Vanadium compounds act chefly as an
irritant to the conjunctiva and respiratory
tract. Acute and chronic exposure can gve
rise to conjunctivitis, rhinitis, reversible
irritation of the respiratory tract, and to bronchitis, bronchospasms, and asthma-like
dlseases in more severe cases. There is sull
some controversy as to the effects of
industrial exposure on other systems of the
body. Responses are mostly acute, seldom
chronic. The first report of human
vanalum poisoning described rather
widespread systemic effects, consisting of
polycythemia, followed by red blood cell
destruction and anemia, loss of appetite,
pallor and emaciation, albuminuria and
hematuria, gastrointestinal disorders,
nervous complaints, and cough, sometimes
severe enough to cause hemoptysis. More
recent reports describe symptoms that, for
the most part, are restricted to the conjunct-
iva and respiratory system, no evidence
being found of disturbances of the gastroin-
testinal tract, kidneys, blood, or central
nervous system. Vanadate (VO3-) is a potent
inhibitor of the sodium pump, an enzyme
universally present in eukaryotic organisms.
The absorption of V2O5 by inhalation is
nearly 100%. Though certain workers
believe that it is only the pentoxide that is
harmful, other investigators have found that
patronite dust (chiefly vanadmm sulfide) is
quite toxic to animals, causing acute
pulmonary edema. Acute poisoning in
animals by ingestion of vanadlum com-
pounds causes nervous dlsturbances,
paralysis of legs, respiratory fdure,
convulsions, bloody darrhea, and death.
Poisoning by inhalation causes bleeding of
the nose and acute bronchtis. Some
compounds have reported mutation effects.
VF5 and the oxyhalogenides of pentavalent
vanadium (VOF3, VOCl3, VOBr3) are
volatile. Vanadmm compounds are common
air contaminants. The fumes are highly
toxic. The major use of vanadmm and its
alloys is in the steel industry. When heated
to decomposition they emit toxic fumes of
VOx. See also specific compounds. |
