In the US EPA review, a large dataset of aquatic bioaccumulation studies has been investigated; BCF values in this dataset ranged from 0.048 to 1,390. Even if As can be bioconcentrated in aquatic organisms, biomagnification in aquatic food chains does not appear to be significant.
Arsenic acid (AA) is an inorganic compound
of arsenic (As) for which a large number of studies addressing the
bioaccumulation by various aquatic species are available in the
literature. Thus, the study on bioaccumulation of the substance in fish
is scientifically unjustified. Further details are provided in the
endpoint summary 5.3. A weight of evidence approach is proposed to cover
the aquatic bioaccumulation information requirement.
As bioaccumulation depends on various
factors including the environmental setting (marine, estuarine,
freshwater), the type of aquatic organism, the exposure concentration
and duration. In the US EPA review, a large dataset of aquatic
bioaccumulation studies has been investigated; BCF values in this
dataset ranged from 0.048 to 1,390. Even if As can be bioconcentrated in
aquatic organisms, biomagnification in aquatic food chains does not
appear to be significant.
