The report provides the comprehensive risk assessment of the substance Dimethyl Sulphate. It has been prepared by The Netherlands in the frame of Council Regulation (EEC) No. 793/93 on the evaluation and control of the risks of existing substances.

The evaluation considers the emissions and the resulting exposure to the environment and to human populations. The environmental risk (aquatic, terrestrial and atmospheric) 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 dimethyl sulphate concludes that there is at present concern for workers. For consumers and humans exposed via the environment the risk assessment concludes that a risk cannot be excluded as the substance is identified as a non-threshold carcinogen. The risks though are low and this should be taken into account when considering the feasibility and practicability of further specific risk reduction measures. The risk assessment for the environment concludes that there is at present no concern for the atmosphere, aquatic ecosystem, terrestrial ecosystem or for micro-organisms in the sewage treatment plant from sources of dimethyl sulphate covered by Regulation 793/93. However, more information is needed about actual atmospheric concentrations of dimethyl sulphate from other sources not covered by the Regulation.

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.
