Outline of Final Research Achievements

We synthesized the analytical standards of halogenated polycyclic aromatic hydrocarbons (XPAHs) including tri-Chloropyrene and tetra-Chloropyrene, which are environmental pollutants with high potential risk. The concentrations of 26 XPAHs in sediment and fish samples collected from Tokyo bay were measured. To investigate the bioaccumulation potential of XPAHs, the biota-sediment accumulation factors (BSAFs) were calculated by the XPAH concentrations in fish (lipid weight) and sediment (organic carbon weight) samples.
