Bioaccumulation concentration factor (BCF) cannot not be measured for 2 -EHDPP due to its rapid hydrolysis. The BCF model estimates for


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 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

2 -EHDPP d

oes not meet the criteria for B or vB.
