title: Measurement of the uptake of a 14C-labelled fluorescent whitening agent by fish from water and through a model food chain.
abstract: A laboratory technique is described which simulates the uptake of a fluorescent whitening agent by fish directly from the water and indirectly through a model food chain. The use of radioactive labelled material enables the direct and indirect uptake and possible accumulation of the compounds to be measured quantitatively. The results are expressed as concentration factors. Between ecological and toxicological data a safety relationship is established.
