Removal Process of Benzo(α)pyrene from Linseed Oil

open access: yesShipin gongye ke-ji, 2022
Aiming at the problem of benzo(α)pyrene residues in linseed oil, a physical adsorption method was used to remove benzo(α)pyrene from linseed oil. The main research methods were as follows: Activated carbon and activated clay were used as adsorbents, and ...

Occurrence of polycyclic aromatic hydrocarbons in human diet - exposure and risk assessment to consumer health

open access: yesRoczniki Panstwowego Zakladu Higieny, 2021
Background. Polycyclic aromatic hydrocarbons (PAHs) are environmental pollutants, they are also present in food, in which their presence results from environmental pollution and food processing processes.

Benzo[A]Pyrene and Benzo[E]Pyrene: Photoreactivity and Phototoxicity toward Human Keratinocytes

open access: yesPhotochemistry and Photobiology, 2022
AbstractPolycyclic aromatic hydrocarbons (PAHs) are a group of organic compounds derived mostly from the incomplete combustion of fossil fuels and biomass. Human skin can absorb PAHs and the uptake increases with their molar mass and lipophilicity. Benzopyrene is high molecular weight PAH frequently appearing in ambient pollution.

Effects of cluster formation on spectra of benzo[a]pyrene and benzo[e]pyrene [PDF]

open access: yesChemical Physics Letters, 2008
Absorption and fluorescence emission spectra of the polycyclic aromatic hydrocarbons benzo[a]pyrene (BaP) and benzo[e]pyrene (BeP) in solution and adsorbed on silica have been obtained and compared to examine the spectroscopic effects of clustering. Molecular mechanics calculations with the UFF potential were done to optimize monomer, dimer and trimer ...

Quantification and health impact assessment of polycyclic aromatic hydrocarbons (PAHs) emissions from crop residue combustion

open access: yesHeliyon, 2022
Emission of Polycyclic Aromatic Hydrocarbon compounds from combustion of crop residue was investigated. Crop residues comprising maize cobs, maize husks, rice husks and bean chaff were burnt in a furnace at a temperature of 400 °C and the emissions from ...

Effect of Smoking and Grilling on Polycyclic Aromatic Hydrocarbons in Ghanaian Tilapia

open access: yesEnvironmental Health Insights, 2023
The study assessed 18 Polycyclic Aromatic Hydrocarbons (PAHs) in O. niloticus (Nile tilapia) sampled from an aquaculture cage (farm) and a wild catch. The PAHs in fish samples were analysed using Gas Chromatography-Mass Spectrometry.

Acetylene Semi‐Hydrogenation by Photocatalysis

open access: yesAngewandte Chemie, EarlyView.
Photocatalytic acetylene semi‐hydrogenation is an emerging light‐driven route to polymer‐grade ethylene, offering a mild alternative to energy‐intensive thermocatalysis. By replacing H2 co‐feed with water or other proton sources, these systems can achieve high selectivity under ambient conditions.
