Assessment of the consequences of a possible ban on phosphates in household detergents

Abstract
A screening and an initial risk assesment has been carried out for substances that may be introduced as alternatives if a restriction of the use of phosphates in household detergents is introduced. The results of the screening and the risk assessment indicate that a ban of phosphate in laundry detergents will not lead to toxic effects in the aquatic environment.

Effects on Danish wastewater treatment plants from a ban of phosphate will most likely result the in lower operation costs in terms of less use of precipitation chemicals and a lower sludge production. However expenses may be expected for modifications of processes and alterations of buildings and other constructions at the wastewater treatment plant.
