Book excerpt: The purpose of this experiment was to determine the effect of soil loading rate on the microbial performance during active phase co-composting of diesel-fuel contaminated clay soil under simulated windrow composting conditions. Microbial performance was monitored through relative heat generation, volatile solids destruction, and headspace oxygen/methane levels. Additional analyses in the form of radio-labelled diesel fuel, which was monitored through NaOH traps for respired 14CO2, and total petroleum hydrocarbon (TPH) concentrations were attempted during the experimental run. A total of seventeen biocells were used during the experiment. Soil loadings ranged from 0% contaminated soil to 30% contaminated soil. Each biocell received the same amount of compost amendments, with altering soil loadings. Biocells were placed in an environmental chamber for a duration of two weeks. During that time, the chamber temperature was ramped to simulate temperatures within a compost heap. Biocell height and temperature readings were taken at least three times daily. Air was supplied to the biocells for five minutes every hour, and the offgas from the biocells was bubbled through NaOH traps to capture respired CO2 and 14CO2. (Abstract shortened by UMI.).

Book excerpt: Contaminated Soils offers state-of-the-art technologies for detection and remediation of diesel contaminated soils that can be used by environmental professionals to maximize the practical application of theory. The book covers all aspects of assessment of soils contaminated by diesel fuel and discusses the most successful remediation techniques currently available. These techniques include the use of hydrocarbon analyses for environmental assessment and remediation, physical and biological treatments, and vent walls for enhancing biodegradation of contaminated soils. The development of a monoclonal antibody immunoassay for detecting gasoline and diesel fuel in the environment and a comparison of the purge and trap procedure versus the extraction procedure for detecting kerosene and diesel fuel No. 2 are examined as well. The book concludes with a chapter discussing human health-based soil cleanup guidelines for diesel fuel No. 2. Contaminated Soils is a must for professionals concerned with the quality of groundwater and hazardous waste cleanup, regulators, oil company officials, and libraries. Features:

Available in PDF, EPUB and Kindle. Book excerpt: Studies have found that under constant environmental conditions, the rate of biodegradation of petroleum hydrocarbons decreases with time and may become negligible after a period. This decrease in the availability of hydrocarbons for biodegradation can be attributed to the diffusion of the hydrocarbons into soil micropores, the partitioning of the hydrocarbons into soil organic matter, strong surface adsorption or a combination of these processes. Studies have also shown that naturally occurring freeze-thaw cycles act to disrupt soil aggregates to physically change the soil's structure. This study investigated the effects of freeze-thaw cycles on the biodegradation rates of hydrocarbon contaminated soils. A diesel fuel contaminated soil was bioremediated in bench-scale reactors until respiration monitoring indicated a decrease in microbial activity. Designated reactors were then subject to 1, 3, 6 and 9 freeze-thaw cycles. The results indicated an increase in the microbial activity in the freeze-thaw treated reactors, while the microbial activity in the control reactors decreased over the same period of time. The results also indicated that microbial activity increased with increasing numbers of freeze-thaw cycles.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to determine effect of temperature on bioremediation of a diesel fuel contaminated heavy clay soil under simulated landfarming conditions. The Arrhenius temperature coefficient, $\theta, $ was determined to quantify the effect of temperature on biodegradation rate. Biodegradation was measured in soil microcosms by monitoring headspace oxygen concentration and $\sp{14}$CO$\sb2$ evolution from the mineralization of $\sp{14}$C-octadecane. Zero-order biodegradation rates, calculated from oxygen consumption on a tetradecane (n-C$\sb{14})$ equivalent basis, were found to range from 0.13 mg $\rm kg\sp{-1}day\sp{-1}$ at 3$\sp\circ$C to 9.8 mg $\rm kg\sp{-1}day\sp{-1}$ at 22$\sp\circ$C (on a dry weight basis). The average temperature coefficient was 1.19 for the biodegradation rates based on oxygen consumption and 1.11 for the biodegradation rates based on $\sp{14}$CO$\sb2$ evolution. The diesel range n-alkanes remaining in the soil (active and abiotic samples) at the end of the experiment were analyzed by gas chromatography (GC/FID) and compared to fresh unweathered standards to determine the effect of temperature on the final hydrocarbon depletion. The direct measurement of total extractable hydrocarbons at the end of the experiment was not possible since the integration program was not set up to only integrate the n-alkane peaks.

