The first four seem to be involved in the hydroxylation of toluene to benzyl alcohol. CYP2E1 seems to be the primary enzyme in the hydroxylation of toluene, accounting for roughly 44% of toluene metabolism; [1] however, there is a great deal of ethnic variability, in the Finnish population for example the primary enzyme is CYP2B6.
The original edition, known as the Toxic Substances List was published on June 28, 1971, and included toxicological data for approximately 5,000 chemicals. The name changed later to its current name Registry of Toxic Effects of Chemical Substances. In January 2001 the database contained 152,970 chemicals.

Toxic encephalopathy is a neurologic disorder caused by exposure to neurotoxic organic solvents such as toluene, following exposure to heavy metals such as manganese, as a side effect of melarsoprol treatment for African trypanosomiasis, adverse effects to prescription drugs, or exposure to extreme concentrations of any natural toxin such as cyanotoxins found in shellfish or freshwater ...
Toluene is also found in cigarette smoke and car exhaust. If not in contact with air, toluene can remain unchanged in soil or water for a long time. [39] Toluene is a common solvent, e.g. for paints, paint thinners, silicone sealants, [40] many chemical reactants, rubber, printing ink, adhesives (glues), lacquers, leather tanners, and ...
This data is frequently screened for quality, relevancy and ideally contains data for species in multiple trophic levels and/or taxonomic groups. [1] [6] The lowest LC50 in the compiled database is then divided by the assessment factor to calculate the PNEC for that data. The assessment factor applied to acute toxicity data is typically 1000 ...
Toxic leukoencephalopathy may also result from carbon monoxide poisoning, ingestion of methanol, ingestion of ethylene, [8] toluene toxicity, [3] ethanol poisoning, ingestion of methylenedioxymethamphetamine (MDMA or "ecstasy"), or ingestion of paradichlorobenzene, [18] which is a toxic agent in mothballs.
Dinitrotoluenes are highly toxic with a threshold limit value (TLV) of 1.5 mg/m 3. [7] It converts hemoglobin into methemoglobin. 2,4-Dinitrotoluene is also a listed hazardous waste under 40 CFR 261.24. Its United States Environmental Protection Agency (EPA) Hazardous Waste Number is D030. The maximum concentration that may be contained to not ...
