Oxygenated polycyclic aromatic hydrocarbons in the surface water environment: Occurrence, ecotoxicity, and sources

Environment International, 2022
Oxygenated polycyclic aromatic hydrocarbons (OPAHs) have been ubiquitously detected in atmospheric, soil, sediment, and water environments, some of which show higher concentrations and toxicities than the parent polycyclic aromatic hydrocarbons (PAHs ...

The contamination of bottom sediments in the Southern Baltic with polycyclic aromatic hydrocarbons (PAHs)

Ecocycles, 2016
The study involved a comparative analysis of PAH (polycyclic aromatic hydrocarbons) concentrations in the bottom sediments of the southern part of the Baltic Sea. It was determined that the contamination of sediments with PAHs is considerable (>500 ng/g),

Polycyclic aromatic hydrocarbons in permafrost peatlands

Scientific Reports, 2021
The concentrations of 15 individual PAHs in 93 peat cores have been determined by using high-performance liquid chromatography methods. In the profile the qualitative and quantitative composition of PAHs was non-uniform estimated in a wide range: from ...

Main Emission Sources and Health Risks of Polycyclic Aromatic Hydrocarbons and Nitro-Polycyclic Aromatic Hydrocarbons at Three Typical Sites in Hanoi

Atmosphere, 2023
Particulate matter-bound polycyclic aromatic hydrocarbons (PAHs) and nitro-PAHs (NPAHs) were first systematically studied in downtown (XT), suburban (GL) and rural (DA) sites in winter and summer in Hanoi, Vietnam, from 2019 to 2022.

Bioassays with terrestrial and aquatic species as monitoring tools of hydrocarbon degradation [PDF]

, 2016
In this study chemical analyses and ecotoxicity tests were applied for the assessment of a heavily hydrocarbon-contaminated soil prior and after the application of a remediation procedure that consisted in the stimulation of soil autochthonous ...

Polycyclic aromatic hydrocarbons in soybean grains

Heliyon, 2020
During the burning of the organic material (firewood) in the drying, combustion may occur incompletely, thus generating smoke contaminants such as polycyclic aromatic hydrocarbons (PAHs) in the furnaces.

Evaluation of the content and degradation rates of PAHs in biochars, in terms of assessing the environmental risks of their application for soil remediation

Georesursy
The growing worldwide practice of biochar application as soil ameliorants, as well as adsorbents for remediation of soil contaminated with oil products and heavy metals, can lead to an increase the risk of environmental pollution by pyrolysis by-products.
