B-Butyrolactone: Health-based calculated occupational cancer risk values

On request of the Minister of Social Affairs and Employment the Dutch Expert Committee on Occupational Standards (DECOS) estimates the additional lifetime cancer risk associated with occupational exposure to substances that have been classified by the European Union or the DECOS as genotoxic carcinogen. In this report the committee studies if such estimates can calculated for b-butyrolactone. It has used the method described in the report ’Calculating cancer risks due to occupational exposure to genotoxic carcinogens’ (1995/06WGD) (Hea95).

The committee is of the opinion that due to a lack of sufficient data, it is not possible to estimate the additional lifetime cancer risk for b-butyrolactone.
