Distribution of Nitro-Polycyclic Aromatic Hydrocarbons in Soil of Hangzhou Bay Using HPLC Fluorescence Detection and Source Analysis
The objective of this study was to develop an efficient and sensitive analytical protocol for the determination of nitrated polycyclic aromatic hydrocarbons (NPAHs) in soil samples around Hangzhou bay. The separation of 16 NPAH (mono-and dinitro-PAH) was achieved by reversed-phase high performance liquid chromatography (HPLC) followed by on-line reduction of the NPAHs to their corresponding amino polycyclic aromatic hydrocarbons (APAHs) and quantification by fluorescence detection. The main factors affecting the on-line reduction efficiency, such as the flow rate, the temperature, the position and packing of the reduction column were evaluated and optimized. This analytical method was applied to surface soil samples collected around Hangzhou bay, south of China. The concentrations observed for this site showed Hangzhou bay was polluted by NPAH to some degree. Among all the 15 NPAHs measured in the experiment, only 1,3-Dinitropyrene and 1,6-Dinitropyrene were not detected in all samples. Two kinds of NPAH, named 2-Nitrofluoranthene and 6-Nitrochrysene, were the most abundant NPAHs. They account respectively for about 14.3% and 26.5% of the total studied NPAH concentration.
