An environmental risk assessment of alkanes, C14-17, chloro (medium chain chlorinated paraffins or MCCPs) produced in accordance with Council Regulation (EEC) 793/93 was published in December 2005. This report provides the updated risk assessment dealing with new data and the consequences of the new data for the conclusions in the original report. The report has been prepared by the United Kingdom 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.
This report considers the secondary poisoning assessment and the exposure of man via the environment based on new information. This update includes also the PBT assessment which was not addressed in the original report for medium chain chlorinated paraffins.
The updated environmental risk assessment concludes that risks are identified for the earthworm food chain due to various uses of MCCPs. Risks are not identified any longer for the fish food chain, with the exception of the use in leather fat liquors. The exposure of man via environmental routes has been revised with new information. It is now concluded that there is no longer concern for this route of human exposure. The PBT assessment concludes that further information is needed in order to confirm whether or not the substance should be considered as a PBT substance or not. A testing strategy is discussed in the report.
