“…It is commonly known that the soil contamination with PDSs constitutes a potential danger to human health and life; therefore, in recent years, efforts have been undertaken in order to find effective, inexpensive, and environmentally friendly ways to amend contaminated soils [2][3][4][5]. The most commonly recommended method is biological remediation [6][7][8]. The microorganisms naturally occurring in the environment decompose the contaminants, which removes them from the environment or transforms them into less toxic, or non-toxic and less durable forms in the environment (alcohols, acids, carbon dioxide, and water).…”

Soil Pollution by Petroleum-Derived Substances and its Bioremediation: The Effect on Aphis fabae Scop. Infestation and Antioxidant Response in Vicia faba L.

In this study, the effects of soil contamination with petroleum-derived substances (PDSs) (petrol, diesel fuel and used engine oil) and its bioremediation using biopreparation ZB-01 on broad bean infestation by black bean aphid Aphis fabae Scop., as well as on the antioxidant enzymes activity (superoxide dismutase (SOD), catalase (CAT) and guaiacol peroxidase (POD)) and antioxidant (non-protein thiols and proline) content in plant leaves, were determined. Results showed that after three years from the moment of soil contamination PDSs limited infestation of broad bean by A. fabae. However, the adverse effects on aphids’ life cycles were not proven. The lowered infestation may result from the lower attractiveness of contaminated plants to pests. PDSs significantly affected the activities of enzymes and the antioxidants content, with that effect being diversified. The increased activity of SOD was found in plants exposed to diesel fuel, together with the lowest numbers of aphids accompanying it, which can suggest a certain role of the enzyme in pest response to the stress caused by this PDS. The ZB-01 biopreparation limited the adverse effect of PDSs on the degree of broad bean plant infestation by A. fabae. Its influence on the antioxidant response was diversified. In the plants exposed to EO, changes in antioxidant response were reduced under the influence of ZB-01.

“…In Treatment 1 (bacteria), the reduction of TPH was suggested to be due to the fact that bacteria take the hydrocarbon contaminants as a supplement for population. Bacteria take the hydrocarbon contaminants as source of carbon for new cells constituents and bacteria release enzymes in the soil, which have the ability to catalyze the oxidation of hydrocarbons contaminants [2]- [16].…”

“…Increasing of contamination levels of benzene in soil, will generally increase the duration needed for bioremediation [8]. Using phytoremediation and bioremediation methods for contaminated soil enhance the physical and chemical characteristics of the soil [2], [6], [9]. Plant and bacteria can independently remove hydrocarbon from contaminated soil [9].…”

Abstract-Soil contamination with petroleum hydrocarbons causes many problems for the surrounding environment. The current research aims at studying the performance of different in-situ remediation methods for the removal of total petroleum hydrocarbons (TPH) from sandy soil at different levels of contamination. The remediation methods that were tested include phytoremediation using alfalfa, bioremediation using Pseudomonase putida, and a combination. The soil was spiked with TPH at different levels (2.5%, 5.0% and 10.0%). after 90 days of experiments, the different treatments were able to reduce the level of contamination in the sandy soil with efficiencies up to a maximum of 99.9% for phytoremediation, 98.7% for bioremediation, and 99.0% for the combination method. The experimental results showed that the TPH remediation followed the first-order kinetics.

“…Indeed, on the positive side of the first axis, more than 50% of the variance is explained. The decrease of element concentrations depends on several factors: the decline of the load of water pollutants resulting from self-purification (Bremond and Perrodon 1979), the reduction of floor contamination (bioaccumulation and biodegradation of organic materials), and the frequency of rain which limits the effects of rainfall leaching (Langenbach 2013). Actually, in the dry season, the sampling stations are loaded with organic pollutants.…”

Five-year monitoring of physicochemical parameters was performed with two campaigns in low and high water periods of the Lower Soummam catchment. Data from 18 wells were processed by multivariate statistical tools in order to identify the principal factors influencing groundwater chemistry. Two matrices of 14 and 8 physicochemical parameters with 18 groundwater samples collected in wells were obtained. The correlation matrix showed strong associations between nine variables: K + , Ca 2+ , Na + , SO 4 2− , Cl − , Mg 2+ , NO 2 − , Zn 2+ and Sr 2+. Principal component analysis and factor analysis showed that the cumulated variance of high and low water periods was of 83.19% and 78.55%, respectively. The variables assigned to the mineralization effect or to pollution indicators were presented by the factor analysis. The bivariate plots confirmed a mineralization model, ascribed to dissolution of geological materials, and to high levels of saline contamination attributed to leakages from sanitary systems. They also showed an increase "upstream to downstream" of the mineralization, visualization of temporal variations, and a dilution process identification of the natural mineralization during the recharge of the aquifer.
