Role of glutathione S-transferases in detoxification of a polycyclic aromatic hydrocarbon, methylcholanthrene.

Chemico-Biological Interactions, 2018
Glutathione S-transferases (GSTs), the versatile phase II biotransformation enzymes, metabolize and detoxify a wide variety of toxic chemical compounds like carcinogens, chemotherapeutic drugs, environmental pollutants and oxidative stress products. GSTs

Determination of Polycyclic Aromatic Hydrocarbons (PAHs) in Shrimp

Journal of Agricultural and Food Chemistry, 2010
A simple and rapid method for determining polycyclic aromatic hydrocarbons (PAHs) in shrimp is described. For sample preparation, the quick and simple QuEChERS procedure was used. Reverse-phase chromatography using an octadecyl silica (C18) column and water/acetonitrile gradient elution was used to separate analyte mixtures. After separation, PAHs were

Detection of interstellar 1-cyanopyrene: A four-ring polycyclic aromatic hydrocarbon.

Science
Polycyclic aromatic hydrocarbons (PAHs) are organic molecules containing adjacent aromatic rings. Infrared emission bands show that PAHs are abundant in space, but only a few specific PAHs have been detected in the interstellar medium.

Polycyclic Aromatic Hydrocarbon (PAH) Degradation Coupled to Methanogenesis

Biotechnology Letters, 2006
Baltimore Harbor (Baltimore, MD) sediments were utilized to initiate anaerobic enrichment cultures with polycyclic aromatic hydrocarbons (PAHs) in the absence of supplementary electron acceptors. Cultures amended with naphthalene and phenanthrene exhibited sustained, transferable degradation of the PAHs.

Review on polycyclic aromatic hydrocarbons (PAHs) migration from wastewater

Journal of Contaminant Hydrology, 2021
Rapidly increasing global population and increased civilization has increased burden on potable water resources and results in larger volumes of wastewater. Physical wastewater management techniques has advanced for domestic usage and commercial effluent new conceptions about imminent wastewater treatment have been acclaimed for highly carcinogenic ...

Polycyclic aromatic hydrocarbons (PAHs) in mangrove ecosystems: A review

Environmental Pollution, 2022
Polycyclic aromatic hydrocarbons (PAHs) are organic pollutants of increasing concern in the different fields of the environment and human health. There are 16 of them that are recognized as priority pollutants by the US environmental protection agency due to their mutagenic and carcinogenic potentials.

Infrared spectra of polycyclic aromatic hydrocarbons (PAHs)

Chemical Physics, 2000
We have computed the synthetic infrared spectra of some polycyclic aromatic hydrocarbons containing up to 54 carbon atoms. The species studied include ovalene, circumcoronene, dicoronylene, and hexabenzocoronene. We report spectra for anions, neutrals, cations, and multiply charged cations.

Polycyclic aromatic hydrocarbons (PAHs) in Chicago air

Science of The Total Environment, 1999
Ambient air samples were collected in Chicago, IL between June and October 1995 as part of a study to investigate the dry deposition and air–water exchange of polycyclic aromatic hydrocarbons (PAHs). A modified high-volume sampler (PS-1 sampler) was used to collect airborne PAHs in both the particulate and gas phases. The average total (gas+particulate)
