"The report provides the comprehensive risk assessment of the substance Benzene C10-13 alkyl derivates. It has been prepared by Italy 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 the assessment of 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 population in all life cycle steps. Following the exposure assessment, the environmental risk characterisation for each protection target in the aquatic, terrestrial and soil compartment has been determined. For human health the scenarios for occupational exposure, consumer exposure and humans exposed indirectly via the environment have been examined and the possible risks have been identified. The risk assessment for Benzene C10-13 alkyl derivates concludes that there is no concern for the environment and/or for human health."--Editor.
