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 tissues in exposed animals.
