Mathematical modeling of PCB bioaccumulation in Perna viridis

摘要

In the present work,we built a mathematical model of polychlorinated biphenyl(PCB)bioaccmulation in Perna viridis, namely, a one-compartment model with a time dependent incorporation rate R(μg g~-1 lipid per ppb water per day), with positive substrate cooperativity as the underlying physical mechanism. The temporal change of the PCB concentration Q(μg g~-1 lipid)in the soft tissues of the mussel depends on the competition of the input rate RW and the output rate kQ, where W is the concentration of PCB in water(ppb water)and k is the elimination rate(per day).