Download or read book Digestate Valorization for Bioremediation of Hydrocarbons Contaminated Soils written by Anna Gielnik and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Petroleum contaminated soils constitute an environmental problem which may be solved with the help of bioremediation. Soil bioaugmentation with petroleum degrading bacteria is an efficient clean-up strategy. Currently scientific interest is focused on sources of bacteria able to degrade hydrocarbons which serve as species pools for enrichments during inoculum preparation. Bioaugmentation treatments are especially important in soils with low level of organic matter and low bacterial counts (e.g. after intensive chemical treatments). Digestate is an organic by-product of biogas production via anaerobic digestion processes and has a great potential as soil fertilizer due to concentrated nutrients. However, the potential of microbial community of digestate was never studied in terms of hydrocarbons degradation. In this thesis, we examined digestate as microbial seeding for bioremediation of weathered petroleum hydrocarbon contaminated soils. Our goals were : i) to check the presence of diesel degrading bacteria in digestate enrichments and compare diesel degradation potential with enrichments from petroleum contaminated soils, ii) verify the effect of digestate application on soil microbial community and microbial activity, iii) study the presence of functional genes responsible for hydrocarbons degradation (alkB genes) in digestate and amended soils. During the first experiment, seven microbial enrichments were developed from various digestates, petroleum contaminated soil and from mix of soil with digestate. After 3 weeks of incubation the highest diesel oil removal was observed for enrichments originating from composted digestate and from petroleum contaminated soil (78 and 77 % diesel oil removal, respectively). Enrichments obtained from digestate mixed with soil have lower performance than single source enrichments. In all enrichments, presence of alkB genes was promoted during the incubation.In a second experiment, 6 different treatments were performed in microcosm using two industrial petroleum contaminated soils having different textures: a clay rich soil and a sandy soil. After 30 days of incubation, the highest petroleum hydrocarbons removal was observed in microcosms containing: digestate together with bulking agent (17.8 % and 12.7 % higher than control in clay rich soil and sandy soil, respectively) or; digestate together with immobilized bacteria (13.4 % and 9 % higher than control in clay rich soil and sandy soil, respectively). Distinct microbial groups were formed in amended and non-amended soils. Genera containing species able to degrade hydrocarbons like Acinetobacter and Mycobacterium were abundant in digestate and soil amended with digestate. High concentration of alkB genes were found in digestate, after soil application, the level of alkB genes significantly increased in soils and remained high during one month of treatment. In a third experiment, a contaminated soil was incubated with digestate and bulking agent in bioreactors with active aeration. Initial alkB concentration was 1.5 % in contaminated soil and 4.5 % in digestate. During incubation of soil with digestate, alkB percentage increased up to 11.5 % and after additional inoculation with immobilized bacteria this value increased up to 60 % (alkB percentage for treatment with mineral nutrients reached 0.4 %). Addition of digestate positively affected soil respiration and bacterial density, which was concomitant with enhanced hydrocarbons degradation. Incubation of soil with digestate for 2 months resulted in 74 % of hydrocarbons removal, while extra addition of immobilized bacteria increased this value to 95 %. Digestate increased soil bacterial density and diversity of hydrocarbons degrading taxa.Results obtained during this thesis confirms that digestate is a good source of hydrocarbon degrading bacteria and reveals its great potential to increase abundance of alkB genes responsible for hydrocarbon degradation in soils during bioremediation.

This book was released on 2018-04-30 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document presents key messages and the state-of-the-art of soil pollution, its implications on food safety and human health. It aims to set the basis for further discussion during the forthcoming Global Symposium on Soil Pollution (GSOP18), to be held at FAO HQ from May 2nd to 4th 2018. The publication has been reviewed by the Intergovernmental Technical Panel on Soil (ITPS) and contributing authors. It addresses scientific evidences on soil pollution and highlights the need to assess the extent of soil pollution globally in order to achieve food safety and sustainable development. This is linked to FAO’s strategic objectives, especially SO1, SO2, SO4 and SO5 because of the crucial role of soils to ensure effective nutrient cycling to produce nutritious and safe food, reduce atmospheric CO2 and N2O concentrations and thus mitigate climate change, develop sustainable soil management practices that enhance agricultural resilience to extreme climate events by reducing soil degradation processes. This document will be a reference material for those interested in learning more about sources and effects of soil pollution.
