End so on
It looks great but we stilllook at a log scale
Predictions from PS would still need to use (variable) literature BCF or BAFs
!!How to get around that?

Sampler-lipid partition coefficients (KP,L or KL,P)
• Not different for lipids
• Not affected by lipid uptake in the sampler
• No measurable temperature effect
• Are relatively small
and can therefore be accurately measured

Can we predict concentrations in biota?
So, although biota is still to variable
passive sampling can givea prediction for
a lipid based concentration that biota would have if they were in equilibrium with their
environment

Advantages Worldwide comparableDifferent waters Fresh and saline water, toxic, anoxic, porewater
