Abstract

Abstract Exposure and effect assessment including risk characterisation of enzymes used in household detergents were conducted. Predicted environmental concentrations were calculated by use of traditional methods and detailed transport and fate modelling. Predicted no effect concentrations were derived from the results of ecotoxicological studies conducted with subtilisin and other available information on the acute and chronic aquatic toxicity. Risk characterisation ratios were defined as the ratio between the predicted environmental concentration and the predicted no effect concentration. Risk characterisation ratios were calculated for fresh and marine water and were found to be between 0.0002 and 0.06, i.e. all well below 1. This shows that under the given conditions, the use of enzymes in household detergents does not present a risk to the aquatic environment.
