Toluene is an air pollutant widely used as an organic solvent in industrial production and emitted by fossil fuel combustion. It is a highly flammable and commonly used industrial chemical with severe health consequences on humans upon exposure and ingestion. Toluene has central nervous system depressant effects.
Toluene has a complex mechanism of action and broad behavioral effects, among which memory impairment is reported consistently. Toluene was oxidized by [(N4Py)Fe(IV)(O)](2+) in the presence of HClO4 in acetonitrile (MeCN) to yield a stoichiometric amount of benzyl alcohol.
Toluene has been used as void volume (zero retention) marker since the inception of hydrophilic interaction chromatography (HILIC) Toluene is a non-classical hallucinogen drug through activation of 5-HT.
Toluene can cause acute neurological symptoms, accompanied by severe metabolic alterations, as well as organ injury and dysfunction. Toluene was found to enhance the catalytic efficiency of the reactor for p-xylene.

Toluene treatment was most efficient when carried out for 5 min at 37 C at pH 9.0 on log-phase cells. Toluene-treated Chlamydomonas reinhardi incorporate deoxynucleoside triphosphates (dNTPs) into DNA. Treatment with toluene and MTBE also affected the behavior and morphology of P. reindeer.
The research of benzene and toluene toxic effects has been carried out in the Republic of Croatia. The results extended the knowledge on toxic effects of toLUene, ethylbenzene and xylene on aquatic plants.
