“…Nanoparticle (NP)-based eco-engineered bioremediation strategy signifies key emerging research fields to deal with pollutants like PAHs from various matrices such as soil, sediment, surface water, and groundwater. The development in NPs demands additional improvement like enhancement of their characteristics through modification in surface properties called "functionalized nanoparticles, " which are able to play multifunctional roles in the bioremediation field (Basak et al, 2020). Bionano-remediation employs a large range of biomolecules as functionalizing agents, mainly enzymes, proteins, DNA, humic acids, and biosurfactants, for remediating many petroleum hydrocarbons including PAHs (Basak et al, 2020).…”

“…The added advantages of NPs are efficient reactivity and offering higher surface area due to their nano-scale size. 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.…”

Polycyclic Aromatic Hydrocarbons: Sources, Toxicity, and Remediation Approaches

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.

Nanotechnology implies the scientific research, development, and manufacture, along with processing, of materials and structures on a nano scale. Presently, the contamination of metalloids and metals in the soil has gained substantial attention. The consolidation of nanomaterials and plants in ecological management has received considerable research attention because certain nanomaterials could enhance plant seed germination and entire plant growth. Conversely, when the nanomaterial concentration is not properly controlled, toxicity will definitely develop. This paper discusses the role of nanomaterials as: (1) nano-pesticides (for improving the plant resistance against the biotic stress); and (2) nano-fertilizers (for promoting the plant growth by providing vital nutrients). This review analyzes the potential usages of nanomaterials in agroecosystem. In addition, the adverse effects of nanomaterials on soil organisms are discussed. We mostly examine the beneficial effects of nanomaterials such as nano-zerovalent iron, iron oxide, titanium dioxide, nano-hydroxyapatite, carbon nanotubes, and silver- and copper-based nanomaterials. Some nanomaterials can affect the growth, survival, and reproduction of soil organisms. A change from testing/using nanomaterials in plants for developing nanomaterials depending on agricultural requirements would be an important phase in the utilization of nanomaterials in sustainable agriculture. Conversely, the transport as well as ecological toxicity of nanomaterials should be seriously examined for guaranteeing its benign usage in agriculture.

“…Currently, new developments are made in the field of bioremediation which is thenanoparticle based eco-engineered bioremediation method which helps in reducing the compounds like PAH emerging from different sources involving water, soil and sediments . This technique mainly involves biomolecules like bio-surfactants, humic acids, proteins and enzymes which act as functionalizing agents (Basak et al,2020). The biodegradation mainly focuses on degrading the PAH present in water sources and soil with the help of several types of plants, microorganisms, and different types of enzymatic reactions (Ghosal et al,2016., Gouma, Fragoeiro, Bastos andMagan, 2014).…”

<p>Polycyclic Aromatic Hydrocarbons (PAHs) are aromatic hydrocarbons with three or more fused benzene rings that include carbon and hydrogen. These are thought to be harmful to human health, and we cannot avoid being exposed to them because they are widely disseminated throughout the environment. PAHs enter our bodies through the air, water, food, and soil. The developments in different sources of generation, analysis, and remediation approaches are reviewed in this paper based on recent available literature. The chemistry of PAHs, their exposure routes, and their health implications are also discussed. In this manuscript future scope of work as well as removal and reduction of carcinogenic PAHs are also discussed briefly. These types of review article are one of the most promising solutions to reduce air pollution issues from environment. This study could be one of the best studies to reduce carcinogenic pollutants from our environment.</p>
