Human data are also available following several years of exposure and the reported cases of pulmonary effects, attributed to exposure to zirconium, are rare.
Human data are also available following several years of exposure (K3 or
K4 worker cases reported, with very few workers and no information about
dose exposures or co-exposition to other chemicals). Despite suspicion
that inhalation of zirconium should be capable of causing human
pulmonary disease, the reported cases of pulmonary effects, attributed
to exposure to zirconium, are rare. These epidemiological data, in
addition to the absence of effect observed in the repeated dose
toxicity, can be considered as supporting studies
