  • European Union Risk Assessment Report: diphenyl ether, octabromo derivative, CAS No: 32536-52-0 EINECS No: 251-087-9. Series: 1st Priority List, Volume: 16


The report provides the comprehensive risk assessment of the substance diphenyl ether, octabromo derivative. It has been prepared by France and the UK in the frame of Council Regulation (EEC) No. 793/93.

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 human health risk assessment for diphenyl ether, octabromo derivative concludes that there is concern for workers. There is at present no concern for consumers. For humans exposed via the environment and for infants exposed via breast milk, the risk assessment concludes that there is at present a need for further information in order to characterise the risks. The risk assessment for the environment concludes that there is concern for top predators via accumulation up the food chain (secondary poisoning) for at least one emission scenario. There is at present no concern for the atmosphere, aquatic ecosystem, terrestrial ecosystem or for microorganisms in the sewage treatment plant.

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