The available toxicological studies do not show any hazard. Therefore, DNELs for systemic toxicity are not required. Considering the physico-chemical properties and the absence of findings, the substance can be viewed as an inert nuisance dust. Accordingly, for long-term local effects on the respiratory tract, the general exposure limit for inhalable dust is applied.
