Additional information

Bioaccumulation concentration factor (BCF) cannot not be measured for DPDP due to its rapid hydrolysis. The BCF model estimates for DPDP are also of limited utility given their wide range and the fact that hydrolysis is not considered in the model. Given the rapid hydrolysis, the bioaccumulation potential of the hydrolysis products, phenol, isodecanol and phosphorous acid, were considered. Both are low and well below the criterion for B (bioaccumulative) or vB (very bioaccumulative). As such, it is concluded that DPDP does not meet the criteria for B or vB.
