Other animal data: Rats exposed to 20 ppm for 7 hours per day for 20 days exhibited only eye and nasal irritation [Hefner et al. 1975]. Human data: It has been reported that industrial experience has shown no evidence that phenyl ether, either as a liquid, mist, or vapor, is a health hazard under ordinary conditions of production and use; no overt systemic toxicity was found at concentrations that were not intolerably disagreeable [Clayton and Clayton 1981]. |
