At an exposure of 100 ppm, one may experience nausea or a headache. At an exposure between 200 and 500 ppm, symptoms can include feeling "high", dizziness, weakness, irritability, vomiting, and slowed reaction time. [20] [21] The side effects of exposure to low concentrations of xylene (< 200 ppm) are reversible and do not cause permanent ...
Ethylbenzene is an organic compound with the formula C 6 H 5 CH 2 CH 3. It is a highly flammable, colorless liquid with an odor similar to that of gasoline . This monocyclic aromatic hydrocarbon is important in the petrochemical industry as a reaction intermediate in the production of styrene , the precursor to polystyrene , a common plastic ...
The p-xylene is then separated out in a series of distillation, adsorption or crystallization and reaction processes from the m-xylene, o-xylene, and ethylbenzene. Its melting point is the highest among this series of isomers, but simple crystallization does not allow easy purification due to the formation of eutectic mixtures.
Physical therapist Karin Leland offers some advice for those feeling dizzy or off balance.
Dizziness is a common medical complaint, affecting 20–30% of persons. [4] Dizziness is broken down into four main subtypes: vertigo (~25–50%), disequilibrium (less than ~15%), presyncope (less than ~15%), and nonspecific dizziness (~10%). [5] Vertigo is the sensation of spinning or having one's surroundings spin about them. Many people find ...
Chronic solvent-induced encephalopathy (CSE) is a condition induced by long-term exposure to organic solvents, often—but not always—in the workplace, that lead to a wide variety of persisting sensorimotor polyneuropathies and neurobehavioral deficits even after solvent exposure has been removed.
Symptoms can include: [citation needed] A constant sense of unsteadiness, rocking or swaying, dizziness or lightheadedness; Disequilibrium on most days for at least 3 months; Spatial orientation problems; Off-kilter sensation; Extreme sensitivity to movement and/or complex visual stimuli such as grocery stores or driving in certain weather ...
Several other identified toxic gases emitted (following the interaction of the chemicals concerned with water and air) include acrolein, acrylonitrile, ethylbenzene, hydrogen chloride, D-limonene, toluene and xylene, which if inhaled, can cause headache, nausea, fainting and breathing difficulty.
