- Regulatory Information： The Australian Inventory of Industrial Chemicals: Chemical: Benzene, 1-ethenyl-3-methyl-
- Effluent Concentrations： Motorboats emitted 3-vinyltoluene to canal water; concentrations were not reported(1). Use of unleaded gasoline by a four-stroke outboard motor emitted 3-vinyltoluene to test water at 6.2 mg/10 min(2). 3-Vinyltoluene was detected in the leachate plume of Norman, OK landfill sampled Nov 1995 and Apr 1996(3).
- Human Toxicity Excerpts： /GENOTOXICITY/ ... In human lymphocytes exposed in whole blood cultures, vinyl toluene induced both sister chromatid exchange and chromosomal aberrations in a dose-dependent manner, in the absence of exogenous metabolic activation. The induction of sister chromatid exchange was dependent on the number of erythrocytes present. Significant increases in the frequencies of sister chromatid exchange were observed in human lymphocytes exposed in whole blood cultures to ortho, meta and para isomer. The strongest responses were seen with the meta and para isomers, which are the dominant species in vinyl toluene.
- ICSC Environmental Data： The substance is toxic to aquatic organisms. Bioaccumulation of this chemical may occur in the environment. It is strongly advised not to let the chemical enter into the environment.
- Packaging and Labelling： Marine pollutant.
- Fire Fighting Procedures： Suitable extinguishing media: Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide. Advice for firefighters: Wear self-contained breathing apparatus for firefighting if necessary. Further information: Use water spray to cool unopened containers.
- Soil Adsorption/Mobility： Using a structure estimation method based on molecular connectivity indices(1), the Koc of 3-vinyltoluene can be estimated to be 720(SRC). According to a classification scheme(2), this estimated Koc value suggests that 3-vinyltoluene is expected to have low mobility in soil(SRC).
- Artificial Pollution Sources： 3-Vinyltoluene's production and use as a laboratory chemical(1) may result in its release to the environment through various waste streams(SRC).
