Polycyclic aromatic hydrocarbons (PAHs) are mostly formed during the incomplete combustion of organic materials, but their importance and presence in materials science, astrochemistry has also been proven. These carcinogenic persistent pollutants essential formation generated particles as well. Due to significant impact on environment human health, understand growth PAHs is essential. Therefore, most important mechanisms reviewed, presented here from past four decades (1981–2021) initiate discussions a new perspective. Although, collected analyzed observations derived both experimental, computational studies, it neither systematic nor comprehensive review. Nevertheless, were divided into three main categories, acetylene additions (e.g. HACA), vinylacetylene (HAVA), radical reactions, discussed accordingly.

The petroleum industry’s development has been supported by the demand for and its by-products. During extraction transportation, however, oil will leak into soil, destroying structure quality of soil even harming health plants humans. Scientists are researching developing remediation techniques to repair re-control afflicted environment due risks social implications hydrocarbon contamination. Remediation contamination produced hydrocarbons, on other hand, is a difficult time-consuming job. Microbial focus because convenience use, lack secondary contamination, low cost. This review lists types capacities microorganisms that have investigated degrade hydrocarbons. However, investigations revealed single microbial faces difficulties, such as inconsistent effects substantial environmental consequences. It necessary understand composition source pollutants, metabolic genes pathways degradation internal external aspects influence in order select optimal treatment strategy. compares abilities microbial–physical, chemical, combination methods, highlights capabilities processes greatest microbe-biochar, microbe–nutrition, microbe–plant technologies. helps evaluating forecasting chemical behavior contaminants with both short- long-term Although there integrated strategies removal practical remains difficult. sources quantities well their impacts plants, humans, discussed this article. Following that, shifted microbiological technique degrading pollutants mechanism combined method. Finally, limitations existing highlighted.

Remediation of soil polluted with petroleum hydrocarbons and its reuse for agriculture: Recent progress, challenges, and perspectives

Chemosphere, Год журнала: 2022, Номер 293, С. 133572 - 133572

Опубликована: Янв. 8, 2022

Petroleum hydrocarbons (PHs) are used as raw materials in many industries and primary energy sources. However, excessive PHs act soil pollutants, posing serious threats to living organisms. Various ex-situ or in-situ chemical biological methods applied restore polluted soil. most of the treatment expensive, environmentally unfriendly, sometimes inefficient. That attracts scientists researchers develop select new strategists remediate through risk-based analysis eco-friendly manner. This review discusses sources PHs, properties, distribution, transport, fate environment, internal external factors affecting remediation restoration process, its effective re-utilization for agriculture. Bioremediation is an method degrading specifically by using microorganisms. Next-generation sequencing (NGS) technologies being monitor contaminated sites. Currently, these have caused a paradigm shift giving insights into microbially mediated biodegradation processes targeting rRNA discussed concisely. The recent development management contamination challenges future perspectives also discussed. Furthermore, nanotechnology seems very promising remediation, but success depends on cost-effectiveness. paper suggests bio-electrochemical systems that utilize electro-chemically active microorganisms with would be eco-friendlier help tailor-made sustainable technologies.

Polycyclic aromatic hydrocarbons (PAHs): Updated aspects of their determination, kinetics in the human body, and toxicity

Journal of Toxicology and Environmental Health Part B, Год журнала: 2023, Номер 26(1), С. 28 - 65

Опубликована: Янв. 2, 2023

Polycyclic aromatic hydrocarbons (PAHs) are legacy pollutants of considerable public health concern. arise from natural and anthropogenic sources ubiquitously present in the environment. Several PAHs highly toxic to humans with associated carcinogenic mutagenic properties. Further, more severe harmful effects on human- environmental have been attributed presence high molecular weight (HMW) PAHs, that is mass greater than 300 Da. However, research has conducted using low (LMW) PAHs). In addition, no HMW priority list United States Environmental Protection Agency (US EPA), which limited only 16 PAHs. analytical methodologies for separating determining their potential isomers lack readily available commercial standards make these compounds challenging. Since most PAH kinetic data originate animal studies, our understanding still minimal. current knowledge after exposure may be underrepresented since investigations focused a single PAH. Currently, information mixtures limited. Thus, this review aims critically assess chemical properties, disposition, toxicity humans. future needs improve provide missing minimize

Mycoremediation as a Potentially Promising Technology: Current Status and Prospects—A Review

Applied Sciences, Год журнала: 2023, Номер 13(8), С. 4978 - 4978

Опубликована: Апрель 15, 2023

Global environmental pollutants are becoming intense because of the increasing human population, urbanisation, and industrialisation. Human health ecosystem affected by soil water contamination. Therefore, creating strategies is essential to tackle this persistent issue. In process, risk associated with these can be signifi-cantly reduced. Previously, traditional remediation techniques have been employed in combating pollutants, proving ineffective. Mycoremediation, which uses fungi or their compounds remediate has shown a cost-efficient, environmen-tally friendly, effective method that includes organic, inorganic, emerging contaminants (antibiotics, pharmaceuticals). This review provides an overview various mycoremediation approaches through for biosorption, precipitation, biotransfor-mation, sequestration pollutants. addition, removal metals, persis-tent organic other was highlighted. For example, such as Pleurotusdryinus, Trameteshirsuta MK640786, Aspergillusniger shows 91%, 94%, 98.4% degradation ranging from pesticides azo dyes, respectively. Furthermore, prospects remove heavy metals waters soils were discussed. It elucidated great potential pharmaceuticals, polycyclic aromatic hydrocarbons (PAHs), pesticides, weedicides. The findings suggested knowledge gap exists enhance rate process. possible framework proposed facilitate promising technology rectifying global problems. procedures possible, further studies needed on fungal enzymes’ role, activities, regulation.
