The report provides the comprehensive risk assessment of the substance hydrogen peroxide. It has been prepared by Finland 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 humans 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 hydrogen peroxide concludes that there is concern for the aquatic ecosystem arising from four production sites and use in manufacture of other chemicals. There is no concern for the atmosphere, the terrestrial ecosystem and microorganisms in the sewage treatment plant.

The human health risk assessment for hydrogen peroxide concludes that there is concern for workers and consumers while no concern was identified for humans exposed via the environment.

The conclusions of this report will lead to risk reduction measures to be proposed by the Commissions committee on risk reduction strategies set up in support of Council Regulation (EEC) N. 793/93.
