Bioaccumulation is the process where a substance is taken into a living
organism, either from the water or through food, and steadily increases in
concentration (bioconcentrates) as it is stored in the tissues.
The most likely substances to bioaccumulate are those which are poorly
soluble in water but which are highly soluble in the fatty (lipid) tissues of
fish and other organisms.
In summary, PDMS fluids of commercial interest do not bioaccumulate because
they are too large to be absorbed by biological membranes.
