Polycyclic aromatic hydrocarbon (PAH) residues in the honeybee, honey, and pollen and estimation of atmospheric concentrations in Bursa, Turkey

, 2023
Polycyclic aromatic hydrocarbon (PAH) concentrations in urban and semi-urban areas were determined in the honeybee, honey and pollen in Bursa, Turkey. The total of 14 PAH ( n-ary sumation (14)PAH) concentrations measured in the honeybee in the urban and ...

Recent Advances in Sample Preparation and Chromatographic/Mass Spectrometric Techniques for Detecting Polycyclic Aromatic Hydrocarbons in Edible Oils: 2010 to Present

Foods
Polycyclic aromatic hydrocarbons are considered to be potentially genotoxic and carcinogenic to humans. For non-smoking populations, food is the main source of polycyclic aromatic hydrocarbons exposure.

Improving fine molybdenite flotation using a combination of aliphatic hydrocarbon oil and polycyclic aromatic hydrocarbon

Results in Physics, 2019
Kerosene is widely used as a collector in molybdenite flotation. However, it can only adsorb on molybdenite faces but not on molybdenite edges, which is unfavorable for the flotation of fine molybdenite particles with high edge/face ratios. In this study,

Rapid measurement of polycyclic aromatic hydrocarbon contamination in soils by visible and near-infrared spectroscopy [PDF]

, 2013
Polycyclic aromatic hydrocarbons (PAHs) are widely distributed organic pollutants. At petroleum contaminated sites, PAHs are often the key risk drivers because of their carcinogenicity. Assessing the risk of PAH at contaminated sites by conventional soil

Solid-liquid organic matter interaction mechanism between kerogen and aromatic compounds

Shiyou shiyan dizhi
Under geological conditions, the initial generation of oil and gas in source rocks reaches saturation before being expelled and migrating, with the adsorption of hydrocarbons by kerogen being a key factor influencing oil saturation.

Strain-induced skeletal rearrangement of a polycyclic aromatic hydrocarbon on a copper surface

Nature Communications, 2017
Mechanical strains can induce chemical transformations otherwise inaccessible by conventional stimuli. Here, the authors show the unusual strain-induced transformation of a polycyclic aromatic hydrocarbon on a metal surface by means of atomic force ...

Cyclic Alkyne Approach to Heteroatom-Containing Polycyclic Aromatic Hydrocarbon Scaffolds

, 2019
We report a modular synthetic strategy for accessing heteroatom-containing polycyclic aromatic hydrocarbons (PAHs) that relies on the controlled generation of transient heterocyclic alkynes and arynes.

Surgical smoke-related occupational injuries among medical professionals in the operating room

Journal of International Medical Research
Objective The use of energy devices during surgery can cause the spread of surgical smoke into the operating room. The concentration of smoke particles during laparoscopic surgery is higher than that during open surgery.
