Chapter 5.12 Styrene - World Health Organization
WHO Regional Office for Europe, Copenhagen, Denmark, 2000 1 Chapter Styrene General description Styrene (vinylbenzene, styrole) is a colourless, viscous liquid with a pungent odour and tendency to polymerize. Its chemical structure is and its molecular mass Styrene is slightly soluble in water, soluble in ethanol and very soluble in benzene and petroleum ether. Sources Styrene is one of the most important monomers worldwide, and its polymers and copolymers are used in an increasingly wide range of applications. The major uses are in plastics, latex paints and coatings, synthetic rubbers, polyesters and Styrene -alkyd coatings (1,2).
Styrene has also been detected in drinking-water in the United States at concentrations of less than 1 µg/litre and, specifically, in commercial, charcoal-filtered drinking-water in New Orleans (18). Styrene evaporates readily from water to air. The evaporation half-time of styrene in water at a depth of 1 m is estimated to be about 6 hours.
