  • Abstract Sponge population partly depends on larval recruitment. Environmental
    factors, e.g. light, salinity, pH and temperature, chemical factors and pollution
    may influence larval settlement and metamorphosis. In this study, the effects
    of galaxolide(HHCB)、tonalide(AHTN)and bisphenol A(BPA)on the
    settlement and metamorphosis of an intertidal sponge (Spongia ceylonensis)
    were examined. The experiments included LC50 test, effects of solvent,
    HHCB, AHTN and BPA on sponge settlement and metamorphosis. In the
    LC50 tests, the 96 hr–LC50 value of HHCB and AHTN all greater than 1.00
    mg/L, and the 96 hr–LC50 of BPA was 0.58 mg/L. Acetone concentration
    (1.00 mg/L ) in this study didn’t affect sponge settlement and metamorphosis.
    Effect of HHCB and AHTN on sponge settlement and metamorphosis
    concentrations of 0.13, 0.25, 0.50 and 1.00 mg/L was insignificant. In
    contrast, the settlement rate was decrease by 20 % at treatment of 1.00 mg/L
    BPA. The metamorphosis rates were also decrease by 20 % and 80 % at
    concentrations of 0.50 mg/L and 1.00 mg/L BPA. In conclusion, the toxicity
    of AHTN was greater than that of HHCB to sponge settlement and
    metamorphosis.
