TL;DR: Wang et al. as discussed by the authors examined soil bacterial community changes in response to different gradients of salinity and total petroleum hydrocarbon (TPH) concentration, finding that salinity negatively affected soil microbial biomass carbon (MBC) and microbial biomass nitrogen (MBN), but little affected bacterial Shannon and evenness indices.

TL;DR: In this paper, the effect of surfactant on petroleum removal for individual clay mineral types was investigated, and the results showed that the highest petroleum removal rate for a single clay was 13.2 ± 0.98% (chlorite), 34.2± 1.52% (kaolinite), 68.0± 2.84% (montmorillonite), and 86.3± 2% (illite).

TL;DR: In this article, an approach to anode EK was used to decrease the focusing effect during electrokinetic (EK) remediation of chromium-contaminated soils from a chromite ore processing residue (COPR) deposition site.

TL;DR: The results showed that different remediation treatments significantly affected the physicochemical properties, oil contaminant degradation and bacterial community structure of the oil contaminated saline soil.

TL;DR: This integrated system appeared to be a useful option for the treatment of water produced in oilfields using an anaerobic process coupled with micro-electrolysis, focusing on changes in chemical oxygen demand (COD) and biodegradability.
Abstract: Treatment of oilfield produced water was investigated using an anaerobic process coupled with micro-electrolysis (ME), focusing on changes in chemical oxygen demand (COD) and biodegradability. Results showed that COD exhibited an abnormal change in the single anaerobic system in which it increased within the first 168 hr, but then decreased to 222 mg/L after 360 hr. The biological oxygen demand (five-day) (BOD5)/COD ratio of the water increased from 0.05 to 0.15. Hydrocarbons in the wastewater, such as pectin, degraded to small molecules during the hydrolytic acidification process. Comparatively, the effect of ME was also investigated. The COD underwent a slight decrease and the BOD5/COD ratio of the water improved from 0.05 to 0.17 after ME. Removal of COD was 38.3% under the idealized ME conditions (pH 6.0), using iron and active carbon (80 and 40 g/L, respectively). Coupling the anaerobic process with ME accelerated the COD removal ratio (average removal was 53.3%). Gas chromatography/mass spectrometry was used to analyze organic species conversion. This integrated system appeared to be a useful option for the treatment of water produced in oilfields.

TL;DR: This review selectively examines and provides a critical view on the knowledge gaps and limitations in field application strategies, approaches such as composting, electrobioremediation and microbe-assisted phytoremediating, and the use of probes and assays for monitoring and testing the efficacy of bioremediations of polluted sites.
795 citations
TL;DR: The origin, characteristics, and environmental impacts of oily sludge were introduced and no single specific process can be considered as a panacea since each method is associated with different advantages and limitations.
770 citations
TL;DR: There is a dire need to monitor biogeochemical behavior of Cr in soil-plant system, as Chromium induces phytotoxicity by interfering plant growth, nutrient uptake and photosynthesis, inducing enhanced generation of reactive oxygen species, causing lipid peroxidation and altering the antioxidant activities.

TL;DR: This review summarizes the application of biological technologies, which contains microbial technologies (function microbial remediation and composting or compost addition), biochar, phytoremediation technologies, genetic engineering technologies and biochemical technologies, for the remediation of co-contaminated soil with heavy metals and organic pollutants.
Abstract: Compound contamination in soil, caused by unreasonable waste disposal, has attracted increasing attention on a global scale, particularly since multiple heavy metals and/or organic pollutants are entering natural ecosystem through human activities, causing an enormous threat. The remediation of co-contaminated soil is more complicated and difficult than that of single contamination, due to the disparate remediation pathways utilized for different types of pollutants. Several modern remediation technologies have been developed for the treatment of co-contaminated soil. Biological remediation technologies, as the eco-friendly methods, have received widespread concern due to soil improvement besides remediation. This review summarizes the application of biological technologies, which contains microbial technologies (function microbial remediation and composting or compost addition), biochar, phytoremediation technologies, genetic engineering technologies and biochemical technologies, for the remediation of co-contaminated soil with heavy metals and organic pollutants. Mechanisms of these technologies and their remediation efficiencies are also reviewed. Based on this study, this review also identifies the future research required in this field.

TL;DR: Compared to the other metals studied, Cd, Cu, Zn, and Pb had higher bioavailability in the three zones, which means they pose a higher ecological risk, and the potential ecological risks in the mainstream and tributaries were higher than those in lakes.
