Benzene is an acute as well as a chronictoxicant. The acute toxic effects from inhalation,ingestion, and skin contact are low tomoderate. The symptoms in humans are hallucination,distorted perception, euphoria, somnolence,nausea, vomiting, and headache. Thenarcotic effects in humans may occur from...
active pollutant in the environment. People can be exposed to benzene from tobacco smoke, car emissions, and automobile exhaust. Workers in industrial sites are exposed to high levels of benzene more than any other category of people. Benzene goes by other names, most of which are summarized ...
1,2,4-Trimethylbenzene (mesitylene) is an aromatic hydrocarbon compound commonly present in commercial solvents encompassing their boiling range. Mesitylene are the most common isomer used in commercial applications. Aromatic hydrocarbons in hydrocarbon solvents are predominantly alkylated one ring structures...
Neither of the benzene exposure protocols induced elevated incidences of leukemia/lymphoma in either strain. These studies demonstrate that discontinuous exposures to benzene are tumorigenic and that a lifetime exposure to benzene, even if delivered at a lower concentration and in an intermittent ...
It is estimated that 5280 coal burning stoves per square kilometre are used for cooking in Calcutta. The median concentration of benzene, toluene and xylene in the smoke plume above the coal burning stove used for cooking, was found to be 5497 g m3, 4080 g m3, and 962 g m3 respectively...
By alkylation, chlorination, nitration, andsulfonation, chemicals, such as styrene, phenols, andmalefic anhydride are produced. Benzene is also used inthe manufacture of detergents, explosives, pharmaceuticals;in the manufacture of cyclohexane and ethylbenzene;and dye-stuffs. Increased concern for benzene...
With the increase of concentration, the irritation is enhanced, which can stimulate the skin and respiratory tract. Gastric mucosa is stimulated when eating in a poorly ventilated room. Styrene is different from benzene and does not cause chronic poisoning, because styrene is easily oxidized into ...
However, the exact mechanism by which benzene exerts its strong hematotoxicity is not fully understood. Evidence is mounting that ROS are responsible for the redox-mediated activation of Src, but its roles in apoptosis remain still controversial (Chang et al., 2021, Giannoni et al., 2008). ...
Statistical analysis and I/O (indoor concentration/outdoor concentration) ratio results showed that the main sources of formaldehyde, acetaldehyde, benzene ... Q Liu,Y Liu,M Zhang - 《Building & Environment》 被引量: 38发表: 2013年 Mutagenic Activity of Incense Smoke in Comparison to Formaldehy...
1321-74-0] is in ion-exchange resins for domestic and industrial water softening. Ion-exchange resins are also used as solid acid catalysts for certain reactions, such as esterification. Divinylbenzene is manufactured by dehydrogenation of diethylbenzene, which is an internal product in the alkylati...
