Bioconcentration of naphthalene in tissues of the white mullet(Mugil curema)

摘要

AbstractNaphthalene concentrations in the gill, liver, spleen and muscle ofMugil curemawere measured before and after exposure to naphthalene concentrations of 0.01, 0.05 and 0.10 mg/L. Naphthalene was rapidly accumulated inM. curematissues and the rate of uptake was much greater than the rate of depuration. The bioconcentration factor (BCF) ranged from 81 to 567 in muscle tissue and was inversely related to exposure concentration. The average BCF for muscle was closely estimated by an equation based on then‐octanol/water partition coefficient. The BCF was highest in the liver and spleen and lowest in muscle and gill tissue
