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...

description |
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 depuration of pyrene in Crassostrea
iredalei. The results reveal that lower salinity will lead to higher bioaccumulation of pyrene in the oyster. Bioaccumulation factors for pyrene in oyster at 10 ppt, 20 ppt and 30 ppt salinity of seawater are 232464 ± 110021, 126137 ± 30255 and 54839 ±
9931 respectively. The uptake rate constants are 1593.486 ± 824.644, 462.707 ± 108.643 and 164.516 ± 38.826 h"1 respectively. 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. Besides, Crassostrea iredalei is also capable to accumulate the PAHs
present in Malaysia Tapis A crude oil. |
