WebPhenol ionises at higher pH and it could be expected that its toxicity would be higher in the un-ionised form, i.e. at lower pH values, where penetration of biological membranes would be greater (Kaila & Saarikoski 1977). Flerov (1973) and Herbert (1962) found that the toxicity of phenol to fish varied little over intermediate pH values, e.g. 5 ... WebS.T. Dydek, in Encyclopedia of Toxicology (Third Edition), 2014 Phenols. Phenols are rapidly and efficiently absorbed through skin, lungs, and the gastrointestinal tract; 70–80% of inhaled phenol is absorbed by humans within an 8-h exposure. Six-hour dermal exposures to phenol also resulted in 70–80% absorption in humans. Phenol is rapidly distributed to all …
