DTDP is expected to have a half-life in soil similar to DINP, approximately 51 days.
Studies are not available to assess the
biodegradability of DTDP specifically in soil. However, data for an
analog substance di-isononyl phthalate (DINP) can be used to estimate
the loss rate of DTDP in soil. DINP exhibited a half-life in soil of
approximately 51 days, based on the loss of parent substance (ExxonMobil
Biomedical Sciences, Inc., 0545371). These data were developed in an
earthworm toxicity test conducted in soil in which the concentration of
DINP was monitored over a 56-day period. During that period DINP
concentration decreased from 982 to 441 mg/kg soil (wet weight). Because
DTDP and DINP are structural analogs, they would be expected to
biodegrade in soil at similar rates and to similar extents.
