- OSHA does not have a PEL for 3-phenyltoluene, and its toxicological properties (e.g., acute LD50, LC50, toxicokinetics, and chronic effects in animals) have not been fully investigated.
- 3-Phenyltoluene should be handled with caution, since the occupational exposure to a compound with similar chemical structure, diphenyl, has been associated with toxicity to the peripheral and central nervous systems, including a significantly increased risk for the development of Parkinson's disease.
