Polycyclic aromatic hydrocarbons (PAHs) are common and persistent environmental pollutants produced during the incomplete combustion of fuels. They known for their carcinogenic mutagenic properties. Thus, removal from water bodies is highly crucial has become a critical issue globally. As solution, here an electrospun polycaprolactone (PCL) membrane with mean fiber diameter 2.74 ± 1.3 μm was by...

In line with the growing health trend in Malaysia, more consumers drink herbal tea for medicinal benefits. However, products could be contaminated polycyclic aromatic hydrocarbons (PAHs) from various production sources. There is a little study focused on detection of PAHs species distributed Malaysia. This was performed to investigate content and toxicity selected commercial teas A total seven ...

To construct the macromolecular model of gas coal in Huainan mining area, 13C nuclear magnetic resonance spectroscopy (13C-NMR), X-ray diffraction (XRD), and photoelectron (XPS) tests were used to analyze microstructure characteristics including aromatic ring type, linkage mode, chemical bonding composition. The was simulated optimized by molecular mechanics (MM) dynamics (MD). experimental res...

In this study, a surface-enhanced Raman scattering (SERS) substrate based on high-refractive-index reflective glass beads (HRGBs) was prepared by facile method and successfully applied to the detection of polycyclic aromatic hydrocarbons (PAHs). The HRGB-SERS depositing silver nanoparticles (Ag NPs) onto surface HRGBs. preparation procedure simplified accelerating hydrolysis (3-Aminopropyl) tri...

The level of heavy metals and polycyclic aromatic hydrocarbons (PAH) were determined from agricultural soil collected in Kubanni area Zaria using standard methods. result mean±SD the five study locations; (KP1- KP3) ranges 4.05±0.18-1.25±0.32 for Lead, 4.43±0.11-0.03±0.01 Cadmium,4.30±0.14 - 0.13±0.08 Chromium, 3.32±0.25-1.03±0.13 copper. And 1.80±0.01- 0.02±0.01 Zinc. results persistent organi...

The concentrations of total polycyclic aromatic hydrocarbons (sigmaPAHs) and 15 individual PAH compounds in 20 surface sediments collected from four mangrove swamps in Hong Kong were analysed. sigmaPAH concentrations ranged from 356 to 11,098 ng g(-1) dry weight with mean and median values of 1992 and 1,142 ng g(-1), respectively. These values were significantly higher than those of marine bott...
