Bioaccumulation and depuration of pyrene in oyster, crassostrea iredalei

Oyster, Crassostrea iredalei is able to accumulate pyrene in seawater rapidly and achieve steady state within 24 hours under static condition of seawater containing salinity between 10 ppt and 30 ppt, at 30 °C temperature and pH 8.1. Salinity seems to have a great effect on the accumulation and d...

The depuration rate constants are 0.007 ± 0.001, 0.004 ± 0.001 and 0.003 ± 0.00 h"1 respectively. Higher salinity level leads to lower bioaccumulation factor as well as uptake and depuration rate constants.
