How is acenaphthylene aromatic
WebPolycyclic aromatic hydrocarbons (PAHs), which are generated from the incomplete combustion of organic (carbonaceous) mate-rial, are ubiquitous contaminants in ambient … WebIn the present study, the effect of polycyclic aromatic hydrocarbons (PAHs) on isolated rat aorta was investigated. Acenaphthylene and naphthalene dose-dependently relaxed the phenylephrine-induced contraction of rat aorta with 50% vasorelaxation at 40.8 ± 19.83 and 118.75 ± 9.83 μM, respectively.
