C.I. Pigment Yellow 184 does not significantly accumulate in organisms as expected regarding the extremely low water solubility. The bioconcentration factors determind in a study on Oryzias latipes ranged from < 1.2 to <14.

This is supported by data on vanadium. In a review by Miramand & Fowler (1998) data from areas of likely local contamination from industrial sources are reported. The authors calculated concentration factors for components of a typical marine food chain based on average seawater concentrations of 2 ng/g and reported levels of vanadium in marine organisms.

Concentration factors for primary producers ranged from 40 to 560, for primary consumers from 40 to 150, for secondary consumers from approximately 20 to 150, and for tertiary con sumers from approximately 2 to 400.

With the exception of ascidians (tunicates), some annelids, and molluscs, concentrations of vanadium in marine organisms are low

Organisms generally do not concentrate or accumulate vanadium from environmental media to a high degree, and there is no indication of biomagnification in food chains.
