The WHO (1998) review of boron noted that
highly water soluble materials are unlikely to bioaccumulate to any
significant degree and that borate species are all present essentially
as undissociated and highly soluble boric acid at neutral pH. The
available data indicate that both experimental data and field
observations support the interpretation that borates are not
Boron is known to be a critical element for
the normal growth and productivity of aquatic and terrestrial plants.
Boron is incorporated into plant cell walls, so some accumulation from
the environment may be anticipated, i.e., active transport. The minimum
required level in plants is dependent on the plant species.
While several studies report concentrations
on boron in plant tissues, only few provide both soil and tissue
concentrations: these are the data required to derive the Biota Soil
Accumulation Factor (BSAF) values, which can be found in section 4.3.1
and 4.3.2. These values are well below BSAF values used to establish
significant bioconcentration (BSAF 3000 to 5000).

attached to section 13.
