  • European Union Risk Assessment Report: styrene, Part I - environment. CAS No: 100-42-5. EINECS No: 202-851-5. Series: 1st Priority List, Volume 27


The report provides the comprehensive risk assessment of the substance styrene. It has been prepared by the UK in the frame of Council Regulation (EEC) No. 793/93 on the evaluation and control of the risks of existing substances, following the principles for assessment of the risks to man and the environment, laid down in Commission Regulation (EC) No. 1488/94.

The evaluation considers the emissions and the resulting exposure to the environment and the human populations in all life cycle steps. Following the exposure assessment, the environmental risk characterisation for each protection goal in the aquatic, terrestrial and atmospheric compartment has been determined. For human health the scenarios for occupational exposure, consumer exposure and humans exposed via the environment have been examined and the possible risks have been identified.

The environmental risk assessment for styrene concludes that there is at present no concern for the atmosphere, the aquatic ecosystem, the terrestrial ecosystem and for microorganisms in the sewage treatment plant.
