Additional information

DBDPE is expected to parition in the environment to sediment and soil (ca. 99%). Negligible distribution to air and water are expected. High binding to particulates in all media is expected. Photolysis and hydrolysis are not expected to be significant routes of environmental distribution. Sewage treatment plants are expected to remove > 95% of that present in the influent. Removal is expected to be via binding to particulates rather than biodegradation. Volatilization is not expected. Its characteristic travel distance is expected to be low and long range atmospheric transport is not expected. Its movement in the atmosphere will be governed by the particulates to which it is bound. Atmospheric losses are expected to occur via wet and dry deposition.
