Distribution and Toxic Equipvalent Assessement of Polycyclic Aromatic Hydrocarbons (Pahs) in Particulate Matter Emmited from Rice Straw Open Field Burning in Hanoi
Abstract:This study investigated the distribution of PAHs content in particulate matter emitted from the open burning of rice straw in Hanoi. Fine particles (PM2.5) was collected using a MiniVol TAS device and the total suspended particles (TSP) was collected using a high-volume sampler Staplex. PAHs in particulate matter were analyzed by HPLC-FL with fluorescent detector. The results showed that 4-ring PAHs was dominant in particles emitted from rice straw burning, especially the most abundant PAHs was Flu: 57.8 37.1… Show more
