Sodium pentaborate is converted into boric acid/borate upon dissolution
in water. Boric acid is an inorganic compound and not degradable. It is
not subject to hydrolysis, photodegradation or biodegradation. Other
borates yield boric acid upon dissolution in water (or borate anion in
higher pH conditions). Over 200 minerals contain boron, mostly present
as the sodium or calcium borate salt. Boron and its inorganic compounds
are subject to chemical transformation precipitation, and fixation) once
released to the environment.
Methods used to determine persistence of organic chemicals are measures
of the production of CO2, uptake of O2, or reduction in dissolved or
total organic carbon. Such methods are clearly not applicable to
inorganic substances. Persistence/degradability has therefore limited or
no meaning for inorganic substances according to the Organization for
Economic Cooperation and Development (OECD, 2001). Rather the substance
may be transformed by normal environmental processes to modify the
availability of chemical species.
