“…The system of (bio)functionalized NPs has nano-adsorptive and catalytic degrading properties in order to remove PAHs from the polluted environment (Basak et al, 2020). Wang et al (2015) demonstrated benzo(a)pyrene degradation from polluted surface and subsurface soil using silica NPs coated with zwitterionic lipid (1,2-dimyristoylsn-glycero-3-phosphocholine) bilayers.…”

“…The lipid-based (bio)functionalized silica NPs provided two methods of remediation: (1) sequestration of benzo(a)pyrene by adsorption and (2) providing colloidal stability necessary for transport to the polluted source (Wang et al, 2015). Shanker et al (2017) have synthesized iron hexacyanoferrate (FeHCF) NPs (10-60 nm size) of various shapes (hexagonal, rod, and spherical) using plant origin biosurfactant (saponins) extracted from Sapindus mukorossi and water as solvent.…”

Polycyclic aromatic hydrocarbons (PAHs) are widespread across the globe mainly due to long-term anthropogenic sources of pollution. The inherent properties of PAHs such as heterocyclic aromatic ring structures, hydrophobicity, and thermostability have made them recalcitrant and highly persistent in the environment. PAH pollutants have been determined to be highly toxic, mutagenic, carcinogenic, teratogenic, and immunotoxicogenic to various life forms. Therefore, this review discusses the primary sources of PAH emissions, exposure routes, and toxic effects on humans, in particular. This review briefly summarizes the physical and chemical PAH remediation approaches such as membrane filtration, soil washing, adsorption, electrokinetic, thermal, oxidation, and photocatalytic treatments. This review provides a detailed systematic compilation of the eco-friendly biological treatment solutions for remediation of PAHs such as microbial remediation approaches using bacteria, archaea, fungi, algae, and co-cultures. In situ and ex situ biological treatments such as land farming, biostimulation, bioaugmentation, phytoremediation, bioreactor, and vermiremediation approaches are discussed in detail, and a summary of the factors affecting and limiting PAH bioremediation is also discussed. An overview of emerging technologies employing multi-process combinatorial treatment approaches is given, and newer concepts on generation of value-added by-products during PAH remediation are highlighted in this review.

“…Green nanoremediation as a nature-based technology offers numerous promises for the cleanup and restoration of polluted soils such as crude oil polluted soils with reference to the efficiency of the process, energy consumed and the global need for eco-friendly processes [116]. Wang et al [117] reported the use of silica nanoparticles capped with lipid bilayers of Pseuodomonas aeruginosa as method of cleaning up of PAH (benzo[a]pyrene) from contaminated soil surface.…”

Crude Oil - New Technologies and Recent Approaches

View full text Add to dashboard Cite

Globally, the environment is facing a very challenging situation with constant influx of crude oil and its derivatives due to rapid urbanization and industrialization. The release of this essential energy source has caused tremendous consequences on land, water, groundwater, air and biodiversity. Crude oil is a very complex and variable mixture of thousands of individual compounds that can be degraded with microbes with corresponding enzymatic systems harboring the genes. With advances in biotechnology, bioremediation has become one of the most rapidly developing fields of environmental restoration, utilizing microorganisms to reduce the concentration and toxicity of various chemical pollutants, such as petroleum hydrocarbons, polycyclic aromatic hydrocarbons, polychlorinated biphenyls, phthalate esters, nitroaromatic compounds and industrial solvents. Different remediation methods have been introduced and applied with varied degrees of success in terms of reduction in contamination concentration without considering ecotoxicity and restoration of biodiversity. Researchers have now developed methods that consider ecotoxicology, environmental sustainability and ecorestoration in remediation of crude oil impacted sites and they are categorized as biotechnological tools such as bioremediation. The approach involves a natural process of microorganisms with inherent genetic capabilities completely mineralizing/degrading contaminants into innocuous substances. Progressive advances in bioremediation such as the use of genetically engineered microbes have become an improved system for empowering microbes to degrade very complex recalcitrant substances through the modification of rate-limiting steps in the metabolic pathway of hydrocarbon degrading microbes to yield increase in mineralization rates or the development of completely new metabolic pathways incorporated into the bacterial strains for the degradation of highly persistent compounds. Other areas discussed in this chapter include the biosurfactant-enhanced bioremediation, microbial and plant bioremediation (phytoremediation), their mechanism of action and the environmental factors influencing the processes.

“…In another study performed by Machado et al, (2013) the treatment of ibuprofen contaminated sandy soil was performed with the help of nZVI and observed that he nZVI produced from vine extracts could successfully degrade ibuprofen with the highest degradation efficiency of 62%. Wang et al, (2015) successfully demonstrated the viability of silica nanoparticle supported zwitterionic lipid bilayer in treating benzo-a-pyrene, a hydrophobic polycyclic aromatic hydrocarbon. Decabromodiphenyl ether, a type of polybrominated diphenyl ethers present in soil were treated using biochar supported Fe/Ni bimetallic nanoparticles with the removal efficiency reaching to nearly 88% within 72 h of the treatment.…”

Nanoremediation technologies for sustainable remediation of contaminated environments: Recent advances and challenges

A major and growing concern within society is the lack of innovative and effective solutions to mitigate the challenge of environmental pollution. Uncontrolled release of pollutants into the environment as a result of urbanisation and industrialisation is a staggering problem of global concern. Although, the eco-toxicity of nanotechnology is still an issue of debate, however, nanoremediation is a promising emerging technology to tackle environmental contamination, especially dealing with recalcitrant contaminants. Nanoremediation represents an innovative approach for safe and sustainable remediation of persistent organic compounds such as pesticides, chlorinated solvents, brominated or halogenated chemicals, perfluoroalkyl and polyfluoroalkyl substances (PFAS), and heavy metals. This comprehensive review article provides a critical outlook on the recent advances and future perspectives of nanoremediation technologies such as photocatalysis, nano-sensing etc., applied for environmental decontamination. Moreover, sustainability assessment of nanoremediation technologies was taken into consideration for tackling legacy contamination
