Ethyl Benzene, Blood Test
This test is used to monitor exposure
to ethyl benzene. Blood is the preferred specimen for measuring an acute or
recent exposure.
Ethyl benzene toxicity can be demonstrated
at air concentrations of 1000 ppm (eg, eye and nose irritation). Increases
in ethyl benzene concentration can produce increasing degrees of CNS depression,
often beginning with lacrimation and dizziness. Ethyl benzene is employed
commercially as a solvent, fuel additive, and chemical intermediate in the
production of styrene. Nonoccupational exposure is unlikely, although ethyl
benzene is a constituent of some of the aromatic solvents used in domestic
products such as paint thinners and adhesives. Blood is the preferred specimen
for measuring acute or recent exposure.
