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.
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 makes a deeper level of anesthesia achievable more easily using anesthetic gases but can also make them more dangerous than other drugs used for this purpose. Nitrous oxide is thought to be particularly non-toxic, though heavy long-term use can lead to a variety of serious health problems linked to the destruction of vitamin B12 and folic ...
Many gases have toxic properties, which are often assessed using the LC 50 (median lethal concentration) measure. In the United States, many of these gases have been assigned an NFPA 704 health rating of 4 (may be fatal) or 3 (may cause serious or permanent injury), and/or exposure limits (TLV, TWA/PEL, STEL, or REL) determined by the ACGIH professional association.
Tobacco smoke may be grouped into a particulate phase (trapped on a glass-fiber pad, and termed "TPM" (total particulate matter)) and a gas/vapor phase (which passes through such a glass-fiber pad). "Tar" is mathematically determined by subtracting the weight of the nicotine and water from the TPM.
The gas industry and its GOP allies in Congress say regulations taking gas stove models off the market unfairly limit consumer choice. “Fifty percent of the market will not comply with DOE’s rule.
A documentary by Karen Davila showed the effects of inhalant abuse on a person's body. [1] The chemical toluene provides the aromatic smell of contact cement and other glue and is the culprit behind the addiction. Toluene abusers are exposed to levels above 1000 ppm (parts per million). Levels of exposure greater than 600 ppm cause confusion ...
The main health concern with gas stoves is that they’re the only appliance that vents pollution directly into the home, Rob Jackson, Ph.D., a professor of earth system science at Stanford ...
