in pollutant removal. Land farming system complies with government regulations, and can be used in any climate and location (Besaltatpour et al 2011 ).…”

Environmental pollution has been on the rise in the past few decades owing to increased human activities on energy reservoirs, unsafe agricultural practices and rapid industrialization. Amongst the pollutants that are of environmental and public health concerns due to their toxicities are: heavy metals, nuclear wastes, pesticides, green house gases, and hydrocarbons. Remediation of polluted sites using microbial process (bioremediation) has proven effective and reliable due to its eco-friendly features. Bioremediation can either be carried out ex situ or in situ, depending on several factors, which include but not limited to cost, site characteristics, type and concentration of pollutants. Generally, ex situ techniques apparently are more expensive compared to in situ techniques as a result of additional cost attributable to excavation. However, cost of on-site installation of equipment, and inability to effectively visualize and control the subsurface of polluted sites are of major concerns when carrying out in situ bioremediation. Therefore, choosing appropriate bioremediation technique, which will effectively reduce pollutant concentrations to an innocuous state, is crucial for a successful bioremediation project. Furthermore, the two major approaches to enhance bioremediation are biostimulation and bioaugmentation provided that environmental factors, which determine the success of bioremediation, are maintained at optimal range. This review provides more insight into the two major bioremediation techniques, their principles, advantages, limitations and prospects.

“…Successful alternative that overcomes the problem of quick dilution and wash out of watersoluble nutrients containing nitrogen and phosphorus is oleophilic biostimulants. The application of N and P sources in oleophilic form is considered to be the most effective nutrient application method, since oleophilic additives remain dissolved in the oil phase and thus are available at the oil-water or oil-sediment interface where they enhance bacterial growth and metabolism [43,51].…”

Petroleum pollution has become a serious environmental problem, which can cause harmful damage to the environment and human health. This pollutant is introduced into the environment from both natural and anthropogenic sources. Various physicochemical and biological treatments were developed for the cleanup of contaminated environments. However, bioremediation is based on the metabolic capabilities of microorganisms, and it is considered as the most basic and reliable way to eliminate contaminants, particularly petroleum and its recalcitrant compounds. It is more effective alternative comparing to classical remediation techniques. A high diversity of potential hydrocarbon degrader's microorganisms was reported, and bacteria constitute the most abundant group, which has been well studied for hydrocarbon degradation. Several bioremediation approaches through bioaugmentation or/and biostimulation have been successfully applied. The interest on the optimizing of different parameters to achieve successful bioremediation technologies has been increased. In this chapter, we summarize the diversity and the hydrocarbon degradation potential of microorganism involved in the remediation of contaminated environments. We also present an overview of the efficient bioremediation strategies used for the decontamination of polluted marine environments.
