PFOS (perfluorooctane sulfonate) is one of the perflourinated organic compound,which persist as a residual compound in the coastal environments. Intertidal mud crab Macrophthalmusjaponicus mainly inhabits in coastal and bay ecosystems in Indo-Pacific region includingKorea and reflects to environmental changes. In the present study, M. japonicus were exposed todifferent concentrations of PFOS and various ecotoxicological end-points such as survival rate,elimination of appendages, changes of the crust and internal organ color changes were investigated.
Interestingly, the PFOS exposure showed concentration-dependent decrease of survival rate.
High PFOS exposure (30 μg L-1) showed a low survival rate of 24% at 168 hours. Further, incomparison with the controls, the rate of elimination of appendages was also considerably increasedin a time dependent manner upon PFOS exposure. Notably, with progression of time, anincreased exposure to PFOS, test species showed whitening effect in a concentration-dependentmanner, whereas the crab crust color was unchanged in the control. In addition, change in internalorgans color and their visibility (clarity) observed in PFOS exposed crabs compared to control.
Taken together, we suggest, eco-toxicology end-points of M. japonicus exposed to PFOS gaveimportant biological information which could be useful to identify toxic contamination in themarine benthic environments.
