Bioconcentration and Depuration of 16 Priority Polycyclic Aromatic Hydrocarbons in Mariculture Fish Lateolabraz Japonicus
Fish are effective sensitive to organic pollutants in the aquatic environment. Lateolabrax japonicus is an important mariculture fish in southeastern seas of China. In the present study, we determined concentrations of 16 EPA priority PAHs in seawater, liver and bile of Lateolabrax japonicus using GC/MS techniques. 1-pyrenol and naphthol concentrations in bile were also determined by fluorescence methods in order to investigate their clearance and metabolism. Results show that: (1) Bioconcentration factor (BCF) values in liver increase with the increasing PAHs’ molecular weights; (2) the PAHs with higher molecular weight are more easily depurated than the ones with lower molecular weight; (3) The BCF of naphthalene and acenaphthlene in bile are much higher than those of the other PAHs indicating that naphthalene and acenaphthlene are more difficult to be metabolized and depurated in Lateolabrax japonicus; (4) pyrene exposure in seawater can stimulate its metabolism in liver of Lateolabrax japonicus; (5) A good relationship was found between pyrene concentration in seawater and 1-pyrenol concentration in bile, it suggested that 1-pyrenol concentration in bile might be used to indicate pyrene contamination level in seawater.
