12. Research on analysis method for determination of polycyclic aromatic Hydrocarbon (PAHs) concentration in ambient air using HPLC - FLD

Abstract

Polycyclic aromatic hydrocarbons (PAHs) are toxic chemicals linked to cancer and congenital heart defects. PAHs are found in the ambient air in the gas phase and as a sorbet to aerosols, but PAHs on airborne particles are more attractive to research. This study investigated the conditions for preparing dust samples and operating HPLC - FLD equipment to quantify PAHs in total suspended particulate matter (TSP). The mixture of solvent Dichloromethane (DCM) and Acetone (Ace) (9:1, v/v) was used to extract using the solid-liquid extraction technique, and the mobile phase for reversed-phase HPLC was Acetonitrile and H₂O. After that, three TSP samples were taken and processed to analyze the PAHs in the samples.
