PS and biota • Biota EQS set for 11 compounds • EU guidance document currently being developed
– SelecNon of target organism differs between MS – Human health vs secondary poisoning – Require consistency and comparability to assess compliance against
the EQSbiota and in interpretation of data
• PS and biota – Similar drivers for uptake – Environmental factors can be modelled – Metabolism and health status can be complicaNng factors – Suitable where no biota are present
